About this file
This is an electrical details drawing sheet for the Portland International Airport North Runway Rehabilitation project in Oregon, prepared by the airport's engineering team. The document provides technical specifications and installation details for elevated light fixtures and base can installations in asphalt concrete pavement along the runway shoulder. The drawing includes four detailed cross-sections showing typical elevated taxiway and runway edge light installations, with specifications for components including 2-inch PVC ground rods, 12-inch diameter by 24-inch deep base cans, 3/4-inch flange rings, extensions, and base plates. The installation details specify that base cans should be set with finish elevation 1/4 inch above adjacent grade, conduit should be positioned 24 inches below finish grade, and grounding systems should incorporate #6 bare copper conductors connected via exothermic weld to both ground rods and base cans. The drawing was designed and prepared in October 2026 by the airport's engineering staff and signed by registered professional engineer Jeffrey L. Nelson, with expiration date of December 31, 2026.
The drawing provides construction guidance for contractors, including requirements for saw-cutting asphalt concrete openings to install base cans, filling saw cuts with P-606 sealant, applying silicone sealant between flange rings and extensions, and maintaining proper spacing and alignment of conduits between base cans. Additional specifications address ground rod installation requirements, including 3/4-inch diameter rods measuring 10 feet long positioned minimum 12 inches from the base can with the rod top minimum 6 inches below finished surface. The document references related detail sheets and notes throughout the technical specifications to ensure comprehensive installation requirements are met.
