IGLC 2020

Who We Are

Founded in 1993, the IGLC (iglc.net) is an international networked community of researchers from practice and academia in architecture, engineering, construction, and facility management (AECFM) who feel that the practice, education, and research of the AEC industry have to be radically renewed in order to respond to the global 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.

In contrast to other industry organizations, the distinguishing trait of the IGLC is its emphasis on theory. We view that the lack of an explicit theory has been a major bottleneck for the progress in the AECFM field. Conversely, we assume that the clarification of the theoretical foundation, along with principles and methods emanating from the new foundation, would be the most effective means for the renewal of the AECFM industry.

IGLC28 Conference Week July 6-12, 2020 in Cusco, Peru

To promote sharing and vigorous discussion of theoretical developments of Lean Construction and lessons learned from its application in practice, the International Group for Lean Construction (IGLC - iglc.net) hosts an annual conference. The 2020 conference is the 28th of its kind, and will be held the week of July 6-12 in Cusco, Peru. Each year’s conference is managed independently by a group of volunteers in the sponsoring country, who help deploy and further advance lean construction practices in the host country while recognizing the need for contextualized application.

Accordingly, the IGLC28 week starts with two days of industry-oriented workshops and presentations. These are followed by two and a half days for the technical conference that includes report-outs of Lean Construction advances around the world. IGLC members hold their annual business meeting on the third day of the technical conference. After the technical conference, IGLC members host a Summer School for students pursuing PhD research pertaining to Lean Construction.

Annual conferences are the main activity of the IGLC, and their locations rotate amongst the continents
