Install trash capture devices, construct maintenance vehicle pullouts

The California Department of Transportation (Caltrans) is soliciting proposals under solicitation number 04-0W0604 for the installation of trash capture devices and the construction of maintenance vehicle pullouts across the state of California. The solicitation was posted on July 27, 2026, with a response deadline of September 1, 2026, and is classified under NAICS code 237310 for heavy and civil engineering construction. All work must be performed within California and is governed by Caltrans-specific Standard Specifications and Special Provisions rather than standard FAR clauses. Key deliverables include the removal of culverts in linear feet, placement of Class 2 aggregate base, application of prime coat and hot mix asphalt, street sweeping, and mobilization efforts. The contract includes detailed technical requirements for materials, including concrete with a compressive strength of 3.6 KSI and reinforcing steel at 60.0 KSI, all aligned with AASHTO LRFD design standards. Environmental compliance is strictly enforced, mandating Environmental Product Declarations for asphalt over 2,250 tons and concrete over 250 cubic yards, registered via DIME, with a $6,000 penalty for noncompliance. Off-road diesel equipment must meet Tier 4 Interim or Final emissions standards, and a complete inventory of such equipment must be submitted 15 days prior to use. Contractors must appoint a qualified Safety Representative with Cal/OSHA 30-hour or OSHA 510 certification and submit a Site-Specific Safety Program for approval. Payroll records must be submitted electronically via LCPtracker Pro, and compliance with Buy America and DVBE subcontracting requirements is mandatory, with DVBE quotes required and penalties applied for noncompliance. Traffic coordination with four other active Caltrans contracts is required even if not physically adjacent, and work is prohibited from encroaching on railroad property. Inspection and acceptance criteria are site-based, requiring ISO/IEC 17025-accredited labs to conduct contaminant testing, including pH above 5.0, soluble lead under 5 mg/L, and total lead under 80 mg/kg, with results analyzed using ProUCL at a 95% upper confidence limit and a chain of custody maintained. No contract value is provided due to missing pricing data, and while invoicing must go through Caltrans’s prompt payment monitoring system, no remittance details or payment office information are
