About this file
This is a pavement marking details drawing for the Portland International Airport North Runway Rehabilitation project in Oregon, prepared by HNTB Corporation in October 2026. The document provides technical specifications and visual details for runway and taxiway markings at Portland International Airport (PDX). The project specifications include standard taxiway centerline markings with enhanced centerline requirements for 150 feet prior to runway holding position markings, taxiway edge and shoulder markings in yellow (6 inches to 12 inches wide), runway threshold markings in white with specific stripe configurations (one, two, and three stripe options), and runway touchdown zone markings. The markings are to be installed on Runway 10L-28R with typical spacing intervals of 75 feet and coordinate layout line requirements. Design specifications call for black non-reflective backgrounds on permanent installations only on concrete pavement or existing asphalt surfaces. The drawing was completed on October 6, 2026, and is sealed by Oregon registered professional engineer Hans N. Conradt (License No. 60434PE, expiration date December 31, 2027).
The technical drawing references marking plans for precise location and installation guidance and includes scale details for taxiway centerline markings, runway touchdown zone markings, runway threshold markings, and taxiway centerlines through threshold areas. Station control points are provided on marking plans for runway edge stripe installation. The document was prepared by design engineer Gene Tupper, drawn by C. Eiseler, checked by N. Chowdhury, and reviewed by H. Conradt. The drawing specifies that sheet size reduction of 50 percent applies when printed on 11" x 17" format, and includes reference graphics for optimal viewing and printing of drawing content.
