Are you guaranteed a specific amount of work if you are awarded a contract?

No. These contracts do not commit funds, nor do they guarantee any amount. The contract capacity will depend on the number of firms selected in each category. Additionally, these contracts are not an authorization of work. Authorization of work and commitment of funds are made through task orders on an as needed basis. For the 2020 contracts, 48 total firms were selected, and approaching 50% of the available capacity was used, which equated to approximately $100M in task orders. Most task orders for the on-call contracts were awarded based on a subsequent mini-selection process.

How many firms are going to be selected per category?

The exact number of firms per category will be decided by the selection committee during the procurement process.

How are small businesses included?

In 2020, DOTI worked with the Division of Small Business Opportunity (DSBO) to determine contract goals to ensure small business participation. DSBO supports the growth, capacity, and sustainability of small, disadvantaged, minority, and women-owned businesses. The goals for the existing categories are available in our on-call contract dashboard. The goals for the 2026 contracts have yet to be determined.

I am looking to partner, any recommendations?
