About this file
This electrical detail drawing is part of the Portland International Airport North Runway Rehabilitation project in Oregon. The document specifies technical requirements for the installation of in-pavement lighting fixtures, including base can assemblies, flange rings, extensions, and conduit systems. The design outlines two primary base can types (L-867 and L-868) with varying diameter specifications ranging from 12 to 16 inches, along with detailed installation procedures for fixture mounting, reinforcing bar cage configurations, and sealant application. The drawing establishes mandatory specifications for stainless steel hardware, including 3/8" by 16 Type 304 hex cap bolts with anti-vibration washers and torqued to manufacturer recommendations. The document includes a reference table for 5KV connector kit capacity limits based on junction can volumes, restricting the maximum number of kits per single base can without express approval from the Port.
The technical specifications require contractors to provide shims at their own expense to meet final grade requirements, with a maximum of three shims permitted per installation. Conduit installation must extend 2 inches into the can after backfill and stabilization, with grommets furnished by the base can supplier. The drawing was prepared by Gene Tupper and M. Tieaskie, checked by M. Dettmer, and approved by J. Nelson, a registered professional engineer in Oregon. The document is dated October 2026 and carries design number 102981 and drawing number PDX 2026-501 E5.04, with a professional engineer stamp expiring December 31, 2026.
