This final rule amends the U.S. Small Business Administration (SBA) regulations governing small business prime contracting assistance. Specifically, this final rule: revises the definition of contract bundling to expressly include multiple award contract vehicles and task and delivery orders under such contracting vehicles; mandates that procuring activities coordinate with the Small Business Specialist (SBS) on proposed acquisition strategies or plans contemplating awards above specified dollar thresholds, and that the SBS notify the agency's Office of Small and Disadvantaged Business Utilization (OSDBU) when those strategies include contract bundling that is unnecessary or unjustified; revises the threshold and documentation required for substantial bundling; and requires the agency's OSDBU to perform certain oversight functions. These amendments are intended to implement a number of the recommendations included in the October 2002 Office of Management and Budget (OMB) report entitled "Contract Bundling: A Strategy for Increasing Federal Contracting Opportunities for Small Business."
