Contractors are awaiting three major contracting competitions soon to be released from the Department of Health and Human Services, the General Services Administration and NASA.

All three solicitations are government-wide acquisition contracts — or GWACs — a type of multiple-award contract gaining increasing steam in federal contracting. These programs set preassigned terms and conditions and limit orders for specific projects to a restricted set of pre-qualified vendors, giving government agencies more control.

These contracting programs can create a streamlined process and expedited awards. Winners also benefit from smaller competitions.

The three contracts soon to move forward offer $26.5 billion in potential federal IT and professional services dollars. Winning a place on one of these efforts can offer a great deal of potential business.

Here is a look at the soon-to-be-released GWACs:

Department of Health and Human Services’ Chief Information Officer Commodity Solutions

The CIO-CS contract, also known as the Electronic Commodities Store, will allow the National Institutes of Health and other federal agencies to buy IT that is already in production.

Deltek estimates a solicitation release in March for the program, which is worth up to an estimated $6 billion over 10 years. The predecessor program included 42 companies.

General Services Administration’s One Acquisition Solution for Integrated Services

OASIS is expected to include a range of professional services such as program management and consulting services, logistics services, financial services and professional engineering services.

The GSA has formed both unrestricted and small-business vehicles that will allow agencies to set aside task orders for direct award or limit competitions to specific kinds of small businesses.

The 10-year program is estimated to be worth $10 billion. The OASIS requirement is new and has no previous service providers. The government estimates a solicitation release during the summer; Deltek anticipates the solicitation in June.

NASA’s Solutions for Enterprise-Wide Procurement V

Like previous SEWP contracts, the fifth version is expected to provide goods and services related to computers, high-performance servers and database servers, mass storage and network devices, advanced video and visualization solutions, computer support devices and security systems and tools, among others.

The government estimates a solicitation release in June.

While the program’s estimated value was originally $5.6 billion, Deltek now estimates — based on the spending trends of predecessor contracts — the newest version will be worth at least $10.5 billion.

Fifty-two companies provided services under SEWP IV.
