DHS OPO intends to solicit and award an extension of support services as a sole source Task Order modification to APCO International Inc. 351 N Williamson Blvd. Daytona Beach, FL 32114. This is a notice of intent to solicit and award a sole source contract under the authority of FAR 6.103-1 “Only one responsible source and no other supplies or services will satisfy agency requirements”. The relevant NAICS code is 541715 Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology), with a size standard of 1,000 employees. The PSC code is R425, Support-Professional: Engineering/Technical. Summary of the requirement Background Project 25 (P25) is a suite of standards that enables interoperability among digital two-way land mobile radio communications products created for use by public safety professionals. The U.S. Department of Homeland Security (DHS) Science and Technology Directorate (S&T) partnered with the Department of Commerce Public Safety Communications Research program to establish the P25 Compliance Assessment Program (P25 CAP). P25 CAP is a formal, independent process for ensuring communications equipment declared by the supplier actually is P25 compliant and tested against the standards with publicly published results.

Compliance testing concludes with official summary test reports and suppliers' declaration of compliance, which are available to first responders. Scope First, the contractor shall provide technical support for the P25 CAP for DHS including review and development of Compliance Assessment Bulletins as well as evaluation of submitted test documentation. Second, the contractor shall work with DHS to enhance the efficiency and effectiveness of the P25 CAP in various areas including P25 Feature Gap Analysis follow-on efforts and supporting interoperability efforts in the communications domain.
