About this file

Written by GovTribe AI ·

This solicitation requests proposals for the detail design and construction of Class B vessels for the National Oceanic and Atmospheric Administration. Offerors are to provide all resources necessary to deliver two vessels with options for up to two additional vessels, including a crewed survey launch with each. The base vessels are to be delivered under firm fixed price contract line items, with options for recommended spare parts, additional government requirements support, initial outfitting materials, extra crewed survey launches, and special studies. Proposals are due by August 16, 2022. The work is to be conducted domestically with a small business size standard of 1,250 employees. Inquiries are due by June 17, 2022.
