About this file
This is an electrical construction detail sheet for the Portland International Airport North Runway Rehabilitation project in Oregon, specifically addressing vaults and cable rack installations. The document, designated as Sheet E5.17 and prepared in October 2026, provides technical specifications and design details for securing splices to splice racks using black T&B ty-wraps within airport vaults. The sheet includes three detailed sections: a partial plan view of an existing typical 444LA vault (scaled at 3/4" = 1'-0"), a splice rack section view (scaled at 3/4" = 1'-0"), and a second splice rack section view at the same scale. The technical specifications indicate that new cable racks must be provided and installed per Sheet E5.16 mounting details, with embedded "C" channel construction measuring 4'-8" in height. The design accommodates conduit entrances with provisions to space or shorten stanchions as required for clearance, and the vault is depicted with the door open for visibility of the splice rack configuration.
The drawing was prepared under the professional engineering licensure of Jeffery L. Nelson (Oregon PE #15521), with an expiration date of 12/31/2026, and was digitally signed on October 8, 2026. The document was designed by Gene Tupper and M. Tieaskie, drawn by M. Dettmer, and checked by J. Nelson. The sheet is part of the larger PDX 2026-501 electrical details package for the North Runway Rehabilitation project and references related installation details and specifications contained on adjacent sheets, particularly Sheet E5.16 for rack mounting details. The drawing includes a graphic scale reference and notation regarding printing and viewing optimization for three different shading planes to ensure proper interpretation of the technical content.
