About this opportunity
The Port of Seattle is requesting bids for the 188th Ductbank Crossing project at Seattle-Tacoma International Airport, with proposals due July 21, 2026. The project will construct new empty power and communication ductbanks crossing South 188th Street to terminate adjacent to the South Substation, along with a new retaining wall to expand the Airport Operations Area. An Apprentice Utilization Requirement of 15% of total labor hours applies; a WMBE utilization goal of 7% is also in place.
The scope encompasses construction of new empty ductbanks, generator pads, and electrical equipment pads within the expanded area, as well as utility relocations and new utility work. The project explicitly excludes installation of communications or electrical cables and electrical equipment. The project manual (Volume 1 of 2, 52 MB) was posted June 22, 2026; bidders must reference both volumes and all addenda and specifications to prepare responsive proposals.
The work is performed at Seattle-Tacoma International Airport within King County and Spokane City jurisdictions in Washington State. No contract value, contract term, or incumbent information is provided in the source materials.
