[0002] BIM is an abbreviation for the content modeling method of building complex information, and it is the basic model of large-scale digital related information; BIM is to establish a virtual three-dimensional model of a building project, and use digital technology to provide a complete building project information database consistent with the actual situation for this model. This information database not only contains geometric information, professional attributes and status information describing building components, but also contains status information of non-component objects.

The system includes: an engineering information classification module, a data acquisition module, a BIM model establishment module, a stage prediction calculation module, a stage cost analysis module, and an adjustment module;

[0038] The engineering information classification module is used to collect various types of engineering information to obtain engineering data, and classify the engineering data;

[0039] The data acquisition module is used to respectively acquire cost data of different categories in the project, and store the acquired cost data separately according to the categories;

[0044] As can be seen from the above, first, collect various engineering information to obtain engineering data, classify the engineering data, acquire different category cost data in the classified engineering data, then create a BIM model, integrate the above-obtained classified engineering data and different category cost data in the classified engineering data into the BIM model to obtain an engineering unit module, use the engineering unit module to predict and calculate the budget costs of various costs in multiple stages to obtain the multi-stage predicted costs, and then compare and analyze the multi-stage predicted costs with the multi-stage actual costs to obtain the multi-stage comparative analysis results. The subsequent cost can be adjusted according to the comparative analysis results of each stage, and the cost can be refinedly managed and controlled to ensure that the cost reaches the maximum benefit.

[0045] Embodiment 2:

[0046] Specifically, the categories into which the engineering information classification module divides the engineering data include: five engineering data units, namely, building engineering units, highway engineering units, municipal engineering units, railway engineering units, and water transportation engineering units.

[0047] Specifically, the data acquisition module is used to acquire different categories of cost data for construction engineering units, highway engineering units, municipal engineering units, railway engineering units, and water transportation engineering units respectively.

[0048] Specifically, the cost data includes material price data, labor cost data, equipment cost data, subcontracting process cost data, project change and claim data, project settlement cost data, and other relevant data. Among them, the other relevant data is the cost data of tax policies and environmental protection policies in the project area.

[0049] The material price data, labor cost data, equipment cost data, subcontracting process cost data, project change and claim data, project settlement cost data, and other relevant data are stored independently respectively.

[0050] Specifically, after the BIM model is constructed, the BIM model establishment module integrates five types of engineering data units, namely construction engineering units, highway engineering units, municipal engineering units, railway engineering units, and water transportation engineering units, and material price data, labor cost data, equipment cost data, subcontracting process cost data, project change and claim data, project settlement cost data, and other relevant data into the BIM model to obtain five types of engineering unit modules.

[0051] Specifically, the five types of engineering unit modules include construction engineering unit modules, highway engineering unit modules, municipal engineering unit modules, railway engineering unit modules, and water transportation engineering unit modules.

[0052] Furthermore, each of the construction engineering unit module, highway engineering unit module, municipal engineering unit module, railway engineering unit module, and water transportation engineering unit module includes material price, labor cost, equipment cost, subcontracting process cost, project change and claim, project settlement cost, and other relevant costs.

[0053] As can be seen from the above, the engineering data is divided into five types of engineering data units, namely construction engineering units, highway engineering units, municipal engineering units, railway engineering units, and water transportation engineering units. Then, different categories of cost data for the above five types of engineering data units are acquired: material price data, labor cost data, equipment cost data, subcontracting process cost data, project change and claim data, project settlement cost data, and other relevant data. The above data is integrated into the BIM model to achieve data integration. On this basis, construction engineering unit modules, highway engineering unit modules, municipal engineering unit modules, railway engineering unit modules, and water transportation engineering unit modules are obtained. Each of the above five unit modules contains material price, labor cost, equipment cost, subcontracting process cost, project change and claim, project settlement cost, and other relevant costs, which can improve the energy efficiency and quality of cost management and achieve cost control for the entire process of the project.

[0054] Example 3:

[0055] Specifically, the stage prediction calculation module divides the construction stage into the early stage, the middle stage, and the late stage, and predicts and calculates the engineering material prices, labor costs, equipment costs, subcontracting process costs, project change and claim costs, project settlement costs, and other related costs in these three stages to obtain the predicted cost in the early stage, the predicted cost in the middle stage, and the predicted cost in the late stage.

[0056] Specifically, the stage cost analysis module compares and analyzes the predicted cost in the early stage, the predicted cost in the middle stage, and the predicted cost in the late stage with the actual cost in the early stage, the actual cost in the middle stage, and the actual cost in the late stage to obtain the comparison result in the early stage, the comparison result in the middle stage, and the comparison result in the late stage.

[0057] Specifically, when analyzing the project cost and cost, the stage cost analysis module uses the earned value method. Through the evaluation of cost variance, schedule variance, cost performance index, and schedule performance index, the effective analysis of project cost and cost is realized. The calculation formulas are as follows:

[0058] CV = BCWP - ACWP

[0059] SV = BCWP - BCWS

[0060] CPI = BCWP / ACWS

[0061] SPI = BCWP / BCWS

[0062] Among them, CV is the cost variance, BCWP is the budgeted cost of work performed, ACWP is the actual cost of work performed, BCWS is the budgeted cost of work scheduled (predicted and calculated cost), SV is the schedule variance, CPI is the cost performance indicator, and SPI is the schedule performance indicator.

[0063] Specifically, the adjustment module adjusts the cost of subsequent projects according to the comparison results in the early stage, the comparison results in the middle stage, and the comparison results in the late stage, and according to the analysis results of each stage.

[0064] As can be seen from the above, the construction stage is divided into the preliminary stage, the intermediate stage and the late stage. The engineering material prices, labor costs, equipment costs, subcontracting process costs, project change and claim costs, project settlement costs and other related costs in the three stages are predicted and calculated to obtain the corresponding predicted costs. The earned value analysis method is used to effectively analyze the project cost and cost, and compare and analyze them with the actual costs in the preliminary stage, the intermediate stage and the late stage respectively. The comparison results in the three stages can be obtained, and the subsequent usage costs can be adjusted according to the comparison results of each stage, clarifying the cost optimization space in the actual construction process of each stage, providing a reference for decision-making management, and improving the accuracy and reliability of the final settlement cost.
