Colorado River Aqueduct Canal Liner Rehabilitation, Mile Marker 24.77 To 60.45

The project involves the rehabilitation and replacement of segments of the Colorado River Aqueduct Canal liner between Mile Marker 24.77 and 60.45, located within San Bernardino and Riverside Counties in California, an area with protected habitat requiring strict environmental compliance. Key tasks include over-excavating and re-compacting the subgrade, abating and disposing of PCB-containing coal tar coating from canal sidewalls, and restoring the site, with all work to be performed within a confined space—the open canal—while preventing contamination of the aqueduct. The scope encompasses all appurtenant work as detailed in the drawings and specifications, with materials required to be new, fully compliant, and delivered in manufacturer-sealed containers with proper labeling, including batch numbers, color designations, and hazard information. Hazardous waste must be handled and labeled per strict guidelines, and flammable materials stored in designated areas at temperatures between 50°F and 100°F to prevent degradation. The contractor must adhere to Cal/OSHA regulations, implement a site-specific safety plan, utilize proper PPE including HEPA-filter respirators and fluorescent garments, and comply with Proposition 65 and hazard communication requirements. All work must conform to Metropolitan’s Standard Detail Book and industry standards such as ASTM, with inspections conducted at both origin and destination, and final acceptance occurring at the site after correction of all deficiencies. The contract employs a Lowest Price Technically Acceptable (LPTA) award process, where only responsible bidders—who pass binary screening for criminal history, fraud, labor law compliance, and suspension status—are considered, with award going strictly to the lowest qualified bid. The only fully priced item is $600,000 for mobilization; other line items are listed with approximate quantities but no unit prices, and adjustments are permitted if final quantities exceed 75–125% of bid amounts. The work must be completed during a mandated shutdown period from January 28 to February 28, 2027, and all submissions must be made electronically via the PlanetBids portal in PDF format by August 25, 2026, with hard copies submitted to the Metropolitan Water District of Southern California’s Los Angeles office if required. Contractors must demonstrate compliance with drug and alcohol testing policies, provide a core workforce form, and meet all representation and certification thresholds, including possible SBE or DVBE status, though no certifications are pre-submitted. No named COR, COTR, or PCO are
