The modular construction market is projected to grow from $75.89 billion in 2021 to $114.78 billion in 2028 at a compound annual growth rate of 6.1% during 2021-2028 mainly due to the benefits of reduced waste, building speed, flexibility, and cost-effectiveness. Lean methodologies are playing a part in helping that growth.
We’ll take a look at a comprehensive overview of Lean implementation in the modular building industry, a US government report on Lean applied to factory home building, a case study from Lebanon, and finish with a short video on why modular construction lends itself to Lean.
Implementing Lean Methodologies in the Modular Building Industry: An Overview
In a paper titled “Lean Methodologies and Techniques for Modular Construction: Chronological and Critical Review,” authors Filomena Innella, Mehrdad Arashpour, and Yu Bai discuss the implementation of Lean methodology in all the production process stages in the modular building industry.
The paper includes
- Table of Lean Construction Methodologies, Techniques, and Tools with Associated Reference Sources
- List of Selected Sources for Systematic Review
- Lean Construction Tools Mentioned in Case Studies

A Housing and Urban Development government report titled “Pilot Study: Applying Lean Principles to Factory Home Building” includes multiple case studies of Lean implementation.
The report includes several examples of Lean implementation:
- R-Anell Housing
- Southern Energy Homes
- Chelsea Modular Homes
- Hi-Tech Housing
- Palm Harbor Homes

Using Value Stream Mapping in Modular Construction: Lebanon
In a case study titled “Integrating Lean Into Modular Construction: A Detailed Case Study of Company X,” authors Fatima Alsakka and others discuss the use of value stream mapping in precast concrete pre-slabs in modular construction.
The case study includes:
- Current State Map
- Future State Map
- Necessary Improvements for a More Lean Process
- Long Term Future Recommendations
