RFQ for Design-Build Project - Underbay Waterline Crossing

Background
The City of Newport is seeking qualifications for a design-build project involving the Underbay Waterline Crossing. This project is critical as it provides the only potable water source for the South Beach District, running a 12-inch ductile iron (DI) waterline under Yaquina Bay. The existing pipeline, installed in 1973, crosses a fault line, creating a significant vulnerability to water supply in case of a line failure. The goal of this contract is to design and construct a new waterline that enhances system resilience and reliability.

Work Details
The project involves the following key tasks:
1. Conducting a geotechnical analysis of the site, which is approximately 40 feet deep under the Bay.
2. Performing a marine environmental evaluation and acquiring all necessary permits for construction activities.
3. Acquiring land and easements required for the project.
4. Preparing soil specifications for boring operations and developing a 'frac-out' plan to manage potential drilling fluid releases during horizontal directional drilling (HDD).
5. Designing redundant control, monitoring, and backflow protection systems while considering tidal flow impacts on high tide profiles.
6. Construction will include boring a new 12-inch high-density polyethylene (HDPE) water pipe approximately 4,300 feet from Port of Newport property to the Hatfield Marine Science Center, connecting it to existing water lines on both sides of the Bay. The existing DI pipe will remain operational as a backup until deemed unsafe.

Period of Performance
The total time to complete the project is estimated at 29 months, divided into two phases:
- Phase 1 (Design): 18 months including land acquisition and permitting.
- Phase 2 (Construction): 12 months followed by a 2-month project close-out period.

Place of Performance
The work will be performed in Newport, Oregon, specifically under Yaquina Bay between McLean Point and the south end of the Hatfield Marine Science Center.
