Abstract
The topic of Building Information Modelling (BIM) adoption by public organizations has become a central subject of research, and a significant amount of BIM documents, guidelines, and standards have been created to meet different organizational purposes. Compared to the building industry, the application of BIM tools for tunnel project management is lagging far behind. This paper proposes a methodology for integrating BIM tools for conventional tunnelling. A fundamental distinction is made between the tunnel internal architectural domain and the external structural domain. For the former, BIM methodology can be applied similarly to the building industry. For the latter, it is suggested that a BIM model be built according to the essential information generated during tunnelling excavation. The proposed methodology was put to test for an actual tunneling project. A routine was established where the supervisor on behalf of the owner was responsible for gathering and reporting essential data in tabular form. Via REVIT's Application Programming Interface (API), a code was developed so that a BIM model was built and updated automatic to data insertion. Ultimately, the final BIM model allows managing up-to-date qualitative and quantitative information visually. Thus, human understanding and interpretation are enhanced for future uses, such as maintenance, future renovations and project post-analysis.
Highlights
Building Information Modelling (BIM) is defined as a shared digital representation of a built asset to facilitate design, construction, and operation processes to form a reliable basis for decisions (ISO 19650/1)
Public construction procurement agencies are increasingly demanding the use of BIM, and the topic of BIM adoption has become a central subject of research in the field of construction management (Gurevich and Sacks, 2020)
It is clear that the adoption of BIM for New Austrian Tunnelling Method (NATM) projects is not a straightforward process and that any proposed methodology must consider the distinction between tunnel Architectural domain' (AD) and Structural domain' (SD)
Summary
BIM is defined as a shared digital representation of a built asset to facilitate design, construction, and operation processes to form a reliable basis for decisions (ISO 19650/1). Public construction procurement agencies are increasingly demanding the use of BIM, and the topic of BIM adoption has become a central subject of research in the field of construction management (Gurevich and Sacks, 2020). For this purpose, a significant amount of BIM documents, guidelines, and standards have been created by different construction organizations (Chae & Kang, 2015; Cheng & Lu, 2015). Zhou et al (2017) conducted a systematic study of projects to analyse BIM applications in China's tunnel engineering industry There, they found that the application of BIM technology for tunnel engineering is limited and mainly applied during the design stage rather than during the construction and operation stages. The methodology proposed by the authors, as well as the implementation process and lessons learned throughout, are discussed in detail
