IDIQ under an IDIQ - If could change the rules to allow it, how would you? in Schedules, GWACS, MACs, IDIQs Posted January 10 · Report reply @Hammspace, Harris IT Service Corporation, B-411699; B-411796, October 2, 2015, is the only case I know of where the issue of an "IDIQ under an IDIQ" was addressed. The test the GAO applied was whether the original task order contained the information required by FAR 16.505(a)(7). In that case, the GAO determined that the original task order did not. Therefore, they concluded that the task order was an improper IDIQ under an IDIQ. The auditor seems to be applying a different standard--probably one they thought up.
