Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a method and system for generating a construction cost control management report applied to a construction project. Background Art

[0002] In the field of construction engineering, project cost control is a key link to ensure the economic and feasibility of the project. Traditional methods of project cost control often rely on manual experience and simple data analysis, which makes it difficult to fully and accurately grasp the cost control of each component in the project. With the rapid development of building information modeling (BIM) technology, BIM engineering models have become an important tool in the design and construction process of construction projects. They can integrate the geometric information, physical information and functional information of construction projects, providing new opportunities for project cost control.

[0003] However, the existing BIM-based construction cost control methods still have many shortcomings. On the one hand, these methods often only focus on the cost control of a single engineering component, while ignoring the correlation and mutual influence between components, resulting in limited control effects. On the other hand, the lack of intelligent cost control guidance information makes it impossible to dynamically adjust the control strategy according to the actual situation of the project, making the control process lack flexibility and accuracy.

[0004] Therefore, there is an urgent need for a method that can comprehensively consider the correlation between engineering components, provide intelligent cost control guidance information, and automatically generate systematic and accurate engineering cost control management reports, so as to overcome the shortcomings of existing technologies and improve the cost control level and management efficiency of construction projects. Summary of the invention

[0005] In view of the above-mentioned problems, in combination with the first aspect of the present invention, an embodiment of the present invention provides a method for generating a construction cost control management report for a construction project, the method comprising:

[0006] Acquire a BIM engineering model to be subjected to engineering cost control uploaded by a BIM model management system; the BIM engineering model includes a plurality of engineering component data to be subjected to engineering cost control;

[0007] Acquire cost control guidance information of the BIM engineering model; the cost control guidance information includes engineering association knowledge data between the plurality of engineering component data, and cost control knowledge data of each engineering component data under the engineering association knowledge data; the cost control knowledge data of any engineering component data represents the predicted control cost information estimated from the start of engineering cost control of the corresponding engineering component data to the completion of engineering cost control of all engineering component data in the association knowledge path of the corresponding engineering component data;

[0008] Arranging the plurality of engineering component data based on the engineering-related knowledge data and the cost control knowledge data of each engineering component data to generate an engineering cost control order for the plurality of engineering component data;

[0009] In the process of engineering cost control of the BIM engineering model, engineering cost control is performed on the multiple engineering component data according to the engineering cost control order, an engineering cost control management report of the BIM engineering model is generated, and the engineering cost control management report is sent to the BIM model management system.

[0010] On the other hand, an embodiment of the present invention also provides a construction cost control management report generation system for construction projects, including a processor and a machine-readable storage medium, the machine-readable storage medium is connected to the processor, the machine-readable storage medium is used to store programs, instructions or codes, and the processor is used to execute the programs, instructions or codes in the machine-readable storage medium to implement the above method.

[0011] Based on the above aspects, the embodiment of the present application realizes the refined management and control of multiple engineering component data in the construction project by obtaining the BIM engineering model and its cost control guidance information uploaded by the BIM model management system. This method not only takes into account the engineering related knowledge data between the engineering component data, but also deeply mines the cost control knowledge data of each engineering component data under the associated knowledge path, so as to accurately predict and evaluate the predicted control cost information of each engineering component in the cost control process. Based on this, the present invention can intelligently generate the engineering cost control order of multiple engineering component data, ensuring the scientificity and rationality of engineering cost control. In the engineering cost control process of the BIM engineering model, orderly control is carried out according to this order, which not only improves the control efficiency, but also effectively avoids the additional cost expenditure caused by improper control order. The engineering cost control management report finally generated provides comprehensive and accurate cost control information for the construction project, which helps to improve the overall management level of the construction project.

[0013] Figure 2 It is a schematic diagram of the hardware architecture of a construction cost control management report generation system for construction projects provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0014] The present invention will be described in detail below with reference to the accompanying drawings. Figure 1It is a flow chart of a method for generating a construction cost control management report for a construction project provided by an embodiment of the present invention. The method for generating a construction cost control management report for a construction project is introduced in detail below.

[0015] Step S110, obtaining a BIM project model uploaded by a BIM model management system for project cost control, wherein the BIM project model includes a plurality of project component data for project cost control.

[0016] In this embodiment, for a BIM engineering model of a certain construction project, the construction project is a comprehensive commercial building, covering multiple functional areas, such as shopping malls, office areas, parking lots, etc. This BIM engineering model is managed and maintained by the BIM model management system. During the construction process of the construction project, in order to effectively control the construction cost, the BIM engineering model needs to be uploaded to a specific construction cost control system.

[0017] In this BIM engineering model, multiple engineering component data include various parts of the building. For example, the engineering component data of the basic structure includes the relevant data of various types of foundation piles (such as cast-in-place piles, precast piles, etc.), which covers the size, material, construction process and other information of the piles, which is crucial for engineering cost control. There are also engineering component data of the main structure of the building, such as the relevant data of concrete columns, beams, and slabs, including their cross-sectional dimensions, concrete strength grade, steel bar configuration, etc. For the facade of the building, the curtain wall engineering component data is also included, such as the type of curtain wall (glass curtain wall, stone curtain wall, etc.), the structure of the curtain wall, the material specifications used, etc. In addition, the engineering component data of the mechanical and electrical equipment installation inside the building is also in this model, including the relevant data of the distribution cabinet, cable tray, lighting equipment, etc. in the electrical system, and the relevant data of pipes, valves, sanitary appliances, etc. in the water supply and drainage system. These numerous engineering component data constitute the entire BIM engineering model, each of which has different characteristics and cost influencing factors, and is the basis for subsequent engineering cost control. When the BIM model management system uploads the BIM engineering model containing rich engineering component data, the engineering cost control system obtains the BIM engineering model to be subject to engineering cost control.

[0018] Step S120, obtaining cost control guidance information of the BIM engineering model. The cost control guidance information includes engineering association knowledge data between the multiple engineering component data, and cost control knowledge data of each engineering component data under the engineering association knowledge data. The cost control knowledge data of any engineering component data represents the predicted control cost information expected from the activation of engineering cost control for the corresponding engineering component data to the completion of engineering cost control for all engineering component data in the associated knowledge path of the corresponding engineering component data.

[0019] Continuing with the BIM engineering model of the commercial building mentioned above as an example, the acquisition of cost control guidance information has a clear source and content. For engineering-related knowledge data, taking the structural part of the building as an example, there is a close engineering-related knowledge data between the foundation structure and the main structure. The stability of the foundation structure directly affects the safety and construction process of the main structure. This association is reflected in the data. For example, the layout and depth of the foundation piles will affect the positioning and bearing capacity calculation of the main structure columns. In terms of cost control knowledge data, it is assumed that engineering cost control is enabled from the foundation piles (engineering component data) first. If the foundation piles use the cast-in-place pile construction process, its cost control knowledge data will take into account the predicted control cost information expected from the construction of cast-in-place piles to the subsequent engineering component data associated with it (such as the foundation pedestal construction after the cast-in-place pile construction is completed, and then to the construction of the upper main structure columns, etc., all engineering component data in this associated knowledge path) to complete the engineering cost control. This predicted control cost information includes material costs, labor costs, machinery and equipment rental costs, and possible risk costs.

[0020] Let's look at the association between the engineering component data of electromechanical equipment installation and the engineering component data of the main structure of the building. In terms of engineering-related knowledge data, the location and size of the reserved holes in the floor slab in the main structure must match the pipeline laying path in the electromechanical equipment installation, otherwise it will increase additional construction costs. For the engineering component data of the distribution cabinet in the electromechanical equipment installation, its cost control knowledge data will consider all engineering component data in the associated knowledge path from the installation of the distribution cabinet to the laying of the cable tray and lighting equipment wiring associated with it to complete the predicted control cost information expected by the engineering cost control. This may involve the purchase cost of the distribution cabinet itself, the installation labor cost, and the cost changes caused by the impact of the installation location of the distribution cabinet on the subsequent cable tray and lighting equipment installation (such as the additional material and labor costs of the bridge needing to bypass the distribution cabinet). The cost control guidance information can be obtained by a team of experts with rich experience in construction engineering cost based on the data and experience of previous similar projects, and then this information is provided to the engineering cost control system after being associated with the engineering component data in the BIM engineering model. It can also be the result of analyzing and mining a large amount of historical data of construction projects.

[0021] Step S130 , arranging the plurality of engineering component data based on the engineering-related knowledge data and the cost control knowledge data of each engineering component data, and generating an engineering cost control order for the plurality of engineering component data.

[0022] Still taking the commercial building project as an example, the engineering component data is arranged based on the engineering-related knowledge data and the cost control knowledge data. First, based on the engineering-related knowledge data, the first engineering component data belonging to the first arrangement order level is determined. For this commercial building project, some independent foundation components in the foundation engineering may be the first engineering component data, because these independent foundation components are relatively independent in the entire building structure system, and there is no directly associated pre-engineering component data. For example, some independent foundations are directly located on the original soil foundation and can be constructed without relying on other basic structural components. Then, based on the comparison results between the cost control knowledge data of each independent foundation component, their engineering cost control order at the first arrangement order level is determined. Assume that one of the independent foundation components A has relatively low construction difficulty due to its good geological conditions, and the estimated prediction control cost information is low, such as short material transportation distance, no special foundation treatment process, etc., while the other independent foundation component B is located in an area with a high groundwater level and requires precipitation treatment and special foundation reinforcement, and its prediction control cost information is high. Therefore, at the first arrangement order level, the engineering cost control order of component A may be higher than that of component B.

[0023] Next, based on the engineering-related knowledge data, the second engineering component data belonging to the second ranking order level is determined. In this project, the foundation cap can be regarded as the second engineering component data because it is associated with the first engineering component data (independent foundation component). The cost control knowledge data of each foundation cap is different. For example, the size of foundation cap C is larger, the amount of concrete used is large, and the steel bar configuration is complex. Its cost control knowledge data shows that its predicted control cost is higher, while the size of foundation cap D is smaller, the structure is relatively simple, and the predicted control cost is lower. Based on the comparison results between these cost control knowledge data, the engineering cost control order of each foundation cap under the second ranking order level is determined, and the engineering cost control order of cap D may be earlier than that of cap C.

[0024] Further determine the subsequent engineering component data that belongs to the subsequent arrangement order level, such as the column components in the main structure. The column components are engineering-related to the foundation pedestal. The cost control knowledge data of the column components needs to consider the predicted control cost information from the construction of the column components to the completion of the construction of the associated beams, slabs and other components. If the height of column component E is high, it needs to be reinforced with high-strength concrete and more steel bars, and its predicted control cost is high, while the situation of column component F is relatively simple, then at its corresponding arrangement order level, the engineering cost control order of column component F may be ahead of column component E. Through such step-by-step analysis and comparison, multiple engineering component data in the entire BIM engineering model are arranged, and finally the engineering cost control order is generated.

[0025] Step S140, during the engineering cost control process of the BIM engineering model, engineering cost control is performed on the multiple engineering component data according to the engineering cost control order, an engineering cost control management report of the BIM engineering model is generated, and the engineering cost control management report is sent to the BIM model management system.

[0026] The engineering cost control is carried out according to the engineering cost control sequence generated by the commercial building project mentioned above. First, control is started from the engineering component data in the front, for example, from the independent foundation component A. During the construction process, the costs of material procurement, labor use, machinery and equipment rental, etc. are strictly monitored and managed in accordance with the budget and cost control requirements. Assuming that in the construction of the independent foundation component A, through effective cost control measures, material procurement is carried out according to the predetermined price and quality standards, labor hours do not exceed the budget, and the machinery and equipment rental time is also within a reasonable range, then the second engineering component data implementation result of the independent foundation component A is obtained. Then, the engineering cost control of the foundation pedestal D is carried out in order, and its various costs are also monitored to ensure that the construction is carried out within the range of the predicted control cost information predicted by its cost control knowledge data.

[0027] In the process of engineering cost control of the entire BIM engineering model, such control operations are performed on each engineering component data in turn. It is assumed that the implementation results of the first engineering component data of all engineering component data match the implementation results of the second engineering component data, that is, the results of each engineering component data in the actual engineering cost control process are consistent with the expected cost control knowledge data. For example, the beams and plate components in the main structure, the various equipment and pipeline components in the installation of electromechanical equipment, etc., the costs in the actual construction process are within the predicted range. Then a project cost control management report for the BIM engineering model engineering cost control is generated. This report records in detail the cost control of each engineering component data, including the original budget, actual expenditure, cost savings or overspending reasons analysis. Finally, this project cost control management report is sent to the BIM model management system so that the BIM model management system can evaluate the overall situation of the project and make further decisions based on this report, such as whether it is necessary to adjust the BIM engineering model construction and cost control strategy for subsequent similar projects.

[0028] Based on the above steps, the embodiment of the present application realizes the refined management and control of multiple engineering component data in the construction project by obtaining the BIM engineering model and its cost control guidance information uploaded by the BIM model management system. This method not only takes into account the engineering related knowledge data between the engineering component data, but also deeply mines the cost control knowledge data of each engineering component data under the associated knowledge path, so as to accurately predict and evaluate the predicted control cost information of each engineering component in the cost control process. Based on this, the present invention can intelligently generate the engineering cost control order of multiple engineering component data, ensuring the scientificity and rationality of engineering cost control. In the engineering cost control process of the BIM engineering model, orderly control is carried out according to this order, which not only improves the control efficiency, but also effectively avoids the additional cost expenditure caused by improper control order. The engineering cost control management report finally generated provides comprehensive and accurate cost control information for the construction project, which helps to improve the overall management level of the construction project.

[0029] In a possible implementation, step S130 includes:

[0030] Step S131, based on the engineering-related knowledge data, determine first engineering component data belonging to a first arrangement order level among the plurality of engineering component data. The first engineering component data indicates engineering component data for which there is no associated engineering component data among the plurality of engineering component data.

[0031] Step S132: determining the engineering cost control order of each of the first engineering component data at the first arrangement order level based on the comparison result between the cost control knowledge data of each of the first engineering component data.

[0032] Step S133: based on the engineering-related knowledge data, determine second engineering component data belonging to a second arrangement order level from among the plurality of engineering component data. The second engineering component data represents engineering component data associated with the first engineering component data from among the plurality of engineering component data.

[0033] Step S134: determining the engineering cost control order of each of the second engineering component data at the second arrangement order level based on the comparison result between the cost control knowledge data of each of the second engineering component data.

[0034] Step S135, further determining the subsequent engineering component data belonging to the subsequent arrangement order level, and determining the engineering cost control order of each of the subsequent engineering component data under the subsequent arrangement order level, the engineering cost control order of the first arrangement order level is prior to the second arrangement order level.

[0035] In a possible implementation, the cost control guidance information is extracted from an engineering cost control network. The engineering cost control network includes control entities and directional links, the control entities in the engineering cost control network are used to characterize engineering component data in the BIM engineering model, the control entity characteristics of the control entities in the engineering cost control network are used to characterize cost control knowledge data of engineering component data in the BIM engineering model, and the directional links in the engineering cost control network are used to characterize engineering association knowledge data between engineering component data in the BIM engineering model.

[0036] The directional link connected to the target control entity in the engineering cost control network includes at least one of the following: an input link and an output link. The input link of the target control entity is used to indicate that the target control entity is associated with other control entities, and the other control entities are connected to the target control entity based on the input link of the target control entity. The output link of the target control entity is used to indicate that the target control entity is associated with a designated control entity, and the designated control entity is connected to the target control entity based on the output link of the target control entity. The target control entity represents any control entity in the engineering cost control network.

[0037] The first engineering component data represents the engineering component data used to represent by the first control entity in the engineering cost control network, and the first control entity has an output link but no input link. The second engineering component data represents the engineering component data used to represent by the second control entity in the engineering cost control network, and the second control entity is connected to the output link of the first control entity.

[0038] In this embodiment, taking the commercial building project mentioned above as an example, firstly, the first engineering component data belonging to the first ranking level in multiple engineering component data is determined based on the engineering-related knowledge data. For the BIM engineering model of the commercial building project, among the numerous engineering component data, the site leveling engineering component data can be regarded as the first engineering component data. Site leveling is the starting work of the construction project. In the entire engineering component data system, it does not have associated engineering component data as a prerequisite, that is, it does not need to rely on the completion of other engineering components to proceed. Its cost control knowledge data includes relevant cost information such as site cleaning, earth excavation and backfilling, and the use of site leveling machinery.

[0039] Next, based on the comparison results between the cost control knowledge data of each first engineering component data, the engineering cost control order of each first engineering component data under the first ranking order level is determined. Assume that in addition to site leveling, temporary facility construction engineering component data also belongs to the category of first engineering component data. The cost control knowledge data of site leveling shows that its main cost is concentrated in earthwork engineering. Due to the good geological conditions of the site, the earthwork excavation volume is relatively small, the mechanical equipment rental cost is low, and the estimated total cost is relatively low. As for the temporary facility construction engineering component data, since it is necessary to meet the needs of office, accommodation, material stacking, etc. during the entire project construction period, the scale is large, and more temporary building materials need to be purchased, and site planning and facility layout are required. Its cost control knowledge data shows that the estimated total cost is high. Therefore, under the first ranking order level, the engineering cost control order of site leveling precedes that of temporary facility construction.

[0040] Then, the second engineering component data belonging to the second ranking level is determined based on the engineering-related knowledge data. For commercial building projects, the independent foundation engineering component data in the foundation engineering can be used as the second engineering component data because it is associated with the first engineering component data. For example, the construction positioning and excavation of the independent foundation can only be carried out after the site is leveled. The cost control knowledge data of the independent foundation covers the cost of foundation materials (such as concrete, steel bars, etc.), the labor cost of foundation construction, and the rental cost of foundation construction equipment (such as excavators, concrete mixers, etc.). Different independent foundations have different design sizes and load-bearing requirements, so the cost control knowledge data is also different.

[0041] Based on the comparison results between the cost control knowledge data of each second engineering component data, the engineering cost control order of each second engineering component data under the second ranking order level is determined. Assuming that there are two independent foundations, independent foundation A has a lower design bearing capacity and a smaller size. It requires relatively less concrete and steel bars, and the construction difficulty is also lower. Therefore, the cost control knowledge data shows that its estimated total cost is lower. Independent foundation B has high bearing capacity requirements, large size, and is located in an area with a high groundwater level. It requires special waterproofing and reinforcement measures. The cost control knowledge data shows that its estimated total cost is higher. Therefore, under the second ranking order level, the engineering cost control order of independent foundation A precedes that of independent foundation B.

[0042] Further determine the subsequent engineering component data belonging to the subsequent arrangement order level and determine its engineering cost control order at the corresponding level. The main structure engineering component data after the independent foundation, such as the column engineering component data, belongs to the subsequent arrangement order level. The column engineering component data is associated with the independent foundation engineering component data. The cost control knowledge data of the column includes the column body concrete pouring cost, the column internal steel bar configuration cost, and the column formwork installation cost. Considering the columns in different positions, such as the bottom column, which may require a larger cross-sectional size and more steel bars due to the greater load it bears, the cost control knowledge data shows that its estimated cost is higher, while the columns in the high-rise part have a relatively small load and a lower cost. Therefore, in this subsequent arrangement order level, the engineering cost control order of the high-rise part columns precedes the bottom-level columns.

[0043] In terms of extracting cost control guidance information from the engineering cost control network, the construction of the engineering cost control network for a commercial building project is taken as an example. The control entity in the engineering cost control network is used to represent the engineering component data in the BIM engineering model. For example, the pile foundation engineering component data in the foundation engineering is represented as a control entity in the engineering cost control network. The control entity characteristics of the control entity in the engineering cost control network are used to represent the cost control knowledge data of the engineering component data in the BIM engineering model. For the pile foundation control entity, its control entity characteristics include cost-related information under the influence of factors such as pile type (such as friction pile or end-bearing pile), pile length, and pile diameter, such as the material cost of different pile types, the construction process cost, etc. The directional link in the engineering cost control network is used to represent the engineering association knowledge data between the engineering component data in the BIM engineering model. For example, there is a directional link between the pile foundation and the cap, which represents the engineering association relationship between them, that is, the cap construction is carried out only after the pile foundation construction is completed.

[0044] The directional links connected to the target control entity in the engineering cost control network include input links and output links. Taking the control entity corresponding to the beam engineering component data in the main structure in the engineering cost control network as an example, if the column is regarded as the target control entity, there is an association relationship between the column and the beam, and the beam has an input link relative to the column, which means that the beam is associated with the column, and the construction of the beam requires the completion of the construction of the column as a prerequisite, that is, the beam control entity is connected to the column based on the input link of the column target control entity. At the same time, the beam has an output link to the control entity corresponding to the subsequent plate engineering component data, which means that the beam is associated with the plate, and the construction of the plate requires the completion of the construction of the beam as a prerequisite, and the plate, the designated control entity, is connected to the beam based on the output link of the beam target control entity.

[0045] The first engineering component data represents the engineering component data represented by the first control entity in the engineering cost control network, and the first control entity has an output link but no input link. Still taking the site leveling engineering component data as an example, the corresponding first control entity in the engineering cost control network has no input link because it does not need to rely on the completion of other engineering components to start, but it has an output link. After the site leveling is completed, it will be output to the control entity corresponding to the subsequent engineering component data such as foundation engineering, providing construction site preparation for subsequent projects.

[0046] The second engineering component data represents the engineering component data represented by the second control entity in the engineering cost control network, and the second control entity is connected to the output link of the first control entity. For example, the second control entity corresponding to the independent foundation engineering component data is connected to the output link of the first control entity corresponding to the site leveling engineering component data, which means that the construction of the independent foundation is carried out after the site leveling is completed. This link relationship in the engineering cost control network accurately reflects the engineering association relationship between the engineering component data and the logical order of cost control.

[0047] In a possible implementation, step S120 includes:

[0048] Step S121, obtaining the cost control guidance information uploaded by the BIM model management system. Or,

[0049] Step S122, obtaining the model implementation guidance information uploaded by the BIM model management system, and generating the cost control guidance information based on the model implementation guidance information.

[0050] The model implementation guidance information includes the engineering-related knowledge data and the component implementation guidance information of each engineering component data. The component implementation guidance information of any engineering component data represents the control cost information for implementing the corresponding engineering component data.

[0051] In a possible implementation, step S122 includes:

[0052] Step S1221, constructing a model implementation network based on the model implementation guidance information.

[0053] Step S1222, converting the model implementation network into a project cost control network.

[0054] Step S1223, extracting the cost control guidance information from the engineering cost control network.

[0055] In this embodiment, for the method of directly obtaining the cost control guidance information uploaded by the BIM model management system, in the commercial building project, the BIM model management system may have pre-organized the cost control guidance information based on the experience data of previous similar projects, industry standards and specific requirements of the project when managing the BIM engineering model of the entire commercial building. These cost control guidance information covers the engineering association knowledge data between engineering component data, such as the association between the foundation engineering component data and the main structure engineering component data, such as the bearing capacity of the foundation and the distribution and load transfer relationship between the main structure columns; it also includes the cost control knowledge data of each engineering component data, such as the pile foundation in the foundation engineering, whose cost control knowledge data includes the selection of piles (such as selecting different types of piles according to geological conditions), the influence of the construction process of piles on the cost, etc. The BIM model management system directly uploads these comprehensive and organized cost control guidance information, and the engineering cost control system can perform subsequent engineering cost control operations after obtaining this information.

[0056] Another way is to obtain the model implementation guidance information uploaded by the BIM model management system, and then generate cost control guidance information based on it. For commercial building projects, the engineering-related knowledge data in the model implementation guidance information describes the construction sequence and interdependence between engineering components. For example, the engineering-related knowledge data between the electromechanical equipment installation engineering component data and the building main structure engineering component data indicate that the reserved holes and embedded parts in the main structure must be set according to the requirements of electromechanical equipment installation, because the installation path of the electromechanical equipment depends on these settings of the main structure. The component implementation guidance information of each engineering component data represents the control cost information of implementing the corresponding engineering component data. Taking the curtain wall engineering component data of the building facade as an example, its component implementation guidance information includes the procurement cost of curtain wall materials, the labor cost of curtain wall installation, and the rental cost of mechanical equipment required for curtain wall construction.

[0057] When constructing a model implementation network based on model implementation guidance information, take a commercial building project as an example. The engineering component data in the BIM engineering model is used as the control entity in the model implementation network, such as the raft foundation engineering component data in the foundation engineering as a control entity. The component implementation guidance information of the engineering component data in the BIM engineering model is used as the control entity characteristics of the control entity in the model implementation network. For the raft foundation control entity, the concrete pouring cost, steel bar configuration cost, etc. in its component implementation guidance information become its control entity characteristics. Then, the engineering association knowledge data between the engineering component data in the BIM engineering model is used as the directional link between the corresponding control entities in the model implementation network. For example, the engineering association knowledge data between the raft foundation and the upper main structure column is reflected in the model implementation network as the directional link between the raft foundation control entity and the main structure column control entity, indicating that the construction of the column is carried out after the raft foundation construction is completed.

[0058] The process of converting the model implementation network into the engineering cost control network is still explained by the commercial building project. In the model implementation network, the control entity corresponds to the engineering component data, the control entity feature corresponds to the component implementation guidance information, and the directional link corresponds to the engineering association knowledge data between the engineering component data. By analyzing the element relationships contained in the model implementation network, the model implementation network element relationship is generated. This relationship clarifies the role and association of each element in the conversion to the engineering cost control network. For example, the initial control entity in the engineering cost control network is determined based on the starting position of the raft foundation in the entire cost control process (it is an important part of the foundation project and has an important impact on subsequent projects). For the initial control entity, the corresponding component implementation guidance information is converted. For example, the component implementation guidance information of the raft foundation was originally based on the simple construction implementation cost. After the conversion, it should reflect the preliminary characteristics of the predicted control cost information expected from the start of engineering cost control of the raft foundation to all engineering component data in the associated knowledge path (such as from the raft foundation to the upper structure columns, beams, plates and other components) to complete the engineering cost control. This may require comprehensive consideration of the impact of the raft foundation construction on subsequent projects, such as the potential cost caused by the impact of the raft foundation construction accuracy on the upper structure construction. Along the directional link, the cost control related attributes of the control entity associated with the initial control entity are expanded, such as the cost control related attributes of the main structure column control entity are expanded, and the updated cost control related attributes of the control entity associated with the initial control entity with the directional link are generated. Finally, according to the cost control related attributes of the updated control entity, the directional link is adjusted. Based on the adjusted directional link, all control entity characteristics in the engineering cost control network are adjusted again. All control entities are connected according to the adjusted directional link, and each control entity is given the improved control entity characteristics to construct a complete engineering cost control network.

[0059] When extracting cost control guidance information from the engineering cost control network, in the constructed engineering cost control network, the control entity is used to represent the engineering component data in the BIM engineering model, the control entity characteristics of the control entity are used to represent the cost control knowledge data of the engineering component data in the BIM engineering model, and the directional link is used to represent the engineering association knowledge data between the engineering component data in the BIM engineering model. By parsing these network elements, the engineering association knowledge data between the engineering component data and the cost control knowledge data of each engineering component data can be accurately extracted. These data together constitute the cost control guidance information and provide a basis for subsequent engineering cost control work.

[0060] In a possible implementation, step S1221 includes:

[0061] Step S1221-1, using the engineering component data in the BIM engineering model as the control entity in the model implementation network.

[0062] Step S1221 - 2 , using the component implementation guidance information of the engineering component data in the BIM engineering model as the control entity feature of the control entity in the model implementation network.

[0063] Step S1221-3, using the engineering-related knowledge data between the engineering component data in the BIM engineering model as directional links between corresponding control entities in the model implementation network.

[0064] Wherein, the directional link connected to the target control entity in the model implementation network includes at least one of the following: an input link and an output link. The input link of the target control entity is used to represent that the target control entity is associated with other control entities, and the other control entities are connected to the target control entity based on the input link of the target control entity. The output link of the target control entity is used to represent that the target control entity is associated with a designated control entity, and the designated control entity is connected to the target control entity based on the output link of the target control entity. The target control entity represents any control entity in the model implementation network.

[0065] In this embodiment, taking the commercial building project as an example, when constructing the model implementation network, the engineering component data in the BIM engineering model is first used as the control entity in the model implementation network. For the commercial building project, its engineering component data is numerous and complex. For example, various types of foundation component data in the foundation engineering, such as pile foundation (including different types of pile foundation component data such as cast-in-place piles and precast piles), raft foundation component data, etc., are all regarded as control entities in the model implementation network. The column component data, beam component data, and plate component data in the main structure are also control entities. There are also curtain wall component data on the building facade, distribution cabinet component data in the internal electromechanical equipment installation project, cable bridge component data, pipeline component data in the water supply and drainage system, etc. These engineering component data all correspond one by one to become control entities in the model implementation network.

[0066] Next, the component implementation guidance information of the engineering component data in the BIM engineering model is used as the control entity characteristics of the control entity in the model implementation network. Taking the pile foundation component data as an example, its component implementation guidance information includes many aspects. In terms of the materials of the pile foundation, different types of piles use different materials. For example, cast-in-place piles require concrete, steel bars and other materials, while prefabricated piles have their own specific prefabricated component materials. The procurement cost, transportation cost and other information of these materials belong to the component implementation guidance information, which become the control entity characteristics of the pile foundation control entity in the model implementation network. In terms of the construction technology of the pile foundation, such as the different construction costs and construction efficiencies corresponding to the hole-making methods of cast-in-place piles (rotary drilling, impact drilling, etc.), they are also used as the control entity characteristics of the pile foundation control entity. Looking at the column component data again, the cost information corresponding to factors such as the concrete strength grade, the specification and model of the steel bars, and the column formwork type in its component implementation guidance information all become the control entity characteristics of the column control entity in the model implementation network. For curtain wall component data, component implementation guidance information such as the material cost determined by the curtain wall type (glass curtain wall, stone curtain wall, etc.), the labor cost corresponding to the installation process, and the required auxiliary material cost are all converted into control entity characteristics of the curtain wall control entity in the model implementation network.

[0067] Then, the engineering-related knowledge data between engineering component data in the BIM engineering model is used as the directional links between the corresponding control entities in the model implementation network. Taking the relationship between the foundation engineering and the main structure engineering as an example, the main structure column can only be constructed after the pile foundation or raft foundation is completed. This engineering-related knowledge data is reflected in the model implementation network as the directional link between the control entity corresponding to the foundation engineering component data (pile foundation or raft foundation control entity) and the control entity corresponding to the main structure column component data. For the inside of the main structure, the beam construction is carried out after the column construction is completed, and the plate construction is carried out after the beam construction is completed. This series of engineering-related knowledge data is reflected in the model implementation network as the directional links between the column control entity to the beam control entity and the beam control entity to the plate control entity. Let's look at the relationship between the electromechanical equipment installation project and the main structure of the building. The floor slab in the main structure needs to reserve holes to meet the laying requirements of the cable tray and pipeline in the electromechanical equipment installation project. This kind of associated knowledge data is reflected in the model implementation network as the directional link between the main structure floor slab control entity and the cable tray control entity and the pipeline control entity.

[0068] In the model implementation network, the directional links connected to the target control entity include input links and output links. The target control entity represents any control entity in the model implementation network. Taking the control entity corresponding to the beam component data as an example, when considering the control entity corresponding to the column component data, the beam has an input link to the column. This means that the target control entity of the beam is associated with the other control entity of the column, and the other control entity of the column is connected to the beam based on the input link of the beam. This input link represents the order of construction, that is, the completion of the column construction is a prerequisite for the construction of the beam. Starting from the control entity of the beam, when considering the control entity corresponding to the plate component data, the beam has an output link to the plate. This shows that the target control entity of the beam is associated with the designated control entity of the plate, and the designated control entity of the plate is connected to the beam based on the output link of the beam, which means that the completion of the construction of the beam is a prerequisite for the construction of the plate.

[0069] Taking the control entity corresponding to the component data of the distribution cabinet in the electromechanical equipment installation project as an example, when considering the control entity corresponding to the component data of the power supply line laying project, the distribution cabinet has an output link for the power supply line laying. This means that the target control entity of the distribution cabinet is associated with the designated control entity of the power supply line laying, and the designated control entity of the power supply line laying is connected to the distribution cabinet based on the output link of the distribution cabinet, because the power supply line is laid only after the installation of the distribution cabinet is completed. When considering the power supply source (such as the control entity corresponding to the relevant engineering component data such as the substation), the distribution cabinet has an input link for the power supply source, which means that the target control entity of the distribution cabinet is associated with the other control entity of the power supply source, and the other control entity of the power supply source is connected to the distribution cabinet based on the input link of the distribution cabinet, because the distribution cabinet needs the power supply source to provide power to work normally.

[0070] For the control entity corresponding to the water tank component data in the water supply and drainage system, when considering the control entity corresponding to the water inlet pipeline engineering component data, the water tank has an input link to the water inlet pipeline, which means that the target control entity of the water tank is associated with the other control entity of the water inlet pipeline, and the other control entity of the water inlet pipeline is connected to the water tank based on the input link of the water tank, because the water tank needs the water inlet pipeline to provide water. When considering the control entity corresponding to the water outlet pipeline engineering component data, the water tank has an output link to the water outlet pipeline, which means that the target control entity of the water tank is associated with the designated control entity of the water outlet pipeline, and the designated control entity of the water outlet pipeline is connected to the water tank based on the output link of the water tank, because the water in the water tank needs to be transported through the water outlet pipeline. By mapping the relationship between the engineering component data to the directional links between the control entities in the model implementation network in this way, a model implementation network that reflects the engineering implementation logic of the commercial building project can be accurately constructed, laying a solid foundation for its subsequent conversion into an engineering cost control network.

[0071] In a possible implementation, step S1222 includes:

[0072] Based on the control entities, control entity characteristics and directional links contained in the model implementation network, the model implementation network element relationship is generated, wherein the control entity corresponds to the engineering component data, the control entity characteristic corresponds to the component implementation guidance information, the directional link corresponds to the engineering association knowledge data between the engineering component data, and the model implementation network element relationship is used to represent the role and association method of each element in the conversion into the engineering cost control network.

[0073] According to the network element relationship implemented in the model, the initial control entity in the engineering cost control network is determined, and the determination of the initial control entity is based on the starting position or logical starting point of the engineering component data in the entire cost control process.

[0074] For the initial control entity, the corresponding component implementation guidance information is converted to generate the cost control related attributes of the converted initial control entity, which reflects the preliminary characteristics of the predicted control cost information expected from the activation of engineering cost control for a single engineering component data to the completion of engineering cost control for all engineering component data in the associated knowledge path. By analyzing the relationship between the initial control entity and other related control entities in the model implementation network, the component implementation guidance information is preliminarily converted into the preliminary characteristics of the predicted control cost information reflecting the overall cost control concept.

[0075] Along the directional link, the cost control related attributes of the control entity associated with the initial control entity are expanded to generate updated cost control related attributes of the control entity associated with the initial control entity by the directional link.

[0076] According to the cost control related attributes of the updated control entity, the directional link is adjusted. Based on the adjusted directional link, all control entity characteristics in the engineering cost control network are adjusted again. All control entities are connected according to the adjusted directional link, and each control entity is given the improved control entity characteristics to build a complete engineering cost control network.

[0077] In this embodiment, a commercial building project is taken as an example to illustrate the process of converting a model implementation network into a construction cost control network in a detailed scenario.

[0078] In the model implementation network of the commercial building project, control entities such as the pile foundation control entity in the foundation engineering, the column control entity, beam control entity, and slab control entity in the main structure, and the distribution cabinet control entity in the electromechanical equipment installation engineering, etc., correspond to the engineering component data respectively. Control entity characteristics, for example, the characteristics of the pile foundation control entity include the type of pile (cast-in-place pile or precast pile), pile diameter, pile length and other cost factors involved in the component implementation guidance information; the characteristics of the column control entity include concrete strength grade, steel bar specifications and usage and other related cost information. The directional link reflects the engineering related knowledge data between the engineering component data. For example, the column foundation can only be constructed after the pile foundation construction is completed, which constitutes the directional link from the pile foundation control entity to the column control entity.

[0079] The model implementation network element relationship is intended to represent the role and association of each element in the conversion to the engineering cost control network. Taking the pile foundation control entity as an example, its role in the entire conversion process is to serve as the starting part of the foundation project. The directional link relationship between it and the column control entity indicates the order of construction. This relationship will affect the logical order of cost control when converted to the engineering cost control network. Factors such as pile diameter and pile length in the control entity characteristics of the pile foundation control entity will be associated with the material consumption, construction difficulty and cost in cost control during conversion. Through a comprehensive analysis of all control entities, control entity characteristics and directional links, this model implementation network element relationship can be clarified, laying the foundation for subsequent conversion.

[0080] When determining the initial control entity in the engineering cost control network according to the model implementation network element relationship, it is necessary to base it on the starting position or logical starting point of the engineering component data in the entire cost control process. In the commercial building project, the control entity corresponding to the site leveling engineering component data can be used as the initial control entity. Because site leveling is the beginning of the entire construction project, in the cost control process, its completion is the prerequisite for the subsequent construction of many engineering components. The cost control of site leveling will affect the cost of a series of subsequent projects such as foundation engineering and main structure engineering. Logically speaking, the quality and cost control of site leveling work have a fundamental impact on the cost of the entire project. For example, factors such as the flatness of site leveling and the method of earthwork allocation are directly related to the difficulty and cost of subsequent foundation construction.

[0081] For the initial control entity, the corresponding component implementation guidance information is converted to generate the cost control related attributes of the converted initial control entity. The component implementation guidance information of the control entity corresponding to the site leveling engineering component data mainly involves cost information such as site cleaning, earth excavation and backfilling, and the use of site leveling machinery. When converting to cost control related attributes, it is necessary to consider the preliminary characteristics of the predicted control cost information expected from the start of engineering cost control for the single engineering component data of site leveling to the completion of engineering cost control for all engineering component data in the associated knowledge path. For example, the earth excavation volume of site leveling will affect the burial depth of the foundation in the subsequent foundation engineering. If the earth excavation volume is too large, it may be necessary to increase the material consumption of the foundation engineering to ensure the stability of the foundation. This potential cost increase needs to be reflected in the cost control related attributes of site leveling. By analyzing the relationship between the site leveling control entity and other related control entities (such as the subsequent foundation engineering control entity) in the model implementation network, the original simple component implementation guidance information is initially converted into the preliminary characteristics of the predicted control cost information that reflects the overall cost control concept.

[0082] Along the directional link, the cost control related attributes of the control entity associated with the initial control entity are expanded to generate the updated cost control related attributes of the control entity associated with the directional link of the initial control entity. Taking the pile foundation control entity in the foundation engineering associated with the site leveling control entity as an example, the cost control related attributes of the pile foundation were originally based on its own component implementation guidance information, such as the material cost of the pile, the construction process cost, etc. After considering the association with site leveling, since factors such as the flatness of the site leveling and the bearing capacity of the foundation after earth excavation will affect the construction difficulty and cost of the pile foundation, the cost control related attributes of the pile foundation need to be expanded. If the site leveling effect is not good, the pile foundation may need special treatment, such as increasing the pile length or improving the type of pile, which will lead to additional cost increases. These factors should be included in the updated cost control related attributes of the pile foundation.

[0083] According to the updated cost control related attributes of the control entity, the directional link is adjusted. Based on the adjusted directional link, all the control entity characteristics in the engineering cost control network are adjusted again, and all the control entities are connected according to the adjusted directional link, and each control entity is given the improved control entity characteristics to build a complete engineering cost control network. For example, after considering the update of the cost control related attributes of the pile foundation, the directional link between the pile foundation and the upper main structure column may need to be adjusted. The directional link that was originally based on the simple construction sequence relationship in the model implementation network now needs to take into account the impact of the change in the pile foundation cost on the main structure column cost. If the pile foundation cost increases, it may affect the design adjustment of the main structure column, such as the foundation connection method of the column or the reinforcement adjustment of the column, which requires that this cost association be reflected in the directional link. Based on the adjusted directional links, the control entity characteristics of the main structure columns are adjusted. For example, the impact of the column concrete strength grade and steel bar usage on the overall cost is re-evaluated. Similar adjustments are also made to other related control entities such as beams and slabs. Finally, all control entities are connected according to the adjusted directional links, and each control entity is given improved control entity characteristics, thereby constructing a complete engineering cost control network.

[0084] In a possible implementation, step S1222 may further include:

[0085] A mapping rule from the model implementation network to the engineering cost control network is defined, and the mapping rule is based on the attribute conversion of the control entity, the conversion of the control entity characteristics, and the conversion of the directional link. The control entity in the model implementation network is mapped to the control entity in the engineering cost control network, the control entity characteristics in the model implementation network are mapped to the control entity characteristics of the control entity in the engineering cost control network, and the directional link in the model implementation network is mapped to the directional link in the engineering cost control network.

[0086] Each control entity in the model implementation network is traversed, and each control entity in the model implementation network is converted into a corresponding control entity in the engineering cost control network according to the mapping rule. During the conversion process, the identification information of the control entity is retained.

[0087] For each control entity feature in the model implementation network, it is converted into a control entity feature of a corresponding control entity in the engineering cost control network according to the mapping rule.

[0088] The directional links in the model implementation network are traversed, and each directional link in the model implementation network is converted into a corresponding directional link in the engineering cost control network according to the mapping rule.

[0089] Check the converted engineering cost control network for legality, and output the engineering cost control network that passes the legality check, where the legality check includes checking the uniqueness of the control entity, whether the connection relationship of the directional link is correct, and whether the control entity characteristics are complete.

[0090] Based on the needs of engineering cost control, the engineering cost control network that has passed the legality check is optimized to generate an optimized engineering cost control network. The optimization process includes merging redundant control entities, simplifying directional link connection relationships, and adjusting the weights of control entity features.

[0091] The optimized engineering cost control network is hierarchically divided to generate different hierarchical structures, and a hierarchical model of the engineering cost control network is constructed according to the hierarchically divided engineering cost control network. The hierarchical model is used to display the structure and relationship of the engineering cost control network.

[0092] Based on the constructed hierarchical model, the engineering cost control network is refined and improved to generate a final engineering cost control network.

[0093] In this embodiment, the mapping rules are based on the conversion of the attributes of the control entity, the conversion of the control entity characteristics, and the conversion of the directional links. In the commercial building project, the pile foundation control entity in the model implementation network is mapped to the pile foundation control entity in the engineering cost control network, and the control entity characteristics (such as pile diameter, pile length and other related cost factors) of the pile foundation control entity in the model implementation network are mapped to the control entity characteristics of the pile foundation control entity in the engineering cost control network. The directional link from the pile foundation to the column foundation in the model implementation network is mapped to the corresponding directional link in the engineering cost control network.

[0094] Each control entity in the model implementation network is traversed, and each control entity in the model implementation network is converted into a corresponding control entity in the engineering cost control network according to the mapping rules. During the conversion process, the identification information of the control entity is retained. For example, when traversing to the beam control entity in the main structure, it is converted into the beam control entity in the engineering cost control network according to the mapping rules, and the identification information of the beam control entity in the model implementation network is retained, so as to accurately identify and associate related elements in the engineering cost control network.

[0095] For each control entity feature in the model implementation network, it is converted into the control entity feature of the corresponding control entity in the engineering cost control network according to the mapping rules. Taking the control entity feature of the distribution cabinet in the electromechanical equipment installation project as an example, the cost factors related to the component implementation guidance information such as the capacity and protection level of the distribution cabinet are converted into the control entity features of the distribution cabinet control entity in the engineering cost control network according to the mapping rules. These features will be closely related to the cost control of the distribution cabinet in the engineering cost control network.

[0096] The directional links in the model implementation network are traversed, and each directional link in the model implementation network is converted into a corresponding directional link in the engineering cost control network according to the mapping rules. For example, when the directional link from the column control entity to the beam control entity in the model implementation network is traversed to the directional link, it is converted into the corresponding directional link in the engineering cost control network according to the mapping rules. This conversion ensures that the logical relationship between the engineering component data in the engineering cost control network is correctly reflected.

[0097] Check the converted engineering cost control network for legality check, and output the engineering cost control network that has passed the legality check. In the engineering cost control network of the commercial building project, when checking the uniqueness of the control entity, ensure that each control entity (such as the control entity corresponding to each foundation pile, each column, etc.) is uniquely identified in the network, and there is no duplicate definition. Check whether the connection relationship of the directional link is correct, for example, whether the directional link from the foundation project to the main structure project accurately reflects the construction sequence and cost association relationship. Check whether the control entity characteristics are complete, such as whether the characteristics of the column control entity include all cost-related information such as concrete strength grade and steel bar usage. Only the engineering cost control network that has passed the legality check can be output for subsequent operations.

[0098] Based on the needs of engineering cost control, the engineering cost control network that has passed the legality check is optimized to generate an optimized engineering cost control network. In a commercial building project, there may be multiple similar foundation pile control entities. If they are similar in cost control, these redundant control entities can be merged to simplify the network structure. For some complex directional link connection relationships, such as the connection relationship between multiple electromechanical equipment, if there are some unnecessary cross links, they can be simplified. At the same time, according to the focus and actual needs of engineering cost control, the weight of the control entity characteristics is adjusted. For example, for the column control entity in the main structure project that has a greater impact on the overall cost, the weight of its control entity characteristics such as concrete strength grade and steel bar usage in cost control should be appropriately increased.

[0099] The optimized engineering cost control network is hierarchically divided to generate different hierarchical structures, and a hierarchical model of the engineering cost control network is constructed based on the hierarchically divided engineering cost control network. In commercial building projects, the division can be carried out according to the stages of the project and the hierarchical relationship of cost control. For example, the control entities related to the foundation engineering are divided into one level, the control entities related to the main structure engineering are divided into another level, and the control entities related to the electromechanical equipment installation engineering are divided into another level. The constructed hierarchical model can clearly show the structure and relationship of the engineering cost control network, such as the cost association relationship between the pile foundation control entity in the foundation engineering level and the column control entity in the main structure level is clear at a glance in the hierarchical model.

[0100] Based on the constructed hierarchical model, the engineering cost control network is refined and improved to generate the final engineering cost control network. On the basis of the hierarchical model, the cost relationship between the control entities within each level and between levels is further analyzed. For example, within the main structure engineering level, the detailed cost interaction relationship between the column, beam, and slab control entities is refined and analyzed, and the cost changes under different column, beam, and slab combinations are considered. At the same time, the connection relationship between different levels is improved, such as the precise association between the foundation engineering level and the main structure engineering level in cost control, so as to generate the final engineering cost control network, providing an accurate and comprehensive basis for the engineering cost control of commercial building projects.

[0101] In a possible implementation, the BIM engineering model also includes the implementation result of the first engineering component data of each engineering component data in the plurality of engineering component data. Step S140 includes:

[0102] Step S141 , implementing the plurality of engineering component data according to the engineering cost control sequence, and generating a second engineering component data implementation result for each of the plurality of engineering component data.

[0103] Step S142: if the implementation result of the first engineering component data and the implementation result of the second engineering component data of each of the multiple engineering component data match, then generate the engineering cost control management report for the BIM engineering model engineering cost control.

[0104] In this embodiment, the BIM engineering model of the commercial building project includes a plurality of engineering component data, and each engineering component data has its first engineering component data implementation result.

[0105] Taking the data of pile foundation engineering components in the foundation engineering of a commercial building as an example, according to the order of engineering cost control, the construction of the pile foundation begins in the early stage of the entire project. During the construction process, cost control is strictly carried out in accordance with the established cost control plan, which covers the material procurement cost control, construction process cost control and various resource allocation cost control during the construction process. For example, in terms of material procurement cost control, according to the design requirements and engineering budget, select the appropriate type of pile foundation (such as cast-in-place piles or prefabricated piles) and the corresponding material specifications. If it is a cast-in-place pile, the required amount of concrete and steel bars must be accurately calculated, and tendering and procurement must be carried out according to market prices to ensure that the material cost is within the budget. In terms of construction process cost control, according to the geological survey report, select the appropriate hole-making method (such as rotary drilling or impact drilling). Different hole-making methods have different costs, and it is necessary to weigh the relationship between construction efficiency, quality requirements and costs. In terms of resource allocation cost control during the construction process, reasonably arrange the rental time and use order of construction equipment (such as drilling rigs, concrete mixers, etc.) to avoid cost waste caused by idle equipment or excessive rental. Through these strict cost control measures, the second engineering component data implementation results of the pile foundation engineering component data were finally obtained.

[0106] Looking at the column engineering component data in the main structure, according to the order of engineering cost control, the construction of the column is carried out after the completion of the foundation engineering. In the cost control process of the column engineering component data, the first thing is to choose the concrete strength grade of the column, which should be determined according to the structural design calculation and the overall cost control requirements. If from the perspective of cost control, on the premise of meeting the structural safety, choosing the appropriate concrete strength grade can effectively control the cost. The steel bar configuration of the column is also an important cost control factor. The steel bar usage should be calculated according to the design load, and the impact of the steel bar specifications and models on the cost should be considered. In terms of the formwork installation of the column, choose the appropriate formwork type (such as wooden formwork, steel formwork or plastic formwork). The cost, turnover number and installation difficulty of different formworks are different, which need to be considered comprehensively. During the construction process, the labor costs of concrete pouring, steel bar binding and formwork installation are strictly controlled to ensure that the construction progress is coordinated with cost control. Finally, the implementation results of the second engineering component data of the column engineering component data are obtained.

[0107] For the curtain wall engineering component data of the building facade, when the cost control is carried out according to the engineering cost control order, the choice of curtain wall type (such as glass curtain wall, stone curtain wall or metal curtain wall) is the key cost control factor. Different types of curtain walls have great differences in material cost, installation process cost and maintenance cost. For example, for glass curtain walls, the impact of glass type (such as single-layer glass, double-layer insulating glass or triple-layer insulating glass), glass thickness, coating requirements, etc. on cost should be considered. For stone curtain walls, the impact of stone variety, specification, thickness and stone processing technology on cost should be considered. During the installation of the curtain wall, the labor cost of installation, the cost of auxiliary materials (such as sealants, pendants, etc.) and the rental cost of installation equipment (such as hanging baskets, cranes, etc.) are precisely controlled. Through these measures, the implementation results of the second engineering component data of the curtain wall engineering component data are obtained.

[0108] In terms of electromechanical equipment installation engineering, taking the power distribution cabinet engineering component data as an example, cost control is carried out according to the engineering cost control order. The selection of the power distribution cabinet should be determined according to the power load demand of the entire building, the design requirements of the power supply system and the cost control objectives. There are great differences in the cost of power distribution cabinets with different capacities and different protection levels. When purchasing power distribution cabinets, it is necessary to compare different brands and suppliers on the market and choose the most cost-effective products. The installation location of the power distribution cabinet will also affect the cost. Factors such as the laying path of the cable tray and the connection distance with other electrical equipment should be considered to reduce the cable usage and installation cost. During the installation process, the installation labor cost, grounding system cost and commissioning cost of the power distribution cabinet are strictly controlled to obtain the second engineering component data implementation result of the power distribution cabinet engineering component data.

[0109] After obtaining the implementation result of the second engineering component data of each engineering component data, a check for result matching is required. If the implementation result of the first engineering component data of each engineering component data in multiple engineering component data matches the implementation result of the second engineering component data, then a project cost control management report that passes the BIM engineering model engineering cost control is generated. For example, the implementation result of the first engineering component data of the pile foundation engineering component data includes the initial budget cost, expected material usage, expected construction period, etc., while the implementation result of the second engineering component data is the actual cost, actual material usage, actual construction period, etc. after actual construction. If the actual cost is within the budget cost range, the actual material usage is consistent with the expected material usage, and the actual construction period does not exceed the expected construction period, then it means that the implementation result of the first engineering component data of the pile foundation engineering component data matches the implementation result of the second engineering component data.

[0110] Similarly, for column engineering component data, the budget of concrete strength grade, steel bar usage, formwork type, etc. in the implementation results of the first engineering component data is compared with the actual situation in the implementation results of the second engineering component data. If they are consistent, the results of the column engineering component data match. For curtain wall engineering component data, the curtain wall type, material cost budget, installation process cost budget, etc. in the implementation results of the first engineering component data are compared with the actual situation in the implementation results of the second engineering component data. If they do not exceed the budget range and all indicators are consistent, then the results of the curtain wall engineering component data match. For distribution cabinet engineering component data, the distribution cabinet selection, procurement cost budget, installation location planning, etc. in the implementation results of the first engineering component data are checked with the actual situation in the implementation results of the second engineering component data. If they are consistent, then the results of the distribution cabinet engineering component data match.

[0111] When the implementation results of the first engineering component data of all engineering component data match the implementation results of the second engineering component data, the generated engineering cost control management report records in detail the engineering cost control of the entire BIM engineering model. The report content includes the original budget, actual cost, cost savings or overspending analysis of each engineering component data. For example, for the pile foundation engineering component data, if there is cost savings, it may be because the construction process is optimized during the construction process to reduce material waste; if there is cost overspending, it may be because the geological conditions change and the construction difficulty increases, and additional treatment measures are required. For column engineering component data, cost changes may be related to factors such as concrete price fluctuations and adjustments to the amount of steel bars. Cost changes in curtain wall engineering component data may be related to factors such as material price fluctuations and installation process adjustments. Cost changes in distribution cabinet engineering component data may be related to factors such as adjustments to the selection of distribution cabinets and market price fluctuations. This engineering cost control management report accurately reflects the implementation of the BIM engineering model in the engineering cost control process and provides an important basis for project cost management.
