| Abstract: | 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. |
