About this file
This is a Rebuild ATON (Aid to Navigation) Oakland Harbor specification document detailing structural reconstruction requirements for navigation aids across multiple U.S. waterways, primarily in the Pacific Northwest region. The document, referenced as PSN 18866153, contains comprehensive technical specifications organized into base and option items spanning five operational bases.
The project encompasses the demolition and replacement of existing navigation structures with new steel pile configurations. Base 0001 items include seven navigation aids in the Cascade Rapids, Fashion Reef, Wind Mountain, and Stevenson areas, requiring conversion from wooden or mixed-material structures to multiple or single pile steel structures with varying tower heights (ranging from 5x5 to 7x7 configurations) and focal planes between 12 and 27 feet above Mean High Water. Base 0002 consists of 13 items in the Chinook Channel, Cathlamet Bay, and North Channel areas, predominantly converting buoys and wooden structures to single or three-pile steel structures with reduced headers. Options 0003 through 0005 contain additional items across Lake Wallula, Lake Umatilla, Hood River, Multnomah Falls, and other locations, with similar conversion requirements. Construction specifications include pile penetration depths of 30 feet below mudline, safety climb device installations, ladder extensions, dayboards, underwater work requirements, diving services, post-construction surveys, and photographic documentation. All structures require adherence to specified ATON standard drawings, with detailed notations addressing site-specific requirements including archaeological monitoring for certain Lake Wallula locations and eelgrass surveys for Chinook Channel items.
