Construction and Application of a Refined Management Smart Information Repository Based on BIM Technology

Abstract

Data from the China Construction Industry Association in 2023 shows that over 60% of large construction enterprises nationwide have deployed smart construction site systems. However, the industry faces challenges such as high-cost constraints and uneven regional development. This paper constructs a smart information repository comprising six sub-repositories: BIM, Personnel, Materials, Quality, Equipment, and Environment. It achieves digital management throughout the entire construction lifecycle through technological integration. Case validation demonstrates that this system can reduce construction costs by 18%-25%, shorten construction periods by 13%, and provides an innovative pathway for the development of smart construction sites.
