NOAA intends to award a sole-source purchase order to BAE Systems Information and Electronic Systems Integration Inc. of San Diego, CA for software license and support renewal. The justification is that BAE is the only manufacturer and distributor of the proprietary SOCET GXP and SOCET SET software, which provides unique, essential tools for 3D coastal mapping and data processing. Firms believing they can meet the requirements may submit substantiating documentation in writing to the point of contact within 15 days of this notice's publication. The government will evaluate any submissions solely to decide whether to conduct a competitive procurement.
