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.
Highlights
Every construction project is a specific and unique system
The root causes of interface problems must be predicted or identified in a timely manner so that these problems can be solved effectively. Failure to identify these factors will result in unpredictable and uncontrollable events that impede the completion of construction projects; in addition, an antagonistic relationship may form among the interested parties, reducing the effectiveness of project implementation through low productivity, cost increases, and schedule delays
The purpose of this study is to develop a series of structural equation models (SEMs) to explore the root causes of project interface problems among three dimensions: owner, design, and construction
Summary
Every construction project is a specific and unique system. Because of the rapid development of modern technology, the scale of construction has gradually increased, and construction projects have become increasingly complex. The root causes of interface problems must be predicted or identified in a timely manner so that these problems can be solved effectively. Failure to identify these factors will result in unpredictable and uncontrollable events that impede the completion of construction projects; in addition, an antagonistic relationship may form among the interested parties, reducing the effectiveness of project implementation through low productivity, cost increases, and schedule delays. Contractors, design consultants, and business owners all believe that construction interface problems can influence the results of project implementation and determine the successful completion of projects while meeting predetermined requirements
