With the introduction of the lean construction concept, researchers have begun to apply lean principles to construction processes. The research described in this paper applies lean principles to a construction operation using computer simulation. Simulation makes it possible to evaluate the effects of implementing lean principles into construction processes prior to real world application. A case study of the bricklaying process was conducted to quantify and evaluate the results of applying lean principles. Data required for constructing the simulation model were gathered from the construction site through work and time study techniques. Preliminary results show improvement opportunities exist in the bricklaying process due to a high share of non value-adding work. The results of lean principles implementation also reveal that lean principles can enhance the performance of the bricklaying process through more than 40% productivity improvement.

Researchers implement different methods to reduce the amount of waste in the construction industry. One of the effective methods for reducing waste is the application of lean approaches. Lean construction is a result of the introduction of a new form of production management. Although lean construction is still evolving, its generic principles, techniques and tools can already be applied. Waste reduction is one of the basic concepts of lean thinking. In general, project managers tend to conceptualize 'waste' as physical construction waste, but lean thinking believes that there are noticeable wastes hidden in construction processes (such as non–value–adding activities and waiting time). We aim at examining the ability of lean construction principles to reduce construction process waste through a case study (reinforcement process). Computer simulation is utilized to reveal the results of lean principles application prior to real implementation. Results show that different kinds of waste in a construction process can be reduced via adopting lean construction principles using computer simulation.
