[0001] This invention relates to the field of engineering investment evaluation technology, and in particular to a BIM-based multi-industry engineering investment evaluation system. Background Technology

[0002] In the current engineering construction process, many serious problems have arisen, such as large errors in engineering investment assessment, low engineering investment efficiency, and engineering investment exceeding the budget, resulting in low efficiency of engineering investment utilization. To solve the above problems, BIM technology is now mostly used for engineering investment control and to improve the efficiency of engineering investment production. However, the application of BIM technology is currently limited, and users do not have a clear and intuitive understanding of the benefits of BIM technology for engineering investment assessment.

[0003] Therefore, the present invention provides a BIM-based multi-industry engineering investment evaluation system. Summary of the Invention

It acquires and summarizes daily construction logs from various construction teams; correlates these logs with EBS, WBS, and Qlist data to obtain initial analysis data for engineering investment assessment; constructs a BIM model; determines the value index system and corresponding value index weights based on the initial analysis data; validates the BIM model; and, after validation, performs corresponding engineering investment assessments based on the user-selected minimum construction units of the BIM model. The system also provides a visual display of the current construction progress and the construction progress of the user-selected minimum construction units. This system effectively controls engineering investment while meeting the user's needs for engineering investment assessment of specific minimum construction units.

[0005] This invention provides a BIM-based multi-industry engineering investment assessment system, comprising:

[0006] Data collection module: Obtain the construction logs filled out by each construction team every day, summarize the construction logs, and at the same time, obtain the EBS, WBS and Qlist list data of this project investment;

[0008] Investment assessment module: Constructs a BIM model, determines the value index system and corresponding value index weights of the BIM model based on the initial analysis data, verifies the BIM model, and after verification, conducts corresponding project investment assessment based on the smallest construction units of the BIM model selected by the user.

[0009] Progress labeling module: Generates the current construction progress based on the construction log and provides a first-type visualization display in conjunction with the overall construction progress of the project. At the same time, based on the project investment assessment, it provides a second-type visualization display of the current construction progress of some of the smallest construction units of the BIM model selected by the user.

[0010] Preferably, the data collection module includes:

[0011] The construction data collection unit is used to obtain the construction logs filled out by each construction team every day and to summarize the construction logs. The construction logs include: the project to which the construction team belongs, the total amount of work done on the project, the amount of work done on the day, and the project construction plan.

[0012] The construction logs are summarized and processed by data analysis, and similar data are merged to obtain the construction data of each construction unit of the project.

[0013] The engineering data collection unit is used to obtain EBS, WBS, and Qlist list data based on the analysis of the project.

[0014] Preferably, the data preprocessing module includes:

[0015] The data preprocessing unit is used to obtain the daily construction volume data from the construction data. The daily construction volume data includes: the construction volume data filled in by each construction team and the construction image record data.

[0016] Image enhancement processing is performed on the construction image recording data, and the enhanced construction image recording data is analyzed to obtain the image construction volume data;

[0017] When the construction volume data in the image is found to be consistent with or within the error range of the construction volume data reported by the corresponding construction team, the construction volume data for that day is determined to be correct. Otherwise, the construction volume data for that day is marked with an error and the image construction volume data is used as the construction volume data for that day.

[0018] The data consistency processing unit is used to analyze and process various types of data in construction data, EBS, WBS, and Qlist inventory data, and to ensure that the formats of various types of data are consistent with the parameters.

[0019] Preferably, the data association module includes:

[0020] The data association unit is used to associate EBS, WBS, and Qlist list data and determine the corresponding data association rules.

[0021] When construction data updates are detected, the construction data is automatically compared and analyzed according to the data association rules, and automatically associated with EBS, WBS and Qlist list data to obtain the initial analysis data for project investment assessment.

[0022] The data update unit, when it detects a change in any data in the engineering data, acquires the corresponding related data and corrects and updates it;

[0023] When construction data updates are detected, only the updated data in the new construction data and the existing construction data will be modified and updated, and the remaining construction data will not be entered and updated again.

[0024] Preferably, the investment evaluation module includes:

[0025] The model building unit is used to build a BIM model based on the basic data of engineering investment assessment and in combination with BIM technology. The basic data of engineering investment assessment includes: engineering requirements, engineering type, engineering scale, engineering plan and initial analysis data of engineering investment assessment.

[0026] When the completeness and quality of the BIM model meet the requirements of the corresponding project, the BIM model is considered to have been successfully created.

[0027] The engineering investment assessment preparation unit is used to analyze engineering requirements, transform them into BIM requirements, establish a BIM control team, and clarify the application standard architecture of the BIM model. When the BIM model is detected to be running normally, all data are correlated normally, and all data formats are consistent, the engineering investment assessment preparation is deemed complete, and practical application analysis is carried out. The application standard architecture of the BIM model includes: software standards, business standards, and model standards.

[0028] The engineering investment assessment and planning unit is used to calculate the engineering quantities of the project based on the BIM model and the BIM historical database, obtain the scope of the BIM model to be calculated, the model accuracy, the amount of data conversion, and the corresponding project time schedule, determine the estimated engineering investment of the corresponding project, and generate the corresponding engineering quantity planning list.

[0029] According to the preset engineering investment estimation rules, the engineering quantity planning list is evaluated. If it is determined that there is an estimation error in the engineering quantity planning list, it is determined that there is a model error in the corresponding BIM model and the model needs to be modified. Otherwise, the corresponding engineering quantity planning list is output.

[0030] The engineering investment assessment and design unit is used to perform 3D visualization architectural design of engineering drawings based on the planning list of each engineering quantity, automatically associate consistent buildings in engineering drawings from different perspectives, and modify the corresponding associated building components when a modification is detected in a building component.

[0031] Collaboratively design the engineering projects corresponding to each engineering quantity planning list, obtain the collaborative engineering investment assessment amount that meets the basic design requirements of the project, and determine the engineering investment assessment limit for each engineering project by combining the engineering investment estimate of the corresponding project.

[0032] Collision detection is performed on the BIM model to determine the hard and soft collision points between various building components. Based on the preset collision adjustment strategy, the design of the BIM model is adjusted.

[0034] Obtain the target value for each project and determine the corresponding actual value based on the daily construction volume data. When the target value is found to be consistent with the actual value, it is determined that the project investment assessment implementation conforms to the optimal construction plan, and the actual project investment data is collected. Otherwise, it is determined that there is an error in the project investment assessment implementation, and the error is analyzed and processed based on the BIM model.

[0035] The daily construction volume data of each construction team is inspected, and when it is determined to meet the corresponding project completion standards, the corresponding inspection mark is made.

[0036] The engineering investment assessment and optimization unit is used to optimize the BIM model based on the daily construction volume of each construction team, the deviation of engineering investment data, and the error rate of engineering investment data.

[0037] The engineering investment assessment and verification unit is used to analyze the optimized BIM model, determine the value index system of the BIM model, and assign weights to each parameter in the value index system based on construction data and engineering data. The BIM model value index system includes: engineering quantity value index, engineering investment assessment value index, construction progress value index, and design adjustment value index.

[0038] Based on the value index system and corresponding value index weights of the BIM model, a consistency check is performed on the BIM model. When the consistency ratio of the BIM model is found to be lower than the preset consistency ratio, the corresponding BIM model is deemed to have completed the verification and can be applied in actual construction.

[0039] The engineering investment assessment and statistics unit is used to perform statistics on the corresponding construction projects based on the smallest construction units selected by the user in the BIM model, and generate corresponding engineering investment assessments.

[0040] Preferably, the engineering investment evaluation optimization unit includes:

[0041] The model optimization value calculation unit is used to calculate the optimization value of the BIM model based on the daily construction volume of each construction team, the deviation of the project investment data, and the error rate of the project investment data.

[0042]

[0043] Where F is the optimized value of the BIM model; xi1 is the daily construction volume of the i1th construction team of the project; x is the preset daily construction volume of the project; yj1 is the actual engineering investment of the j1th construction project of the project; Yj1 is the engineering investment assessment of the j1st construction project of the project; z1 is the number of errors in the engineering investment data of the project; z2 is the total number of engineering investment data of the project. The weights representing the daily construction volume of the construction team, the deviation of the project investment data, and the error rate of the project investment data on the optimization of the BIM model are respectively; n1 is the total number of construction teams in the project; m1 is the total number of construction projects in the project.

[0044] When the optimized value of the BIM model is detected to be higher than the preset optimized value of the BIM model, it is determined that the BIM model needs to be optimized, and the BIM model is optimized according to the preset model optimization scheme.

[0045] Preferred options also include:

[0046] The minimum construction unit is used to analyze the BIM model, set the minimum construction unit of the BIM model, and establish a one-to-one correspondence with the corresponding building components. Based on the minimum construction unit, the construction log format required by each construction team is generated.

[0047] The user permission unit is used to grant permissions to each user based on preset permission settings rules, and to open access permissions to the corresponding BIM model, allowing users to perform engineering investment assessment operations for the corresponding construction unit.

[0048] The BIM historical database unit is used to establish a BIM historical database, which independently stores the construction data and engineering data of each project throughout the entire process.

[0049] Preferably, the progress marking module includes:

[0050] A type of visual annotation unit is used to generate the current construction progress based on the construction log and to display it in a visual manner in conjunction with the overall construction progress of the project.

[0051] The second type of visualization annotation unit is used to display the current construction progress of some of the smallest construction units of the BIM model selected by the user, based on the project investment assessment.

[0052] Compared with the prior art, the beneficial effects of this application are as follows:

[0053] By acquiring and summarizing the daily construction logs filled out by each construction team, and then correlating these logs with EBS, WBS, and Qlist data, initial analysis data for project investment assessment is obtained. A BIM model is constructed, and based on the initial analysis data, a value index system and corresponding value index weights are determined for the BIM model. The BIM model is then validated. After validation, project investment assessments are performed based on the smallest construction units selected by the user within the BIM model. The current construction progress and the construction progress of the user-selected smallest construction units are visualized. This approach effectively controls project investment while also meeting the user's needs for project investment assessment of specific smallest construction units.

[0064] In this embodiment, the construction log filled out by the construction team every day is used to record the daily workload of each construction team.

[0065] In this embodiment, EBS list data refers to the Engineering Entity Decomposition List, which is used to decompose engineering projects into a series of specific tasks for better planning and management.

[0066] In this embodiment, the WBS list data refers to the project task breakdown list, which is used to further break down the project into more specific tasks and activities in order to conduct investment assessment, task allocation, project acceptance, and cost control.

[0067] In this embodiment, Qlist data refers to the bill of quantities, which is a document that specifically displays the contents of each item in the project and serves as the basis for project budgets, final accounts, and tenders.

[0068] In this embodiment, data association refers to the intelligent sharing and synchronization of construction data with EBS, WBS, and Qlist list data. Based on the analysis and processing of the project, data with influencing relationships are associated. When one data changes, the other lists are modified accordingly, and the related data are also modified synchronously.

[0069] In this embodiment, the initial analysis data refers to the basic data used to analyze the investment assessment of this project.

[0070] In this embodiment, BIM model refers to building information model, which integrates geometric model information, functional requirements and component performance, and unifies all information throughout the entire life cycle of a building project, and displays it in a separately established building model. The displayed content also includes all information in the project investment assessment, project construction progress, project construction process and project maintenance process.

[0071] In this embodiment, the value index system of the BIM model refers to the evaluation index used to evaluate the quality of the BIM model, which often includes the error rate of engineering investment data and the error rate of engineering investment data; the value index weight of the BIM model refers to the weight of each value index system on the quality of the BIM model.

[0072] In this embodiment, the minimum construction unit refers to the construction unit in the BIM model that corresponds to the smallest construction building component that can be used for project investment evaluation, obtained by analyzing the project. For example, the construction unit corresponding to the cement pile in the building is used as the minimum construction unit.

[0073] In this embodiment, project investment assessment refers to the statistical analysis of the construction status of each construction unit of the project, such as construction progress, construction budget, actual construction investment, and expected construction completion time.

[0074] In this embodiment, one type of visualization processing refers to the visual display of the current construction progress.

[0075] In this embodiment, the second type of visualization processing refers to the visualization display of the engineering investment assessment of the smallest construction unit selected by the user.

[0076] In this embodiment, based on the analysis of project requirements, an EBS decomposition template based on the minimum construction unit is formulated to implement refined management of the project.

[0077] The beneficial effects of the above technical solution are as follows: By acquiring and summarizing the daily construction logs filled out by each construction team; by associating the construction logs with EBS, WBS, and Qlist data, initial analysis data for project investment assessment is obtained; a BIM model is constructed, and based on the initial analysis data, the value index system and corresponding value index weights of the BIM model are determined; the BIM model is validated; after validation, corresponding project investment assessments are performed based on the smallest construction units of the BIM model selected by the user; the current construction progress and the construction progress of the smallest construction units selected by the user are visualized; this achieves effective control of project investment and meets the user's needs for project investment assessment of some smallest construction units.

[0078] This invention provides a BIM-based multi-industry engineering investment assessment system, including a data collection module:

[0079] The construction data collection unit is used to obtain the construction logs filled out by each construction team every day and to summarize the construction logs. The construction logs include: the project to which the construction team belongs, the total amount of work done on the project, the amount of work done on the day, and the project construction plan.

[0080] The construction logs are summarized and processed by data analysis, and similar data are merged to obtain the construction data of each construction unit of the project.

[0081] The engineering data collection unit is used to obtain EBS, WBS, and Qlist list data based on the analysis of the project.

[0082] In this embodiment, a corresponding construction log is generated based on the project, and the data standard of the construction log is obtained from EBS, WBS and Qlist list data.

[0083] In this embodiment, the construction log must be filled out daily, and each item must be filled out.

[0084] In this embodiment, the construction log is summarized according to the project progress update cycle, such as daily, weekly and monthly summaries.

[0085] In this embodiment, the construction data is the data obtained by summarizing and processing the construction logs, such as the daily construction volume b1 of project a1 and the daily construction volume b2 of project a2.

[0086] In this embodiment, the EBS, WBS, and Qlist list data are obtained from the analysis of the project.

[0087] The beneficial effects of the above technical solution are: obtaining the construction logs filled out by each construction team every day and summarizing the construction logs is conducive to obtaining the construction progress in real time, and facilitating detailed analysis and display of the project; obtaining EBS, WBS and Qlist list data is conducive to realizing the overall management and control of the project and accelerating the progress of the project.

[0088] This invention provides a BIM-based multi-industry engineering investment assessment system, including a data preprocessing module:

[0089] The data preprocessing unit is used to obtain the daily construction volume data from the construction data. The daily construction volume data includes: the construction volume data filled in by each construction team and the construction image record data.

[0090] Image enhancement processing is performed on the construction image recording data, and the enhanced construction image recording data is analyzed to obtain the image construction volume data;

[0091] When the construction volume data in the image is found to be consistent with or within the error range of the construction volume data reported by the corresponding construction team, the construction volume data for that day is determined to be correct. Otherwise, the construction volume data for that day is marked with an error and the image construction volume data is used as the construction volume data for that day.

[0092] The data consistency processing unit is used to analyze and process various types of data in construction data, EBS, WBS, and Qlist inventory data, and to ensure that the formats of various types of data are consistent with the parameters.

[0093] In this embodiment, the construction volume data reported by each construction team in the daily construction volume data is unique, but the construction image record data is not unique. For example, construction team a1 uploads construction volume data b1, construction image record data c1, and c2.

[0094] In this embodiment, construction image recording data refers to image data obtained by the construction team taking photos of the actual construction progress on site and uploading them. This data is used to analyze and verify whether the construction volume data uploaded by the construction team is correct. For example, if the construction team uploads construction volume data b1, and the construction volume data obtained from the analysis of the construction image recording data is b1, then it is determined that the current construction volume data of the construction team is correct, and data aggregation and subsequent data processing can be performed.

[0095] In this embodiment, image enhancement processing refers to image grayscale processing and image brightness adjustment processing, which are used to obtain on-site construction image data.

[0096] In this embodiment, parameter consistency processing is performed on construction data, EBS, WBS, and Qlist list data. For example, for data c1, the data format, data unit, and data name in each list data are unified.

[0097] The beneficial effects of the above technical solution are: data preprocessing ensures the accuracy of construction log data from each construction team, effectively ensuring the correctness of data sources; parameter consistency processing of construction data, EBS, WBS, and Qlist list data facilitates intelligent data sharing and association, makes it easier to analyze and process construction data in each list data, and is beneficial for subsequent project investment assessment.

[0098] This invention provides a BIM-based multi-industry engineering investment assessment system, including a data association module:

[0099] The data association unit is used to associate EBS, WBS, and Qlist list data and determine the corresponding data association rules.

[0100] When construction data updates are detected, the construction data is automatically compared and analyzed according to the data association rules, and automatically associated with EBS, WBS and Qlist list data to obtain the initial analysis data for project investment assessment.

[0101] The data update unit, when it detects a change in any data in the engineering data, acquires the corresponding related data and corrects and updates it;

[0102] When construction data updates are detected, only the updated data in the new construction data and the existing construction data will be modified and updated, and the remaining construction data will not be entered and updated again.

[0103] In this embodiment, data is associated. For example, data a1 affects data b2 and data c1. When it is detected that data a1 has been modified to data a2, data a1 in each list data is synchronously modified to data a2. At the same time, according to the data association rules, data b2 and data c1 in each list data are synchronously modified.

[0104] In this embodiment, the data association rule refers to the mutual influence and correlation between one piece of data and another piece of data. For example, if data a1 changes to data a2, it will correspondingly affect data b2 to change to data b3.

[0105] In this embodiment, only the data that has been updated between the new construction data and the existing construction data is modified and updated. The remaining construction data is not repeatedly entered and updated. For example, in the construction data of construction team a1, only the construction volume data of the day that has been updated is updated. If the project, construction team, total project volume, and project construction plan have not been updated, they are not repeatedly entered and updated.

[0106] The beneficial effects of the above technical solution are: by linking the data, the initial analysis data for engineering investment assessment is obtained, ensuring that the data updates and changes conform to the real application scenario, laying a data foundation for subsequent engineering investment assessment; and only modifying and updating the data that has been updated effectively avoids data redundancy.

[0107] This invention provides a BIM-based multi-industry engineering investment assessment system, including an investment assessment module:

[0108] The model building unit is used to build a BIM model based on the basic data of engineering investment assessment and in combination with BIM technology. The basic data of engineering investment assessment includes: engineering requirements, engineering type, engineering scale, engineering plan and initial analysis data of engineering investment assessment.

[0109] When the completeness and quality of the BIM model meet the requirements of the corresponding project, the BIM model is considered to have been successfully created.

[0110] The engineering investment assessment preparation unit is used to analyze engineering requirements, transform them into BIM requirements, establish a BIM control team, and clarify the application standard architecture of the BIM model. When the BIM model is detected to be running normally, all data are correlated normally, and all data formats are consistent, the engineering investment assessment preparation is deemed complete, and practical application analysis is carried out. The application standard architecture of the BIM model includes: software standards, business standards, and model standards.

[0111] The engineering investment assessment and planning unit is used to calculate the engineering quantities of the project based on the BIM model and the BIM historical database, obtain the scope of the BIM model to be calculated, the model accuracy, the amount of data conversion, and the corresponding project time schedule, determine the estimated engineering investment of the corresponding project, and generate the corresponding engineering quantity planning list.

[0112] According to the preset engineering investment estimation rules, the engineering quantity planning list is evaluated. If it is determined that there is an estimation error in the engineering quantity planning list, it is determined that there is a model error in the corresponding BIM model and the model needs to be modified. Otherwise, the corresponding engineering quantity planning list is output.

[0113] The engineering investment assessment and design unit is used to perform 3D visualization architectural design of engineering drawings based on the planning list of each engineering quantity, automatically associate consistent buildings in engineering drawings from different perspectives, and modify the corresponding associated building components when a modification is detected in a building component.

[0114] Collaboratively design the engineering projects corresponding to each engineering quantity planning list, obtain the collaborative engineering investment assessment amount that meets the basic design requirements of the project, and determine the engineering investment assessment limit for each engineering project by combining the engineering investment estimate of the corresponding project.

[0115] Collision detection is performed on the BIM model to determine the hard and soft collision points between various building components. Based on the preset collision adjustment strategy, the design of the BIM model is adjusted.

[0116] The engineering investment assessment implementation unit is used to simulate the construction process of the project based on the BIM model and the engineering investment assessment design, formulate various construction schemes that meet the work investment assessment plan, determine the optimal construction scheme of the project according to the actual construction needs, and apply it in practice.

[0117] Obtain the target value for each project and determine the corresponding actual value based on the daily construction volume data. When the target value is found to be consistent with the actual value, it is determined that the project investment assessment implementation conforms to the optimal construction plan, and the actual project investment data is collected. Otherwise, it is determined that there is an error in the project investment assessment implementation, and the error is analyzed and processed based on the BIM model.

[0118] The daily construction volume data of each construction team is inspected, and when it is determined to meet the corresponding project completion standards, the corresponding inspection mark is made.

[0119] The engineering investment assessment and optimization unit is used to optimize the BIM model based on the daily construction volume of each construction team, the deviation of engineering investment data, and the error rate of engineering investment data.

[0120] The engineering investment assessment and verification unit is used to analyze the optimized BIM model, determine the value index system of the BIM model, and assign weights to each parameter in the value index system based on construction data and engineering data. The BIM model value index system includes: engineering quantity value index, engineering investment assessment value index, construction progress value index, and design adjustment value index.

[0121] Based on the value index system and corresponding value index weights of the BIM model, a consistency check is performed on the BIM model. When the consistency ratio of the BIM model is found to be lower than the preset consistency ratio, the corresponding BIM model is deemed to have completed the verification and can be applied in actual construction.

[0122] The engineering investment assessment and statistics unit is used to perform statistics on the corresponding construction projects based on the smallest construction units selected by the user in the BIM model, and generate corresponding engineering investment assessments.

[0123] In this embodiment, the basic data for engineering investment assessment is derived from construction data and engineering data.

[0124] In this embodiment, when the completeness and quality of the BIM model meet the corresponding project requirements, for example, when the completeness is greater than 0.9 and the quality is greater than 0.9, the BIM model is determined to be completed.

[0125] In this embodiment, engineering requirements are analyzed and converted into BIM requirements. For example, if the engineering requirement is that the project is completed within a time period t1, the estimated completion time is t2 (which can be longer or shorter than t1) based on the analysis of the engineering requirements. The engineering progress requirements for each time period are also defined. In other words, the converted BIM requirements are that the project is completed within a time period t2, and the engineering progress requirements for each unit time period (which can be accurate to a day, i.e., 24 hours as a unit time period) are defined.

[0126] In this embodiment, the BIM control team refers to the personnel who operate the BIM software and are responsible for developing BIM-based investment assessments and controlling investments.

[0127] In this embodiment, the bill of quantities refers to the estimated investment of each project obtained from the BIM model. For example, the bill of quantities includes project a1 and project a2, the estimated investment of project a1 is S1, and the project progress requirement A1 for each time period needs to be completed within the time period t3.

[0128] In this embodiment, the preset engineering investment estimation rule is used to determine whether there is an estimation error in the engineering quantity planning list. For example, if the completion time of project a1 is t4 (t4>t3) according to the preset engineering investment estimation rule, then it is determined that there is an estimation error in the corresponding engineering quantity planning list.

[0129] In this embodiment, when a modification to a building component is detected, the corresponding associated building components are modified accordingly, specifically including:

[0130] The modification information of the modified building components is determined, and the modification information is analyzed to obtain the first modification vector in different directions.

[0131] Obtain the first component associated with the modified building structure, determine the modification result of the relevant first component according to each first modification vector, and combine all modification results to obtain the second modification vector of the corresponding first component;

[0132] Calculate the coefficient of first modification contradiction in each second modification vector, and at the same time, calculate the coefficient of second modification contradiction between all first modification vectors and each second modification vector;

[0133]

[0134] in, The first modification is the contradiction coefficient; Indicates the first One modification result; This represents the total number of modification results involved in the corresponding second modification vector; This indicates that the second modified vector, excluding the first... The remaining results after each modification; Indicates all The maximum value in;

[0135]

[0136] in, The second modification is the contradiction coefficient; Represent all the first modification vectors; Represent the th second modification vector corresponding to the first component; Represent all the maximum value in; Represent the total number of second modification vectors included in the corresponding first component;

[0137] Based on the first modification conflict coefficient and the modification direction corresponding to the first modification conflict coefficient being greater than the first preset coefficient, determine the first elimination plan. At the same time, based on the second modification conflict coefficient and the occurrence times of the relevant same modification direction corresponding to the second modification conflict coefficient being greater than the second preset coefficient, determine the second elimination plan;

[0138] Based on the first elimination plan and the second elimination plan, implement the modification of the relevant first component.

[0139] In this embodiment, the determination of the plan is based on the plan database. It is based on any combination of different modification coefficients, modification directions, occurrence times, etc. The matching plan is convenient to directly retrieve. The main purpose is to eliminate contradictions to ensure the rationality of subsequent component modification.

[0140] In this embodiment, preset the engineering investment estimation rules, for example, the upper limit of the daily construction volume of the construction team.

[0141] In this embodiment, determine the engineering investment evaluation limit for each engineering project. For example, determine that the engineering investment evaluation limit for engineering project a1 is d1~d2. If the engineering investment evaluation is lower than d1, there will be a problem that the engineering project a1 cannot be completed as scheduled. If the engineering investment evaluation is higher than d2, there will be a problem of waste of working funds for the engineering project a1.

[0142] In this embodiment, compare the engineering investment evaluation limit of each engineering project with the corresponding actual investment situation and the corresponding actual completion situation of the engineering investment, determine whether there is abnormal data, and conduct corresponding abnormal warnings for the abnormal data. For example, determine that the engineering investment evaluation limit for engineering project a1 is d1~d2, the corresponding actual investment situation is d3 (d3 < d1), and the corresponding actual completion situation of the engineering investment is 1 (actual progress of engineering investment / theoretical progress of engineering investment). Then it is determined that there is an abnormality in the actual investment situation of the engineering investment, and the corresponding abnormal warning for reminding to adjust the engineering investment is executed.

[0143] In this embodiment, visually display the engineering investment evaluation limit, the corresponding actual investment situation, and the corresponding actual completion situation of each engineering project.

[0144] In this embodiment, collision detection of the BIM model refers to the detection of conflicts in the actual physical positions of various building components. Hard collision points refer to conflicts with physical overlap and cannot be adjusted; soft collision points refer to conflicts that do not meet the relevant requirements and can be adjusted.

[0145] In this embodiment, the acceptance mark refers to the mark used to determine whether the project has been completed, and is used to ensure the actual construction quality.

[0146] In this embodiment, engineering investment data deviation refers to the inconsistency between actual data and model data, but the error is acceptable; engineering investment data error refers to the inconsistency between actual data and model data, and the error is unacceptable.

[0147] In this embodiment, consistency verification refers to the verification operation performed on the BIM model based on the value index system and corresponding value index weights of the BIM model. For example, when the consistency ratio e1 < 0.1 (preset consistency ratio), the corresponding BIM model verification is determined to be complete.

[0148] The beneficial effects of the above technical solution are: determining the value index system and corresponding value index weights of the BIM model, verifying the BIM model, which helps the BIM model conform to the actual construction situation of the project and effectively control the project investment assessment; and conducting corresponding project investment assessments based on the minimum construction units of the BIM model selected by the user, thus meeting the user's needs for project investment assessment of the minimum construction units.

[0149] This invention provides a BIM-based multi-industry engineering investment assessment system, including an engineering investment assessment optimization unit comprising:

[0150] The model optimization value calculation unit is used to calculate the optimization value of the BIM model based on the daily construction volume of each construction team, the deviation of the project investment data, and the error rate of the project investment data.

[0151]

[0152] Where F is the optimized value of the BIM model; xi1 is the daily construction volume of the i1th construction team of the project; x is the preset daily construction volume of the project; yj1 is the actual engineering investment of the j1th construction project of the project; Yj1 is the engineering investment assessment of the j1st construction project of the project; z1 is the number of errors in the engineering investment data of the project; z2 is the total number of engineering investment data of the project. The weights representing the daily construction volume of the construction team, the deviation of the project investment data, and the error rate of the project investment data on the optimization of the BIM model are respectively; n1 is the total number of construction teams in the project; m1 is the total number of construction projects in the project.

[0153] When the optimized value of the BIM model is detected to be higher than the preset optimized value of the BIM model, it is determined that the BIM model needs to be optimized, and the BIM model is optimized according to the preset model optimization scheme.

[0154] In this embodiment, the daily construction volume data of each construction team may be inconsistent, and the daily construction volume data of the same construction team may also be inconsistent.

[0155] In this embodiment, when the optimized value of the BIM model is detected to be higher than the preset optimized value of the BIM model, for example, the preset optimized value of the BIM model is a1, and the calculated optimized value of the BIM model is a2 higher than a1, it is determined that the BIM model needs to be optimized.

[0156] In this embodiment, the calculation time period for calculating the optimized value of the BIM model is determined according to the accuracy of the engineering investment assessment. For example, when the engineering investment assessment accuracy is b1 (high accuracy), a 1-month time period is used to calculate the optimized value, and when the engineering investment assessment accuracy is b2 (low accuracy), a 3-month time period is used to calculate the optimized value.

[0157] In this embodiment, a preset model optimization scheme is used. For example, preset model optimization scheme c1 re-evaluates the investment of each project in the project; preset model optimization scheme c2 optimizes the construction team's construction log entry to ensure that the data source is correct.

[0158] The beneficial effects of the above technical solution are: based on the daily construction volume of each construction team, the deviation of project investment data, and the error rate of project investment data, the optimized value of the BIM model can be calculated, which helps to determine whether the BIM model needs to be optimized and adjusted, so that the BIM model conforms to the actual changes in the project progress.

[0159] This invention provides a BIM-based multi-industry engineering investment assessment system, which further includes:

[0160] The minimum construction unit is used to analyze the BIM model, set the minimum construction unit of the BIM model, and establish a one-to-one correspondence with the corresponding building components. Based on the minimum construction unit, the construction log format required by each construction team is generated.

[0161] The user permission unit is used to grant permissions to each user based on preset permission settings rules, and to open access permissions to the corresponding BIM model, allowing users to perform engineering investment assessment operations for the corresponding construction unit.

[0162] The BIM historical database unit is used to establish a BIM historical database, which independently stores the construction data and engineering data of each project throughout the entire process.

[0163] In this embodiment, the smallest construction unit, such as the corresponding construction unit of each cement pile in the BIM model, is used to represent the most basic data of the project.

[0164] In this embodiment, based on the smallest construction unit, a construction log format is generated that each construction team needs to fill in. For example, each construction team fills in the number of cement piles completed and the corresponding completion quality each day.

[0165] In this embodiment, permissions are granted to each user based on preset permission setting rules, and access to the corresponding BIM model is opened. For example, user permissions are divided into three categories (a1, a2, and a3 from largest to smallest). Users with a1 permission can select the smallest construction unit of all projects in the project and then perform statistics on the construction of that part. Users with a2 permission can select the smallest construction unit of a project in the project (the project includes projects b1, b2, b3, and b4; for example, the user is allowed to access project b4) and then perform statistics on the construction of that part.

[0166] The beneficial effects of the above technical solution are: setting a minimum construction unit is conducive to the accuracy of project investment assessment and facilitates corresponding optimization and adjustment; setting user permissions can effectively utilize BIM model data and improve data usage efficiency; establishing a BIM historical database can provide experience data for subsequent new projects, and at the same time, it is conducive to management and evaluation.

[0167] This invention provides a BIM-based multi-industry engineering investment assessment system, including a progress marking module:

[0168] A type of visual annotation unit is used to generate the current construction progress based on the construction log and to display it in a visual manner in conjunction with the overall construction progress of the project.

[0169] The second type of visualization annotation unit is used to display the current construction progress of some of the smallest construction units of the BIM model selected by the user, based on the project investment assessment.

[0170] In this embodiment, the current construction progress is generated based on the construction log. For example, the current construction progress a1 is generated based on the construction log and displayed in red, while the overall construction progress a2 is displayed in gray. The current progress is displayed intuitively and visually, making it easy for users to understand the current construction progress.

[0171] In this embodiment, one type of visualization can adjust the time period, such as displaying daily construction progress, weekly construction progress, and monthly construction progress.

[0172] In this embodiment, the visualization includes the estimated construction completion time, the current time period, the completed construction data, and the construction data to be completed in subsequent time periods. For example, the construction progress is displayed using a monthly cycle. If the estimated construction completion time is in month t1 and the current construction is in month t2, then the current construction data is visualized in month t1, and the estimated construction progress for each month from month t2 to month t1 is visualized.

[0173] In this embodiment, two types of visualization are displayed. For example, if the user selects the smallest construction units c1, c2, and c3, the corresponding project investment assessment is performed, and the corresponding current construction progress data a3 is obtained and displayed in blue.

[0174] In this embodiment, when an abnormal progress is detected in both a type I visualization and a type II visualization, for example, if the current construction progress a1 in a type I visualization is lower than the preset construction progress, it is determined that there is an abnormal construction progress; if the construction progress data of the smallest construction unit c1 selected by the user in a type II visualization is lower than the preset construction progress, it is determined that the corresponding current construction progress data a3 is abnormal, and then a visual warning is issued for the corresponding construction progress abnormality.

[0175] The beneficial effects of the above technical solution are: firstly, it provides a visual display of the current construction progress, which is conducive to intuitive understanding of the current construction progress and facilitates project investment assessment; secondly, it provides a visual display of the current construction progress of some of the smallest construction units of the BIM model selected by the user, which meets the user's need to understand the project progress and is conducive to the user's project investment assessment.

[0176] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
