The Army Contracting Command seeks contractor support for a Unidirectional Hydrant Flushing and Repair Program at APG South (Edgewood) and the Adelphi Laboratory Center. The contractor must perform all tasks to execute the flushing program and produce associated documentation. This acquisition uses a two-step process: first, submission and evaluation of technical proposals without pricing, followed by an Invitation for Bids for accepted offerors. Award is contingent on the availability of appropriated funds, and the government may cancel the requirement at any time. No specific budget amounts, submission timelines, or bid deadlines are mentioned.
