Obtain a Delegation of Procurement Authority

OASIS+ DPA training registration is now open.

Visit the Events and Training page to review training dates and secure your spot.

A delegation of procurement authority, or DPA, is a written authority to issue an order under the master contract; it clearly outlines the roles and responsibilities between the GSA OASIS+ contracting officer and the ordering contracting officer. The first requirement to solicit, evaluate, and award task orders under OASIS+ is that the Contracting Officer, or CO, must obtain an OASIS+ DPA to become a “delegated” OCO.

When is a DPA required?

You need an OASIS+ DPA:

If you are a CO who plans to solicit, evaluate, award, and modify task orders against the OASIS+ contracts.

Obtaining an OASIS+ DPA is the first requirement a CO must meet to solicit, evaluate, award, and modify task orders under OASIS+. A CO must obtain an OASIS+ DPA from an OASIS+ CO to become a “delegated” OCO. The task order OCO is the sole and exclusive government official with authority to solicit, evaluate, award, administer, and/or modify a task order under the master contract.

An OASIS+ DPA is not required to conduct market research into the OASIS+ program or to use eBuy to conduct market research, which includes issuing RFIs. OASIS+ DPA training is encouraged for any staff (Program Manager, Contract Specialist, Finance, Interns, etc.) interested in and/or administering an OASIS+ requirement. The training is required for any staff to post a solicitation in eBuy; however, only a warranted CO may obtain the OASIS+ DPA. 

The dates of upcoming OASIS+ DPA training sessions are available on the OASIS+ Events and Training page.

NOTE: Contract Specialists and other acquisition personnel are highly encouraged to take the OASIS+ DPA training course.

To obtain an OASIS+ DPA, a CO must:

  1. Be a warranted CO as defined in FAR 2.101 definitions; and
  2. Attend OASIS+ DPA training; and
  3. Formally apply for the OASIS+ DPA via the DPA Request form.

You do not need a DPA:

To conduct market research into the OASIS+ program or to use the task order solicitation system (eBuy) to conduct market research, which includes issuing RFIs.

If you are an OASIS+ Contract Section G.2.2.1 Ordering Contracting Officer, Contractor employee*.

*In accordance with OASIS+ Contract Section G.2.2.1 Ordering Contracting Officer, Contractor employees are authorized under FAR subpart 51.1 Contractor Use of Government Supply Sources to use OASIS+ and are considered OCOs and are not required to obtain a DPA as their authority is granted to them by a Federal Government CO administering an applicable contract (e.g., a Federally Funded Research and Development Center or FFRDC). In order to authorize a Contractor employee under FAR subpart 51.1 to use OASIS+, the Federal Government CO granting authority shall first obtain an OASIS+ DPA.

Follow these steps to obtain your OASIS+ DPA?

To obtain an OASIS+ DPA, a warranted CO (appointed according to FAR 1.603) or an official authorized to obligate funds for the agency must:

Requestors must provide a .gov or .mil email address. If you do not have a .gov or .mil work email address, please contact the OASIS+ Program Team at OASISPLUSDPA@gsa.gov.

  1. Warranted Contracting Officer

    • You must be a warranted CO as defined in FAR 2.101 definitions.
  2. Attend an OASIS+ DPA Training

    • Register for web-based training - Once registration is approved by the OASIS+ staff, you will receive an email confirmation and Zoom access for the upcoming class, or
    • Request in-person training - To request live training for 25 or more people fill out the following form, or
    • Online DAU training class (Class FAC 154) - OASIS DPA training is now available on the Defense Acquisition University, or DAU, 24 hours a day 7 days a week, or
    • Click here to register for an upcoming OASIS+ DPA training session.
  3. Review the following OASIS+ materials

    • OASIS+ Delegation of Procurement Authority Memorandum of Agreement (MOA) [PDF - 81 KB]
    • OASIS+ Buyers Guide
  4. Submit documentation

    • Please send your certificate of completion and a copy of your warrant to OASISPLUSDPA@gsa.gov.
  5. Request OASIS+ DPA

    • Use the form to request an OASIS+ DPA letter

You have an OASIS+ DPA, now what?

Once a CO receives an OASIS+ DPA, the individual is officially identified as an OCO. An OCO has the authority to award, administer, and modify task orders against the OASIS+ contracts. COs that do not have OASIS+ DPAs may not award task orders under OASIS+.

OASIS+ DPAs are issued to individuals; not to agencies. OASIS+ DPAs may be revoked at the discretion of the OASIS+ Contracting Officer(s). There is no limit on OASIS+ DPAs issued per agency, and individuals may repeat OASIS+ DPA training as often as they prefer.

Support developing solicitations

We’re here to help you properly navigate the OASIS+ contract vehicle by providing complimentary scope reviews of your requirement. Below are additional resources to aid in that process:

Additional terms and conditions

Traveler reimbursement is based on the location of the work activities and not the accommodations, unless lodging is not available at the work activity, then the agency may authorize the rate where lodging is obtained.

Unless otherwise specified, the per diem locality is defined as "all locations within, or entirely surrounded by, the corporate limits of the key city, including independent entities located within those boundaries."

Per diem localities with county definitions shall include"all locations within, or entirely surrounded by, the corporate limits of the key city as well as the boundaries of the listed counties, including independent entities located within the boundaries of the key city and the listed counties (unless otherwise listed separately)."

When a military installation or Government - related facility(whether or not specifically named) is located partially within more than one city or county boundary, the applicable per diem rate for the entire installation or facility is the higher of the rates which apply to the cities and / or counties, even though part(s) of such activities may be located outside the defined per diem locality.
