Strategic Services Sourcing (S3)

The Strategic Services Sourcing (S3) program is a multiple-award IDIQ contract that provides one-stop shopping for total life cycle services ranging from research to sustainment for the U.S. Army Communications Electronics Command (CECOM) under the Army Material Command. Contractor-provided services are required within three key functional areas: business operations, logistics and engineering. The S3 contract has a broad scope across all functional areas and a ceiling of $19.25 Billion. It is one of ManTech's 1,000 current contracts.

The S3 IDIQ vehicle was awarded in 2006, and the U.S. Army CECOM C4ISR community has used it to acquire a broad range of valuable support services. The Army’s intent in developing S3 is to give end users access to a variety of prime contractors and subcontractors that are capable of delivering the entire breadth of equipment and services that users might require. Now in the first year of the 5-year option period, this vehicle is also open to use by other agencies.

How to Use

Step 1 – Contact the S3 Acquisitions Center (U.S. Army Contracting Command-Aberdeen Proving Ground) to discuss service you may need.

Step 2 – The S3 Acquisitions Center Staff will assist the customer in developing the PWS: The S3 Acquisitions Center Staff will convert the customer’s input into a legal PWS document.

Step 3 – Finalize the PWS and transfer funding: The customer provides funding that will cover the estimated cost of the contractor performance and the administrative fee for the services provided by the S3 Acquisitions Center.

Step 4 – Prepare the Acquisition Package: The S3 Acquisition Center Staff will prepare the acquisition package and send it to the Contracting Officer.

Step 5 – Participating primes submit (by posting to the IBOP) their Technical & Cost Proposals for evaluation: The customer will evaluate the technical and cost proposals received, rank order them, and send their recommendations to the S3 Acquisitions Center, which will forward them to the Contracting Officer for approval. During this evaluation period, the S3 Acquisitions Center Staff will work directly with the Contracting Officer on the customer's behalf for all queries and procurement requirements.

Step 6 – The Contracting Officer Awards the Task Order: The customer and contractor are notified of the award, copies of the task order are distributed, and performance begins.
