The California Department of Transportation (Caltrans) is requesting bids for trenchless installation of reinforced concrete pipe on State Highway 15 in Riverside County under Contract 08-1L8204, with bids due November 10, 2026. The project carries a 5% Small Business Enterprise (SBE) participation goal and offers eligible bidders a choice between a 5% bid reduction (capped at $50,000) if certified as an SBE, or a non-small-business subcontractor preference requiring 25% certified SBE participation.

The scope includes trenchless installation of 30-inch and 48-inch reinforced concrete pipe; removal and abandonment of existing culverts; installation of drainage inlets and structures; erosion control; temporary traffic control; and site restoration. The work spans from 0.4 mile south of Indian Truck Trail Undercrossing to 1.1 miles north of Temescal Canyon Road Undercrossing Bridge. The contract requires either a California Class A contractor license or Class C-42 license. Environmental compliance provisions address regulated species protection, including nesting birds and Crotch's bumble bee, and require contractor-supplied biologists and noise monitoring. Stormwater pollution prevention, traffic control restrictions with liquidated damages for non-compliance, and prevailing wage rates (as determined by the California Department of Industrial Relations) apply.

The estimated project cost is $6.9 million with a 120 working-day completion timeline. Bids must be submitted on a unit price basis via Bid Express with bidder's security equal to at least 10% of the bid. The bid item list contains 69 items spanning pipe installation, structural concrete, temporary traffic control systems, environmental compliance, and landscaping. Contractors must submit environmental product declarations for concrete materials and designate an on-site safety representative with specified certifications. Prompt payment to subcontractors within 7 days of progress payment receipt is required.
