Part 1- BIM in Housing Authority
B. Our Achievement on Safety
Hong Kong Housing Authority 5
BIM Project Steering Committee (BIM PSC)To plan strategically the implementation of BIM. The BIM PSC plays an important role at the management level giving direction and support to staff
BIM Working Group (BIM WG)To work on specific implementation and technical details. The BIM WG underpins the BIM PSC and is represented by all professional disciplines
BIM Service Team (BIMST)To act as central support to project teams on BIM implementation. The BIMST not only builds up in-house BIM experts, but also accelerates skill development within the department.

1) There is imminency to do BIM ourselves. The time is right, things are ready. “Learn how to swim before the tide come.”
3) Cultivate the culture of using BIM for Safety in the Department; and
2) Encourage all stakeholders (i.e. Clients, Main Contractors, Consultants) to apply BIM in the field of Safety and Construction Planning.
4) Trainings.
