About this file
This is a reflected ceiling plan electrical drawing for the Portland International Airport's Terminal and Concourses Wayfinding Signage project (PDX 2026-512). The drawing depicts electrical connections and lighting requirements for Concourse C Enplaning Sector 71 wayfinding signage installations. The project involves connecting new blade signs, gate signs, and suspended signage to existing electrical circuits, with provisions for DMX-controlled lighting systems managed through an ETC DMX controller and gateway system. The drawing specifies concealed conduit routing for all new or extended circuits, with junction boxes and MC cable transitions integrated into sign installations. The project document was prepared by PAE Engineers in Portland, Oregon, with design oversight provided by Jay Ostlund and technical coordination among multiple team members, with final approval dated July 24, 2026.
The electrical specifications outlined in the reflected ceiling plan establish technical requirements for sign connectivity and control systems integration across the concourse sector. Key installation requirements include connecting un-switched line voltage to ETC DMX controllers furnished with signage, daisy-chaining DMX cables between signs from a 4-channel ETC gateway, and extending 0-10V wiring to sign drivers as specified. All circuit extensions require concealed conduit with patching and painting as necessary to maintain the terminal's finished appearance. The drawing references additional demolition and detail plans, including typical cable routing specifications documented on sheet E5.001, ensuring comprehensive coordination with the broader wayfinding signage project scope.
