Description

Technical Field

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

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

[0003] However, existing BIM-based project cost control methods still have many deficiencies. On the one hand, these methods often only focus on the cost control of individual engineering components, while ignoring the relevance and mutual influence between components, resulting in limited control effects. On the other hand, there is a lack of intelligent cost control guidance information, and it is unable to dynamically adjust control strategies 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 relevance between engineering components, provide intelligent cost control guidance information, and automatically generate a systematic and accurate project cost control management report to overcome the deficiencies of the existing technology and improve the project cost control level and management efficiency of construction projects.

[0012] Figure 1 is a schematic execution flow diagram of an engineering cost control management report generation method applied to construction projects provided by an embodiment of the present invention.

[0013] Figure 2 is a schematic hardware architecture diagram of an engineering cost control management report generation system applied to construction projects provided by an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The present invention will be specifically described below in conjunction with the accompanying drawings of the specification. Figure 1It is a schematic flowchart of a method for generating a project cost control and management report applied to construction projects according to an embodiment of the present invention. The method for generating a project cost control and management report applied to construction projects will be introduced in detail below.

[0015] Step S110, obtain the BIM engineering model to be subject to project cost control uploaded by the BIM model management system. The BIM engineering model includes engineering component data of multiple components to be subject to project cost control.

[0016] In this embodiment, for the 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, and parking lots. 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 project cost, it is necessary to upload this BIM engineering model to a specific project cost control system.

[0017] In this BIM engineering model, the engineering component data of multiple components includes various parts of the building. For example, the engineering component data of the foundation structure part includes relevant data of various types of foundation piles (such as cast-in-place piles, precast piles, etc.), and these data cover information such as the size, material, and construction technology of the piles. These information are crucial for project cost control. There is also the engineering component data of the main building structure, such as the relevant data of concrete columns, beams, and slabs, including their cross-sectional dimensions, concrete strength grades, and steel bar configurations. For the exterior facade part of the building, the engineering component data of the curtain wall project is also included, such as the type of curtain wall (glass curtain wall, stone curtain wall, etc.), the structure of the curtain wall, and the material specifications used. In addition, the engineering component data of the installation project of mechanical and electrical equipment inside the building is also in this model, including the relevant data of power distribution cabinets, cable trays, 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. They each have different characteristics and cost influencing factors and are the basis for subsequent project cost control. When the BIM model management system uploads this BIM engineering model containing rich engineering component data, the project cost control system obtains this BIM engineering model to be subject to project cost control.

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

[0019] Continuing with the BIM engineering model of the commercial building mentioned above, the acquisition of cost control guidance information has a clear source and content. For the engineering association knowledge data, taking the structural part of the building as an example, there are close engineering association knowledge data between the foundation structure and the main structure. The stability of the foundation structure directly affects the safety and construction technology of the main structure. This association relationship 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 the cost control knowledge data, assume that the cost engineering control is started from the foundation piles (engineering component data). If the cast-in-place pile construction technology is used for the foundation piles, its cost control knowledge data will consider the predicted control cost information expected for all the engineering component data in the association knowledge path from the start of cast-in-place pile construction to the completion of cost engineering control for the subsequent associated engineering component data (such as the construction of the foundation cap after the completion of cast-in-place pile construction and then to the construction of the upper main structure columns, etc.). This predicted control cost information includes material costs, labor costs, mechanical equipment rental costs, and possible risk costs, etc.

[0020] Then look at the association between the engineering component data of the mechanical and electrical equipment installation and the engineering component data of the building main structure. In terms of the engineering association knowledge data, the position and size of the floor reserved holes in the main structure must match the pipeline laying path in the mechanical and electrical equipment installation, otherwise additional construction costs will be incurred. For the distribution cabinet, an engineering component data in the mechanical and electrical equipment installation, its cost control knowledge data will consider the predicted control cost information expected for all the engineering component data in the association knowledge path from the start of distribution cabinet installation to the completion of cost engineering control for the associated cable tray laying, lighting equipment wiring, etc. This may involve the procurement cost of the distribution cabinet itself, the installation labor cost, and the cost changes caused by the influence of the installation position of the distribution cabinet on the subsequent cable tray and lighting equipment installation (such as the additional material and labor costs for the cable tray to bypass the distribution cabinet, etc.). The cost control guidance information can be summarized by an expert team with rich experience in building project cost based on the data and experience of previous similar projects, and then these information are associated with the engineering component data in the BIM engineering model and provided to the project cost control system, or it can be the result obtained by analyzing and mining a large amount of historical data of building projects.

[0021] Step S130, based on the project-related knowledge data and the cost control knowledge data of each project component data, arrange the multiple project component data to generate the project cost control order of the multiple project component data.

[0022] Still taking the commercial building project as an example, arrange the project component data based on the project-related knowledge data and the cost control knowledge data. First, based on the project-related knowledge data, determine the first project component data belonging to the first arrangement order level. For this commercial building project, some independent foundation components in the foundation project may be the first project component data because these independent foundation components are relatively independent in the entire building structure system and there is no directly related pre-project component data. For example, some independent foundations are directly located on the original land foundation and can be constructed without relying on other foundation structure components. Then, based on the comparison results between the cost control knowledge data of each independent foundation component, determine their project cost control order under the first arrangement order level. Suppose there is an independent foundation component A, due to its good geological conditions, relatively low construction difficulty, and relatively low predicted control cost information, such as short material transportation distance and no need for special foundation treatment technology, while another independent foundation component B is located in an area with a high groundwater level and requires dewatering treatment and special foundation reinforcement, and its predicted control cost information is relatively high. Therefore, under the first arrangement order level, the project cost control order of component A may be prior to that of component B.

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

[0024] Further determine the data of the subsequent engineering components belonging to the subsequent arrangement order level, such as column components in the main structure. The column components are engineering-related to the foundation cap, and the cost control knowledge data of the column components need to consider the predicted control cost information from the start of the construction of the column components to the completion of the construction of related components such as beams and slabs. If the height of column component E is relatively high and high-strength concrete and more steel bars are required for reinforcement, its predicted control cost is relatively 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 prior to that of column component E. Through such step-by-step analysis and comparison, the data of multiple engineering components in the entire BIM engineering model are arranged, and finally the engineering cost control order is generated.

[0025] Step S140, in the process of engineering cost control of the BIM engineering model, according to the engineering cost control order, perform engineering cost control on the data of the multiple engineering components, generate an engineering cost control management report of the BIM engineering model, and send the engineering cost control management report to the BIM model management system.

[0026] Perform engineering cost control according to the engineering cost control order generated for the above commercial building project. First, start the control from the data of the engineering components ranked in the front, such as starting from the independent foundation component A. During the construction process, strictly monitor and manage the costs such as material procurement, labor use, and mechanical equipment leasing in accordance with the budget and cost control requirements. Assume that in the construction of the independent foundation component A, through effective cost control measures, the material procurement is carried out according to the predetermined price and quality standards, the labor hours do not exceed the budget, and the leasing time of the mechanical equipment is also within a reasonable range. Then, the implementation result of the second engineering component data of the independent foundation component A is obtained. Then, perform engineering cost control on the foundation cap D in order, and also monitor its various costs to ensure that the construction is carried out within the predicted control cost information estimated by its cost control knowledge data.

[0027] During the process of controlling the project cost of the entire BIM engineering model, such control operations are sequentially performed on the data of each engineering component. Assume that the implementation results of the first engineering component data and the second engineering component data of all engineering component data are both matched, that is, the results of each engineering component data in the actual project cost control process are consistent with the expected cost control knowledge data. For example, the costs of components such as beams and slabs in the main structure and various equipment and pipeline components in the installation of mechanical and electrical equipment are all within the predicted range during the actual construction process. Then a project cost control management report indicating the passing of the project cost control for this BIM engineering model is generated. This report details the cost control situation of each engineering component data, including the original budget, actual expenditure, and analysis of the reasons for cost savings or overruns, etc. 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 strategies for subsequent similar projects, etc.

[0028] Based on the above steps, the embodiment of the present application realizes the refined management and control of the data of multiple engineering components in the construction project by obtaining the BIM engineering model and its cost control guiding information uploaded by the BIM model management system. This method not only considers the engineering correlation knowledge data among the engineering component data, but also deeply excavates the cost control knowledge data of each engineering component data under the correlation 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 project cost control order of multiple engineering component data, ensuring the scientificity and rationality of the project cost control. During the process of controlling the project cost 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 sequence. The finally generated project cost control management report 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 manner, step S130 includes:

[0030] Step S131, based on the engineering correlation knowledge data, determine the first engineering component data belonging to the first ranking order level among the multiple engineering component data. The first engineering component data represents the engineering component data without associated engineering component data among the multiple engineering component data.

[0031] Step S132, based on the comparison results among the cost control knowledge data of each first engineering component data, determine the project cost control order of each first engineering component data at the first ranking order level.

[0032] Step S133: Based on the project correlation knowledge data, determine the second project component data belonging to the second ranking order level among the multiple project component data. The second project component data represents the project component data among the multiple project component data that is associated with the first project component data.

[0033] Step S134: Based on the comparison results among the cost control knowledge data of each of the second project component data, determine the project cost control order of each of the second project component data at the second ranking order level.

[0034] Step S135: Further determine the subsequent project component data belonging to the subsequent ranking order level, and determine the project cost control order of each of the subsequent project component data at the subsequent ranking order level. The project cost control order of the first ranking order level precedes that of the second ranking order level.

[0035] In a possible implementation manner, the cost control guidance information is extracted from a project cost control network. The project cost control network includes control entities and direction links. The control entities in the project cost control network are used to represent the project component data in the BIM project model. The control entity features of the control entities in the project cost control network are used to represent the cost control knowledge data of the project component data in the BIM project model. The direction links in the project cost control network are used to represent the project correlation knowledge data among the project component data in the BIM project model.

[0036] The direction links connected to the target control entity in the project cost control network include at least one of the following: input link and output link. The target control entity has an input link, which 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 target control entity has an output link, which is used to represent that the target control entity is associated with a specified control entity, and the specified 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 one of the control entities in the project cost control network.

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

[0038] In this embodiment, taking the previously mentioned commercial building project as an example, first, based on the project-related knowledge data, the first project component data belonging to the first ranking order level needs to be determined from multiple project component data. For the BIM project model of the commercial building project, among numerous project component data, the site leveling project component data can be regarded as the first project component data. Site leveling is the starting work of the construction project. In the entire project component data system, it has no associated project component data as a prerequisite, that is, it does not need to rely on the completion of other project components to proceed. Its cost control knowledge data includes relevant cost information such as site cleaning, earthwork excavation and backfilling, and the use of site leveling machinery.

[0039] Next, based on the comparison results among the cost control knowledge data of each first project component data, the project cost control order of each first project component data at the first ranking order level is determined. Suppose that in addition to site leveling, the temporary facility construction project component data also belongs to the category of the first project component data. The cost control knowledge data of site leveling shows that its main costs are concentrated in the earthwork project. Since the site geological conditions are good, the earthwork excavation volume is relatively small, the machinery and equipment rental cost is low, and the estimated total cost is relatively low. For the temporary facility construction project component data, since it needs to meet the needs of office, accommodation, material stacking, etc. during the entire project construction period, with a large scale, it is necessary to purchase more temporary building materials and carry out site planning and facility layout, and its cost control knowledge data shows that the estimated total cost is relatively high. Therefore, at the first ranking order level, the project cost control order of site leveling precedes that of temporary facility construction.

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

[0041] Based on the comparison results among the cost control knowledge data of each second engineering component data, determine the project cost control order of each second engineering component data under the second ranking order level. Suppose there are two independent footings. The designed bearing capacity of independent footing A is relatively low, its size is small, the required amount of concrete and steel is relatively less, and the construction difficulty is also relatively low. Therefore, the cost control knowledge data shows that its estimated total cost is relatively low. Independent footing B has a high bearing capacity requirement, a large size and is located in an area with a high groundwater level, and requires special waterproofing and reinforcement measures. The cost control knowledge data shows that its estimated total cost is relatively high. Therefore, under the second ranking order level, the project cost control order of independent footing A precedes that of independent footing B.

[0042] Further determine the subsequent engineering component data belonging to the subsequent ranking order level and determine its project cost control order under the corresponding level. The engineering component data of the main structure after the independent footing, such as the column engineering component data, belongs to the subsequent ranking order level. The column engineering component data is associated with the independent footing engineering component data. The cost control knowledge data of the column includes the cost of column body concrete pouring, the cost of steel bar configuration in the column, and the cost of column formwork installation, etc. Considering columns in different positions, for example, columns at the bottom layer may require a larger cross-sectional size and more steel bars due to bearing greater loads, and the cost control knowledge data shows that their estimated costs are relatively high, while columns in the upper part of the building have relatively smaller loads and lower costs. Therefore, under this subsequent ranking order level, the project cost control order of columns in the upper part of the building precedes that of columns at the bottom layer.

[0043] Regarding the extraction of cost control guidance information from the project cost control network, take the construction of a commercial building project to build a project cost control network as an example. The control entities in the project cost control network are used to represent the engineering component data in the BIM engineering model. For example, the engineering component data of the pile foundation in the foundation project is represented as a control entity in the project cost control network. The control entity features of the control entities in the project cost control network are used to represent the cost control knowledge data of the engineering component data in the BIM engineering model. For the control entity of the pile foundation, its control entity features include cost-related information affected by factors such as the type of pile (such as friction pile or end-bearing pile), pile length, pile diameter, etc., such as the material costs and construction process costs of different pile types. The directional links in the project cost control network are used to represent the engineering association knowledge data among the engineering component data in the BIM engineering model. For example, there is a directional link between the pile foundation and the bearing platform, and this directional link represents their engineering association relationship, that is, the bearing platform construction is carried out after the pile foundation construction is completed.

[0044] The directional links connected to the target control entity in the project 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 project 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. There is an input link from the beam to the column, which means the beam is associated with the column, and the construction of the beam requires the completion of the column construction as a prerequisite. That is, this control entity of the beam is connected to the column based on the input link of the target control entity of the column. At the same time, the beam has an output link to the control entity corresponding to the subsequent slab engineering component data, which means the beam is associated with the slab, and the construction of the slab requires the completion of the beam construction as a prerequisite. This designated control entity of the slab is connected to the beam based on the output link of the target control entity of the beam.

[0045] For the first engineering component data representing the engineering component data characterized by the first control entity in the project cost control network, and the case where the first control entity has an output link but no input link. Still taking the site leveling engineering component data as an example, the first control entity corresponding to it in the project 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 output to the control entities corresponding to the subsequent engineering component data such as the foundation project, providing construction site preparation for the subsequent projects.

[0046] For the second engineering component data representing the engineering component data characterized by the second control entity in the project cost control network, and the case where the second control entity is connected to the output link of the first control entity. Such as the second control entity corresponding to the independent foundation engineering component data, which is connected to the output link of the first control entity corresponding to the site leveling engineering component data. This means that the construction of the independent foundation is carried out after the site leveling is completed. Through this link relationship in the project cost control network, the engineering association relationship between the engineering component data and the logical sequence of cost control are accurately reflected.

[0047] In a possible implementation manner, 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] Wherein, the model implementation guidance information includes the engineering association knowledge data, and the component implementation guidance information of each engineering component data. The component implementation guidance information of any engineering component data characterizes the control cost information for implementing the corresponding engineering component data.

[0051] In a possible implementation manner, 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 project 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 a commercial building project, when the BIM model management system manages the BIM engineering model of the entire commercial building, it may have pre-organized the cost control guidance information based on the experience data of previous similar projects, industry standards, and the specific requirements of this project, etc. These cost control guidance information cover the engineering association knowledge data between engineering component data. For example, the association between the basic 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 of the main structure columns; it also includes the cost control knowledge data of each engineering component data. For example, for the pile foundation in the basic engineering, its cost control knowledge data includes the pile type selection (such as selecting different types of piles according to geological conditions), the impact of the pile construction technology on the cost, etc. The BIM model management system directly uploads these comprehensive and organized cost control guidance information, and after the project cost control system obtains this information, it can perform subsequent project cost control operations.

[0056] Another way is to obtain the model implementation guidance information uploaded by the BIM model management system and then generate the cost control guidance information based on this. For a commercial building project, the engineering association knowledge data in the model implementation guidance information describes the construction sequence and interdependence relationship between engineering components. For example, the engineering association knowledge data between the mechanical and electrical equipment installation engineering component data and the building main structure engineering component data indicates that the reserved holes and embedded parts in the main structure must be set according to the requirements of the mechanical and electrical equipment installation, because the installation path of the mechanical and electrical equipment depends on these settings of the main structure. The component implementation guidance information of each engineering component data represents the control cost information for 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, the rental cost of mechanical equipment required for curtain wall construction, etc.

[0057] When constructing a model implementation network based on model implementation guidance information, take the 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. For example, the raft foundation engineering component data in the foundation project is used 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 control entity of the raft foundation, 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 construction of the raft foundation is completed.

[0058] The process of converting the model implementation network into a project cost control network is still illustrated by taking the commercial building project as an example. In the model implementation network, the control entity corresponds to the engineering component data, the control entity characteristics correspond 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 relationships of these elements included in the model implementation network, the model implementation network element relationships are generated. This relationship clarifies the roles and association methods of each element in the conversion into the project cost control network. For example, determine the initial control entity in the project cost control network according to 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 the subsequent projects). For the initial control entity, convert the corresponding component implementation guidance information. For example, the component implementation guidance information of the raft foundation was originally based on the simple construction implementation cost. After conversion, it should reflect the preliminary characteristics of the predicted control cost information expected to complete the project cost control for all the engineering component data (such as from the raft foundation to the upper structure columns, beams, plates, etc.) in the knowledge path from the activation of the project cost control of the raft foundation. This may require comprehensively considering the impact of the raft foundation construction on the subsequent projects, such as the potential costs caused by the construction accuracy of the raft foundation on the upper structure construction. Along the directional link, expand the cost control-related attributes of the control entities associated with the initial control entity. For example, expand the cost control-related attributes of the main structure column control entity to generate the updated cost control-related attributes of the control entity that has a directional link association with the initial control entity. Finally, according to the updated cost control-related attributes of the control entity, adjust the directional link. Based on the adjusted directional link, adjust all the control entity characteristics in the project cost control network again, then connect all the control entities according to the adjusted directional link, and endow each control entity with the improved control entity characteristics to construct a complete project cost control network.

[0059] When extracting cost control guidance information from the project cost control network, in the constructed project cost control network, control entities are used to represent the engineering component data in the BIM engineering model, the control entity features of the control entities are used to represent the cost control knowledge data of the engineering component data in the BIM engineering model, and the directional links are 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, providing a basis for subsequent project cost control work.

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

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

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

[0064] Among them, the directional links connected to the target control entity in the model implementation network include at least one of the following: input link and output link. The target control entity has an input link 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 target control entity has an output link to represent that the target control entity is associated with the 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 one of the control entities in the model implementation network.

[0065] In this embodiment, taking a 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 foundation component data in the foundation engineering, such as pile foundation (including different types of pile foundation component data like cast-in-place pile, precast pile, etc.), raft foundation component data, etc., are all regarded as control entities in the model implementation network. The column component data, beam component data, and slab component data in the main structure are also control entities. Additionally, the curtain wall component data on the building facade, the distribution cabinet component data, cable tray component data in the internal mechanical and electrical equipment installation project, and the pipe component data in the water supply and drainage system, etc., all these engineering component data respectively correspond 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 feature 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 materials such as concrete and steel bars, while precast piles have their specific precast component materials. Information such as the procurement cost and transportation cost of these materials belongs to the component implementation guidance information and becomes the control entity feature of the pile foundation control entity in the model implementation network. In terms of the construction technology of the pile foundation, for example, the different construction costs and construction efficiencies corresponding to the hole-forming methods (such as rotary drilling, impact drilling, etc.) of cast-in-place piles also serve as the control entity features 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 formwork type of the column in its component implementation guidance information all become the control entity features of the column control entity in the model implementation network. For the curtain wall component data, the component implementation guidance information such as the material cost determined by the type of the curtain wall (glass curtain wall, stone curtain wall, etc.), the labor cost corresponding to the installation technology, and the cost of auxiliary materials required are all transformed into the control entity features of the curtain wall control entity in the model implementation network.

[0067] Then, the engineering association knowledge data among 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. Taking the relationship between the foundation engineering and the superstructure engineering as an example, the construction of the columns of the superstructure can only be carried out after the pile foundation or raft foundation is completed. This kind of engineering association knowledge data is reflected in the model implementation network as the directional link from the control entity corresponding to the foundation engineering component data (pile foundation or raft foundation control entity) to the control entity corresponding to the superstructure column component data. For the interior of the superstructure, the construction of the beams is carried out after the columns are completed, and the construction of the slabs is carried out after the beams are completed. This series of engineering association knowledge data is respectively reflected in the model implementation network as the directional links from the column control entity to the beam control entity and from the beam control entity to the slab control entity. Looking at the relationship between the installation engineering of mechanical and electrical equipment and the superstructure engineering of the building, holes need to be reserved in the floor slabs of the superstructure to meet the laying requirements of cable trays and pipelines in the installation engineering of mechanical and electrical equipment. This kind of associated knowledge data is reflected in the model implementation network as the directional links between the floor slab control entity of the superstructure 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, and 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, there is an input link from the beam 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 characterizes the sequence relationship in the construction order, that is, the completion of the column construction is a prerequisite for the beam construction. Starting from the control entity of the beam, when considering the control entity corresponding to the slab component data, there is an output link from the beam to the slab. This indicates that the target control entity of the beam is associated with the specified control entity of the slab, and the specified control entity of the slab is connected to the beam based on the output link of the beam, meaning that the completion of the beam construction is a prerequisite for the slab construction.

[0069] Taking the control entity corresponding to the distribution cabinet component data in the mechanical and electrical equipment installation project as an example, when considering the control entity corresponding to the power supply line laying project component data, the distribution cabinet has an output link to the power supply line laying. This means that the target control entity of the distribution cabinet is associated with the specified control entity of the power supply line laying. The specified 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 after the distribution cabinet is installed. When considering the power supply source (such as the control entity corresponding to the relevant project component data of the substation, etc.), the distribution cabinet has an input link to the power supply source. This means that the target control entity of the distribution cabinet is associated with the other control entity of the power supply source. 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 properly.

[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 inlet pipe project component data, the water tank has an input link to the inlet pipe. This means that the target control entity of the water tank is associated with the other control entity of the inlet pipe. The other control entity of the inlet pipe is connected to the water tank based on the input link of the water tank because the water tank needs the inlet pipe to provide water source. When considering the control entity corresponding to the outlet pipe project component data, the water tank has an output link to the outlet pipe. This indicates that the target control entity of the water tank is associated with the specified control entity of the outlet pipe. The specified control entity of the outlet pipe 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 outlet pipe. By mapping the relationships between project component data to the directional links between control entities in the model implementation network in such a detailed manner, a model implementation network that reflects the engineering implementation logic of the commercial building project can be accurately constructed, laying a solid foundation for subsequent conversion into a project cost control network.

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

[0072] Based on the control entities, control entity features, and directional links included in the model implementation network, generate model implementation network element relationships, where the control entities correspond to project component data, the control entity features correspond to component implementation guidance information, the directional links correspond to the engineering association knowledge data between project component data, and the model implementation network element relationships are used to represent the roles and association methods of each element in the conversion into the project cost control network.

[0073] According to the model implementation network element relationships, determine the initial control entities in the project cost control network. The determination of the initial control entities is based on the starting position or logical starting point of the project component data in the entire cost control process.

[0074] For the initial control entity, the guidance information for the corresponding component is transformed to generate the cost control related attributes of the transformed initial control entity. The cost control related attributes reflect the preliminary characteristics of the predicted control cost information expected from enabling project cost control for individual engineering component data to completing project cost control for all engineering component data in the associated knowledge path. Among them, by analyzing the relationship between the initial control entity and other relevant control entities in the model implementation network, the component implementation guidance information is initially transformed into the preliminary characteristics of the predicted control cost information reflecting the overall cost control concept.

[0075] Along the direction link, the cost control related attributes of the control entity associated with the initial control entity are extended to generate the updated cost control related attributes of the control entity with a direction link association with the initial control entity.

[0076] Based on the updated cost control related attributes of the control entity, the direction link is adjusted. Based on the adjusted direction link, after readjusting all the control entity characteristics in the project cost control network, all the control entities are connected according to the adjusted direction link, and each control entity is given the improved control entity characteristics to construct a complete project cost control network.

[0077] In this embodiment, taking the commercial building project as an example, a detailed scenario example is given for the process of transforming the model implementation network into a project cost control network.

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

[0079] The model implementation network element relationship aims to represent the roles and associated ways of each element in the conversion to the project 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 sequence of construction. When this relationship is converted to the project cost control network, it will affect the logical sequence of cost control. Factors such as pile diameter and pile length in the control entity characteristics of the pile foundation control entity will be associated with material consumption, construction difficulty, and cost in cost control during conversion. Through the comprehensive analysis of all control entities, control entity characteristics, and directional links, this model implementation network element relationship can be clarified, laying a foundation for subsequent conversion.

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

[0081] For the initial control entity, convert the component implementation guidance information corresponding to it 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 preparation engineering component data mainly involves cost information such as site cleaning, earthwork excavation and backfilling, and the use of site preparation 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 project cost control from this single engineering component data of site preparation to the completion of project cost control for all engineering component data in the associated knowledge path. For example, the earthwork excavation volume of site preparation will affect the buried depth of the foundation in subsequent foundation projects. If the earthwork excavation volume is too large, it may be necessary to increase the material consumption of the foundation project to ensure the stability of the foundation, and this potential cost increase needs to be reflected in the cost control-related attributes of site preparation. By analyzing the relationship between the site preparation control entity and other relevant control entities (such as subsequent foundation project control entities) in the model implementation network, the originally simple component implementation guidance information is initially converted into the preliminary characteristics of the predicted control cost information reflecting the overall cost control concept.

[0082] Along the direction link, extend the cost control related attributes of the control entity associated with the initial control entity to generate the updated cost control related attributes of the control entity that has a directional link association with the initial control entity. Taking the pile foundation control entity in the foundation project 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 site leveling and the bearing capacity of the foundation after earth excavation will affect the construction difficulty and cost of the pile foundation, it is necessary to extend the cost control related attributes of the pile foundation. If the site leveling effect is not good, special treatment may be required for the pile foundation, such as increasing the pile length or improving the pile type, which will result in additional cost increases. These factors should be incorporated into the updated cost control related attributes of the pile foundation.

[0083] According to the updated cost control related attributes of the control entity, adjust the direction link. Based on the adjusted direction link, after adjusting all the control entity features in the project cost control network again, connect all the control entities according to the adjusted direction link, and endow each control entity with the improved control entity features to construct a complete project cost control network. For example, after considering the update of the cost control related attributes of the pile foundation, the direction link between the pile foundation and the main structure column of the upper part may need to be adjusted. The original direction link based on the simple construction sequence relationship in the model implementation network now needs to consider the impact of the cost change of the pile foundation on the cost of the main structure column. If the cost of the pile foundation increases, it may affect the adjustment of the design scheme of the main structure column, such as the foundation connection method of the column or the adjustment of the steel reinforcement of the column. This requires reflecting this cost association in the direction link. Based on the adjusted direction link, adjust the control entity features of the main structure column. For example, re-evaluate the impact of the concrete strength grade and steel usage of the column on the overall cost, and at the same time make similar adjustments to other related control entities such as beams and slabs. Finally, connect all the control entities according to the adjusted direction link and endow each control entity with the improved control entity features to construct a complete project cost control network.

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

[0085] Define the mapping rules from the model implementation network to the project cost control network, which are based on the conversion of control entity attributes, the conversion of control entity features, and the conversion of direction links. Among them, the control entities in the model implementation network are mapped to the control entities in the project cost control network, the control entity features in the model implementation network are mapped to the control entity features of the control entities in the project cost control network, and the direction links in the model implementation network are mapped to the direction links in the project cost control network.

[0086] Traverse each control entity in the model implementation network, and according to the mapping rule, convert each control entity in the model implementation network into the corresponding control entity in the project cost control network. During the conversion process, the identification information of the control entity is retained.

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

[0088] Traverse the directional links in the model implementation network, and according to the mapping rule, convert each directional link in the model implementation network into the corresponding directional link in the project cost control network.

[0089] Check the legality of the converted project cost control network, and output the project cost control network that passes the legality check. Among them, 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 feature is complete.

[0090] Based on the requirements of project cost control, optimize the project cost control network that passes the legality check to generate an optimized project cost control network. The optimization process includes merging redundant control entities, simplifying the connection relationship of directional links, and adjusting the weights of control entity features.

[0091] Perform hierarchical partitioning on the optimized project cost control network to generate different hierarchical structures, and construct a hierarchical model of the project cost control network according to the hierarchically partitioned project cost control network. The hierarchical model is used to display the structure and relationship of the project cost control network.

[0092] Based on the constructed hierarchical model, refine and improve the project cost control network to generate the final project cost control network.

[0093] In this embodiment, the mapping rule is based on the conversion of control entity attributes, the conversion of control entity features, and the conversion of directional links. In a commercial building project, the pile foundation control entity in the model implementation network is mapped to the pile foundation control entity in the project cost control network, and the control entity features (such as relevant cost factors such as pile diameter and pile length) of the pile foundation control entity in the model implementation network are mapped to the control entity features of the pile foundation control entity in the project 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 project cost control network.

[0094] Traverse each control entity in the model implementation network. According to the mapping rules, convert each control entity in the model implementation network into the corresponding control entity in the project cost control network, and preserve the identification information of the control entity during the conversion process. For example, when traversing the beam control entity in the main structure, convert it into the beam control entity in the project cost control network according to the mapping rules, and preserve the identification information of the beam control entity in the model implementation network to accurately identify and associate relevant elements in the project cost control network.

[0095] For each control entity feature in the model implementation network, convert it into the control entity feature of the corresponding control entity in the project cost control network according to the mapping rules. Taking the control entity features of the distribution cabinet in the mechanical and electrical equipment installation project as an example, cost factors related to the implementation guidance information of components 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 project cost control network according to the mapping rules, and these features will be closely related to the cost control of the distribution cabinet in the project cost control network.

[0096] Traverse the directional links in the model implementation network. According to the mapping rules, convert each directional link in the model implementation network into the corresponding directional link in the project cost control network. For example, for the directional link from the column control entity to the beam control entity in the model implementation network, when traversing this directional link, convert it into the corresponding directional link in the project cost control network according to the mapping rules. This conversion ensures that the logical relationship between the engineering component data in the project cost control network is correctly reflected.

[0097] Check the legality of the converted project cost control network and output the project cost control network that passes the legality check. In the project cost control network of a commercial building project, when checking the uniqueness of control entities, 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 situation of duplicate definition. Check whether the connection relationship of the directional links is correct. For example, whether the directional link from the foundation project to the main structure project accurately reflects the construction sequence and cost correlation relationship. Check whether the control entity features are complete. For example, whether the features of the column control entity include all cost-related information such as concrete strength grade and steel usage. Only the project cost control network that passes the legality check can be output for subsequent operations.

[0098] Based on the requirements of project cost control, optimize the project cost control network that has passed the legality check to generate an optimized project cost control network. In a commercial building project, there may be multiple similar foundation pile control entities. If they are similar in terms of 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 relationships between multiple mechanical and electrical equipment, if there are some unnecessary cross-links, they can be simplified. At the same time, adjust the weights of the control entity features according to the key points and actual requirements of project cost control. For example, for the column control entity in the main structure project that has a greater impact on the overall cost, appropriately increase the weights of control entity features such as its concrete strength grade and steel usage in cost control.

[0099] Hierarchically partition the optimized project cost control network to generate different hierarchical structures, and based on the hierarchically partitioned project cost control network, construct a hierarchical model of the project cost control network. In a commercial building project, it can be partitioned according to the project phases and the hierarchical relationship of cost control. For example, partition the control entities related to the foundation project into one level, the control entities related to the main structure project into another level, and the control entities related to the mechanical and electrical equipment installation project into yet another level. The constructed hierarchical model can clearly display the structure and relationships of the project cost control network. For example, the cost correlation relationship between the pile foundation control entity in the foundation project level and the column control entity in the main structure level is clearly visible in the hierarchical model.

[0100] Based on the constructed hierarchical model, refine and improve the project cost control network to generate the final project cost control network. On the basis of the hierarchical model, further analyze the cost relationships between control entities within and between each level. For example, within the main structure project level, conduct a detailed refinement analysis of the cost interaction relationships between column, beam, and slab control entities, considering the cost changes under different combinations of columns, beams, and slabs. At the same time, improve the connection relationships between different levels, such as the precise correlation in cost control between the foundation project level and the main structure project level, so as to generate the final project cost control network, providing an accurate and comprehensive basis for the project cost control of the commercial building project.

[0101] In a possible implementation manner, the BIM engineering model further includes the implementation results of the first engineering component data for each of the multiple engineering component data. Step S140 includes:

[0102] Step S141, implement the multiple engineering component data according to the project cost control order to generate the implementation results of the second engineering component data for each of the multiple engineering component data.

[0103] In step S142, if the implementation results of the first engineering component data of each engineering component data among the multiple engineering component data match the implementation results of the second engineering component data, a project cost control management report indicating that the BIM project model has passed the project cost control is generated.

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

[0105] Taking the pile foundation engineering component data in the foundation project of a commercial building as an example, in accordance with the order of project 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 aspects such as the cost control of pile foundation material procurement, construction technology cost control, and various resource allocation cost controls during the construction process. For example, in terms of cost control of material procurement, according to the design requirements and project budget, the appropriate type of pile foundation (such as cast-in-place pile or precast pile) and the corresponding material specifications are selected. If it is a cast-in-place pile, the required amount of concrete and steel bars is accurately calculated, and tender procurement is carried out based on the market price to ensure that the material cost is within the budget. In terms of construction technology cost control, the appropriate hole-forming method (such as rotary drilling or percussion drilling) is selected according to the geological exploration report. Different hole-forming methods have different costs, and the relationship between construction efficiency, quality requirements, and cost needs to be weighed. In terms of cost control of resource allocation during the construction process, the rental time and usage sequence of construction equipment (such as drilling rigs, concrete mixers, etc.) are reasonably arranged to avoid cost waste caused by equipment idleness or over-rental. Through these strict cost control measures, the implementation result of the second engineering component data of the pile foundation engineering component data is finally obtained.

[0106] Looking at the column engineering component data in the main structure again, in accordance with the order of project cost control, the construction of the column is carried out after the completion of the foundation project. During the cost control process of the column engineering component data, first is the selection of the concrete strength grade of the column, which is determined according to the structural design calculation and overall cost control requirements. From the perspective of cost control, choosing an appropriate concrete strength grade can effectively control costs on the premise of meeting structural safety. The steel bar configuration of the column is also an important cost control factor. The amount of steel bars is calculated based on the design load, and the impact of the steel bar specifications and models on the cost is considered. In terms of formwork installation of the column, the appropriate type of formwork (such as wooden formwork, steel formwork, or plastic formwork) is selected. Different formworks have different costs, turnover times, and installation difficulties, and need to be comprehensively considered. During the construction process, strict control is carried out on the labor costs of concrete pouring, steel bar binding, and formwork installation to ensure the coordination of construction progress and cost control. Finally, the implementation result of the second engineering component data of the column engineering component data is obtained.

[0107] For the component data of the curtain wall project on the building facade, when controlling the project cost in the order of project cost control, the selection of the curtain wall type (such as glass curtain wall, stone curtain wall or metal curtain wall) is a key factor in project cost control. There are significant differences in material costs, installation process costs and maintenance costs among different types of curtain walls. For example, for a glass curtain wall, the impact of factors such as the type of glass (such as single-layer glass, double-layer insulating glass or triple-layer insulating glass), the thickness of the glass, and the coating requirements on the cost needs to be considered. For a stone curtain wall, the impact of factors such as the variety, specification, thickness of the stone and the processing technology of the stone on the cost needs to be considered. During the installation of the curtain wall, precise control is carried out on the labor cost of installation, the cost of auxiliary materials (such as sealant, hanging parts, etc.) and the rental cost of installation equipment (such as hanging baskets, cranes, etc.). Through these measures, the implementation result of the second engineering component data of the curtain wall project component data is obtained.

[0108] In terms of the installation project of mechanical and electrical equipment, taking the component data of the distribution cabinet project as an example, the project cost is controlled in the order of project cost control. The selection of the distribution cabinet should be determined according to the power load requirements of the entire building, the design requirements of the power supply system and the project cost control target. There are significant differences in cost among distribution cabinets with different capacities and different protection levels. When purchasing a distribution cabinet, different brands and different suppliers in the market should be compared to select the product with the highest cost performance. The installation location of the distribution cabinet will also affect the project cost. Factors such as the laying path of the cable tray and the connection distance to other electrical equipment should be considered to reduce the cable usage and installation cost. During the installation process, strict control is carried out on the installation labor cost, grounding system cost and commissioning cost of the distribution cabinet, so as to obtain the implementation result of the second engineering component data of the distribution cabinet project component data.

[0109] After obtaining the implementation result of the second engineering component data of each engineering component data, a check for result matching should be carried out. If the implementation result of the first engineering component data of each engineering component data among multiple engineering component data matches the implementation result of the second engineering component data, then a project cost control management report indicating that the project cost control of the BIM engineering model has passed 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 indicates 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 the column engineering component data, the budgeted situations of the concrete strength grade, steel usage, formwork type, etc. in the implementation result of the first engineering component data are compared with the actual situations in the implementation result of the second engineering component data. If they all match, then the results of the column engineering component data are matched. For the curtain wall engineering component data, the curtain wall type, material cost budget, installation process cost budget, etc. in the implementation result of the first engineering component data are compared with the actual situations in the implementation result of the second engineering component data. If it does not exceed the budget range and all indicators match, then the results of the curtain wall engineering component data are matched. For the power distribution cabinet engineering component data, the power distribution cabinet selection, procurement cost budget, installation location planning, etc. in the implementation result of the first engineering component data are checked against the actual situations in the implementation result of the second engineering component data. If they are all consistent, then the results of the power distribution cabinet engineering component data are matched.

[0111] When the implementation results of the first engineering component data and the second engineering component data of all engineering component data are all matched, the generated project cost control management report details the project cost control situation of the entire BIM engineering model. The report content includes the original budget, actual expenditure, cause analysis of cost savings or overruns, etc. for 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 was optimized during construction, reducing material waste; if there is cost overrun, it may be because the geological conditions changed, increasing the construction difficulty and requiring additional treatment measures. For the column engineering component data, the cost change may be related to factors such as concrete price fluctuations and steel usage adjustments. The cost change of the curtain wall engineering component data may be related to factors such as material price fluctuations and installation process adjustments. The cost change of the power distribution cabinet engineering component data may be related to adjustments in the power distribution cabinet selection and market price fluctuations. This project cost control management report accurately reflects the implementation situation of the BIM engineering model in the project cost control process and provides an important basis for the project's cost management.
