[0018] Embodiment 1

[0019] like Figure 1 As shown, the present application provides a BIM-based project management method, the method comprising:

[0020] P10: Connect to the project management database of the target engineering project, obtain multiple project basic data sets of multiple construction divisions, and build multiple BIM models based on the BIM system and the multiple project basic data sets;

[0021] Specifically, the target engineering project has multiple construction divisions, and each construction division has a separate construction scope, construction period requirements and resource allocation. Managing multiple construction divisions separately can improve project management efficiency and accuracy. By connecting to the project management database of the target engineering project, multiple project basic data sets of multiple construction divisions are extracted from the project management database. The project basic data may include design drawings, material lists, construction schedules, cost budgets, etc. The extracted data is cleaned and sorted, and then imported into the BIM system. In the BIM system, the imported project basic data sets are used to build models, including the construction of civil engineering models, electromechanical equipment models, pipeline models, etc. of buildings, and multiple BIM models corresponding to multiple construction divisions are obtained.

[0022] For example, the GTJ quantity calculation model can be imported into BIMMAKE software for component processing, so as to quickly obtain the construction BIM model. After fine-tuning the construction BIM model, it can be exported to Revit software for use, from the original one-model-for-multiple-use basis to the one-model-to-end comprehensive management, reducing repeated modeling and realizing more practical applications of quantity calculation models in the construction stage.

[0023] P20: Performing project simulation based on the multiple BIM models to obtain multiple project simulation results at a first time node, wherein the multiple project simulation results include multiple simulation quality data, multiple simulation cost data, and multiple simulation project progress;

[0024] Optionally, select appropriate construction simulation software or plug-in, and use the multiple BIM models to perform project simulation, set the parameters required for simulation according to project requirements and actual conditions, such as construction methods, material properties, staffing, etc., import the constructed multiple BIM models into the simulation software for simulation, and extract multiple project simulation results of the first time node from the simulation software, including multiple simulation quality data of multiple construction divisions, multiple simulation cost data, and multiple simulation project progress as basic data for project feasibility evaluation.

[0025] P30: In the multiple construction divisions, judging whether the multiple simulation quality data are qualified and the degree of unqualified according to the preset construction standards, and generating multiple quality judgment results;

[0026] It should be understood that the construction quality standards within the industry or enterprise are collected and organized into preset construction standards applicable to this project, and the simulation quality data of each construction division is extracted from the project simulation results. In each construction division, the simulation quality data is judged one by one according to the preset construction standards to determine whether each simulation quality data meets the requirements of the preset construction standards and whether it is qualified. For unqualified simulation quality data, the degree of unqualifiedness is further determined, such as slightly unqualified, moderately unqualified or seriously unqualified, thereby forming multiple quality judgment results for multiple construction divisions.

[0027] P40: In the multiple construction divisions, judging the multiple simulation cost data according to the preset construction budget, and generating multiple cost judgment results;

[0028] Further, such as Figure 2 As shown, step P40 of the embodiment of the present application also includes:

[0029] P41: Acquire first simulation cost data of the first construction division, wherein the first simulation cost data includes total cost data, as well as raw material cost data, labor cost data, and other cost data;

[0030] P42: When the total cost data meets the total budget in the preset construction budget, the surplus cost is obtained and a surplus cost judgment result is generated;

[0031] P43: Otherwise, compare the raw material cost data, labor cost data, and other cost data with the raw material budget, labor budget, and other budget in the preset construction budget respectively;

[0032] P44: If the difference between any cost data item in the comparison result and the budget exceeds the difference threshold, an investigation instruction is generated to conduct an expenditure investigation on the cost item;

[0033] P45: Otherwise, the excess part will be added to the missing part, and the remaining missing part will be used as the missing cost to generate the missing cost judgment result.

[0034] Optionally, based on the design data, the engineering budget of the target engineering project is obtained and used as the preset construction budget. The multiple simulated cost data are judged with reference to the preset construction budget to obtain the cost control judgment results of each construction section, that is, to determine whether the construction cost of the project is within the budget.

[0035] Specifically, the first simulation cost data of the first construction division is obtained, including total cost data, as well as raw material cost data, labor cost data, and other cost data. The total cost data, that is, the sum of the raw material cost data, labor cost data, and other cost data, can reflect the estimated cost situation of the first construction division at the simulation time node.

[0036] Furthermore, the total cost data of the first construction division is compared with the total budget in the preset construction budget. If the total cost data meets the requirements of the total budget, that is, the total cost is within the budget, the surplus cost is calculated to generate a surplus cost judgment result. The surplus cost refers to the unused part of the budget, which can reflect the construction division's potential in cost control.

[0037] Furthermore, if the total cost data does not meet the requirements of the total budget, that is, the total cost exceeds the budget range, the raw material cost data, labor cost data and other cost data are compared with the corresponding budget items in the preset construction budget, and the cost items that exceed the budget are screened out. If it is found that the difference between any cost data and the budget exceeds the set difference threshold, it means that there is abnormal or unreasonable expenditure in this cost, then an investigation instruction is generated to conduct an expenditure investigation on the cost item to find out the reasons for the abnormal expenditure, including whether there is waste, miscalculation or poor management, so as to take timely measures to correct it.

[0038] If the comparison results of all cost items do not exceed the difference threshold, but the total cost still exceeds the total budget, the part exceeding the budget will be supplemented to the part lacking the budget to balance the various costs. If there are still cost items that cannot meet the budget requirements after supplementation, the remaining lacking part will be regarded as the lacking cost, and the lacking cost judgment result will be generated as a reference for cost control optimization.

[0039] Further, such as Figure 3 As shown, step P41 of the embodiment of the present application also includes:

[0040] P41-1: When the first quality judgment result is unqualified, obtain a first unqualified degree;

[0041] P41-2: When the first unqualified degree exceeds a preset unqualified degree, a rework instruction is generated, and based on the rework instruction, the first BIM model is controlled to perform a rework simulation to generate a rework cost;

[0042] P41-3: When the first unqualified degree does not exceed the preset unqualified degree, a construction improvement instruction is generated, and the first BIM model is controlled to perform a construction improvement simulation based on the construction improvement instruction, and a construction improvement cost is generated according to the construction improvement simulation result;

[0043] P41-4: Add the rework cost or the construction improvement cost to the first simulation cost data.

[0044] It should be understood that when the first quality judgment result is unqualified, that is, the simulated quality of the first construction section does not meet the preset construction standards, the first degree of unqualifiedness is further obtained. The first degree of unqualifiedness is a quantitative indicator used to measure the severity of non-compliance with quality standards. According to the preset unqualified degree level classification, the specific level of the first degree of unqualifiedness can be determined.

[0045] Furthermore, when the first unqualified degree exceeds the preset unqualified degree, indicating that the construction division has serious quality problems, a rework instruction is generated, and the first BIM model is controlled according to the rework instruction to perform a rework simulation, including repair, replacement or reconstruction, and the rework cost is obtained.

[0046] Furthermore, when the first unqualified degree does not exceed the preset unqualified degree, that is, although there are quality problems in the current construction division, it has not reached the level that requires rework, a construction improvement instruction is generated, and based on the construction improvement instruction, the first BIM model is controlled to perform a construction improvement simulation, including improving the construction plan, strengthening quality control, and then re-constructing the simulation, obtaining the construction improvement simulation results, and generating the construction improvement cost based on the construction improvement simulation results.

[0047] Furthermore, the rework cost and the construction improvement cost are both additional expenses in the construction process. Adding the rework cost or the construction improvement cost to the first simulation cost data can more comprehensively reflect the cost situation of the construction division and provide more accurate cost forecasting and decision-making basis.

[0048] Furthermore, step P41-3 of the embodiment of the present application also includes:

[0049] P41-31: Generate a construction improvement space according to the construction requirements, wherein the construction improvement space includes a construction process adjustment space, a spare construction material library, a spare construction equipment library, and a construction personnel library, wherein the construction personnel library includes a plurality of ordinary workers, a plurality of technicians, and a plurality of administrators;

[0050] P41-32: Obtain current construction data as original construction decision;

[0051] P41-33: Use the first BIM model to simulate the original construction decision, and based on the construction improvement quality evaluation function, perform quality evaluation on the simulation result to obtain the original construction improvement quality evaluation value;

[0052] P41-34: Taking the original construction decision as the starting point, backtracking search is performed in the construction improvement space to extract the first construction improvement decision;

[0053] P41-35: Use the first BIM model to simulate the first construction improvement decision, and based on the construction improvement quality evaluation function, perform quality evaluation on the simulation result to obtain a first construction improvement quality evaluation value;

[0054] P41-36: If the first construction improvement quality evaluation value is greater than the original construction improvement quality evaluation value, the first construction improvement decision is used to replace the original construction decision as the current optimal construction improvement decision;

[0055] P41-37: Otherwise, continue to use the original construction decision as the current optimal construction improvement decision;

[0056] P41-38: Continue to iterate and optimize in the construction improvement space until the preset constraint conditions are met, stop iterating, and output the current optimal construction improvement decision at that time as the construction improvement plan;

[0057] P41-39: Based on the construction improvement plan, a construction improvement simulation is performed on the first BIM model to generate a construction improvement simulation result.

[0058] In a possible embodiment of the present application, a construction improvement space is generated according to the construction requirements of the project, and the construction improvement space includes a construction operation process adjustment space, a spare construction material library, a spare construction equipment library, and a construction personnel library. The construction personnel library includes a plurality of ordinary workers, a plurality of technicians, and a plurality of administrators. The composition of the construction personnel can be adjusted through the construction personnel library, for example, by adding administrators or technicians, to improve the management level.

[0059] Furthermore, the current construction data is obtained and used as the original construction decision. The original construction decision is simulated using the first BIM model to predict the construction quality and cost of the original construction decision, that is, the simulation results are obtained. Based on the simulation results, corresponding parameters are obtained and substituted into the construction improvement quality evaluation function for quality evaluation to obtain the original construction improvement quality evaluation value.

[0060] Furthermore, starting from the original construction decision, a backtracking search is performed in the construction improvement space to find possible improvement solutions, such as extracting a first construction improvement decision, that is, a potential optimization solution based on current data and spatial constraints, through a search algorithm. Similarly, the first construction improvement decision is simulated using the first BIM model, and corresponding parameters are collected according to the simulation results, substituted into the construction improvement quality evaluation function for quality evaluation, and the first construction improvement quality evaluation value is obtained.

[0061] Furthermore, if the first construction improvement quality assessment value is greater than the original construction improvement quality assessment value, the first construction improvement decision will replace the original construction decision as the current optimal construction improvement decision, otherwise, the original construction decision will continue to be used as the current optimal construction improvement decision. Similarly, the iterative optimization is continued in the construction improvement space until the preset constraints are met, for example, the preset number of times is reached, the iteration is stopped, and the current optimal construction improvement decision at that time is output as the final construction improvement plan. Based on the construction improvement plan, the first BIM model is simulated for construction improvement to generate construction improvement simulation results.

[0062] Furthermore, step P41-33 of the embodiment of the present application also includes:

[0063] P41-331: Use the first BIM model to simulate the original construction decision, and during the simulation process, record safety accidents and safety hazards in the construction simulation as the first simulation result;

[0064] P41-332: After the simulation is completed, the simulated construction time is obtained as the second simulation result, and the simulated resource utilization efficiency is obtained as the third simulation result;

[0065] P41-333: According to the preset construction standard, the simulation data is judged whether it is qualified, and the fourth simulation result is generated;

[0066] P41-334: normalizing the first simulation result, the second simulation result, the third simulation result, and the fourth simulation result, and performing quality assessment on the normalized results based on the construction improvement quality assessment function to obtain the original construction improvement quality assessment value;

[0067] Wherein, the construction improvement quality evaluation function is as follows:

[0068] ;

[0069] in, is the construction improvement quality evaluation value of the i-th construction decision, is the safety hazard factor, is the construction time coefficient, is the resource utilization efficiency coefficient, , , are weights respectively, and the sum is 1, The result of judging whether the result is qualified or not is 1 if the result is qualified and 0 if the result is unqualified.

[0070] Optionally, the specific process of using the first BIM model to simulate the original construction decision and conducting quality assessment on the simulation result based on the construction improvement quality assessment function may be: using the first BIM model to simulate the original construction decision, and during the simulation process, recording safety accidents and safety hazards in the construction simulation as the first simulation result, that is, as the first quality assessment parameter. Furthermore, after the simulation is completed, the simulated construction time is obtained as the second simulation result, that is, the second quality assessment parameter, and the simulated resource utilization efficiency is obtained as the third simulation result, that is, the third quality assessment parameter.

[0071] Furthermore, the simulation data is judged to be qualified according to the preset construction standards, for example, the preset construction standards such as construction quality requirements, safety standards, and environmental protection requirements are judged to generate a fourth simulation result, that is, a fourth quality assessment parameter.

[0072] Furthermore, the first simulation result, the second simulation result, the third simulation result, and the fourth simulation result are normalized, that is, the simulation results of different dimensions and units are converted into comparable unified scales, and the normalized multiple simulation results are substituted into the construction improvement quality assessment function for quality assessment calculation to obtain the original construction improvement quality assessment value. Among them, the construction improvement quality assessment function is: ; is the construction improvement quality evaluation value of the i-th construction decision. The larger the evaluation value, the better the corresponding construction decision. is the safety hazard factor, is the construction time coefficient, is the resource utilization efficiency coefficient, , , are weights respectively, and the sum is 1, The result of judging whether the result is qualified or not is 1 if the result is qualified and 0 if the result is unqualified.

[0073] Furthermore, step P41-34 of the embodiment of the present application also includes:

[0074] P41-341: Randomly generate optimal construction decisions, the generation of the optimal construction decisions is based on the following random formula: ;

[0075] in, represents the i-th optimization item of the optimal construction decision P, Represents the jth optimization sub-item of the i-th optimization item of the optimal construction decision P, i=1,2,3,4, j=1,2,3...N, N represents the number of j-th optimization sub-item, represents the lower bound of the jth optimization item, Represents the upper bound of the jth optimization sub-item, U is a uniformly distributed random function;

[0076] P41-342: Using the random formula, the original construction decision is initialized. The original construction decision is: ;

[0077] P41-343: Generate numbers a and b, where both a and b are random numbers between 0 and 1;

[0078] P41-344: When a<b, the optimal construction decision Elements of optimization and original construction decisions The elements at the same position in the same construction are exchanged to generate a new decision as the first construction improvement decision;

[0079] P41-345: When a ≥ b, the optimal construction decision is abandoned .

[0080] Specifically, starting from the original construction decision, backtracking search is performed in the construction improvement space, and the specific process of extracting the first construction improvement decision may be: writing a random formula: ;in, represents the i-th optimization item of the optimal construction decision P, Represents the jth optimization sub-item of the i-th optimization item of the optimal construction decision P. The number of optimization items i=1, 2, 3, 4 corresponds to the construction improvement space. The construction improvement space includes a construction process adjustment space, a spare construction material library, a spare construction equipment library, and a construction personnel library. There are 4 in total. j=1, 2, 3...N, where N represents the number of the jth optimization sub-item. represents the lower bound of the jth optimization item, It represents the upper bound of the j-th optimization item, and U is a uniformly distributed random function.

[0081] Furthermore, the random formula is used to initialize the original construction decision, and the original construction decision is defined as First, randomly generate a and b, where a and b are both random numbers between 0 and 1. When a<b, the optimal construction decision Elements of optimization and original construction decisions The elements in the same position are exchanged to generate a new decision, and the new decision is used as the first construction improvement decision. When a ≥ b, the optimal construction decision is discarded. Continue to generate random numbers until the first construction improvement decision is obtained.

[0082] P50: encrypting and transmitting the multiple quality judgment results and the multiple cost judgment results to the cloud, and using the construction coordination management module on the cloud to perform coordination management to generate a first management plan;

[0083] It should be understood that the multiple quality judgment results and the multiple cost judgment results are encrypted and transmitted to the cloud, and the construction coordination management module in the cloud performs coordination and management. The construction coordination management module can perform a comprehensive analysis based on the received quality judgment results and cost judgment results, taking into account various construction factors and resource constraints, including optimization of the construction process, adjustment of resource allocation, cost control measures, etc., to generate a first management plan for construction quality and results control.

[0084] P60: Using the progress synchronization management module in the cloud, synchronously manage the progress of the multiple simulation projects and generate a second management plan;

[0085] Specifically, the simulated project progress data of multiple simulated projects are collected, including progress information of each construction stage, such as completion percentage, critical path, progress deviation, etc., and the simulated project progress data is transmitted to the cloud. The progress of the multiple simulated projects is synchronously managed through the progress synchronization management module in the cloud. The progress synchronization management module is a system specially used to manage and coordinate the progress of multiple projects. It can update, compare and analyze the uploaded progress data in real time to ensure the coordination and consistency between the progress of each simulated project, and use the optimization algorithm in the module to optimize and adjust the construction progress to obtain a second management plan. The second management plan can better manage and control the construction progress to ensure that the project can proceed smoothly according to the predetermined goals and requirements.

[0086] P70: Transmit the first management plan and the second management plan to the multiple construction divisions, and perform project management on the multiple construction divisions.

[0087] Exemplarily, the first management plan and the second management plan are transmitted to the multiple construction divisions, and each construction division refers to the corresponding quality, cost and progress control measures in the first management plan and the second management plan to carry out divisional construction to ensure that the construction quality, cost and progress meet expectations. Exemplarily, relevant data is collected through BIM business management, sorted and analyzed, and an enterprise quota library is formed to improve the speed, efficiency and accuracy of bidding project quotations, and to achieve effective prevention of cost risks of bidding projects. Improve construction efficiency and quality, and reduce construction costs and risks.

[0088] Furthermore, the embodiment of the present application further includes step P80, and step P80 further includes:

[0089] P81: Based on the first management scheme and the second management scheme, the multiple BIM models are used to perform construction simulation, and multiple expected quality data, multiple expected cost data, and multiple expected project progress are collected;

[0090] P82: When at the first time node, data collection is performed on the multiple construction divisions to obtain multiple actual quality data, multiple actual cost data, and multiple actual project progress data;

[0091] P83: comparing the plurality of expected quality data and the plurality of expected cost data with the plurality of actual quality data and the plurality of actual cost data, and adjusting the first management scheme when the comparison deviation does not satisfy a first preset comparison deviation;

[0092] P84: Compare multiple expected project progresses with multiple actual project progresses, and when the comparison deviation does not meet the second preset comparison deviation, adjust the second management plan.

[0093] It should be understood that, with reference to the first management plan and the second management plan, the multiple BIM models are used to perform construction simulation, and thereby multiple expected quality data, multiple expected cost data, and multiple expected project progress data are collected as expected construction results.

[0094] Furthermore, in the actual construction process, when the project is at the first time node, such as every week, every month or at the end of a key construction phase, data collection is performed on multiple construction divisions, including collecting multiple actual quality data, multiple actual cost data, and multiple actual project progress data.

[0095] Furthermore, a difference comparison is performed between multiple expected quality data and multiple expected cost data and multiple actual quality data and multiple actual cost data. When the comparison deviation does not meet the first preset comparison deviation, it means that the actual project quality and cost control do not meet the expected standards. In this case, the first management plan is adjusted by optimizing resource allocation, improving construction processes or taking other measures to reduce deviations and improve construction quality and cost control effects.

[0096] Furthermore, multiple expected project progresses are compared with multiple actual project progresses. When the comparison deviation does not meet the second preset comparison deviation, that is, the actual project progress does not meet the expected project progress, the second management plan is adjusted by adjusting the construction plan, optimizing the construction schedule or taking other measures to ensure that the construction progress meets expectations.

[0097] Therefore, the management plan is adjusted by comparing the construction simulation based on the BIM model with the actual construction data to achieve more accurate construction management and optimization.

[0098] In summary, the embodiments of the present application have at least the following technical effects:

[0099] This application uses the project basic data sets of multiple construction divisions to construct multiple BIM models for project simulation, generates multiple quality judgment results and multiple cost judgment results through simulated quality and simulated cost judgment, coordinates and manages the multiple quality judgment results and multiple cost judgment results to generate a first management plan, generates a second management plan through the synchronous management of simulated project progress, and performs project management according to the first management plan and the second management plan.

[0100] Through the integrated management model, the barriers that prevent models and data from being interchangeable at different stages of cost and technology are broken, and the extension and penetration of BIM applications from a single stage to cross-stages is achieved, making the whole process management of the project more convenient, intuitive and efficient, and achieving the technical effect of realizing full-process cost control through BIM and improving project management efficiency and accuracy.
