Contractors are readying to compete for a $7.2 billion Army program they expect to begin later this summer with the release of a request for proposals.

Army Intelligence and Security Command is preparing to issue the solicitation for its global intelligence services contract — which will span a broad range of tasks, from supporting the collection and analysis of intelligence to information technology development to administrative support.

The program is a follow-on effort to a much smaller contract, said Robert Grace, a research analyst at Herndon-based Deltek, which analyzes the government contracting market.

That program, which expires in August 2013, had a ceiling of $300 million and was awarded to three contractors: Invertix, L-3 Communications and Oberon Associates, now owned by CGI.

“The scope of the requirement has been significantly increased as well as the potential value,” Grace said.

The new program has a ceiling of $7.2 billion and is meant to provide “a more responsive acquisition vehicle for Army intelligence, security and cyber requirements,” an Army Intelligence and Security Command spokesman said.

Grace said it is expected to be awarded to 15 contractors — seven of which would be small businesses — but the Army said the exact number of awards has not been decided.

About 1,100 of Deltek’s users have marked the opportunity of interest, Grace said.

Despite industry reports of widespread contracting delays as the government copes with budget uncertainty, Grace said this program is still on track for a solicitation release in August.
