This rule amends various provisions of the HUD Acquisition Regulation (HUDAR). These provisions include incorporation of several clauses and associated additions to the HUDAR matrix, replacement of references to Government Technical Representatives (GTRs) with references to Contracting Officer's Representatives (CORs), codification of deviations approved by HUD's Chief Procurement Officer (CPO) and minor corrections to clauses, provisions, and the HUDAR matrix. This final rule follows a proposed rule published on April 9, 2018 and implements the proposed rule without change except to remove obsolete definitions.
