Problems solved by technology

[0003] In the prior art, although there are some substation construction progress management methods, these methods are all customized solutions for a specific project. The scheme can only reflect the project itself, and there are many ground equipment and accessories in the substation site. The quality requirements for the construction process are also high. The existing substation construction progress management method cannot combine the actual substation construction situation to predict the problems in the substation construction. After understanding the root of the problem, organize an expert group to find a preliminary solution to the problem, and take measures to deal with the problem according to the plan. The period between the discovery of the problem and the solution to the problem takes up the time in the construction plan and prolongs the construction period. The construction period is not conducive to the timely advancement of the construction progress

Abstract

The invention discloses a construction progress prediction method and system based on a BIM model. The method comprises the steps of obtaining construction information so as to construct a triple-level model, and the triple-level model comprises a macro model, a meso model and a micro model; establishing a construction progress plan, and linking the construction progress and the triple-level model so as to generate four-dimensional progress simulation; according to four-dimensional progress simulation, building a construction task decomposition structure so as to formulate construction plans of different levels, according to the project content, adding construction tasks and progress plans step by step into the construction plan to form a four-dimensional construction simulation model; according to the four-dimensional construction simulation model, guiding the progress construction progress, displaying each work of the construction process in the visualized object building component virtual building process, adding the time dimension, and on the basis of real-time mathematical statistical analysis, simulating the problem in the construction process; from macroscopic to mesopic, and then microscopic substep modeling is performed, different-level models can be switched through clicking operations, and convenience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of substation construction management information technology, and more specifically, it relates to a method and system for predicting construction progress based on a BIM model. Background technique [0002] As an important part of the power system, the substation is an important hub connecting many remote areas or special operation areas. Due to its own particularity, the construction of the substation is different from the difficulty of ordinary building construction, and its construction efficiency is also higher than that of ordinary buildings. The construction efficiency of ordinary building construction is low, and the utilization rate of materials is low. Among them, 27% of the construction process needs to be reworked, 62% of the labor force is wasted, and 9% of the loss comes from the waste of materials. The construction progress management of substation construction projects is an important link i...
