The Professional, Scientific, and Technical Services Program (ProTech), managed by the Acquisition and Grants Office (AGO) consists of Indefinite Delivery, Indefinite Quantity (IDIQ) multiple award contracts organized into four Domains that align with NOAA's main missions: Satellite, Fisheries, Weather, and Oceans. ProTech is a mandatory-use vehicle for NOAA Line and Staff offices procuring professional, technical, and scientific services. Where applicable, ProTech may also be used by other Bureaus within the U.S. Department of Commerce (DOC). Each ProTech Domain IDIQ contract has a two-year base period of performance, and three one-year option periods of performance, for a total term of five-years if all options are exercised. Each Domain IDIQ contract will have a Small Business Reserve feature, will be awarded on a staggered timeline, and allows for task orders to be issued on a Firm Fixed Price (FFP), Cost Reimbursement, Time and Materials (T&M), Labor Hour (LH), or hybrid basis. The ceiling for all task orders is capped at $3,000,000,000 across all four Domains.
