GAO’s Bid Protest Sustain Rate Soars, but Is There a Catch?

Client Alert | 24 min read | 11.06.23

On October 26, 2023, the U.S. Government Accountability Office (GAO) released its Annual Report on Bid Protests for Fiscal Year 2023.

The total number of protests filed and the number of protests sustained by GAO increased significantly compared to Fiscal Year 2022—and GAO’s “Sustain Rate” jumped to 31%.  GAO downplayed these increases to a degree, highlighting that it received “an unusually high number of protests challenging a single procurement”—the Department of Health and Human Services’ award of Chief Information Officer-Solutions and Partners 4 (CIO-SP4) government-wide acquisition contracts—which resulted in over 100 sustained protests.  Nonetheless, even excluding the CIO-SP4 protests, it appears that GAO’s “Effectiveness Rate” (the percentage of cases in which the protester received relief, such as voluntary corrective action or a GAO sustain) was comparable to prior years—at or near 50%.  Thus, bid protests remain an important oversight mechanism for the federal procurement system.

The most prevalent grounds upon which GAO sustained protests in FY 2023 were (1) unreasonable technical evaluations; (2) flawed selection decisions; and (3) unreasonable cost or price evaluations.  The most prevalent grounds for sustained protests over the past ten years are detailed in the table below:

GAO’s full statistics for FY 2023 are shown below:

Steel Tariffs Doubled: How the Hike Could Reshape Construction Projects at Home and Abroad

To date the Trump Administration has issued multiple proclamations imposing varying rates of import duties on steel and aluminum and certain derivatives, including construction materials. These measures have added volatility and financial pressures to the construction sector both in the United States and abroad. Most recently, on June 3, 2025, President Donald Trump issued a proclamation under Section 232 of the Trade Expansion Act of 1962, doubling tariffs on imported steel and aluminum from 25% to 50%, effective June 4, 2025. This action aims to counteract the continued influx of lower-priced, excess steel and aluminum imports that, according to the administration, threaten U.S. national security by undermining domestic production capacity. The proclamation notes that while prior tariffs provided some price support, they were insufficient to achieve the necessary capacity utilization rates for sustained industry health and defense readiness. The United Kingdom remains temporarily exempt at the 25% rate until July 9, per the U.S.-U.K. Economic Prosperity Deal....
