This study aims to investigate the influence of coordination problems in glass and metal curtain wall (GMCW) installation on project productivity in Singapore. Trade-level coordination problems in GMCW installation were identified through literature review and included in a survey questionnaire. The survey results indicated that, on average, 66.5 days of rework and 52.5 days of waiting resulted from coordination problems, and that “last-minute changes in design by the client” led to the longest rework and waiting time. Additionally, the rework and waiting time caused by trade-level coordination problems were correlated with the total rework and waiting time.
