Abstract
Building information modeling (BIM) is an emerging technology that can effectively solve the problems of information dispersion, complex personnel management, and lack of construction supervision, which often occur during the construction of tunnel engineering. Taking the construction of Haicang Tunnel in Xiamen, China as a case study, the utilization of BIM technology in the design stage, the construction simulation and operation are demonstrated during the full-life cycle of the project. During the construction of Haicang Tunnel, the technologies of BIM 3D, BIM 4D, BIM 5D, and Cloud Platform are used to make the construction process controllable and to facilitate the implementation and deployment of construction plans. BIM 3D is a visualization method to show the detailed model in the construction. The design is optimized by the navigation collision function of BIM 3D. BIM 4D adds the time schedule into BIM 3D model to show the construction schedule. BIM 5D adds the cost into BIM 4D model to show the construction consumption. The methods of BIM 4D and BIM 5D can assist the engineering management in allocating resources and funds in the project. Cloud Platform is used to effectively implement information management.
Highlights
Building information modeling (BIM) technology has the characteristics of visualization, simulation, optimization, and collaborative informatization, which can improve the level of engineering construction management especially with higher construction requirements
In the case study of the Haicang Tunnel construction described in this paper, different functions of BIM technology are applied in different stages of the construction to optimize the management of the construction of the project
BIM technology is based on 3D modeling and can be applied over the full-life cycle of the project
Summary
BIM technology has the characteristics of visualization, simulation, optimization, and collaborative informatization, which can improve the level of engineering construction management especially with higher construction requirements. BIM is an engineering data model based on 3D digital technology that integrates all kinds of relevant information for construction projects and provides a digital expression of the entity and functional characteristics of engineering project facilities (Eastman et al, 2011). The construction period of a tunnel project is relatively long due to complex geological conditions and multiple projects’ information so that the level of management determines the quality of construction. The function of engineering information integration can make it easy to implement many operations that are difficult to complete in later stages, such as the refinement of model design, safety of the structure, and system operation (Ryu et al, 2015).
