About this file
This is an electrical reflected ceiling plan drawing for Portland International Airport's Terminal and Concourses Wayfinding Signage project (PDX 2026-512) in Oregon. The drawing, prepared by PAE Engineers, details the electrical infrastructure requirements for Concourse D's enplaning sector 53, specifically addressing connections and installations for wayfinding signage systems. The project involves connecting new blade signs to existing circuits, extending circuits to new surface mount or suspended signs with concealed accessible junction boxes and MC cable whips, relocating beam detectors to maintain functional alignment, and connecting new sign digital modules. The electrical work includes DMX cable routing between signs from an ETC DMX controller gateway, daisy-chain connections between multiple signs, and 0-10V wiring extensions to sign drivers. All conduit routing is required to be concealed with patching and painting as necessary, except where extending to suspended signs.
The drawing is dated August 2026 and was last updated on July 24, 2026, bearing the professional seal and approval of registered professional engineer Grant R. Parthemer (Oregon PE #44775, expiring December 31, 2026). The reflected ceiling plan scale is 1/8 inch equals 1 foot, and the drawing references additional specifications and cable routing details contained in other project documents, including typical cable routing details for suspended signage. The work encompasses multiple electrical connections, circuit extensions, and infrastructure modifications throughout the specified concourse sector to support the airport's wayfinding signage installation and upgrade initiative.
