This is the second phase of an investigation into the significant factors influencing construction duration of projects in Hong Kong. The results of the first phase led to the conclusion that larger samples were justified to investigate further the discerned relationships. Expanded samples were obtained in this second phase by adding some reported data from Hong Kong projects to the original surveyed sample. The second phase of this study also further investigates the relationships between different project characteristic variables such as the construction duration, construction cost, total gross floor area and the number of storeys in the case of buildings. Moreover, a case study on plant utilization level and site labour productivity was carried out on a building site to explore the ’micro-factors’ that affect construction durations. The findings are of importance to all construction industry participants as the derived models help to estimate the construction duration of a project on the basis of significant macro project parameters. Additionally, the results of the case study indicate the contribution of significantly variable site productivity levels to overall construction duration and suggest an agenda for future investigations. A third phase of this study is planned incorporating more detailed data collection and analysis of significant factors, as well as international comparisons where possible.
