Simpson Gumpertz & Heger Inc. (SGH) is a national engineering firm that designs, investigates, and rehabilitates structures, building enclosures, and materials. SGH has been working on California’s historic landmarks for over 35 years. Our preservation technology group combines structural and building enclosure engineering with in-house laboratory services to provide a comprehensive approach to assessment and restoration.
SGH works with clients to help define the proper level of intervention for each building or structure we work with. We do this through investigation and diagnosis, options planning and analysis, repair documents, and construction administration. Our knowledge of historic building systems allows us to better evaluate the structure and building enclosure and prepare an appropriate, durable, cost-effective design. Our work complies with the Secretary of the Interior’s Standards for the Treatment of Historic Properties. For more information, visit www.sgh.com.
