French and Evergreen Theatres Seismic Upgrade and Renovation

AHBL provided civil and structural engineering for the renovation of the French and Evergreen Theaters. Originally constructed in the 1920s, the 6,359-SF French Theater was remodeled around 1940 to increase its size to 10,439 SF. The Evergreen Theater was constructed around 1960 and totals 14,681 SF.

Initially, the client believed both buildings required roof repairs and refinished stage floors. However, after a field investigation, it was determined that only the Evergreen Theater required a refinished stage floor, and only the French Theater required roof repairs. AHBL also performed life-safety evaluations to assess each building’s vulnerability to seismic events. The evaluations found the Evergreen Theater to be in good condition. However, the lateral force-resisting system in the French Theater provided little, if any, lateral resistance, requiring AHBL to develop a seismic upgrade design.

In addition to the seismic upgrades, AHBL collaborated with the architect to restore the historic character of the French Theater’s façade to its 1940s condition, including the restoration of three wide glazed openings at the front of the building. Windows, doors, and associated framing were upgraded to meet mandatory Department of Defense security requirements for all building renovations and major modifications and were replaced with units that maintained the general appearance of the originals.
