Performance of the construction projects have been criticized for many years due to their low productivity rates and cost overruns as well as significant delays. Increasing number of dissatisfied customers compel practitioners to reform conventional practices of construction management. Lean construction emerges as a result of change efforts in the industry. Lean construction promises a much better project performance by eliminating the waste and improving value to customer. Although many practical application techniques of lean construction are developed, researches showing tangible benefits of them are scarce. For this purpose, this study aims to quantitatively evaluate the effects of lean construction principles on project duration and its variation. In this respect, starting from lean production subject, lean construction concept is reviewed in detail and a research methodology is developed. The methodology is based on comparing the lean and non-lean scenarios of a case study by means of Monte Carlo simulation model. Data used in the model is generated with a questionnaire responded by three experts. Research findings demonstrate that lean construction principles improve the performance both by reducing total duration of the project and its variation. The findings of this thesis cannot be generalized and this improvement may not be true for all types of construction projects. However, case study findings reveal that applying lean principles may have a potential to overcome delays and decrease unpredictability of construction project durations.
