Wetwell Level Monitoring Upgrade At Collections Pump Stations

The contract involves upgrading wetwell level monitoring systems at five pump stations operated by the Orange County Sanitation District, with specific scope differences across locations. At Crystal Cove, MacArthur, Main Street, and Slater stations, the work includes installing new level transmitters and modifying existing control systems to enable local selection between measurement devices. At Edinger Pump Station, the existing bubbler system is to be replaced with a new bubbler panel featuring redundant instruments and an automatic blowdown function. All work encompasses associated raceway, conductors, and control panel modifications, requiring full installation, testing, commissioning, and integration with existing electrical and structural systems. Work must comply with NEC, UL, IEEE, OSHA, and California code standards, with inspection and acceptance occurring on-site by the Engineer and final approval granted by OC SAN. Testing must follow NETA standards, with pass/fail criteria including insulation resistance above 50 megohms and functional verification of alarms and controls. The contract is valued at $450,000 with a lump sum payment structure for mobilization and unspecified pricing for the remainder of the work. Payments are processed net 30 days upon submission of itemized applications via OC SAN’s Project Control and Management System, with retained funds and audit rights maintained per internal General Conditions. Contractors must hold a California Class A or C-10 license, perform at least 30% of the work in-house, and adhere to strict safety protocols including OSHA 30-hour certifications and a Site-Specific Safety Program. Bid submissions require electronic delivery through OC SAN’s Vendor Portal with specified PDF formatting standards, while bid security must be physically delivered to the district’s headquarters. Key deliverables include calibrated instrumentation, certified test reports, documentation of system integration, and training materials. The contract enforces clauses covering termination, changes, disputes, warranties, payment controls, subcontracting flow-downs, and value engineering incentives, all governed by California law. Offerors must comply with state-specific certifications regarding Iran contracting, CARB vehicle emissions, and Cal/OSHA reporting thresholds, with non-compliance potentially leading to disqualification or post-award obligations.
