Why Join LCI?

With its roots in production management, Lean practices produce significant improvements in schedule with dramatically reduced waste and enhance owner value, particularly on complex, uncertain and quick projects. Join our rapidly growing membership, comprised of forward-thinking owners, the design community (architect and engineering firms), general contractors and trade contractors — all of whom share a common goal to transform the design and construction industries.

Our members benefit from:

Cutting-Edge Training

Members enjoy reduced prices for our extensive series of LCI trainings, including our popular "Introduction to Lean Construction," a 1-day seminar covering the Lean Project Delivery System.

Future Trends & Networking

Networking and sharing stories about Lean successes and challenges is truly the hallmark of our LCI member events. In fact, it was the catalyst for the creation of LCI. From the beginning, LCI members have made a point to share information with one another, despite being competitors, for the betterment of the industry.

Ongoing Education

Continuing education is at the core of what we do. We offer education programs throughout each year at both national forums and local Communities of Practice, where we share new learnings and address questions and methods. Seminar topics include the tenets of Lean (Project Definition, Lean Design, Lean Supply, Lean Assembly, Production Control and Work Structuring) as well as specific topics such as safety, contractual agreements, cost control and implementation approaches. Our education sessions are known for facilitating some of the best conversation in the industry.

Members-Only Website Access

LCI maintains an extensive collection of materials, forms, articles and technical information in a password-protected section on this site. Check out the latest information on The Last Planner® System, the UHS Lean Delivery Guide and trending white papers and readings.

Supporting Materials

To help our members in their Lean journey, LCI maintains an extensive (and growing!) library of training materials, handbooks and planning tools to help member companies train their own employees, as well as those in their supply and demand chains. We also provide consulting through member partners for our trademarked Last Planner® System (LPS), the basis for Lean implementation.

Surveys & Innovative Research Findings

Innovations develop where concept and practice intersect. And new solutions require new thinking! Joint exploration carried out by LCI members and researchers is the key to innovation and continuous improvement. Together with our members, LCI explores new approaches, research projects, and potential products for the betterment of the industry.

LCI Journal

The Lean Construction Journal is LCI's internationally-refereed journal devoted to Lean Construction practice and research. Since 2003, the Lean Construction Journal (LCJ) has published articles on research approaches, findings and theoretical foundations, as well as practitioner reports, case studies and essays from the field. Its primary objective is to stimulate a systematic rethinking of the construction process, both on- and off-site, by providing a forum for disseminating knowledge and exchanging ideas between industry and academia.

The success of Lean Construction Institute’s (LCI) efforts to transform the design and construction industry is in large part due to our incredible member base and the collaboration of ideas from leaders across the design and construction industries.

Our member base is comprised of:


We promote owners' understanding of the benefits of Lean, including: enhancing the ability of contractors and designers to meet conditions of satisfaction at every stage of project production; keeping projects on or ahead of schedule; reducing waste; and cut cost throughout the project life cycle. Our distinguished, nationally-recognized owner organizations are represented in both our membership and on our board of directors, including such organizations as Intel, Universal Health Services, UC/San Francisco, and Google.

Design Professionals

By engaging concurrently in the design process with those who will procure services and execute the design, the client's concerns and changing needs can be better identified and satisfied as they arise. Our growing list of members from the design community are benefiting greatly from Lean's ability to enhance value in designs. Membership in LCI affords architects as well as engineering and design firms a unique opportunity to explore how Target Value Design and other Lean techniques can enhance designs, boost productive collaboration, and save clients time and money.


Lean tools and techniques provide a structured and proven approach to collaboration in all aspects of project delivery, from initial design work to final delivery to the client. Contractors are benefiting greatly from Lean approaches to eliminate waste, promote on-site safety, keep projects on or ahead of schedule, and get everyone in the supply chain working together most effectively for the benefit of the project as a whole. Delivering projects at less cost, on or ahead of schedule, with better owner satisfaction at every stage of the process, creates an incredible competitive advantage.

Trade Partners

Our trade partner members are discovering that participation in Lean projects makes their voice a more respected one at the table, providing an opportunity to head off poor scheduling decisions that drive waste, re-work and general frustration. Much like our contractors are experiencing, trade partners are able to deliver projects at less cost, on or ahead of schedule, with better owner satisfaction at every stage of the process, creating the potential for significant competitive advantage.
