Sponsored by William Randolph Hearst at the turn of the 20th century, UC Berkeley's Greek Theater was designed to replicate a classic Greek ampitheater. Today it hosts the University's graduation ceremonies, the Stanford vs. Cal Big Game Rally, as well as legendary performers. It seats 8,500 people and has seen performances from hundreds of musical artists and visionaries, including the Grateful Dead, the Dalai Lama and President Theodore Roosevelt.
The 109 year old, open air amphitheater is near the Hayward Fault and was in need of seismic and accessiblity upgrades. The challenge was to design and complete the renovation while preserving the historic fabric of the building all within a condensed project schedule. All retrofit work was done below ground or within the voids of the colonnade structure. Sixteen jacks were inserted under the columns as part of the underpinning scope.
Overaa's scope of work included renovation of rest rooms, copper roofing, reinforced concrete construction, fiberwrap reinforcing, lighting, new elevator, and plaster restoration. At times, crews worked into the night to complete project milestones on schedule, and finished in time for the Beach Boys to kick off the summer 2012 concert season!
