About this file
This is an electrical ductbank plan and profile drawing for the Portland International Airport North Runway Rehabilitation project in Oregon, prepared by registered professional engineer Jeffery L. Nelson. The drawing details the design and installation of electrical infrastructure along Taxiway A4, specifically showing the proposed ductbank alignment, existing and new electrical and communications manholes, conduit routing, and underground utility specifications. The project involves intercepting existing 4-inch PVC power conduits and 1-inch PVC communication conduits located 10 feet east of Manhole P-15/D-15 and extending them eastward in a new ductbank to new vaults at Manhole P-16/D-16. The design incorporates concrete-encased and direct-buried PVC conduits for both power and communication systems, along with corrugated innerduct installation between communication vaults. The plan and profile drawings are provided at scales of 1 inch equals 20 feet horizontally and 1 inch equals 2 feet vertically, with station measurements and offsets based on the Runway 10L-28R centerline alignment.
The drawing was designed in October 2026 and includes specific technical details such as existing manhole elevations, finish grade specifications, pavement structure composition (including asphalt concrete surfaces, aggregate base, and mechanical stabilization layers), and HDPE underdrain provisions. The document references related drawings for removal information (Sheet E2.09) and lighting information (Sheet E4.09), with additional detail sheets (E5.13 through E5.18) providing further specifications for the new electrical and communication manholes. The design specifies the installation of three corrugated 1-1/4-inch diameter innerducts using Carlon A6D2 or approved equivalent materials in the communication conduit between vaults. The engineer's professional registration number (15521PE) and expiration date (12/31/2026) are documented on the drawing.
