Construction is a complex and challenging process consisting of various kinds of waste resulting in client dissatisfaction, cost and time overrun. Waste is defined as a non-value adding component which uses project resources and efforts without achieving any objective. Factors leading to waste in construction are termed as "causes of waste". Current construction practices are unable to eliminate these "causes of waste" due to limited use of technology. This paper presents an IT based methodology to eliminate various "causes of waste" to support lean construction and thereby making the construction process efficient. A questionnaire survey was carried out to investigate major "causes of waste" in the Indian construction industry. 30 major "causes of waste" were identified in the design process, construction planning and site management process, and mal-administration. Literature review helped us identify 13 available IT applications for lean construction. This study aims to link the identified IT applications with relevant "causes of waste" through the developed relationship matrix to mitigate waste causing activities. It was observed that 23 out of the 30 identified major "causes of waste" can be eliminated from 13 identified IT applications.
