Exploring the Opportunities for
Applying Lean Principles to Electrical Prefabrication
H. W. Chris Lee, Ph.D.Oregon State University
July 22, 2013
Working Hypotheses
1. Electrical construction has its own unique barriers to prefabrication
2. A project that applies more lean principles provides more opportunities for electrical prefabrication

Project Objectives
Identify barriers
Investigate a list of lean principles
Develop a leanness scoring matrix
Increased Prefabrication in Electrical Construction
• Organizational• Contractual• Technological

Project Tasks
1• Interviews to identify barriers
2• Case studies to identify lean principles
3• Cross-case analysis to develop the leanness scoring matrix
4• Documentation
(Tentative) List of Lean Principles
• Design alignment– Design for Prefabrication– BIM implementation
• Variability management– Lead time/Labor/Quality/Design
• Inter-organizational collaboration– Multi-trade cost and design management
• Alignment of commercial interests– Integrated contracting methods

(Tentative) List of Barriers
• Organizational– Late decision making– Lack of pre-planning– Inflexibility of construction workflow– Lack of (field personnel) buy-in
• Contractual– Lack of contractors’ involvement– Lack of multi-trade communication
• Technological– Interoperability issues of design software
