R-7235 Marine Maintenance Yard Dock Replacement

The City of Long Beach Department of Public Works is procuring construction services for replacement of the Marine Maintenance Yard Dock at 6204 E. 2nd Street under R-7235, with bids opened July 29, 2024, at 2:00 p.m. The project is subject to prevailing wage requirements under California Labor Code § 1720 and a Citywide Project Labor Agreement with the Los Angeles/Orange Counties Building and Construction Trades Council, imposing a 40% local hiring goal and a 10% transitional/veteran worker hiring goal.

The scope encompasses removal of two existing 14.5' × 59' concrete docks, a steel gangway, gangway hinge, concrete staircase, and potable waterline, with installation of a new singular 14.5' × 59' concrete dock (855.5 square feet), 4' × 45' aluminum gangway, concrete abutment, 3/4-inch copper potable waterline with utility rack, aluminum guardrail (approximately 7.5 linear feet), and 18-inch steel guide pile HDPE sleeve repair. Concrete dock design requires 5,000 PSI minimum concrete (Type II/V) with post-tensioning, epoxy-coated reinforcement steel, and sustains a 100 PSF uniform live load with maximum 18-inch draft under dead load only. The aluminum gangway must support 100 PSF distributed live load with deflection not exceeding L/120 of span and comply with ADA guidelines. Steel pile repair requires SeaShield 525 Epoxy Coating or approved equal applied to the top 20 feet using high-pressure water blasting at minimum 3,500 psi, with diving work performed by certified divers and turbidity curtain required.

Bidders must hold a valid California Class A General Engineering Contractor license and demonstrate qualifications through evidence of at least two successfully completed reinforced concrete dock projects within the last five years with a combined minimum 1,000 square feet of installed concrete docks. The contractor must achieve a minimum 50% self-performance threshold. All contractors and subcontractors must register with California's Department of Industrial Relations prior to bid opening. A 10% bid bond and performance and payment bonds upon contract award are required.

The engineer's estimate is $1.0 million with a project schedule of approximately 130 work days from Notice to Proceed. Two responsive bids were received: Jilk Heavy Construction, Inc., at $728,960.00 (88.12% self-performance) and The Dutra Group at $1,133,000.00 (95.15% self-performance). Three addenda were issued between June 27 and July 19, 2024, addressing design clarifications, pile repair specifications, aluminum finishes, and concrete dock loading parameters. Anticipated award was late August 2024.
