Studies have shown that the current process involves a wide range of non-value adding activities, resulting in poor process efficiency. This paper presents a model developed for discrete-event simulation of activities and resource use involved in the construction of in situ cast concrete frameworks in multi-storey housing. The model simulates the work flow which is subject to multiple work locations and resource availability constraints. The model has been developed and validated by studying four ongoing projects. The model functionality and simulation approach are described. The validation of the model is also described and finally a parametric study is conducted to demonstrate the use of the model. It is shown that the model can reproduce the dynamic behaviour in a work flow constrained by resource availability. The model can be used to analyze how different production strategies involving resource allocation influence total construction time and cost.
