In Singapore, the Workplace Safety and Health (WSH) Council seeks to bring together designers, contractors, and clients to enhance workplace safety and health.  Since August 2016, the WSH (Design for Safety) Regulations require designers to consider safety of workers be incorporated as a part of their designs (MOM, 2016).  However, past research had shown that designers generally are not inclined to address construction worker safety in their design decisions (Gambatese, Hinze and Haas, 1997), even though in a construction project, workplace safety performance are influenced by the designers’ decisions (Hinze and Wiegand, 1992).
