The U.S. General Services Administration (GSA) has granted global information technology giant Unisys an indefinite-delivery, indefinite quantity Government-Wide Acquisition Contract (GWAC) to compete for task orders under the agency’s Alliant contracting vehicle.

Alliant, a 10-year vehicle with a $50 billion ceiling, is the largest single IT contract the federal government has ever issued and covers the full range of information technology services to meet evolving government agency needs. Unisys is one of 59 companies granted an Alliant contract.

Alliant will replace GSA’s ANSWER and Millennia IT services GWACs, which expire this year. Unisys currently holds a Millennia contract.

Alliant contract holders, including Unisys, will be able to select and manage partners and subcontractors in the context of accessing and providing the best and most current business processes and technologies to government clients.
