Designing construction operations for productivity improvement is an important tool for making the right engineering decision regarding the optimal employment of machinery and human resources needed to accomplish these operations. This paper presents a simulation model designed based on CYCLONE elements to simulate lifting and transporting of the brick in many commercial and residential buildings. The model uses actual data collected from field. These data are used to test the model designing accuracy for further productivity improvements. Three probability density functions (triangular, normal, and deterministic) were used to model the random duration of several tasks involved in the proposed operation. Results showed that triangular distribution is well fitted and the model productivity is only 3% higher than the actual productivity. This means that it is possible to use this model in improving the productivity of later operations. The model was tested to determine optimal performance of the human resources used in the model.
