Request for Proposal (RFP) to Provide Construction Management and Inspection Services WD-52-22

The Long Beach Utilities Department is requesting proposals for construction management and inspection services for the Large Potable Water Valve Replacement – Willow Street Project (EO-3598, WD-52-22), with proposals due July 6, 2023 at 4:00 p.m. through the Long Beach Buys portal and a digital pre-proposal meeting scheduled for June 15, 2023 at 1:00 p.m.

The scope covers construction management, inspection, and engineering support for removal and replacement of six existing 20-inch gate valves at three locations (Willow Street and Delta Avenue, Willow Street and Santa Fe Avenue, and Spring Street and Delta Avenue) with new 20-inch butterfly valves and appurtenances. Deliverables include potholing operations, line-stop assemblies, valve installation, leakage testing, disinfection, pavement restoration, and coordination with Long Beach Utilities staff and agencies. A critical subtask is Concrete, Geotechnical, and Soil Testing (Subtask No. 5), which requires the consultant to provide quality assurance testing independent of contractor quality control, including sourcing environmental subconsultants and testing laboratories for contaminated soils where applicable. All work must comply with California prevailing wage requirements and applicable federal, state, and local regulations.

The project construction cost is estimated at $1.64 million to $1.69 million. Compensation is hourly rates plus reimbursable expenses with an upper limit; the consultant must provide a detailed work plan with labor hour breakdowns by task and employee classification. Construction is anticipated to commence in November 2023 with 160 calendar days of contract time, plus 30 calendar days for post-construction administrative services. The consultant must furnish comprehensive insurance: commercial general liability ($1 million per occurrence / $2 million aggregate), professional liability ($1 million per claim), and commercial auto liability ($500,000 combined single limit). Either party may terminate with 15 calendar days' notice. The project engineer is Ardurra (Temecula, California); direct pre-award communications to Amy Czajkowski at the engineer's office or Ryan Hiney at the Long Beach Utilities Department.
