Scope of Services
The City of San Diego received Federal Highway Administration (FHWA) Highway Bridge Program (HBP) Funding administered through the California Department of Transportation (Caltrans) to rehabilitate the Fairmount Ave Bridge Left/Right. The bridges, located southeast of Mission Valley in the City of San Diego, are classified as "Structurally Deficient" by the California Department of Transportation (Caltrans). The existing bridges are located on Fairmount Avenue at the intersection of Aldine Drive. Fairmount Avenue is a divided four lane Urban Principal Arterial that runs south-north with a posted speed limit of 55 mph in the northbound direction and 50 mph in the southbound direction. It is a local route that primarily services the communities of Kensington and Talmadge south of I-8 and provides additional connectivity to Normal Height and City Heights. The substructure of both existing bridges consists of three continuous reinforced concrete box girder spans on two open end reinforced concrete diaphragm abutments and two reinforced concrete column bents, supported by steel piles. Each bridge carries two lanes of vehicular traffic with no shoulders and no sidewalk. The overall width of each bridge deck is 28 feet. Phase 1 of Fairmount Avenue bridge rehab east/west project that included preliminary engineering studies and evaluations, preliminary environmental and preliminary geotechnical study has been completed. Different alternatives for bridge rehabilitation and replacement were developed and final alternative 3A is selected as the following: Proposed project will involve widening the existing bridges with precast concrete box girders to provide two 12-foot lanes, an 8-foot outer shoulder, a 4-foot inner shoulder, and a barrier-separated 6-foot sidewalk. Other design elements include providing 6-foot sidewalks along the north side of Aldine Drive between the ramps to Fairmount Avenue, a retaining wall along the northbound Fairmount Avenue on-ramp, and ADA upgrades. Under this proposal, consultant will need to provide work for phase 2 that includes: Preparation of environmental document (CEQA and NEPA), final plans, specifications, and estimates (PS&E) for final alternative selected in Phase 1. Also, to include any environmental studies, technical reports or memorandums that may be deemed necessary to complete PS&E phase. Engineering support during the bid and award phase for construction contract and engineering support during construction, including the assistance in preparation of the As-builts for the project upon construction completion.
