Notice of Intent to Sole Source - NIEHS Support Services for Epidemiology - Contract HHSN273201600003I- Extension of Ordering Period for IDIQ Contract and Increase to IDIQ Ceiling

The National Institutes of Health (NIH) is issuing a notice of intent to award a sole source contract modification to DLH, LLC for support services for epidemiology. The contract will be modified to extend the ordering period by 24 months and increase the IDIQ ceiling by $20,000,000. The purpose of this modification is to ensure continuity of mission-critical research while the NIH procurement team pursues re-competition of these services under a new full and open cost reimbursement contract. The contractor will provide specialized facilities, capabilities, and expertise critical to meet Division of Intramural Research (DIR) program needs, including research, managerial/programmatic, IT, and regulatory infrastructure for all ongoing studies and support services. • The contractor must work in a collaborative role, executing PI-directed analyses requiring long-standing trust, scientific alignment, and familiarity with EB decision-making norms. • The requirement of this contract explicitly references historical EB studies and stored biological samples, requiring prior knowledge of study lineage, consent constraints, and analytic decisions accumulated over many years. • The contractor is responsible for managing and monitoring stored biologic samples from historical EB studies, including reconciliation across repositories and legacy systems with functions inherently tied to the incumbent's custodial role. • The SOW mandates use and maintenance of existing databases, freezer monitoring systems, laboratory inventories, and study management systems, all of which are incumbent-operated and validated.
