These engineering design documents are from the Oregon Department of Transportation (ODOT) for the Major Bridge Maintenance Viaduct Project, specifically detailing the Pier 2 Dolphin Replacement Project located on the Yaquina Bay Bridge in Oregon. The project involves replacing existing dolphin structures (bridge support structures) with new steel dolphins, including detailed plans for pier protection, navigation light access ladders, and light mounting details. The documents provide comprehensive technical specifications for construction, including materials requirements (such as ASTM grade steel, stainless steel components, and specific bolting standards), precise dimensional drawings, and a construction sequence for removing existing dolphins and installing new navigation infrastructure.

The design plans cover multiple technical aspects, including pier protection strategies, dolphin elevation details, steel band specifications, and navigation light access ladder configurations. The project is scheduled for implementation in February 2025, with contract renewals extending through 06-30-2026. Technical specifications include requirements for steel piping, navigation light mounts, sacrificial anode connections, and precise positioning of structural elements. The design emphasizes maintaining navigational capabilities during the replacement process, with specific notes about preserving existing timber fender systems and installing new navigation lights and ladders to meet engineering standards.
