About this file
This is an electrical one-line diagram for the Portland International Airport Terminal and Concourses Wayfinding Signage project in Oregon. The drawing, dated August 2026, was prepared by PAE Engineers and depicts partial electrical distribution schematics for the project, specifically showing busduct configurations, unit substations, and associated electrical components. The diagram illustrates three separate one-line diagrams detailing busduct systems 4B0C-4CCA and 4B0C-4CCB, each operating at 1000A with 480Y/277V three-phase, four-wire specifications, along with tunnel roof bus plugs, mezzanine connections, and related electrical infrastructure serving the deplaning and enplaning areas. The drawing was approved on July 24, 2026, and includes design specifications prepared by G. Parthemer, P. Marks, and D. Peek under the direction of Jay Ostlund, with professional engineering oversight from licensed Oregon engineer Grant Parthemer (PE #44775).
The document is a technical schematic supporting the broader wayfinding signage project at Portland International Airport and does not contain contract pricing terms, set-asides, incumbent information, or funding details. As a design drawing rather than a procurement document, it serves as a reference specification for electrical contractors and demonstrates the technical requirements for power distribution systems that will support the terminal wayfinding signage installation throughout the concourses and terminal building areas.
