Construct sound wall, drainage, and electrical.

The California Department of Transportation is soliciting bids for contract 03-1N7504 to construct approximately 1,090 linear feet of sound wall along the WB 50 to NB 51 connector ramp on the outside shoulder embankment. The project scope also includes the replacement of the drainage system and luminaries, as well as comprehensive electrical work involving the modification of lighting systems, foundations, and conduits. The estimated cost of the plans is 1,621,297.00 dollars. Bidders must propose a completion timeline between 110 and 155 working days and submit bids on a cost-plus-time basis via the Bid Express website. Technical requirements specify the use of Basalite Concrete Products and stainless steel dowels, with strict adherence to California MUTCD and electrical safety orders. Quality control is emphasized through mandatory tensile testing of samples and the requirement for a welding QC manager registered as a civil engineer or certified CWI. Environmental compliance is critical, as soil from the first foot of excavation is classified as California hazardous waste due to lead concentrations. The contract requires a 500,000 dollar combined single limit general liability insurance certificate and adherence to prevailing wage rates. Additionally, the solicitation emphasizes small business participation, requiring detailed certifications for SBE and DVBE entities to meet specific participation goals.
