About this file
This is a reflected ceiling plan electrical drawing for Portland International Airport's Terminal and Concourses Wayfinding Signage project, prepared for the State of Oregon. The document specifically details the electrical infrastructure requirements for Concourse C Enplaning Sector 72, including connections for new blade signs, gate signs, surface mount signs, and suspended signage. The drawing identifies five primary electrical work items, with keynotes specifying connection requirements such as linking new signage to existing circuits, extending circuits with concealed accessible junction boxes and MC cable whips, and reconnecting loads to panelboard breakers. The plan indicates DMX channel designations for signage controlled through an ETC DMX Controller and details daisy-chain DMX cable routing between signs from a 4-channel ETC Gateway located within the concourse. The document was prepared by PAE Engineers on August 2026 and bears the professional approval of Oregon Licensed Professional Engineer Grant R. Parthemer, valid through December 31, 2026.
The drawing reflects standard specifications for concealed conduit routing with associated patching and painting requirements for new or extended circuits. All DMX circuits are to be routed concealed except where extending to suspended signs, with reference made to typical cable routing details contained in drawing E5.001. The document includes standard graphic display guidance for optimal viewing and printing across three different shading levels and notes that the drawing scale is reduced 50 percent when printed on 17" x 22" sheet sizes. No pricing, set-aside information, funding sources, incumbents, or contract term details are presented in this technical drawing, which serves as a design specification document within the broader wayfinding signage project documentation.
