Problems solved by technology

[0003] In addition, after establishing WBS nodes according to the decomposed tasks, it is necessary to attach labor, materials, machinery and other consumption resources to each WBS node, and it is necessary to calculate the engineering quantity consumed by these resources and the cost of each WBS node. All these tasks It's all very cumbersome and a huge workload
Especially after splitting nodes, hooking resources and various data, and changing projects, it is necessary to recalculate and update the various data involved in the changed parts, and project changes will occur frequently, and this repetitive workload is unbearable
[0004] The existing technology is basically in the state of manually establishing WBS nodes, or only using software to establish construction schedules. All content still needs to be judged and processed by the human brain, and the workload of the staff is still heavy.

Embodiment 1

[0042] Figure 1a It is a flow chart of the method for automatically generating WBS nodes based on the BIM model described in Embodiment 1 of the present invention, as shown in Figure 1a As shown, the method includes:

[0043] 110: Define tasks in terms of construction works.

[0044] Specifically, the specific tasks in the building construction process of the task, such as building walls, supporting formwork, pouring concrete, etc.

[0045] 120: Associate the corresponding bill of quantities content for the task according to all the bill of quantities contents included in the construction project.

[0046] Specifically, the content of the bill of quantities is also called a checklist. In the entire construction project, one task may be associated with multiple bills of quantities. For example, when the task is to build a wall, its associated bill of quantities May include: building straight walls, building curved walls, etc. In addition, when the process of a bill of quant...

Embodiment 2

[0067] This embodiment is described based on Embodiment 1, as figure 2 As shown, the difference between the method described in this embodiment and the method described in embodiment 1 is only:

[0068] The step 130 also includes: according to the BIM model, determining the model range contained in the pipeline section, and the model scope corresponds to the component graphics in the bill of quantities contained in the pipeline section (corresponding to figure 2 in step 130').

[0069] After step 160, the method may also include:

[0070] 210: Associating the component graphic elements in the content of the bill of quantities corresponding to the WBS node to the WBS node.

[0071] Specifically, the BIM model also includes component graphics corresponding to the content of each bill of quantities. After the content of the bill of quantities corresponding to the WBS node is determined, through this step, the corresponding component graphics are automatically associated with ...

Embodiment 3

[0076] image 3 It is a schematic diagram of the system module structure for automatically generating WBS nodes based on the BIM model described in Embodiment 3 of the present invention, as shown in image 3 As shown, the system 300 includes: a task definition unit 310 , a task association unit 320 , a pipeline segment unit 330 , a node establishment unit 340 , a corresponding unit 350 and a calculation unit 360 .

[0077] The task definition unit 310 is configured to define tasks according to construction projects.

[0078] The task associating unit 320 is configured to associate the corresponding bill of quantities content with the task according to all the bill of quantities contents included in the construction project.

[0079] The flow section unit 330 is used to divide the flow section of the construction project according to the BIM model, and determine the content of the bill of quantities included in the flow section, and the content of the bill of quantities corres...

Abstract

The invention discloses a method and a system for automatically generating a WBS (Work Breakdown Structure) node basing on BIM (Building Information Modeling), which belongs to the field of a computer. The method comprises the steps of defining a task according to building engineering; relating corresponding BOQ (Bill Of Quantity) content to all BOQ contents contained by the building engineering; dividing a pipelining segment for the building engineering according to BIM, and determining BOQ content contained by the pipelining segment, wherein the BOQ content corresponds to corresponding consumed resource, corresponding quantity and corresponding cost; carrying out intersection operation on the BOQ content related to the task and the BOQ content contained by the pipelining segment, obtaining an intersection and establishing the WBS node when the intersection is not null; calculating the BOQ content in the intersection corresponding to the WBS node; and calculating the consumed resource, the quantity and the cost of the WBS node according to BIM and the BOQ content corresponding to the WBS node. According to the method and the system, which are disclosed by the invention, the working quantity of a worker is reduced, and the working efficiency is increased.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and system for automatically generating WBS (Work Breakdown Structure) nodes based on a BIM (Building Information Modeling) model. Background technique [0002] In the process of building construction, the tasks are generally decomposed by WBS according to the flow section. The method of decomposition is generally according to the dimensions of the floor and flow section, such as the concrete pouring of beams and slabs. Generally, it will be decomposed according to the dimensions of the floor and flow section into concrete pouring of 1 floor and 1 section of beam and slab, and 1 floor of 2 sections of beam and slab. Concrete pouring, concrete pouring of 3-section beams and slabs on the 1st floor, concrete pouring of 4-section beams and slabs on the 1st floor, concrete pouring of 5-section beams and slabs on the 1st floor; concrete pouring of 1-section beams and...
