About this file
This is a Civil Utility Removal and Adjustment Plan prepared for Portland International Airport in Oregon, specifically detailing utility modifications required for the North Runway Rehabilitation project. The plan addresses utility adjustments along Runway 10L-28R, covering the section from Station 251+00 to Station 262+00, and was developed in October 2026 as part of design project PDX 2026-501. The document provides technical specifications for utility work including removal, replacement, and adjustment of existing infrastructure to accommodate runway rehabilitation grading and construction activities.
The plan identifies specific utility assets requiring modification through a utility adjustment table that designates each structure with status codes indicating whether adjustments are necessary (ADJ), structures require removal and replacement at current location (RAR), or no adjustment is required with retention and protection in place (NAR). A cleanout structure (STSCO0002810) is specifically noted for removal of its top and cover to facilitate grading work, with sealing requirements to prevent debris entry during construction and subsequent reinstallation at the finished elevation. The drawing was prepared by HNTB Corporation and signed by registered professional engineer Hans N. Conradt, with design oversight from Gene Tupper and C. Eiseler, establishing the technical baseline for utility coordination during the runway rehabilitation execution phase.
