Replace culverts and inlets, place erosion control.

This Caltrans project calls for the removal and replacement of multiple culverts and inlet structures across Mendocino County, combined with the installation of erosion‑control measures. The work is purely civil‑construction, involving roadway drainage upgrades, and must be completed within a tight 30‑day construction window after award. Bidders must hold a California Class A or Class C‑42 contractor’s license and submit electronically by the bid‑opening date. • Replace existing culverts and inlets at several sites (5.6 mi east of Road 8152 to 3.0 mi west of Laytonville Dos Rios Rd). • Install erosion‑control solutions to protect the surrounding environment. • Complete all work within 30 working days; rapid mobilization required. • Estimated contract value $760,000 (estimate only). • Electronic bidding; no mandatory pre‑bid meeting or site visit noted.
