Supporting the constructability review with 3D/4D models

This paper describes how the project team of the Fulton Street Transit Center (FSTC) project in New York City supported knowledge communication and generation with three-dimensional (3D)/four-dimensional (4D) models during the constructability review process. The paper analyses how 3D/4D models support the communication and generation of design, construction sequencing, and scheduling knowledge. It is furthermore analysed how the project management team used 3D/4D models to communicate the generated knowledge to non-engineers. Based on this analysis, an integrated process is suggested that can serve as a starting point to improve the application and research of how project teams can use 3D/4D models efficiently to support the knowledge communication and generation needed during the constructability review on construction projects.
