Abstract

This paper discusses development of an assessment model and its implementation to measure the readiness of Indonesian contractors towards lean construction and to identify which parts of lean construction principles and techniques the Indonesian contractors still lack and need improvements and promotion. The model measures contractors' readiness by observing how the contractors perform their business practices at project level and rating the practices to lean construction principles. Six major building construction projects, conducted by three big wellknown contractors, were assessed as case studies. The results of the case studies conclude convergent findings since those contractors have almost similar business processes at their project levels. The case studies also revealed that big Indonesian contractors have already implemented macro lean construction principles, i.e., the policy to have continuous improvement and to promote transparency. Meanwhile, on micro principles of lean construction, i.e., reduction of cycle time and reduction of variability, the Indonesian big contractors still lack of awareness and ability to implement the principles and techniques. It is also found that Indonesian big contractors still lack the capability to plan good work flow for reducing the cycle time of their construction operations.
