Description

Technical Field

[0001] The present invention relates to the technical field of construction management, and in particular to a construction project management method, equipment and storage medium based on BIM modeling. Background Art

[0002] Construction project management refers to the management of the entire process of planning, organizing, arranging, directing, managing, supervising, controlling and coordinating construction projects by construction units in the process of completing the undertaken engineering construction projects, using systematic viewpoints and theories as well as modern scientific and technological means; construction project management mainly includes: construction preparation stage, construction stage, completion acceptance stage, and quality assurance and after-sales service stage.

[0003] Existing methods for construction project management usually monitor the construction site and the construction process by using modules such as construction progress tracking, construction personnel tracking, construction material tracking, construction site environment detection, and construction site safety monitoring, and perform real-time control based on the data obtained from the supervision. Although this improved method can monitor the construction project in real time, when there are many construction projects being executed at the same time on the construction site, resulting in conflicts in the space occupied by the construction projects, this improved method can only monitor after the conflict occurs, and cannot effectively predict the time and location of the conflict, resulting in the construction project interfering with the normal construction process due to the conflict in occupying space, thereby affecting the overall construction efficiency. For example, in the public number Patent application CN117649317A discloses a construction project platform management method and system. The solution is to monitor the construction progress, the amount of construction materials and the construction personnel in real time, and at the same time realize a green construction environment, thereby ensuring the smooth and orderly operation of the project construction. Other improvements in construction project management are usually improvements in construction coordination and construction personnel management. This improvement method still cannot effectively predict the time and location of conflicts in construction projects, resulting in the construction project being disturbed by the conflict of land occupation, thereby affecting the overall construction efficiency. In view of this, it is necessary to improve the existing methods for construction project management. Summary of the invention

[0060] Step S2, based on the construction equipment and construction materials, obtain the construction restriction space corresponding to each construction project in the spatial coordinate system, analyze the construction restriction space, and obtain the construction conflict space based on the analysis result; Step S2 includes: Step S201, for any construction project and the project equipment XB1 to project equipment XB used to complete the construction project j ; For any project device XB j1, set the project device XB j1 The position in the construction analysis coordinate system is recorded as the equipment position SW j1 ; When the construction project is completed, the project equipment XB j1 The construction materials used are recorded as equipment materials SC, and the positions of all equipment materials in the construction analysis coordinate system are recorded as material positions CW; for any material position CW, the material position CW is marked to the equipment position SW in the construction analysis coordinate system based on the construction planning data j1 The shortest path is recorded as the material transportation path;

[0061] In the specific implementation process, obtaining the material transportation path will help to obtain the conflicting paths between construction projects in the subsequent analysis, so that in the actual construction, analysis can be performed based on the conflicting paths and construction adjustments can be made to prevent conflicts in material transportation paths during the actual construction, which will affect the overall construction progress.

[0062] Step S202, obtain the material transportation paths corresponding to all equipment materials SC, and store all material positions SC, all material transportation paths and equipment positions SW j1 Recorded as project equipment XB j1 Equipment restricted area; record the equipment restricted area of ​​all project equipment XB as the construction restricted space of the construction project;

[0063] Step S203, obtaining the construction restricted space of all construction projects;

[0064] Step S204, for any two construction projects α1 and α2, the construction restriction space β1 and the construction restriction space β2 of the construction project α1 and the construction project α2 are simultaneously placed in the construction analysis coordinate system;

[0065] Step S205, when the construction restriction space β1 and the construction project β2 do not have an intersection, the construction project α1 and the construction project α2 are recorded as non-intersecting projects; when the construction restriction space β1 and the construction restriction space β2 have an intersection and only the material position SC exists in the intersection area, the construction project α1 and the construction project α2 are recorded as non-intersecting projects, wherein the construction conflict space of the non-intersecting projects is recorded as non-existent;

[0066] In the specific implementation process, for example, the construction restricted spaces corresponding to the mixing of mud and sand and the construction of steel bars in the construction project of this embodiment are respectively as follows: Figure 3As shown in TT1 and TT2 in, SW1 is the location of the cement truck, SW2 is the location of the silt truck and the concrete mixer, SW3 is the location of the steel bar straightening machine and the steel bar cutting machine, SW4 is the location of the steel bar truck, and the path between SW1 and SW3 is the path of the cement truck in the process of building the steel bar, the path between SW1 and SW2 is the path of the silt truck in the process of mixing silt, and the path between SW3 and SW4 is the path of the steel bar truck in the process of building the steel bar; through analysis, it can be obtained that the area where WW1 and SW1 are located is the intersection of the construction space TT1 and the construction space TT2, then mixing silt and building steel bars are recorded as full intersection projects, and the location SW1 of the cement truck and the path WW1 are recorded as construction conflict space;

[0067] Step S206, when the construction restricted space β1 and the construction restricted space β2 intersect, a material transportation path exists in the intersection area, and there is no equipment position SW in the intersection area, the construction project α1 and the construction project α2 are recorded as path intersection projects, and the material transportation path in the intersection area is recorded as a construction conflict space;

[0068] Step S207, when the construction restricted space β1 and the construction restricted space β2 intersect, there is a device position SW in the intersection area, and there is no transportation material path in the intersection area, the construction project α1 and the construction project α2 are recorded as equipment intersection projects, and the device position SW in the intersection area is recorded as a construction conflict space;

[0069] Step S208, when the construction restricted space β1 and the construction restricted space β2 intersect and there are equipment positions SW and material transportation paths in the intersection area, the construction project α1 and the construction project α2 are recorded as full intersection projects, and the equipment positions SW and material transportation paths in the intersection area are recorded as construction conflict space;

[0070] Step S209: Analyze each construction project with all other construction projects, and obtain corresponding construction conflict spaces.

[0071] Step S3, establishing a planning timeline based on the construction planning data, and analyzing the progress of each construction project in the spatial coordinate system based on the planning timeline; analyzing the construction conflict space, obtaining the conflict time based on the analysis results and making construction adjustments; Step S3 includes:

[0072] Step S301, for any construction plan in the construction planning data, a planning time axis is established, wherein the starting point of the planning time axis is the time when construction starts in the construction plan, and the end point of the planning time axis is the time when construction ends in the construction plan;

[0073] Step S302: record all construction projects used for construction planning as planning projects GX1 to GX n ; The construction time of all planning projects GX in the construction plan is marked as planning period GS1 to planning period GS in the planning timeline. n ;

[0074] Step S303: for any planning project GX n1 , will be combined with the planning period GS n1 The planning project corresponding to the planning period GS with an intersection is recorded as planning project GX n1 The items to be screened and analyzed; when the items to be screened and analyzed are the same as the planned items GX n1 If there are no overlapping projects, no adjustment will be made to the construction. n1 If not all of them are non-intersecting projects, they will be combined with the planned project GX n1 The analysis items to be screened that are not non-intersection items are recorded as conflict analysis items;

[0075] Step S304: for any conflict analysis item, record the planning period GS of the conflict analysis item as the conflict period; when the conflict analysis item and the planning item are path intersection items, record the planning item GX n1 The time for transporting materials to the construction conflict space is in the planning period GS n1 In the conflict analysis project, the time for transporting materials to the construction conflict space is recorded as the conflict path time in the conflict period; when the project path time and the conflict path time overlap, the project path time is recorded as the conflict time; when the project path time and the conflict path time do not overlap, no conflict time is set;

[0076] In the specific implementation process, in the analysis of this embodiment, mixing mud and building steel bars are conflict analysis projects and are full intersection projects. For the planning project mixing mud and building steel bars, Figure 2The construction time axis DD2 of the steel bar construction is recorded as the conflict period; through analysis, it can be obtained that for the construction conflict space WW1: the time when the silt transport truck drives to WW1 in the silt mixing is 14:10, and the time when the steel bar transport truck drives to WW1 in the steel bar construction is 14:25, then the project path time and the conflict path time do not overlap, and no conflict time is set; for the construction conflict space SW1: the cement transport truck is used at 14:10 and 14:30 in the silt mixing, and the cement transport truck is used at 14:30 in the steel bar construction. At 14:30, the same cement transport truck is used by two construction projects at the same time, that is, the project equipment time and the conflict equipment time overlap. In order to ensure that both construction projects can be implemented smoothly, 14:30 should be recorded as the conflict time, and the conflict time should be reported to the staff, so as to adjust the time when the cement transport truck is used in the two construction projects to prevent the conflict of the use of cement transport trucks from interfering with the normal construction process, thereby affecting the overall construction efficiency;

[0077] Step S305: When the conflict analysis project and the planning project are equipment intersection projects, the project equipment XB corresponding to the equipment position SW recorded as the construction conflict space is recorded as the equipment to be screened; based on the planning project GX n1 The usage time of the equipment to be screened is in the planning period GS n1 The use time of the equipment to be screened based on the conflict analysis project is recorded as the conflict equipment time in the conflict period. When the project equipment time and the conflict equipment time overlap, the overlapping time node or time period is recorded as the conflict time, and the conflict time is set; when the project equipment time and the conflict equipment time do not overlap, the conflict time is not set;

[0078] Step S306, when the conflict analysis item and the planning item are full intersection items, based on the analysis method when the conflict analysis item and the planning item are path intersection items and when the conflict analysis item and the planning item are path intersection items, obtaining the conflict time;

[0079] Step S307: when the conflicting time is obtained, the planning project GX n1 The process at the conflict time and the process of the conflict analysis project at the conflict time are recorded as the planning conflict process and the analysis conflict process; for any conflicting process in the planning conflict process and the analysis conflict process, the other processes of the planning project GX where the conflicting process is located are recorded as the to-be-associated processes DG1 to the to-be-associated processes DG g , for any process DG to be associated g1 , when the equipment material SC or project equipment XB used in the conflicting process is associated with the process to be associated DG g1 If the equipment material SC or project equipment XB in the same, the process DG to be associatedg1 Recorded as a weakly associated process of the conflicting process; when the equipment material SC and project equipment XB used in the conflicting process are g1 If the equipment material SC and project equipment XB are the same, the process to be associated DG g1 Recorded as a strongly associated process of the conflicting process;

[0080] In the specific implementation process, for example, in a data processing, the planning conflict process and the analysis conflict process are mixing mud and building steel bars, and the conflict time is 14:30; the process of mixing mud at 14:30 is transporting cement, and all the processes DG to be associated with mixing mud are transporting mud and mixing mud, among which, the equipment materials SC and project equipment XB used for transporting cement are cement and cement transport truck, the equipment materials SC and project equipment XB used for transporting mud are mud and mud transport truck, and the equipment materials SC and project equipment XB used for mixing mud are concrete mixer, mud and cement; then mixing mud can be recorded as a weakly associated process of the conflicting process transporting cement; by obtaining the weakly associated process and the strongly associated process of the conflicting process, the correlation between the conflicting process and other processes can be obtained. For the conflicting process with weak correlation with other processes, the process can be adjusted relatively easily to prevent the adjustment of the process from affecting other processes in the project;
