About this file
This is a technical drawing document prepared for the Portland International Airport (PDX) North Runway Rehabilitation project in Oregon, specifically detailing guidance sign installation plans and electrical specifications. The document, designated as Sheet E7.11 and Drawing Number PDX 2026-501, was designed in October 2026 and prepared by the engineering firm with involvement from Gene Tupper, M. Tieaskie, M. Dettmer, and registered professional engineer J. Nelson (Oregon PE #15521, expiration 12/31/2026). The project involves the installation of new CF sign foundations, PF guidance signs, CF ground rods with inspection covers, and associated electrical infrastructure including isolation transformers and 5KV conductors at multiple sign pad locations (A4-1, A4-2, A4-4, and A4-5) along the north runway. The drawing includes four scaled installation plans showing the locations and specifications for sign pad placements, with detailed cross-references to additional electrical sheets (E5.05, E5.07, E7.01 through E7.05) for comprehensive sign and electrical system details.
The document contains graphic scales for reference and is formatted for both viewing and printing optimization, with notation that the drawing scale is reduced 50% when sheet size is 11" x 17". The technical specifications reference specific components including L-867 signs with 12" diameter base cans, 24" deep installations, 3" extensions, 3/4" thick flange rings and cover plates, and 6.6/6.6A isolation transformers. Key notes on the drawing provide installation requirements at designated points and reference ductbank installations detailed on Sheet E4.22. The document was digitally signed on October 8, 2026, and includes standard engineering notation regarding electronic signature requirements for legal drawing validity.
