Buy products and services outside a contractor’s MAS contract

Order-level materials, or OLMs, are supplies or services acquired in direct support of an individual task or delivery order placed against a MAS contract or BPA, when the supplies or services are unknown at the time of the MAS contract or BPA award. The prices of OLMs are not established in the MAS contract or BPA. OLMs include direct materials, subcontracts for supplies and incidental services for which there is not a labor category specified in the MAS contract, other direct costs, and indirect costs. MAS includes a dedicated OLM SIN which may only be used in direct support of another awarded SIN.

  • Review which MAS subcategories may have authorized OLMs.
  • Learn how to place orders for OLMs, including sample language.
  • Learn how to administer MAS contracts with OLMs.
  • Review OLM best practices for contractors.

How OLMs benefit you

  • OLMs provide a total solution to meet your requirements.
  • They reduce your agency’s procurement and administrative costs.
  • There is increased competition, which saves you money.
  • All MAS terms and conditions apply, so you know your buys are compliant with FAR and other regulatory guidelines, such as Trade Agreements Act or environmental attributes clauses.
  • It’s cumbersome for ordering activities to add non-MAS (open-market) supplies or services to a MAS order under FAR 8.402(f) procedures.
  • OLMs increase your flexibility to purchase supplies or services necessary to support MAS orders.
  • They reduce administrative costs related to contract duplication.
  • Agencies can better use the MAS program for total solutions.
  • OLMs enhance competition under the MAS program

Other direct costs

In most scenarios, the new OLM authority is the most streamlined method of acquiring ODCs. You can acquire ODCs through:

  • OLM authority
  • Ancillary SINs
  • Contractor team arrangements
  • Open-market procedures using FAR 8.402(f)

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.
