About this file
This file is a Civil Abbreviations, Linetypes, and Symbols reference document prepared for the Portland International Airport North Runway Rehabilitation project located in Oregon. The document serves as a general legend and design reference guide dated October 2026, providing standardized symbology and abbreviations for civil engineering drawings related to the runway rehabilitation work. The sheet includes graphic scales for reference and notes that existing utility feature symbols and lines are depicted as they would appear on a 1" = 50' scale drawing, with existing utilities shaded and new utilities shown in bold to differentiate between current infrastructure and proposed additions.
The document contains comprehensive symbol legends for civil utilities, electrical utilities, and site and safety features commonly encountered in airport infrastructure projects. The legend covers elements such as manholes, catch basins, storm sewers, water lines, sanitary sewers, natural gas lines, airfield fuel systems, communications lines, electrical lines, and various site features including runway safety areas, taxiway object free areas, and wetlands. The reference guide is intended to ensure consistent interpretation of construction drawings across all project documentation and includes specifications for line types, grading contours, and other technical representations necessary for the design and construction coordination of the North Runway Rehabilitation project at Portland International Airport.
