About this file
This is an electrical symbol legend and abbreviations document prepared for the Portland International Airport Customs and Border Protection Improvements - Phase 2 project in Oregon. The document, dated September 2026, serves as a reference guide for electrical design drawings and includes comprehensive abbreviations for electrical components, systems, and terminology commonly used in construction specifications and plans. The file provides standardized notation for circuit elements, equipment callouts, conduit and conductor specifications, and mechanical equipment connections. The document establishes general notes regarding lighting branch circuits, receptacle circuits, exit sign wiring, dimming conductors, and elevation height measurements to ensure consistency across all electrical design sheets.
The document was prepared by M. Henning (design), E. Close (drawn), and B. Perry (checked), with Benjamin Earl Perry serving as the professional engineer of record (license #86683, expiration 12-31-2026). No specific pricing, contract terms, set-asides, or award information is contained within this technical reference document. The file functions as a standard legend and abbreviations sheet for the electrical design package and does not include procurement details, bid responses, or contractual requirements related to the broader airport improvement project.
