About this file
This is a reflected ceiling plan with electrical demolition details for Portland International Airport, prepared by PAE Engineers on behalf of the Terminal and Concourses Wayfinding Signage project in Oregon. The drawing, dated August 2026, depicts Concourse D in the enplaning area, Sector 53, and specifies electrical work related to wayfinding signage installation. The plan identifies four primary demolition tasks: disconnecting an existing blade sign while retaining its circuit for a new sign in the same location; disconnecting an existing surface-mounted sign and retaining its circuit for extension to a new location; disconnecting and demolishing an existing surface-mounted sign circuit back to its source or last upstream device; and relocating a fire alarm beam detector while retaining its existing circuit for extension. The drawing is scaled at 1/8 inch equals 1 foot and includes a key plan for reference.
The document includes two critical notes addressing contractor responsibilities during demolition work. Where devices or connections are removed, the contractor must provide conduit and wire to maintain connectivity to all downstream devices that remain operational. Where circuiting is removed completely back to the relay and breaker, those components must be marked as spare. The drawing was prepared by G. Parthemer and reviewed by P. Marks, D. Peek, and Jay Ostlund, with the document expiring on December 31, 2026. The drawing number is E1.753, part of project 2026-512, and includes the standard CAD reference information for the wayfinding signage project at Portland International Airport.
