902694- DRAWBRIDGES PAINT CONDITION ASSESSMENT

ACPWA is responsible for the management and operations of infrastructure, including streets, bridges, and flood control facilities, such as pump stations and stormwater conveyance infrastructure. ACPWA manages the planning, design, construction, and maintenance of these facilities. ACPWA's mission is to enhance the quality of life for the people of Alameda County by providing a safe, well-maintained, and lasting public works infrastructure through accessible, responsive, and effective services. ACPWA operates and maintains six drawbridges over the Oakland-Alameda Estuary. (link: https://www.acpwa.org/programs-services/infrastructure-maintenance-operations/estuary-bridges-maintenance-operation/ ) These bridges serve as a critical transportation corridor linking the City of Alameda to the City of Oakland and beyond. The three (3) bridges are assumed to be similar in scale and access difficulty; however, there may be unusual conditions, such as severely corroded members requiring structural replacement, etc. This RFP is for a paint condition assessment of the structural steel for the Park Street Bridge, Fruitvale Avenue Bridge, and High Street Bridge, and for the development of a detailed coating rehabilitation. Bridge painting work is not included in the scope of this RFP. Structural repair work, other than minor spot steel repairs necessary for assessment purposes, is not included. If significant structural deficiencies are identified, they will be addressed under a separate contract. The Park Street Bridge This is a double-leaf bascule drawbridge spanning 372 feet of the Oakland Estuary in the San Francisco Bay Area. It links the cities of Oakland and Alameda. Coordinates: 37°46′18.08″N 122°14′11.65″W Total length: 372 feet Opened in 1893, rebuilt in 1935 Repainted in 1998 The High Street Bridge The High Street Bridge is a two-lane 296-foot double-leaf bascule (drawbridge) connecting Alameda and Oakland, built in 1939 and carrying approximately 26,000 to 30,000 vehicles per day on weekdays. Coordinates: Approximately 37.7645∘𝑁-122.2250∘ W over the Oakland Estuary Length: 296 feet The current bridge is the result of the ACPWA project that replaced an earlier 1894 structure. Completely repainted in 1996 The Miller Sweeny Bridge The Miller-Sweeney Bridge is a four-lane single-leaf bascule bridge located on Fruitvale Avenue, built in 1973, and is operated by ACPWA. Approximately 15-150 vehicles cross the bridge daily. It connects Oakland and Alameda over the Oakland Estuary, providing a crucial link between the two cities, and is often referred to by locals as the "Fruitvale Bridge." Coordinates: approximately 37.77 ∘ N, −122.23 ∘ W While it has undergone several renovations, including in the late 1990s, the exact year when the bridge was repainted is not known. The County requires services for the Park Street Bridge, Fruitvale Avenue Bridge, and High Street Bridge that consist of, but are not limited to, the following: 1. A paint condition assessment of each bridge's structural steel (superstructure, substructure, movable span components, machinery housing, railings, etc.). 2. Based on the assessment, development of a detailed coating rehabilitation scope (which may include full removal/abrasive blast cleaning and repainting, or partial spot-repair and overcoating) 3. Preparation of the bid specification and cost estimate for the coating work (including paint system, surface preparation, containment, environmental/lead/Polychlorinated Biphenyls (PCB) requirements, traffic/marine/coastal considerations).
