The recommended modernization improvements is to make the entire building accessible and renovate the interior of the building by making efficient use of existing spaces. In addition, a new covered entry is being proposed to bring the facility entry out to the sidewalk and create a more inviting atmosphere.
The main second floor and roof is a reinforced concrete slab supported on concrete girders/beams. The general condition of the building is good, it has been well maintained since its construction.
Bayview Branch has been designated with a seismic hazard rating of 2. Therefore, seismic retrofit solutions will be limited to localized strengthening of individual members. The building’s relatively new construction put this branch among the safest in the City.
The existing main entry ramp does not meet current code. A new entry ramp and a new elevator will be added to make the first and second floor fully accessible. New or enlarged restrooms will be accessible. Signage will be introduced for improved accessibility.
The mechanical and electrical systems will be cleaned and inspected for potential code upgrades. Fire egress and fire protection systems will be improved to meet current code requirements and life safety.
It is recommended that a new electrical panel be installed to serve sensitive loads such as computers. Any proposed new electronic loads will be served from the new sensitive load panel. The new panel will be served from a feeder breaker in the main panel. The building materials will be tested for the presence of asbestos or lead containing materials for possible mitigation measures.
The entire first floor will be renovated to include a new elevator, new restrooms, and more efficient storage and janitor closets. On the second floor, the existing restroom will be enlarged and existing lighting systems will be enhanced. Existing counters and office areas will be reconfigured to make more efficient use of staff areas.
Air circulation in areas with no windows will be improved. The meeting room will be updated with data/electrical outlets and media presentation equipment.
