Description

Technical Field

[0001] The present invention belongs to the technical field of municipal infrastructure management, and more specifically, relates to an operating method for an aging model of an assembled anti-collision component based on BIM5D technology. Background Art

[0002] In recent years, my country's urbanization and infrastructure construction have developed rapidly. At the same time, the domestic digitalization process has been accelerating. The construction industry generally recognizes that the engineering information carrier function of Building Information Modeling (BIM) technology is the best means to solve the entire life cycle of buildings.

[0003] BIM technology has become the mainstream technology in the construction industry and has been widely used in many aspects of construction projects. It has gradually developed from traditional two-dimensional architectural drawings to three-dimensional visualization, 4D (three-dimensional + time), 5D (three-dimensional + time + cost), and even nD (five-dimensional + comprehensive analysis and application of all aspects). Progress and cost control runs through all stages of the project. The ability to control the progress and cost of the project at the same time is the key to whether the project is profitable. However, the cumbersome construction process and complex personnel composition bring certain resistance to the profit and progress of the construction project. Therefore, it is very necessary to use the BIM-5D model to control the progress-cost and predictive correction of the prefabricated bridge anti-collision components. Summary of the invention

[0004] In view of the above defects or improvement needs of the prior art, the present invention proposes a prefabricated component aging analysis method based on BIM5D technology, which can conveniently use BIM5D technology to analyze data during project construction and provide reasonable information support for decision makers of the builder and construction party in a timely manner.

[0005] To achieve the above object, the present invention provides a method for analyzing the aging of prefabricated components based on BIM5D technology, comprising:

[0006] Use modeling software to perform 3D modeling of the construction project and input the bill of quantities into the corresponding component type parameters in the model;

[0007] Compile construction project schedule information;

[0008] Use BIM5D technology to integrate cost information and schedule information, and analyze the three-dimensional model of each task based on the WBS work breakdown structure and earned value method;

[0009] Provide real-time project progress and funding changes through time and project dimensions, evaluate the degree of deviation, analyze the causes of deviation and propose corrective measures.

[0010] In some optional implementation schemes, the three-dimensional modeling of the construction project using modeling software and inputting the bill of quantities into the corresponding component type parameters in the model include:

[0011] 3D modeling is performed based on the CAD 2D drawings of the construction project, and the specific information in the project bill of quantities is input into the 3D model obtained by modeling to assign corresponding relevant parameters to the components.

[0012] In some optional implementation schemes, the compiling of construction project schedule information includes:

[0013] Prepare plans and Gantt charts based on construction project schedule information to allocate task resources, generate construction schedules, track progress, analyze quantities, and manage budgets.

[0014] In some optional implementation schemes, the cost information includes basic project information, contract budget cost, planned budget cost and actual cost; the schedule information includes planned schedule and actual schedule.

[0015] In some optional implementation schemes, the basic project information is respectively based on the WBS work breakdown structure method to name the project serial number, formulate the project code, the project name and the measurement unit.

[0016] In some optional implementation schemes, the contract budget costs are project specific time, planned completed works (WS) and contract unit price (CC). The contract budget cost information is determined according to the relevant provisions in the construction contract.

[0017] In some optional implementation schemes, the planned budget costs are respectively the specific time of the project, the planned completed work volume (WS) and the budget unit price (BC).

[0018] In some optional implementation schemes, the actual costs are project specific time, completed work (WP) and actual unit price (AC). The actual costs are recorded and updated in real time by construction site technicians.

[0019] In some optional implementation schemes, the planned progress consists of a planned start time, a planned completion time and a planned progress days.

[0020] In some optional implementation schemes, the actual progress consists of actual start time, actual completion time and actual progress days respectively.

[0021] In some optional implementation schemes, the time dimensions include time interval, basic parameters, and evaluation indicators; the project dimensions include project name, basic parameters, and evaluation indicators.

[0023] In some optional implementation schemes, the evaluation indicators are schedule deviation (SV), cost deviation (CV), schedule performance index (SPI), and cost performance index (CPI).

[0024] In some optional implementation schemes, the deviation degree is divided into six levels: strong, relatively strong, medium, relatively weak, weak, and none. The deviation degree is determined based on the schedule performance index (SPI) and the cost execution index (CPI). The specific algorithm for the deviation degree is:

[0025] In some optional implementation schemes, the reasons for the analysis deviations are respectively ahead of schedule and cost overrun; ahead of schedule and cost savings; delayed schedule and cost overrun; delayed schedule and cost savings.

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] like Figure 1 As shown, a method for analyzing the aging of assembled anti-collision components based on BIM5D technology includes the following steps:

[0034] Step S100: Use modeling software to perform three-dimensional modeling on the construction project, and input the bill of quantities into the corresponding component type parameters;

[0035] Specifically, three-dimensional modeling is carried out based on the two-dimensional CAD drawings of the construction project, and the specific information in the project bill of quantities is input into the three-dimensional model of the modeling software, and the corresponding relevant parameters are given to its components, laying the foundation for the subsequent visualization model.

[0036] Specifically, step S100 has the following functions:

[0037] (1) Calculate the engineering quantity of drawings

[0038] Based on the drawings obtained from the engineering design, the basic model of the project is constructed to calculate the engineering quantity, and then the engineering quantity of each branch project and each specific business is summarized and calculated;

[0039] (2) Recalculate and analyze variables according to the drawings

[0040] Manual calculation of engineering quantities and quotations brings economic benefits to enterprises, mainly adjusting engineering quantities to save material costs. Therefore, it is necessary to use BIM technology to predict possible changes in engineering quantities. The specific operation is: first determine the total bid price based on similar projects or construction experience, calculate the materials required for the project, and compare the bid quantities;

[0041] (3) Optimize the preparation of construction plans

[0042] During the bidding process, BIM technology can be used to optimize the preparation of construction plans, improve the accuracy of engineering quantity calculations, reduce errors in engineering quantity quotations, and thus reduce operating risks;

[0043] (4) Optimize the preparation of construction plans

[0044] BIM technology can accurately, flexibly and quickly calculate the engineering quantity. Manual calculation of engineering quantity has a larger error than BIM technology calculation of engineering quantity. The common problem is calculation deviation. If this problem occurs, it is likely to determine that the quotation is unreasonable, resulting in misjudgment. The use of BIM technology can avoid these problems.

[0045] Step S200: using relevant software to compile construction project schedule information;

[0046] Specifically, relevant software is used to compile construction project schedule information into plans and bar charts, so as to allocate task resources, generate construction schedules, track progress, analyze engineering quantities and manage budgets.

[0047] Step S300: Integrate cost information and progress information using BIM5D technology, and analyze the time efficiency model of each task based on the WBS work breakdown structure and earned value method;

[0048] Specifically, the cost information includes basic items, contract budget cost, planned budget cost, and actual cost; the progress information includes planned progress and actual progress. The basic project information is based on the WBS work breakdown structure method to name the project number, formulate the project code, project name, and measurement unit. The contract budget cost information is the specific time of the project, the planned completed work volume (WS), and the contract unit price (CC). The contract budget cost is determined according to the relevant provisions of the construction contract. The planned budget cost is the specific time of the project, the planned completed work volume (WS), and the budget unit price (BC). The actual cost is the specific time of the project, the completed work volume (WP), and the actual unit price (AC). The actual cost is recorded and updated in real time by the construction site technicians. The planned progress is composed of the planned start time, the planned completion time, and the planned progress days. The actual progress is composed of the actual start time, the actual completion time, and the actual progress days.

[0049] Step S400: Providing real-time progress of the project and fund changes to project managers and construction technicians from different perspectives such as time dimension and project dimension;

[0050] Specifically, the time dimension module includes time interval, basic parameters, and evaluation indicators; the project dimension module includes project name, basic parameters, and evaluation indicators. The basic parameters include the planned cost of completed works (BCWP), the planned cost of completed works (BCWS), the actual cost of completed works (ACWP), the contract price of the construction company (CCWS), and the settlement price of the completed works of the construction company (CCWP). The evaluation indicators include schedule deviation (SV), cost deviation (CV), schedule performance index (SPI), and cost performance index (CPI).

[0051] Step S500: Evaluate the degree of deviation, analyze the cause of the deviation and propose corrective measures;

[0052] Specifically, the degree of deviation is divided into six levels: strong, relatively strong, medium, relatively weak, weak, and none. The degree of deviation is determined based on the schedule performance index (SPI) and the cost execution index (CPI).

[0053] The specific algorithm for the degree of deviation is:

[0054] Deviation analysis includes: schedule ahead of schedule, cost overrun; schedule ahead of schedule, cost savings; schedule delay, cost overrun; schedule delay, cost savings. Corrective measures include: appropriately reducing personnel and machinery, slowing down construction progress; improving the efficiency of personnel, materials and machinery construction; increasing personnel, materials and machinery configuration, speeding up construction progress, etc.

[0055] Step S600: predicting the progress-cost control problems that occur in the actual production of the project, and providing reliable early warnings for key tasks on key routes.

[0056] Furthermore, the time dimension and project dimension are used to provide the project management personnel and construction technicians with real-time progress of the project and changes in funds. Step S400 of the present invention also includes:

[0057] Step S410: Providing real-time progress of the project and fund changes to project managers and construction technicians through the time dimension;

[0058] Step S411: Summarize cost information and progress information based on the BIM5D construction project model and actual project construction information;

[0059] Step S412: The cost information includes: contract budget cost unit price (CC), planned budget cost unit price (BC), and actual cost unit price (AC); the progress information includes: planned progress (WS) and actual progress (WP);

[0061] Specifically, the construction enterprise contract price (CCWS) is automatically generated according to the contract budget cost unit price (CC) and the planned progress (WS); the construction enterprise completed project settlement price (CCWP) is automatically generated according to the contract budget cost unit price (CC) and the actual progress (WP); the planned cost of the proposed completed project (BCWS) is automatically generated according to the planned budget cost unit price (BC) and the planned progress (WS); the completed project planned cost (BCWP) is automatically generated according to the planned budget cost unit price (BC) and the actual progress (WP); the completed project actual cost (ACWP) is automatically generated according to the actual cost unit price (AC) and the actual progress (WP);

[0062] Step S414: the evaluation indicators are schedule variance (SV), cost variance (CV), schedule performance index (SPI), and cost performance index (CPI).

[0063] Specifically, the schedule variance (SV) and schedule performance index (SPI) are automatically generated based on the planned cost of work completed (BCWP) and the planned cost of work completed (BCWS); the cost variance (CV) and cost performance index (CPI) are automatically generated based on the planned cost of work completed (BCWP) and the actual cost of work completed (ACWP);

[0064] Furthermore, the time dimension and project dimension are used to provide the project management personnel and construction technicians with real-time progress of the project and changes in funds. Step S400 of the present invention also includes:

[0065] Step S420: Providing real-time progress of the project and fund changes to project managers and construction technicians through the project dimension;

[0066] Step S421: Summarize cost information and progress information based on the BIM5D construction project model and actual project construction information;

[0067] Step S422: The cost information includes: contract budget cost unit price (CC), planned budget cost unit price (BC), and actual cost unit price (AC); the progress information includes: planned progress (WS) and actual progress (WP);

[0068] Step S423: The basic parameters are the planned cost of completed work (BCWP), the planned cost of works to be completed (BCWS), the actual cost of completed works (ACWP), the contract price of the construction company (CCWS), and the settlement price of completed works of the construction company (CCWP).

[0069] Specifically, the construction enterprise contract price (CCWS) is automatically generated according to the contract budget cost unit price (CC) and the planned progress (WS); the construction enterprise completed project settlement price (CCWP) is automatically generated according to the contract budget cost unit price (CC) and the actual progress (WP); the planned cost of the proposed completed project (BCWS) is automatically generated according to the planned budget cost unit price (BC) and the planned progress (WS); the completed project planned cost (BCWP) is automatically generated according to the planned budget cost unit price (BC) and the actual progress (WP); the completed project actual cost (ACWP) is automatically generated according to the actual cost unit price (AC) and the actual progress (WP);

[0070] Step S424: the evaluation indicators are schedule variance (SV), cost variance (CV), schedule performance index (SPI), and cost performance index (CPI).

[0071] Specifically, the schedule deviation (SV) and schedule performance index (SPI) are automatically generated based on the planned cost of work performed (BCWP) and the planned cost of work to be completed (BCWS); the cost deviation (CV) and cost performance index (CPI) are automatically generated based on the planned cost of work completed (BCWP) and the actual cost of work completed (ACWP).
