The Department of Defense, through the Washington Headquarters Services, intends to issue a sole source contract to Cummins Sales and Services for the repair, maintenance, and software support of the Cummins Human Machine Interface (HMI) Touchscreen. This procurement is essential to ensure the continued functionality of the proprietary system installed at the Raven Rock Mountain Complex, as Cummins is the only authorized service provider capable of performing these services without voiding the existing service agreement. The contract will cover a 12-month base period with four additional option periods, following the guidelines of FAR 13.106-1(b)(1) for single-source solicitation under NAICS code 811310.
