Description

Technical Field

[0001] The present invention relates to the technical field of BIM technology, and in particular to a construction method for municipal engineering based on BIM technology. Background Art

[0002] With the continuous advancement of the urbanization process, the scale of municipal engineering construction projects has been increasing, and the types and quantities of underground facilities involved have become increasingly complex. In municipal engineering, the layout and maintenance of underground facilities such as pipelines and cables have always been important factors affecting project progress, safety, and economy. Traditional management methods for underground facilities usually rely on manual surveys, paper drawings, and simple calculation tools, which are prone to problems such as inaccurate information, lagging updates, or overlaps and omissions. These problems not only increase the complexity of construction but also pose great challenges to the maintenance and management in the later stage of the project.

[0003] During the construction process of municipal engineering, the spatial conflict between underground facilities and newly constructed structures is a common and serious problem. As the engineering design is gradually deepened, spatial conflicts may occur with existing underground facilities during the construction stage, resulting in delays in construction progress, increased additional costs, and even construction safety accidents. These conflicts are often due to the lack of effective information management means, resulting in the failure to fully consider the spatial distribution of underground facilities during the design stage, or the failure to detect and handle conflicts in a timely manner during the construction process, affecting the project quality and construction efficiency.
