As a concept, lean construction is still considered as a new paradigm among Indonesian construction practitioners as well as academia. Introduction of lean construction concept to Indonesian construction industry becomes a strategic, challenging, and painful effort as a prophet looks for the believers. Although some lean construction principles and techniques are already adopted and implemented by construction practitioners in their day-to-day activities, understanding of lean construction concept, principles, and techniques becomes a big agenda for research and education in Indonesia. One of the important assumptions made on the development of the agenda is the capacity of parties involved in Indonesian construction industry, especially contractors which are the most important actors at the production line of construction projects. An assessment model was developed to measure the readiness of contractors toward lean construction for this purpose, Furthermore, the model is also developed to have a clear picture on which parts of lean construction principles and techniques the Indonesian contractors still lack of and need improvement and promotion. The model measures contractors' readiness by observing how the contractors perform their business practices on the project level and rating the practices to lean construction principles, i.e. whether the contractors' practices could reduce cycle time, reduce variability, increase transparency, and be continuously improved. Six projects constructed by three big contractors were observed as case studies by interviewing relevant and capable respondents in the fields. Based on the assessment model, it was found that those contractors have almost similar business processes at project level, and therefore the results of the case studies could conclude convergent findings. The case study revealed that Indonesian contractors 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 variability, the Indonesian contractors still lack of awareness and ability to implement the principles and techniques.
