Description

Technical Field

[0001] The present invention relates to the field of water conservancy construction project data processing, and in particular to a method and system for comparing the progress of water conservancy construction projects and dynamic early warning based on BIM. Background Art

[0002] With the continuous development of information technology in the field of construction projects, project management based on Building Information Modeling (BIM) has gradually become an important means to improve project management efficiency. By integrating data such as geometric information, time information, construction plans, and resource allocation of construction projects into a unified three-dimensional model, BIM technology provides technical support for the visualization and collaboration of project management.

[0003] However, traditional project management methods based on BIM technology still have the following deficiencies in dealing with progress comparison, deviation analysis, and dynamic early warning in complex projects:

[0004] Currently, most BIM-based project progress management methods mainly rely on manually input planned data and simple actual progress collection, lacking the ability to perform quasi-real-time comparative analysis on real-time progress data. Traditional methods often identify lags by statically comparing planned progress and actual progress, and are unable to dynamically track changes in deviations. Especially in large-scale water conservancy construction projects, the complex construction task breakdown structure and regional management requirements further increase the difficulty of progress analysis.

[0005] In the prior art, BIM-based project management methods mostly stay at progress lag marking or simple deviation statistics, lacking the ability of early warning based on dynamic data and being difficult to predict potential future deviation risks. For example, in water conservancy construction projects, the correlation between construction areas is relatively strong, and the progress delay of a certain task may have a chain reaction on the construction plans of other areas. Existing methods are unable to systematically analyze and early warn these potential risks. The optimization of resource allocation is insufficient, and resource allocation often relies on fixed construction plans and lacks the ability of dynamic adjustment. When progress deviations occur during construction, it is difficult for the prior art to optimize the resource allocation plan in real time in combination with the deviation analysis results. Summary of the Invention

[0006] The purpose of the present invention is to provide a method and system for comparing the progress of water conservancy construction projects and dynamic early warning based on BIM, which solves the above-mentioned technical problems pointed out in the prior art.

[0016] Accumulate and sum up the engineering quantities required for different components in all construction areas to obtain the overall verified engineering quantity.

[0017] The budget personnel can display specific engineering information such as the volume, area, and material consumption of this part by performing three-dimensional measurement on the model components of the required calculation area on the building model. The above processing operation improves the accuracy of engineering quantity calculation while reducing the workload of the calculation personnel, making the engineering quantity calculation more accurate and convenient.

[0018] Preferably, as an implementable solution; after performing the early warning processing on the project progress deviations of the construction areas in the digital management platform, it also includes:

Moreover, the platform can display relevant construction steps and the overlap and handover between processes in advance before the project starts through the construction engineering model, exposing potential hidden troubles that may occur during the connection of each process, so that management personnel can timely discover loopholes and construction management defects, and reduce the occurrence of rework, idling, and material loss.

[0032] Generate a process path set Pn based on the process dependency graph, where n represents the path number;

[0033] Perform topological sorting on each path to determine the process execution order and identify potential conflict points in the path;

[0034] Map the conflict points to the corresponding components and areas in the 3D BIM model; output the possible potential hazard points.

[0035] Preferably, as an implementable solution; output the possible potential hazard points, including the following steps:

[0036] According to the path conflict points in the process dependency graph G(V, E), determine the conflict point set {C1, C2,..., C m}, where C m represents the m-th conflict point; for each conflict point C m , based on the set of conflict attributes {A1, A2,..., A n} it involves, generate a hazard matrix H;

[0037] The dimension of the matrix H is m×n, and each element H m,n represents the hazard degree of the conflict point C m under the conflict attribute A n ; the specific calculation formula is:

[0038] where: Δ m,n represents the construction progress deviation of the conflict point C m on the conflict attribute A n ; δ n is the preset deviation threshold of the conflict attribute A n ; ω n is the weight coefficient of the conflict attribute A n ;

[0039] For each conflict point C m , based on the hazard degrees of each attribute in the hazard matrix, calculate the comprehensive hazard score R m , and its calculation formula is:

[0040] where N is the total number of conflict attributes;

[0062] Next, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0063] Next, the present invention will be further described in detail through specific embodiments in conjunction with the accompanying drawings.

[0064] As Figure 1 shown, the present invention provides a method for comparing the progress of water conservancy construction projects based on BIM and dynamic early warning, including the following operation steps:

[0065] S10. Construct a three-dimensional BIM model of the water conservancy construction project, and the three-dimensional BIM model includes the three-dimensional geometric information and components of the project;

[0066] S20. Divide the project into multiple construction areas according to the three-dimensional geometric information of the project to obtain multiple divided construction areas; add construction progress information to the components in the three-dimensional BIM model, including planned construction time and actual construction time;

[0067] S30. The digital management platform loads the three-dimensional BIM model and the data of the actual construction progress collected at the current moment; compares the actual construction progress with the planned construction progress through the digital management platform to identify the deviation of the project progress;

[0068] S40. Mark the construction area corresponding to the deviation in project progress in the 3D BIM model;

[0069] S50. Perform early warning processing for the project progress deviation of the construction area in the digital management platform.

[0070] Analysis of the above technical solution shows that: The present invention provides a method for comparing and dynamically warning the progress of water conservancy construction projects based on BIM. During initialization, a 3D BIM model of the water conservancy construction project is constructed. The 3D BIM model includes the 3D geometric information and components of the project. Then, according to the 3D geometric information of the project, multiple construction areas are divided to obtain multiple divided construction areas. Construction progress information, including planned construction time and actual construction time, is added to the components in the 3D BIM model. During specific operations, the digital management platform loads the 3D BIM model and the data of the actual construction progress collected at the current moment. The actual construction progress is compared with the planned construction progress through the digital management platform to identify project progress deviations. Finally, the construction area corresponding to the project progress deviation is marked in the 3D BIM model; and early warning processing for the project progress deviation of the construction area is performed in the digital management platform.

[0071] The above method for comparing and dynamically warning the progress of water conservancy construction projects based on BIM constructs a 3D BIM model, loads the model and real-time construction data through a digital management platform, compares the actual construction progress with the planned progress, marks the deviation area and performs dynamic early warning processing; at the same time, realizes the dynamic understanding and association of the construction progress, facilitating the real-time control of the project progress. At the same time, through the dynamic early warning function, the progress problems in the construction area can be discovered in time, facilitating the adoption of corrective measures and reducing the risk of construction delays.

[0072] As Figure 2 shown, before constructing the 3D BIM model of the water conservancy construction project, it also includes performing a processing operation for verifying the engineering quantity calculation:

[0073] S11. The digital management platform performs 1:1 loading based on the 3D geometric information of the project to obtain a building model;

[0074] S12. The budget personnel perform three-dimensional measurement settings on the components of the required construction area on the building model, including setting the volume, area, and material consumption per unit volume of the current component;

[0075] S13. Based on the volume, area, and material consumption per unit volume set by the measurement, calculate the engineering quantity required for the components in the current construction area;

[0076] S14. Cumulatively sum the engineering quantities required for different components in all construction areas to obtain the overall verified engineering quantity.

[0077] By performing three-dimensional measurement on the model components in the required calculation area on the building model, the above budget personnel can display specific engineering information such as the volume, area, and material usage of this part. The above processing operation improves the accuracy of the engineering quantity calculation while reducing the workload of the calculation personnel, making the engineering quantity calculation more accurate and convenient.

[0078] For the technical solution of this embodiment, the above operation constructs a three-dimensional BIM model of a water conservancy construction project. In the specific implementation process, three-dimensional BIM model components can be constructed according to the design drawings; and detailed attribute information such as engineering time, completion time, and acceptance situation is added to each three-dimensional BIM model component; at the same time, a database is established to store and manage all three-dimensional BIM model components and their related attribute information. This establishes a technical foundation for the subsequent progress comparison analysis and early warning of the water conservancy construction project executing the above three-dimensional BIM model.

[0079] At the same time, the above processing operation of executing the verification of the engineering quantity calculation not only improves the accuracy of the engineering quantity calculation, reduces manual errors, and reduces the workload of the calculation personnel, making the calculation process more efficient and convenient. At the same time, it also provides accurate basic engineering quantity data for the subsequent construction progress management to ensure the rationality of the construction plan.

[0080] Water conservancy engineering projects often have a large project volume and complex and changeable construction environments, resulting in huge and cumbersome engineering quantity verification for budget personnel. The above solution uses BIM technology to achieve a 1:1 construction of engineering information data. The budget personnel perform three-dimensional measurement on the model components in the required calculation area on the building model to calculate the engineering quantity required for the components in the current construction area. This not only improves the accuracy of the engineering quantity calculation while reducing the workload of the calculation personnel, making the engineering quantity calculation more accurate and convenient.

[0081] Such as Figure 3 shown, after performing the engineering progress deviation early warning processing on the construction area in the digital management platform, it further includes:

[0082] S61. The digital management platform loads the three-dimensional BIM model and sets a preset construction progress for each component according to the construction plan; the construction plan includes construction procedures;

[0083] S62. Obtain the instruction for interspersed construction procedures for the current construction plan input by the current management personnel; before the project starts, analyze the abnormal situations of the interspersed construction procedures of the adjusted construction plan in advance;

[0084] Analyze the interspersed situation between processes in advance based on the construction plan, and then analyze and output potential hidden trouble points. Moreover, the platform can display relevant construction steps and the interspersed situation between processes in advance before the project starts through the construction engineering model, find out potential hidden trouble and abnormal situations, so that managers can timely discover loopholes and construction management defects, and reduce the occurrence of rework, idling and material loss.

[0085] As Figure 4 shown, after comparing the actual construction progress with the planned construction progress through the digital management platform and identifying the deviation of the project progress, it further includes determining the deviation level for the current deviation data, including the following operation steps:

[0086] S31. Compare the planned progress data with the actual progress data to generate deviation data;

[0087] S32. Map the deviation data to the component attribute set of the 3D BIM model and update the usage status information of the components;

[0088] S33. Compare the deviation data with the preset deviation threshold range to generate a deviation level; generate a progress comparison report according to the deviation level.

[0089] The technical solution of this embodiment can generate deviation data through steps S31 - S33, map it to the BIM model, determine the deviation level and output a report; in this way, the construction progress deviation can be accurately quantified to help managers quickly locate problems. Through the deviation level classification, the problem areas to be solved first are clarified, improving management efficiency.

[0090] As Figure 5 shown, comparing the actual construction progress with the planned construction progress through the digital management platform specifically includes:

[0091] S311. Preset the synchronization frequency and the corresponding time interval;

[0092] S312. Automatically synchronize the actual progress with the 3D BIM model at the predetermined time interval; use data encryption technology to protect the data of the actual construction progress during the transmission process;

[0093] S313. Ensure the accuracy of the synchronized data through the timestamp alignment method.

[0094] The technical solution of this embodiment can set the synchronization frequency and time interval, and ensure data accuracy through data encryption and timestamp alignment. Timestamp alignment ensures the real-time and accuracy of the data, providing a reliable basis for progress comparison.

[0095] Preferably, as an implementable solution; analyze the abnormal situations of the interleaved construction processes in the adjusted construction plan and output the potential hidden trouble points, including the following steps:

[0096] S621. Extract the logical relationships between processes and generate a process dependency graph G(V, E), where V represents process nodes and E represents process dependency relationships;

[0097] S622. Generate a process path set Pn based on the process dependency graph, where n represents the path number;

[0098] S623. Perform topological sorting on each path to determine the process execution order and identify the possible conflict points in the path;

[0099] S624. Map the conflict points to the corresponding components and regions in the 3D BIM model; output the potential hidden trouble points.

[0100] Preferably, as an implementable solution; output the potential hidden trouble points, including the following steps:

[0101] S6241. According to the conflict points of each path in the process dependency graph G(V, E), determine the conflict point set {C1, C2, …, C m}, where C m represents the m-th conflict point; for each conflict point C m , based on the set of conflict attributes {A1, A2, …, A n} (where A n represents the n-th conflict attribute, such as construction schedule deviation or resource allocation deviation, etc.), generate a hidden trouble matrix H;

[0102] The dimension of the matrix H is m×n, and each element H m,n represents the hidden trouble degree of the conflict point C m under the conflict attribute A n ; the specific calculation formula is:

[0103] Where: Δ m,n represents the construction schedule deviation amount of the conflict point C m on the conflict attribute A n (for example, the difference between the planned construction time and the actual construction time); δ n is the preset deviation threshold of the conflict attribute A n for normalization processing; ω n is the weight coefficient of the conflict attribute A n to reflect the importance of this attribute to the overall hidden trouble;

[0104] S6242. For each conflict point C m, calculate the comprehensive hidden danger score R based on the hidden danger levels of each attribute in the hidden danger matrix m , and its calculation formula is:

[0105] where N is the total number of conflicting attributes;

[0106] S6243. According to the comprehensive hidden danger score R m compare it with the preset hidden danger level boundary values T1 and T2, and determine the hidden danger level L for each conflict point C m ; m ;

[0107] The specific determination formula is:

[0108] S6244. Map the above-mentioned hidden danger matrix H and the hidden danger levels L of each conflict point m to the corresponding components and construction areas in the 3D BIM model to achieve dynamic early warning processing and visual display of potential hidden danger points.

[0109] Preferably, as an implementable solution; generate dynamic early warning information based on deviation data, including the following steps: classify the project risks according to the output dynamic early warning information: comprehensive hidden danger score R m <0.3: Set as low risk; 0.3 ≤ comprehensive hidden danger score R m <0.7: Set as medium risk; comprehensive hidden danger score R m ≥0.7: Set as high risk; bind the dynamic early warning information to the 3D BIM model and display it in real time in the form of colors, symbols, etc. At the same time, by referring to Figure 6 , it can be known the unfinished areas, the overdue completed areas and the unstarted areas of the output, and they can be displayed in different colors for convenient overall understanding of the construction progress.
