Description

Technical Field

[0001] The present invention belongs to the technical field of model engineering quantity calculation methods, and specifically is an engineering quantity application method of BIM technology for large-scale booster pump stations. Background Art

[0002] Quantity calculation is the core content of cost estimation work, which takes up about half of the cost estimation personnel's working time. The main reason is that the two-dimensional plane drawings cannot directly extract the engineering quantities of the project construction, and it is necessary to manually re-measure, calculate and count according to the drawings. In addition, in order to ensure the precision and accuracy of the engineering quantity calculation structure, the design and review personnel need to spend a lot of time reading the drawings, calculating and summarizing.

[0003] BIM (Building Information Modeling) technology developed in recent years is based on building information modeling and building information modeling. As a complete information model, BIM can connect data, processes and resources at different stages of the project life cycle. Through the virtual and real combination of BIM model and actual project progress, it can make full use of BIM technology in cost-effective design scheme comparison, automatic calculation of project quantities, accurate acquisition of progress project quantities and other functions.

[0004] In the existing technology, BIM software has the function of calculating engineering quantities, but the content of the engineering quantity tables it outputs is rather messy. The export formats of the engineering quantity tables statistically generated by different BIM software are also different, and they cannot be directly read by engineering pricing software such as Glodon, resulting in the separation of quantity calculation and pricing, and the value of BIM software is not truly brought into play. Summary of the invention

[0005] The purpose of the present invention is to provide a method for applying the engineering quantity of BIM technology in a large-scale booster pump station to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a method for applying the engineering quantity of BIM technology to a large-scale booster pump station, comprising:

[0007] 1) Select multiple survey points in the survey site and perform coordinate processing on the survey points in the survey site;

[0008] 2) Import the coordinates into the system and complete the coordinate entry;

[0009] 3) Read the coordinate values ​​to form a modifiable hard point table;

[0010] 4) Build BIM 3D model;

[0013] 7) Conduct collision check on the BIM 3D model based on the actual project situation;

[0014] 8) Adjust the BIM 3D model based on the collision check results;

[0015] 9) Design the deduction rules for engineering quantity calculation according to the specification requirements;

[0016] 10) Modify the BIM 3D model according to the engineering quantity calculation deduction rules to form a BIM quantity calculation model that can be used for quantity calculation;

[0017] 11) The BIM quantity calculation model loads the attribute list and the coding list and performs coding correspondence. According to the quantity calculation rules, the entire project quantity is obtained through calculation and summary. The parameters are filtered according to the attribute list after coding, and the required quantity table is exported.

[0018] Preferably, all parametric components in the BIM three-dimensional model are created through hierarchical modeling.

[0019] Preferably, the BIM three-dimensional model is dynamically managed; and the measure items are drawn in the BIM three-dimensional model according to the project progress.

[0020] Preferably, the proofreading includes proofreading the accuracy of the component built-in information and proofreading the integrity of the component built-in information.

[0022] The purpose of the present invention is to provide a method for applying BIM technology to engineering quantities in large-scale booster pump stations, so as to realize automatic matching and association between model components and engineering quantity lists, which can not only save quantity calculation time and reduce repeated quantity calculations, but also improve the work efficiency and accuracy in the bidding stage and the measurement and pricing stage after quality inspection and evaluation, reduce the workload of cost personnel, and promote the informatization and automation of engineering cost management.
