Precast workflow productivity measurement through BIM adoption

Building information modelling (BIM) is acknowledged globally as a key computer-aided technology that expedites construction productivity enhancements. Consequently, the utilisation of BIM has been gaining precedence in Singapore’s construction industry during the past few years, aiding enhanced project management. Productivity improvement has been a concern for the construction industry in Singapore in the last decade, and the method of measuring productivity improvement is one of the major issues. This study adopts a quantitative research and development approach to determine the impact of BIM on the productivity of Singapore’s precast industry. On the basis of the observations of the authors on the workflows followed by three precast firms in Singapore, this study aims to propose and apply a fuzzy mapping technique to measure productivity improvement; furthermore, it also identifies the constrictions in the present workflow and proposed an improved workflow to address the prevalent constraints to facil...
