Biography

Ken is a licensed professional engineer with over 35 years of experience investigating damaged buildings and structures. Projects have included investigation and analysis of partial or total collapses due to fire, storms, flooding, ground movement and vehicle impacts. Ken has also evaluated serviceability issues resulting from or including water infiltration at exterior wall systems, roof leakage and construction defects. Ken’s projects often require remedial repair recommendations and analysis of code upgrade requirements. His experience includes investigation and analysis of numerous apartment and condominium complexes, industrial warehouses, commercial buildings, athletic stadiums and parking structures. Ken has developed load testing procedures to evaluate existing building elements, including the attachment of in-situ wood fiber roof panels at the Kingdome in Seattle, Washington. Ken is an experienced expert witness who has provided litigation support and expert witness testimony on many cases that have progressed to arbitration, appraisal and trial. As a Past Chair of the American Society of Civil Engineer's Technical Council on Forensic Engineering, Ken has authored and presented numerous publications. Ken also coordinated the first course in civil engineering failures (CE 594) at the University of Colorado in 1987 as he pursued his doctorate while working full time.
