Scenario: I work at a federal agency, e.g., EPA, and am interested in having an "external" Government person, e.g., a H&HS employee, be an evaluator on a competitive procurement being conducted for R&D work. I'm being advised in order to do this, an interagency agreement (IAA) would need to be accomplished and adhere to the terms in FAR Subpart 37.2 Advisory and Assistance Services - specific emphasis on the determination of 37.204. This Subpart (37.2) states it prescribes "policies and procedures for acquiring advisory and assistance services by contract". Further, FAR Part 2 definitions states, in part, "advisory and assistance services means those services provided under contract by nongovernmental sources". Does FAR Subpart 37.2 apply to IAAs for something like this (use of a Government employee from 1 federal agency to perform as an evaluator on a competitive procurement for another federal agency)?
