Research on Key Technologies of Construction Management of Large Swivel Bridge Based on BIM Technology——A Case Study of Dade Swivel Bridge

Abstract

Swivel bridge is a special construction method in bridge engineering. It has the characteristics of difficult construction, complex environment and many benefits. The project needs fine management to overcome various problems in traditional construction management mode. Taking Kunchu Expressway over Chengdu-Kunming Railway Bridge as an example, this paper introduces the technical route and technical application points of fine management of construction of turning bridge of Expressway based on BIM technology. The main application points of this paper include: BIM collaboration, BIM collision detection, BIM project management application platform, UAV three-dimensional scene modeling, three-dimensional laser scanning. Practice has proved that BIM technology has incomparable advantages over traditional management mode in finding drawings errors, technical submission, engineering statistics, collision detection, information integration and so on. The implementation of BIM technology has brought enormous technical and economic benefits to project management and has good prospects for promotion.
