Working Hypotheses • Electrical construction has its own unique barriers to prefabrication • A project that applies more lean principles provides more opportunities for electrical prefabrication Photo courtesy of Oregon Electric Group
Project Objectives Increased Prefabrication in Electrical Construction 3 2 1 • Organizational • Contractual • Technological
(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 Photo courtesy of OEG
