C5613488-D - Oxidation Ditch Aerator Maintenance and Repair Services

The California Department of Corrections and Rehabilitation (CDCR) is requesting bids for oxidation ditch aerator and mixer maintenance and repair services at the California Men's Colony wastewater treatment facility in San Luis Obispo, with bids due September 25, 2026 at 11:00 a.m. and public bid opening on September 28 at 2:00 p.m. The state has committed to a 25 percent small business participation requirement and is offering a 5 percent small business preference (up to $50,000) and a 3 percent Disabled Veteran Business Enterprise (DVBE) incentive (subject to a maximum of 5 percent and not exceeding $500,000).

The scope encompasses one-time scheduled services—inspection, maintenance, and repairs for oxidation ditches #1 and #2, and inspection, repair, and replacement of a damaged rotor for aerator #3—plus as-needed hourly maintenance (estimated 100 hours) and emergency repair services (estimated 50 hours). The state estimates $500,000 in emergency service costs but no fixed contract value is stated. All work must be performed during business hours (7:00 a.m. to 4:00 p.m., Monday through Friday, excluding weekends and state holidays) unless otherwise agreed, and the contractor must respond to emergency requests within 24 hours. Work is guaranteed for a minimum of 90 days and must comply with prevailing wage requirements under California Labor Code Section 1774.

The contractor must hold a valid California Contractors State License Board "A" General Engineering Class license and maintain a California business license or equivalent. The contract term extends through September 30, 2029. Bidders must submit rates on Exhibit B-1 for one-time services, hourly as-needed maintenance, and hourly emergency services; failure to bid any item results in rejection or commitment to perform at no cost. An optional walk-through is scheduled for September 15, 2026 at 10:00 a.m. Letters of inquiry are due by September 18, 2026. In event of tie bids, the highest early-payment discount (minimum 1 percent for invoices paid within 30 days) may be used as a tiebreaker.
