1947 Watermain - North Bound Airport Expressway Preservation

The Port of Seattle’s Aviation Project Management Group is forecasting the restoration of a 1947 water main located along the northbound Airport Expressway using cured-in-place pipe (CIPP) technology under a Design-Bid-Build procurement model. The project aims to preserve the integrity of the aging infrastructure without excavation, leveraging modern rehabilitation methods to extend service life and enhance system reliability. The work will involve lining the existing pipeline with a resin-saturated fabric liner that is inverted and cured in place, minimizing disruption to adjacent roadways and surrounding facilities. The contract falls under NAICS code 237110, indicating it is classified as Water and Sewer Line and Related Structures Construction. Moraa Omwega serves as the primary point of contact for inquiries, with Ray Moreno designated as Project Manager. The solicitation was posted on July 31, 2026, and while no set-aside designation or bid deadline has been specified, interested parties are directed to the official Port of Seattle portal for updates and detailed technical requirements. The place of performance is tied to the Airport Expressway, although exact geographic coordinates are not provided, and all work must be coordinated with ongoing airport operations to ensure safety and minimize impact to airfield access and logistics.
