About this opportunity
The Army Contracting Command at Aberdeen Proving Ground intends to increase the ceiling on contract W56ZTN23D0002 under the Basic Environmental Support Services IV (BESS IV) 8(a) Multiple Award Task Order Contract on a limited-sources basis, restricting competition to a pre-qualified pool of four 8(a) contractors currently holding BESS IV positions.
The justification cites 10 U.S.C. 3204(a)(1), as implemented by RFO 6.103-1, which permits limited-source contracting when required services are available only from a limited number of responsible sources and no other service type will satisfy agency requirements. The four incumbent contractors are the only sources capable of satisfying the requirement without causing a catastrophic lapse in mandatory environmental compliance services at Aberdeen Proving Ground. Each has been deemed technically acceptable, possesses active APG security badging, maintains approved Health and Safety Plans, and is currently mobilized on-site. In accordance with DFARS PGI 206.104-71, a Sources Sought Notice was posted to SAM.gov on 1 July 2026; no responses were received from vendors outside the current MATOC pool capable of meeting immediate mobilization and badging requirements. The original contract was awarded on 15 March 2023. Place of performance is Aberdeen Proving Ground. NAICS 541620 (Environmental Consulting Services); PSC F999 (Other Environmental Services).

The Basic Environmental Support Services IV (BESS IV) is an 8(a) Multiple Award Task Order Contract (MATOC). Under 10 U.S.C. § 3204(a)(1), as implemented by RFO 6.103-1, agencies may contract without providing for full and open competition when the required services are available from only one responsible source, or for the DoD, from only a limited number of responsible sources, and no other type of services will satisfy agency requirements.This ceiling increase restricts competition to the limited number of responsible sources currently holding BESS IV contracts (a pre-qualified pool of four 8(a) contractors). Because these four contractors have already been deemed technically acceptable, possess active APG security badging, have approved Health and Safety Plans, and are currently mobilized on-site, they are the only sources capable of satisfying the agency's requirements without causing a catastrophic lapse in mandatory environmental compliance services.In accordance with DFARS PGI 206.104-71, a Sources Sought Notice/RFI was posted to SAM.gov on 01 July 2026. No responses were received from vendors outside the current MATOC pool capable of meeting the immediate mobilization and badging requirements.
