About this file
This is a reflected ceiling plan for electrical work related to the Portland International Airport Terminal and Concourses Wayfinding Signage project in Oregon. The drawing, dated August 2026, depicts Concourse C enplaning sector 73 and specifies electrical connections and installations required for wayfinding signage throughout the concourse. The project involves connecting new blade signs and gate signs to existing circuits, extending circuits to new surface mount or suspended signs, and installing DMX cable connections between signs from an ETC gateway controller. The work requires concealed conduit routing, accessible junction boxes, and transitions to MC cable whips into signs, with patching and painting as needed. The design is prepared by PAE Engineers (Portland, OR) and approved by Grant Parthemer as of July 24, 2026, with an expiration date of December 31, 2026.
The electrical specifications indicate connections to ETC DMX controllers furnished with signage and daisy-chaining of DMX cables between signs from a four-channel ETC gateway located in the concourse. The plan references additional documentation including demolition plans, floor plans for gateway location specifications, and typical cable routing details on sheet E5.001 for suspended signage. All new or extended circuits must have concealed conduit with appropriate patching and painting. The drawing is part of a larger MEP (mechanical, electrical, plumbing) design package for the wayfinding signage project and serves as a guide for electrical contractors executing the installation work within the specified sector.
