The IX-527 barge will be included in the first task order (TO), awarded at the time of the IDIQ. Market Research is being conducted to determine all potential socio-economic small businesses and large businesses interested in, and capable of, providing the support services identified herein. The Draft SOW for IX-527 is being provided to solicit comments and questions from potential offerors and will remain posted until 1 April 2025.
