About this file
This file is a technical drawing document produced by Portland International Airport for the Portland International Airport North Runway Rehabilitation project in Oregon. The document presents guidance sign installation plans and details, specifically addressing the removal, reinstallation, and electrical modifications required for portable field guidance signs at the airport. The project involves installing new PF guidance signs on existing foundations, replacing ground conductors and ground rods, and managing electrical circuits and isolation transformers. The drawings are presented at a scale of 1 inch equals 10 feet and include three sign pad locations labeled A2-1, A2-2, and A2-3. The design was completed in October 2026 with digital signatures executed by the responsible parties. The drawing number is PDX 2026-501 E7.14 with a design number of 277, and the document was submitted by Gene Tupper, drawn by M. Tieaskie, checked by M. Dettmer, and approved by registered professional engineer Jeffery L. Nelson (PE 15521), whose license expires on December 31, 2026.
The project specifications detail key construction procedures including the centerline alignment of new sign power legs with existing power connection openings, reuse of existing base cans and conduits where applicable, removal and safe storage of existing signs during paving work, installation of new 3/4-inch by 10-foot ground rods with inspection covers, application of P-606 sealant around covers and sawcut areas, and reuse of existing isolation transformers. The document serves as a technical reference guide for contractors conducting the rehabilitation work, with guidance notes provided for proper viewing and printing of the drawing content to ensure visibility of multiple shading planes necessary for complete visualization of the installation details.
