About this file
This is an electrical one-line diagram prepared by PAE Engineers for Portland International Airport, a division of the City of Portland, Oregon, supporting the Terminal and Concourses Wayfinding Signage project (PDX 2026-512). The document, dated August 2026, presents three partial one-line electrical diagrams detailing the power distribution infrastructure for the wayfinding signage installation. The diagrams illustrate busduct systems serving the project areas: Busduct D1 (800A, 480Y/277V, 3-phase, 4-wire), Busduct D3 (1000A, 480Y/277V, 3-phase, 4-wire), and Busduct D4 (1000A, 480Y/277V, 3-phase, 4-wire). The scope includes unit substations (TDA and TDB), distribution panels rated at 45KVA with 480V-208Y/120V transformation, and associated busplug connections serving deplaning tunnel mezzanine roof and enplaning areas. The drawing is prepared by D. Peek, drawn by P. Marks, checked by Jay Ostlund, and approved by Grant Parthemer, a licensed Professional Engineer in Oregon (License No. 44775PE, expiring December 31, 2026).
The document serves as a technical reference for electrical contractors performing work on the wayfinding signage project. All diagrams are presented at reduced scale for reference purposes only, with graphic scales provided for measurement verification. The electrical infrastructure depicted supports the terminal's operational requirements and integrates with existing airport systems in the terminal and concourse areas. No specific pricing, set-asides, funding amounts, or contract renewal terms are identified within this technical drawing document.
