Welcome to the website of the International Group for Lean Construction!

The International Group for Lean Construction (IGLC), founded in 1993, makes up a network of professionals and researchers in architecture, engineering, and construction (AEC) who feel that the practice, education, and research of AEC have to be radically renewed in order to respond to the challenges ahead.

We call our vision: Lean Construction

Our goal is to better meet customer demands and dramatically improve the AEC process as well as product. To achieve this, we are developing new principles and methods for product development and production management specifically tailored to the AEC industry, but akin to those defining lean production that proved to be so successful in manufacturing.

The distinguishing trait of this Group is its emphasis on theory. We view that the lack of an explicit theory of construction has been a major bottleneck for the progress in the AEC field. Conversely, we assume that the clarification of the theoretical foundation of construction, along with principles and methods emanating from the new foundation, would be the most effective means for the renewal of the AEC industry.

Annual conferences are the main activity of the Group (you can find papers presented or at least abstracts as well as information on the upcoming conference). Ten Subgroups addressing specific themes, are discussed: Theory, Production Planning and Control, Product Development and Design ManagementProduction System Design, People, Culture and Change, Supply Chain Management, Prefabrication, Assembly and Open BuildingEnabling Lean with ITSafety, Quality and the Environment,Contract and Cost Management. There is also a European Chapter (EGLC) organising workshops and group discussions. The group has an e-mail list, to which everybody interested may subscribe. A bibliography on Lean Construction is provided. A number of related Web services are also presented. For those planning to start thesis research on lean construction we have compiled lists on prior theses and worthwhile research topics.
