Hong Kong possesses one of the world’s largest public housing stocks which provide accommodation for 3.1 million people. To meet the growing need for public housing, the government has committed to produce 50,000 public flat units (plus 35,000 units from private developers)

With the complexity in public housing construction (Chan et al. 1995), simulation provides a sound technique for investigating the process in more detailed. This paper presents a study on modeling and simulating the public housing construction by considering the major resources and operations. The construction time of a typical floor cycle and utilization of resources will be highlighted.

Hong Kong possesses one of the world’s largest public housing stocks that provide accommodation for half of its population, or 3.1 million people. These public housing stocks are allocated to its residents through renting or home ownership schemes. Two government bodies, the Housing Authority and Housing Society, are responsible for developing, allocating, and maintaining the public housing properties. According to the government prediction, Hong

Computer simulation can model a construction process on the operational level by considering the random nature, resource-driven characteristics and dynamic interactions during operation (Shi and AbouRizk 1997). It has been proven to be a very effective tool for planning and
