|Abstract:||Over the last 25 years, the construction industry has become less efficient despite having traditional project delivery systems like IPD, DB, DBB & CMR. the amount of waste (man, money, material, time) in construction activity is not properly reducing due to the complexity of infrastructure projects. For waste reduction proper optimizes solution and interdisciplinary teams are required. Integrated project delivery (IPD) is to improve project outcomes through a collaborative approach by early involvement of all parties, while Lean construction refers to the adaptation of the concepts and principles of the Lean production system to construction for maximizing value and minimizing the waste. So, Lean Integrated Project Delivery (LIPD) is the best option as a combination of collaborative alliance and malty party agreement of IPD for achieving combined project goal and Waste reduction strategies of lean for customer satisfaction. This work is an experiment to developed waste generation model of construction waste for LIPD in infrastructure projects of Gujarat. A total of 78 success factors related to waste generation were identified in 8 different parts from the review of related literature and interview with field experts. The questionnaires were designed according to factors identified and requirement of LIPD which is filled by 41 experts of an infrastructure project. AHP analysis was used for extracting 16 most critical factors from total numbers of factors which are responsible for waste generation. Factor analysis was used for the cross verification of results of AHP analysis. Interpretive Structural Modeling (ISM) was used for development of hierarchy base model in reference to dependent and driving power of 16 Most critical factors. And from the model, we can identify that “Poor Project Planning” is the factor which drives all other factors. This would act as a design making support tool for project teams for waste reduction using LIPD. Key words: AHP, ISM, LIPD, Waste Generation, Construction Activities, Waste Reduction.|
