Exploring interface problems in Taiwan's construction projects using structural equation modeling

Abstract

Construction projects are complex systems that inherently contain complex interface problems. This study explored the root causes of interface problems in construction projects using structural equation modeling. This technique is a systematic approach that combines factor analysis and path analysis to investigate the causal relationships among multidimensional factors. The literature on construction interface problems was reviewed, and a questionnaire survey was conducted in Taiwan to identify 27 initial factors that cause interface problems in three dimensions: owner, design, and construction. Then, a series of structural equation models (SEMs) was developed to further explore the root causes of the interface problems and their causal relationships. This study has three main findings: (1) poor design causes interface problems; (2) ineffective communication and coordination among the owner, design, and construction dimensions are the main factors that cause construction interface problems; and (3) a lack of communication and coordination has a greater influence on the construction dimension than on the owner and design dimensions. The above findings can be used as important references and sustainable management strategies for academia and decision-makers in the construction industry.
