Building engineering project cost evaluation management method and device based on BIM building model, and storage medium

Abstract

The invention discloses a BIM building model-based construction engineering project cost evaluation management method and device and a storage medium, and the method comprises the steps: obtaining each BIM building model designed in a prefabricated construction engineering project, screening building materials of various properties needed by the construction of each second-level sub-region in each first-level region in each BIM building model, and carrying out the construction of each second-level sub-region in each second-level sub-region in each BIM building model; meanwhile, the set use material volume of each second-level sub-region in each first-level region in each BIM building model is obtained, the unit volume use amount of each property building material required by construction of each second-level sub-region in each first-level region in each BIM building model is obtained, and the actual use material cost of each second-level sub-region in each first-level region in each BIM building model is analyzed; and the estimated comprehensive cost of each BIM building model in the fabricated building engineering project is calculated, and the BIM building model with the lowest comprehensive cost is screened for project construction, so that the fabricated building engineering cost assessment level is improved, and the rationality and scientificity of engineering cost assessment are ensured.

Description

technical field [0001] The invention relates to the field of construction project cost evaluation, and relates to a construction project cost evaluation management method, equipment and storage medium based on a BIM building model. Background technique [0002] With the gradual promotion of BIM technology in construction engineering, more and more construction units have begun to use this technology, and it has become the development trend of building informationization. Adding the BIM model to the prefabricated construction project to assist in the management of the project cost can make the data statistics more intuitive and convenient. [0003] At present, the existing prefabricated construction project cost evaluation methods generally have the following deficiencies: [0004] 1. The existing prefabricated construction project cost evaluation method basically adopts personnel evaluation, that is, the cost personnel carry out the project cost according to the architectur...

Problems solved by technology

[0004] 1. The existing prefabricated construction project cost evaluation method basically adopts personnel evaluation, that is, the cost personnel carry out the project cost according to the architectural drawing data, which not only leads to a large workload of the cost personnel's evaluation, but also occupies a lot of working time and energy of the cost personnel. Moreover, there is a problem that the cost evaluation error of the prefabricated construction project is relatively large, thereby reducing the cost evaluation level of the prefabricated construction project;

[0005] 2. The existing cost evaluation methods of prefabricated construction projects are all based on the unit price of the same type of construction materials. There is a problem that some basic functional areas in the building have different requirements for material properties, which leads to accurate cost evaluation of prefabricated construction projects. The degree is reduced, which affects the rationality and scientificity of the cost evaluation of prefabricated construction projects;
