Description

The California Department of Transportation (Caltrans) is seeking contractors to provide on‑call, as‑needed positive location (potholing) services for underground utilities throughout Ventura County. Bidders must furnish all labor, tools, equipment, traffic‑control resources, and reporting required to locate utilities safely and efficiently, and must hold appropriate CSLB licenses (Class A or C‑12, and C‑31 for traffic control). The contract will be a three‑year, on‑call arrangement with a total estimated value of roughly $600 K, and includes small‑business and DVBE preferences. • Scope includes vacuum/hydro excavation (first 6 ft per site), additional linear feet, probing, electronic detection, CCTV inspections, traffic‑control planning, back‑filling, and detailed reporting (GPS, photos, video). • Mandatory licenses: CSLB Class A or C‑12, CSLB C‑31 (traffic control), and DIR registration; also required certifications for civil rights, Darfur Act, prevailing‑wage, and insurance. • Payment is unit‑price based; special provisions (railroad permits, encroachments, etc.) capped at ≤ 10 % of contract value. Small‑business preference up to $50 K and DVBE participation minimum 3 % with incentives. • Bids must be submitted by 2:00 PM on July 28 2026; bid opening at 2:30 PM same day; award expected August 4 2026; contract commencement Oct 1 2026, ending Sep 30 2029.

Budget estimate

$500,000 – $700,000

The addendum states an estimated contract value of $600,000. Considering typical unit‑price rates for vacuum excavation, traffic control, and reporting, the final award could range from roughly $500,000 (if lower‑priced bids dominate) to $700,000 (if additional reimbursable items and DVBE incentives are applied). Factors influencing the range include the number of on‑call service requests, mileage/travel costs, and the extent of special‑provision reimbursements (railroad permits, encroachments, etc.).
