About this file
This is a technical drawing document prepared for the Portland International Airport in Portland, Oregon, detailing guidance sign installation plans for the North Runway Rehabilitation project (PDX 2026-501). The document, dated October 2026 and prepared by design firm staff including Gene Tupper, M. Tieaskie, M. Dettmer, and registered professional engineer J. Nelson (PE #15521, expiration 12/31/2026), provides electrical installation guidance for multiple sign pad locations designated A4-6, A4-9, A4-12, and A4-13. The installation plans include scale drawings at 1" = 10' depicting the locations and configurations for four separate guidance sign installations across the airport's north runway area.
The technical specifications outline five key installation tasks: installation of new photofill (PF) guidance signs on existing foundations with power connection modifications, replacement of ground conductors and ground rods with new 3/4" x 10' rods and inspection covers using P-606 sealant, and replacement of sign panels on various sides of existing sign enclosures per detailed sign schedules on sheets E7.04 and E7.05. The document emphasizes that existing sign enclosures and electrical connections are to remain in place, with work focused on component upgrades and modifications. The drawing file was digitally signed on October 8, 2026, and references related electrical and grounding details contained in sheet E7.02 of the project documentation.
