BIM Case Study - Hong Kong Housing Authority
WSP is involved in the second phase of the 250,000 m2 development, which has a construction cost of around HK$600M and includes one residential block (out of a total of nine), a commercial centre, a car park block and a public transport interchange.
The BIM consultancy covers the entire site. WSP is using BIM to assist in the design visualisation and coordination and is also conducting a research project to develop the workflow so that the BIM model becomes the source of information for various analyses including sustainability (solar study, wind study, noise analysis, etc.) and links to the structural and civil engineering including external underground drainage and utilities and landscape. The model incorporates the drawings of other design consultants, including architects and MEP engineers, who produce these independently using traditional CAD. In this way the designs of the different disciplines are coordinated, enabling the visualisation of different options for improvement and early identification of clashes and other problems. Three BIM packages are used – Autodesk Revit Structure, Architecture and MEP.

In carrying out the civil and structural engineering designs for this part of the project, WSP uses BIM primarily for drawing production.
The software used is Autodesk Revit Structure 2011 and the benefits of its use include helping the engineers to easily understand the design, providing a centralised database to ensure the latest information is always available from the model, and for enhanced efficiency of drawing production. |
In this project WSP’s BIM consultancy also plays a special role in serving as a template for Hong Kong Housing Authority (HKHA) to use BIM to its full potential in project design and management from concept stage to completion of construction. HKHA builds 15,000 public housing units a year and is aiming for full implementation of BIM on all its housing development projects by 2014.
