Fall Webinar: Retrofit and Repair - Part Two
Wednesday, October 21st
Webinar 12:00 - 2:00 PM; Breakout room to follow after the program.
Virtual (ZOOM)

Living on the West Coast, we are fully aware of the earthquake hazard in our backyards. Please join us and our distinguished speakers to learn about ATC-143, Earthquake Damage Assessment and Repair Guidelines for Residential Wood-Frame Buildings, and case studies of both repair and retrofit.


Part 2: October 21st

Retrofit of Bakar BioEnginuity Hub at Old Berkeley Art Museum

Speaker: Masume Dana – Forell/Elsesser Engineers

The building formerly known as the Berkeley Art Museum (BAM), designed by Mario Ciampi and opened in 1971, is an architecturally significant reinforced concrete building listed on the National Register of Historic Places and designated as a Historic Landmark by the City of Berkeley. As a successful adaptive reuse, the transformation of this landmark museum building into biosciences incubator and research labs is desirable from both a historical and sustainability perspective. The challenges of the project include incorporating an effective seismic retrofit into a very complicated non-orthogonal three-dimensional space, preserving the historic exposed concrete structure as much as possible, replacement of almost all M/E/P/S systems, roofing and skylights, and upgrades to accessibility. ASCE 41 standard Nonlinear Dynamic Procedure was used for the seismic evaluation of the existing structure and the retrofit design including the effects of the deep foundations.

Repair and Retrofit of the Historic Trefethen Winery Building

Speakers: Marianne Wilson & Brett Shields - ZFA 

The Historic Trefethen Winery Building was constructed originally in 1886 and is the only surviving 3-story heavy timber wood framed winery building still being used as originally intended within the State of California. The wooden structure was famously and dramatically damaged to within a whisper of collapse during the August 2014 South Napa Earthquake. This presentation chronicles the history of the building and the specific and special steps toward both structural repair and retrofit which occurred over the course of the following 18 months.

Speaker Biographies:  
Masume Dana is a licensed structural engineer and a Senior Associate with Forell/Elsesser Engineers. Masume has over 14 years of experience and brings experience with all major construction materials for museums, educational, office and commercial, laboratory, and industrial structures. Her broad skill base in the area of seismic analysis of structures includes nonlinear dynamic analysis techniques applied to many complex projects from new construction with viscous dampers to existing buildings seismic retrofit such as Bakar BioEnginuity Hub at Old Berkeley Art Museum.
Marianne Wilson is an Associate Principal at ZFA, where she began her career in 2006 with a degree in Architectural Engineering from Cal Poly, San Luis Obispo.  Her experience lies primarily in the review and retrofit of existing structures utilizing ASCE 31 and ASCE 41 and in custom residential new construction.  She has evaluated and repaired many existing structures for continued occupancy and reuse for both Life Safety and Immediate Occupancy categories. Marianne has also been heavily involved in the preparations of ZFA’s standards for use of the new ASCE 41 code in evaluations of buildings. These standards have been applied across multiple jurisdictions to identify and communicate structural deficiencies to clients and provide recommendations for retrofit.
Brett Shields is a Senior Engineer at ZFA with a Bachelor’s and Master’s Degree in Architectural Engineering from Cal Poly, San Luis Obispo. In his position at ZFA, where he began his career in 2013, Brett has become a highly valued company resource and is often called upon for his structural analysis, attention to detail, and BIM modeling capabilities. His wide-ranging experience includes historic repair and retrofit, essential service facility, public, commercial, and educational work. He is often called upon to assist with complex and challenging projects. Brett’s ability to conceptualize, create, develop, and communicate innovative designs and details make him a valuable addition to any project
