Johnson-Mcadams Surveying & Mapping LLC

Johnson-Mcadams Surveying & Mapping LLC, an SBA-certified HUBZone small business based in Greenwood, Mississippi, delivers surveying, mapping, and geospatial services to the U.S. Army Corps of Engineers as a prime contractor, with 678 awards across a 26-year contract history and $177 million in combined potential value. The company operates exclusively as a prime contractor; all 678 awards in the source data are prime contracts or IDIQs with no subcontract work, positioning Johnson-Mcadams as a specialized provider rather than a teaming partner or subordinate performer.

Johnson-Mcadams' customer base is almost entirely concentrated within the Army Corps of Engineers and its districts. The top five customer entities account for 98% of awards: the Corps' Memphis Engineering District (215 awards, $27.2 million), Vicksburg Engineering District (206 awards, $39.2 million), the parent Army Corps of Engineers account (168 awards, $64.7 million), the Department of the Army (3 awards, $25.2 million), and the New Orleans Engineering District (72 awards, $14.6 million). When aggregated under parent agency, the Department of the Army Corps of Engineers dominates 97% of combined potential value. The company's capability portfolio centers on topographic surveys, hydrographic surveys, boundary surveys, construction layout surveys, cross-sectional surveys, dam and levee inspection and evaluation, seepage remediation assessment, GIS mapping, and aerial surveying in support of the Corps' flood control, navigation, water resources management, and infrastructure missions across Louisiana, Mississippi, Arkansas, and Missouri.

Work is grounded in two large IDIQ vehicles. Johnson-Mcadams holds a $20 million multiple-award IDC (W912EE25D0006) awarded December 30, 2024, effective through January 31, 2030, covering surveying and mapping services primarily for the Memphis District. The company also holds a $25 million multiple-award IDC effective through November 18, 2025 (both set-aside Total Small Business), which has fed 88 task orders under W912P810D0052 alone. Across its IDIQ portfolio, individual delivery orders have ranged from approximately $44,000 to $2.778 million, with firm fixed-price task orders the norm. The vendor's top five parent vehicles account for 319 cumulative task orders and $22.3 million in combined potential value, spanning contracts focused on architectural and engineering surveying (W912P810D0052: 88 orders; W912EQ16D0005: 69 orders; W912P820D0003: 61 orders; W912EE09D0001: 56 orders; W912EE06D0018: 46 orders).

Recent awards underscore levee-and-dam-centric work. Representative 2025–2026 delivery orders include a $135,039.60 March 2026 Mississippi River levee quality-assurance construction survey (Vicksburg District, Total Small Business set-aside, completion December 2027); a $224,261.50 February 2026 Yazoo Backwater Levees survey (Vicksburg, Total Small Business, November 2026); a $241,498.10 January 2026 general surveying services call (Vicksburg, Total Small Business, December 2026); and a $384,000 August 2025 Arkabutla Dam outlet structure survey (Vicksburg, December 2025 IDC). Many task orders carry no additional set-aside designation beyond the vendor's HUBZone status, competing on open basis; a subset are formally designated Total Small Business set-asides.

Activity has been steady across the five-year snapshot: 21 awards in 2022, 26 in 2023, 18 in 2024, 22 in 2025, and 4 recorded through March 2026. Only six awards face ultimate completion within the next twenty-four months (combined potential value $1.2 million), indicating limited near-term recompete exposure at the delivery-order level; the larger strategic exposure lies in renewal of the $20 million and $25 million IDIQs. By NAICS, 472 awards fall under Surveying and Mapping (except Geophysical) Services, with 197 under Engineering Services; by PSC code, the bulk align with Architect and Engineering–General work (351 awards) or Architect and Engineering–General Other (313 awards). Johnson-Mcadams operates as a geographically concentrated, single-agency vendor with deep, multi-decade relationship roots at the Memphis, Vicksburg, and New Orleans districts, competing predominantly on technical excellence and HUBZone preference rather than across competitive vehicle portfolios.
