Conformance Evaluation of Lean Integrated Project Delivery (LIPD) for Indian Construction Industry

Integrated project delivery (IPD) can be used to improve project outcomes using a collaborative approach through early involvement of parties and a multiparty agreement. Lean construction refers to the application & adaptation of the Toyota Production System (TPS) concepts and principles in construction projects for the reduction of waste. Over the last 20 years, the construction industry has become less efficient despite having good project delivery systems like Integrated Project Delivery (IPD), Design-Build (DB), Design-Bid-Build (DBB) and Construction Management Risk (CMR). The amount of waste (man, money, material & time) in different construction activities needs to be minimized to the maximum possible extent. An efficient project delivery system is missing for the Indian construction projects. This research work introduces Lean Integrated Project Delivery (LIPD) as a solution which uses a combination of lean management principles & IPD for waste reduction during construction activities. Further, LIPD conformance would be carried out in the Indian construction industry for the successful implementation of new project delivery system by identifying Critical Success Factors (CSF). Till date, there is no research carried showing LIPD conformance in India. Data for this research has been collected using questionnaire survey using Saaty’s scale from experts working in several construction industries of India and has been analyzed using Analytical Hierarchy Process (AHP). The sample size for research work is 40, which was collected from 24 different construction & project management companies in India. This paper elaborates conformance of LIPD in India and the reason for poor implementation of the same. © 2019 The Authors.
