Underground Conduit Installation (Trenching & Boring)

The contract entails the installation of 72,300 linear feet of 1.5-inch high-density polyethylene conduit with a minimum 48-inch cover depth, requiring comprehensive earthwork including trenching and directional boring techniques to accommodate utility alignment and environmental constraints. Roadway crossings will be executed using 5-inch cased bore methods to ensure structural integrity and minimize surface disruption, with all work subject to precise engineering specifications for depth, material quality, and backfill procedures. This subcontract is issued under NAICS code 237110 for Utility System Construction and is associated with Caltrans District 2 in Redding, California, with the primary place of performance located in Dorris. The project is set to be publicly posted as of June 8, 2026, and involves delivering a robust subsurface utility infrastructure system that meets state transportation and environmental standards, emphasizing durability, safety, and long-term operational reliability without surface excavation impacts where feasible.
