Failure To Update Invalidates Evaluation And Responsibility Determination

In Greenleaf Constr. Co. (Jan. 17, 2006, http://www.gao.gov/decisions/bidpro/29310518.pdf), GAO held that the awardee's failure to advise the agency of changes to its proposed plan for performance which arose after submission of its final proposal revision, including different key personnel and a different software system, invalidated the technical evaluation based on the original proposal. GAO also invalidated the contracting officer's responsibility determination as to the adequacy of awardee's financial resources because the contracting officer knew that an affiliated company that had provided most of the revenues of the awardee's corporate family in the DCAA analysis had been sold.
