The Drug Enforcement Administration (DEA) intends to award a sole source purchase order to GTP STRUCTURES I LLC for antenna site usage at the John Hancock Tower in Boston, Massachusetts. This procurement is critical for establishing access rights to locations necessary for installing antennas that support DEA communication networks, which are vital for the agency's operational efficiency. The DEA has issued a Class Justification for Other than Full and Open Competition, indicating that these services are available from only one source due to the unique requirements for optimal antenna placement, with an expected aggregate value of $18.5 million over five years. Interested parties who believe they can meet the requirements are invited to submit their information to Robert Radke at robert.j.radke@dea.gov by the archive date of this notice, although the government is under no obligation to acknowledge receipt or provide feedback on submissions.
