BIM experience in infrastructural large projects: Doha Metro--Al Jadeda Station al Matar B case study

摘要

Civil engineers and architects typically outline projects and construction data using technical drawings. At the beginning of the XXI Century, the development of new modeling technologies has led to introduction of a new intelligent approach to 3D design: the Building Information Modeling (BIM). BIM enables to improve the planning, design, construction and management of infrastructure or buildings for the entire life cycle. 3TI is involved in Doha Metro Red Line South Underground main stations project, as consultant in architectural finishes and MEP works of Al Jadeda Station al Matar B. BIM process has been efficiently applied. This paper wants to underline that all project phases have been studied using this new technology, from the analysis of the two-dimensional drawing, through the construction of a 3D model, achieving an high detailed level for every single designed part. All specialists involved in the project have the knowledge of the process and have to manage their updating in order to reach a global understanding. Design coordination is the responsibility of all parties (meant as specialists of different sectors) as an ongoing process until the completion: the outputs are not simple representations but a set of information. Definitely, this paper discusses the importance of BIM technology in Civil Engineering and Architectural sectors, as an important mean for the time optimization compared to the traditional approach and the reduction of costs, thanks to the prevision and the resolution of the issues, during the planning through the interface checking. The analysis of the case of study highlights as the coherence of BIM procedure application enables to adopt a maintenance strategy leading to a longer life-cycle of Al Jadeda Station.
