• The Hong Kong Housing Authority (HA) is a statutory body established in April 1973 under the Hong Kong Housing Ordinance. The Housing Department is HA’s executive arm.

• HA develops and implements a public housing programme to meet the housing needs of people who cannot afford private housing.

• Approximately 30% of the Hong Kong population is now living in public rental housing units.

• The HA has an existing stock of about 730,000 rental flats.

• We build 79,000 new PRH flats for five years from 2012/13 to 2016/17 and build 100,000 new PRH flats for the five years starting from 2018.

• We build 17,000 new HOS flats for four years from 2016/17 to 2019/20 and thereafter 5,000 new HOS flats a year.

BIM is not just a tool,BIM is not just a tool,it brings transformationit brings transformation

to construction industry…to construction industry…

Transformation Process

BIM 3D modelling, Analysis, 3D printer, RFID, GIS, R&DTechnologies

Upfront design process, re-engineering, office procedures, disciplines practices, industry practices

Processes

Tighter team formation, multi-disciplinary team, supporting team structureOrganization

Collaboration among project team, consultants, contractors and subcontractors.

Partnership

Training to HA Staff (includes professionals & technical staffs)

Our Goal Apply BIM to all new projects from design stage by 2014/15

About 1,360 staffs(about 70%)*

* As at the end of December 2013

• Architects• Building Services

Engineers• Civil Engineers • Geotechnical Engineers• Land Surveyors• Landscape Architects• Planners• Quantity Surveyors• Structural Engineers• Site StaffTentatively, it will be more than 85% in 2015

(V) Way Forward &

Conclusion

51

Local Universities & Academia

• Prevalent research topics.• BIM courses.

Professional Service Providers• BIM models support submissions.

Construction Industry• Enhance collaboration among design team, contractors, sub-contractors & suppliers.• Contractors have set up their own BIM working teams.

Major Government Departments

Construction Industry Council

• BIM Task Force in the Construction Industry Council of Hong Kong• Chaired by Ms. Ada Fung with members from academia, professional institutes,

developers associations, government departments, etc.• Develop a BIM roadmap for HK Construction Industry
