Vehicle overview

The Alliant 2 Governmentwide Acquisition Contract is a GSA-managed governmentwide acquisition contract that gives federal agencies access to enterprise-level information technology capability across the federal government. It covers a broad spectrum of IT work — for example cloud and virtualization, cybersecurity and network operations, software and web application development, data analytics, mobile application development, modeling and simulation, sensors/RFID, and related IT labor categories. GSA lists the program ceiling at $90.75 billion; the master contract period began July 1, 2018, with a five-year option through June 30, 2028, and task orders may extend through June 30, 2033. Alliant 2 functions as a primary governmentwide IT vehicle with a large, publicly listed pool of contract holders and provisions to maintain competition and contractor engagement throughout the contract term.

The master contract establishes Standard IT Service Labor Categories (LCATs) and also allows Non‑Standard and Ancillary LCATs to be added; specific functional areas named in the master contract include mobile-centric application development, virtualization, network operations and infrastructure, web hosting and web application maintenance, sensors and RFID, and modeling and simulation. The contract is available to federal agencies and explicitly requires substantial subcontracting opportunities for small businesses, including veteran‑owned, service‑disabled veteran‑owned, HUBZone, disadvantaged, and women‑owned small businesses.
