Factor analysis of interface problems among construction parties - A case study of MRT

Abstract

With the rapid development of technology and the increasingly bigger size of constructions, the involved parties are required to pay more attention to all types of difficult interface problems than ever before. By considering the mass rapid transit system (MRTS) as an example, several problems resulting from complicated mechanical, electrical, civil, and track interfaces led to enormously extra losses in the construction process. Accordingly, this paper intends to use quantitative methods to categorize a variety of interface problems in the MRTS construction projects as well as identify their individual impacts in order to clarify these interface problems. The analysis results identify six dimensions in the interface problems, among which the experience and coordination dimensions are crucial in terms of progress rate and quality. With a view of enhancing the efficiency and effectiveness of future projects, two feasible suggestions based on the results of this study are provided for all practitioners who are engaged in dealing with these broad and complicated interface problems.
