Renovate Existing Buildings & Construct New Building,
Yerba Buena Island, San Francisco, CA
This design-build project had a varied scope, which included work in seven existing buildings, installation of two hazardous material storage units, and construction of a new Boat Maintenance Building on the US Coast Guard base at Yerba Buena Island in San Francisco, CA. This project was performance-based and involved design encompassing the following disciplines: architect, mechanical engineer, electrical engineer, fire protection engineer, and structural engineer.
The project consisted of effort following areas:
Site work: underground utilities, which included the installation and termination of a new 600-pair COMM cable, existing storm, drain extension, installation of a new underground electrical distribution system, and earthwork. Work included demolition of an existing 1920’s era cast-in-place concrete structure. In place of the demolished structure, we installed two pre-engineered hazardous-material storage containers, which included fire suppression, eyewash stations, explosion proof electrical connections, and fire alarm systems.
Complete interior demolition and renovation of the existing gymnasium and locker rooms were completed in Buildings 1 and 21. The new locker rooms were brought up to current code standards, showers and restrooms were added, locker room furnishings were installed, an epoxy coated floor was installed in the locker rooms, rubber flooring was installed in the gymnasium.
Buildings 24 and 26 were originally dormitories. This project required conversion of the dormitories into modern office facilities. Work in these areas included complete renovations of the buildings to include, newly configured restrooms, new kitchen areas, revising the floor plans by removing the walls between the individual rooms, we installed state of the art communications and data systems, installed new HVAC systems which included boilers, chillers, circulating pumps, piping, fan coil units, and controls.
Work in the Command Center, Bldg 27 involved installation of an STC 50 rated wall, removal of an existing spiral staircase and installation of a traditional one, new paint, carpet, and storefront entries.
Finally, a new 4500 square foot Boat Maintenance Building was constructed. The new two-story masonry building had maintenance bays, tool rooms, supply areas, a weapons storage vault, restrooms, an elevator, office space, a kitchen, and electrical/mechanical rooms. The HVAC system for this building was also hydronic and involved a boiler, chiller, pumps, piping, fan coils, and controls. A completely new 480-volt electrical service was installed along with state of the art communications and data systems.
