03-4J9004 Construct Acceleration Lanes

The California Department of Transportation (Caltrans) District 03 is requesting bids to construct acceleration lanes on State Highway 5 in Sacramento County near Thornton under Contract No. 03-4J9004, a federal-aid project, with bids due August 25, 2026 at 2:00 p.m.

The scope spans construction from Lost Slough Bridge to Dierssen Road Overcrossing (Post Mile 1.2/3.1) and includes 74 bid items: earthwork, erosion control, asphalt concrete paving, traffic control systems, electrical systems, signage, pavement markings, and temporary construction elements. Bidders must hold either a Class A contractor license or a Class C-12 license constituting the majority of work. The project operates on a cost-plus-time basis with work to be completed within a bid range of 65 to 90 working days. Prevailing wages are mandatory, with contractors applying whichever rate is higher between California Department of Industrial Relations wage determinations and federal minimum wage. Buy America requirements apply to manufactured products and construction materials. Environmental product declarations are required for hot mix asphalt and concrete. Additional compliance mandates cover stormwater pollution prevention, local material testing and certification, treated wood waste management, and professional project partnering.

The estimated project cost is $5.4 million. Bidders must submit security equal to at least 10 percent of their bid amount. Liquidated damages for failure to open scheduled closures are limited to 5 percent of the total bid per occurrence, calculated at $1,531 to $3,062 per 10-minute interval depending on facility type and time period. Traffic control during construction requires maintaining at least one through lane open in each direction, implementing portable radar speed feedback sign systems, and complying with construction work zone speed limit reductions, with detailed lane closure restrictions by day and time for both mainline freeway and ramp operations.
