The Navy seeks to procure one additional OrcaFlex software license from Orcina, along with yearly maintenance and technical support for eight existing licenses. This is a sole-source procurement justified under FAR Subpart 6.103, citing that only one responsible source can provide this highly specialized service. It is a DoD follow-on contract intended to avoid substantial duplication of cost to the government. This is not a request for competitive proposals, and no solicitation will be made available. Any responses will only be considered for future procurement planning purposes.
