Lean construction technique has been arisen from endeavouring and applying Japanese lean manufacturing philosophy to the construction industry. Large research is being done recently and an ongoing process to adopt lean principles to the construction industry to enhance the efficacy, amelioration of waste. The success of the lean technique is evident, but some major reports indicated that major challenges are related to the Mis-conceptualisation of lean thinking, and some case studies have ascertained that the lean technique was either applied partially or erroneously. The purpose of this paper is to elucidate the lean concept, wastes in construction, features of lean project delivery, lean principles and the barriers to implementing the lean technique in the Gujarat construction industry. A compendious review of the literature had been done with the perspective of reaping pertinent data needed for the paper and to make a questionnaire. To check the reliability of data Cronbach’s alpha was used. Followed by a statistical analysis of data by Relative Important Index (RII) and ranks were given. Further analysis discovered that only nine of these barriers were determined significant, where dominant factor was Resistance to change and culture with an RII value of 0.63. The results of this study could be used to help researchers, practitioners and companies in the Gujarat construction industry to fasten their attention on the suggestive issues to the prosperous implementation of the lean concept.

Building information (BIM) is becoming a better-known collaboration process in our construction industry. BIM is a systematic process that amalgamates all the other geometric computer-generated models, or data that creates simulations that can be used for the project manager, owners, facility manager or other parties to look after the project and deliver the project more efficiently. The implementation of BIM in India is still at a nascent stage due to a lack of knowledge of the advantages of BIM. Moreover, there have been only a few case studies conducted in India about BIM; therefore, the principal agenda of this study is to enlighten the readers about the benefits accrued if BIM is applied, in the residential project, before the construction. Hence, the authors had taken a residential project located in Gujarat, India, for a case study. The 3D and 4D models of the project were generated; 8 errors were identified that could have been detected before construction if BIM had been applied. The cost needed to make a BIM model was ₹ 171,050. Whereas, the amount that could have been saved if BIM was implemented beforehand was discovered as ₹ 246,773. Consequently, the benefits to cost ratio for two weeks in delay was determined as 1.44. It can be as the benefit of BIM for construction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
