Modjeska Grade Road Domestic Water Pipeline Relocations

The County of Orange is undertaking the Modjeska Grade Road Street and Storm Water Improvements Project, which includes repaving, installing new curb and gutter systems, storm water inlets, swales, and retaining walls along Modjeska Grade Road from Santiago Canyon Road to Markuson Road. This construction necessitates the relocation of approximately 310 linear feet of existing domestic water pipeline owned by the Irvine Ranch Water District, specifically sections of 6 and 8-inch diameter pipe at six distinct locations. Concurrently, six isolation valves within the project corridor will be replaced, and any existing asbestos cement pipe encountered will be properly abated to comply with safety and environmental regulations. The work is coordinated to minimize disruption while ensuring the integrity and functionality of the water infrastructure during and after the road improvements. The Irvine Ranch Water District is managing the procurement process for this pipeline relocation, with the solicitation numbered 13238 and posted on June 30, 2026. Proposals are due by July 28, 2026, at 10:00 PM, and contractors are required to submit a bid bond amounting to 10% of the total bid. All work must adhere to the IRWD Construction Manual, including standardized drawings and technical specifications accessible via the district’s website under the Engineering section. The primary point of contact for inquiries is Brian Botello of the IRWD Engineering Department, who can be reached via email or phone. The project is classified under a SLED government entity, with performance taking place in California, and all bids must be submitted through the designated electronic portal.
