Twenty-nine contractors have earned spots on the General Services Administration’s Alliant contract. GSA announced the winners today.

GSA had been working on Alliant for several years. The agency has not yet awarded Alliant Small Business, a companion contract to Alliant. That could come as late as the end of the year, according to John Johnson, assistant commissioner of integrated technology services at GSA.

However, Alliant contractors must award at least 50 percent of their subcontracting dollars to small businesses, he said.

The 29 winners will now compete with each other for task orders.

In all, 66 companies submitted bids for Alliant, said Jim Ghiloni, GSA’s Alliant program manager. The contract spans a five-year period with one five-year extension option, and has a ceiling of $50 billion.

Unlike some contracts, Alliant has off-ramp and on-ramp provisions so that companies can be removed from it or added to it over the 10-year course.

“This would allow us to re-open the solicitation and make new awards somewhere along the line,” Ghiloni said. “That allows us, should we choose, should the market change in some significant ways, to refresh the providers we make available through Alliant.”
