Dimco Inc.

Dimco Inc., a woman-owned small business based in Vicksburg, Mississippi, supplies architect-engineer surveying and mapping services to the U.S. Army Corps of Engineers as a prime contractor, competing predominantly under Total Small Business set-asides and full-and-open solicitations. The company has been a federal contractor since 2002 and operates exclusively as a prime (100% of recent awards); it does not subcontract work to other federal primes.

Dimco's capability portfolio centers on hydrographic surveying, boundary surveys, gage and discharge monitoring, land surveying, and water resource monitoring in support of Corps water management, flood control, and navigation missions. Representative work includes a $481,954 delivery order for A-E surveying and mapping services (hydrographic, land, and hydrodynamic surveys) awarded by the Army Corps of Engineers' Engineering District Vicksburg on April 10, 2026, under a Total Small Business set-aside; a $346,938 delivery order for architect-engineer surveying and mapping services also from ENDIST Vicksburg on January 29, 2026; and a $202,936 delivery order for discharge surveys, stream gage readings, and gage maintenance from the same district on December 22, 2025. Dimco also performs boundary survey work for the U.S. Fish and Wildlife Service and the Department of Agriculture's Natural Resources Conservation Service, including a $16,569 boundary-line marking and posting contract with Fish and Wildlife Service Region 4 on March 13, 2026.

Customer concentration is extreme: the Army Corps of Engineers accounts for 91% of awards by count and 95% of combined potential value across the vendor's footprint, with the Vicksburg and Memphis district offices (237 awards, $46.7 million combined potential value) and the general Corps organization (143 awards, $17.8 million) anchoring the relationship. The USDA Natural Resources Conservation Service Southeast Region and Fish and Wildlife Service provide secondary volume (22 awards combined, $3.5 million), but the Corps dominates both award-count and dollar rankings.

Dimco holds five active indefinite delivery vehicles: a recently awarded $15 million multiple-award Total Small Business IDV with the Army Corps of Engineers' Engineer Research and Development Center in Vicksburg (September 30, 2025 through September 29, 2030); a $2 million single-award NRCS boundary-survey IDV for 16 counties in southern Mississippi (May 19, 2023 through May 18, 2025); and three legacy Corps IDVs (DACW4202D0002, W912EE06D0003, and W912EQ10D0001 and W912EQ07D0001) carrying 58, 45, and 79 task orders combined with $1.2 million, $1.1 million, and $5.6 million in combined potential value respectively. The top five vehicles account for the majority of recent task order activity.

Activity has declined from 7 awards per year in 2022–2023 to 3–4 awards annually in 2024–2026. Five awards with ultimate completion dates in the next twenty-four months carry combined potential value of $1.9 million, creating moderate recompete exposure. The vendor's $73.7 million combined potential value across 460 recent awards reflects Dimco's long, stable relationship with the Vicksburg-based Corps district rather than portfolio growth; 56% of that potential has been obligated. Dimco competes in Surveying and Mapping Services (NAICS 541370, 183 awards) and Engineering Services (NAICS 541330, 128 awards), with primary PSC coding in Architect and Engineering—General (234 awards) and R&D—Other Research and Development (99 awards).
