Field Service Management Services 3.12 Areas [3A/4A]_ [5A/8A]_1D_2D [4D/5D] [3S/5S] [4S/6S]

Agency: DEPT OF DEFENSENotice ID: JA_26_30Location: Atlanta, GA, 30303, USA
NoneJustification

HUD's Office of Single-Family Housing, Office of Single Family Asset Management has a need of unusual and compelling urgency to continue Field Service Management (FSM) services under FAR Overhaul 6.103-2 Other than Full and Open Competition (previously 6.302-2) to provide services for a base period of 12 months and 1 (one)- 12-month option period and the Option to Extend Services as per FAR Clause 52.217-8, for 6 (six) months. This is a hybrid (Fixed-Price and Cost Reimbursable Contract) Indefinite Delivery/Indefinite Quantity contract, as defined at Subpart 16.504 of the Federal Acquisition Regulation and in Section I, Clause 52.216-22, Indefinite Quantity, herein. Services provided by the Contractor under the contract shall be obtained as stated in HUDAR 2452.216-78, Ordering Procedures. The 3.12 Field Service Management Contracts are currently in option year 2. The current base contracts expire on November 1, 2026, and the current option 2 task orders ordering periods expire on February 15, 2027. Despite having remaining options for years 3 and 4, the Agency has concluded that it is in the Government's best interest not to exercise the next option for these areas due to the lack of performance resulting in: key vendors suspending operations because of outstanding client invoices, lack of property preservation and maintenance triggering property liens and blocking the marketing or sale of homes, and non-payments escalated to Congressional inquiries, putting the Agency's reputation and funding at risk.
