Oakland Zoo California Trail

Project Details

This project doubled the size of the zoo complex to roughly 100 acres with 26 new structures, and features a new European-style, aerial gondola system. Scope covered new infrastructure and buildings including: The Landing Café,  Visitor’s and Interpretive Center Buildings, Interpretive Outlook, Lower Gondola Loading Building, Pump Station, boardwalk, a new service road, and site utilities. To help reach a target budget and make the project a reality, Overaa worked with our partners to redesign the HVAC system, provide post-tensioned beams in lieu of conventional concrete deck at the Landing Café, and propose a Mechanically Stabilized Earth (MSE) retaining wall system. Overaa also provided erosion and sediment control measures, and a temporary sound wall was installed to reduce impact of construction activity on the nearby community and wildlife. We completed the project ahead of schedule and under budget with the help of local labor, meeting both the City’s Small Business Concerns and Large Business Concerns requirements.
