John Turner Consulting Inc.

John Turner Consulting Inc., a geotechnical consulting and materials testing firm headquartered in Portsmouth, New Hampshire, delivers soil testing, asphalt density analysis, geophysical surveying, and related environmental and construction materials inspection services to federal agencies as a prime contractor (75% of awards) and subcontractor. The vendor competes full-and-open across a small but recurring customer base; no set-aside designations recur across the prime footprint, though one individual Army Corps award carried a total small-business set-aside.

The company operates as a parent entity with one named subsidiary, Fessenden Geo-Technical LLC, which is separately chartered as a limited liability company. Award history dates to at least 2014 and spans testing laboratories and services (11 awards), engineering services (3 awards), and construction-support inspection work (1 award each under commercial building construction and miscellaneous support services categories). Primary PSC codes reflect the materials-testing core: Other Environmental Services (6 awards), Quality Control–Construction and Building Materials (3 awards), and construction and miscellaneous inspection (3 awards combined).

Customer concentration is extreme. The Department of the Army Corps of Engineers Engineering District New England accounts for 10 of 16 total awards and $346 thousand of the $441 thousand combined potential value (78% of volume and 78% of dollars). The Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 1 holds 5 awards valued at $91 thousand, and the Department of Agriculture Forest Service R9-Eastern Region holds 1 award for $5 thousand, collectively accounting for 100% of recent activity. Concrete recent prime work includes a $2,250 firm fixed-price purchase order from Army Corps of Engineers New England District on May 17, 2024, for asphalt density testing at Vandenberg Gate in Concord, Massachusetts (completed May 31, 2024), and a $1,287.88 purchase order from the Defense Counterintelligence and Security Agency's New England District on May 14, 2026, for test pit sample analysis in Plymouth, Massachusetts. John Turner Consulting also holds a single-award blanket purchase agreement with Army Corps of Engineers New England District for material testing services, ceiling $250 thousand, awarded September 15, 2022, and running through September 14, 2025; under this BPA, a $1,155 total small-business set-aside call order was issued August 8, 2023, for soil testing in Lincoln, Massachusetts.

The vendor operates under two IDIQ vehicles: the USACE New England A–E MATOC (General Engineering & Design) IDIQ, against which 3 task orders have been placed, and two smaller blanket purchase agreements (combined 2 task orders, $1 thousand potential value). Activity has remained sparse but consistent — one to three awards per fiscal year over the past five years. The most recent award is from May 2026, and combined dollars obligated ($491 thousand) exceed combined potential value ($441 thousand), indicating prior years' performance at or above ceiling across multiple orders.

In subcontractor capacity, John Turner Consulting supplies geophysical surveying and mapping services to Jacobs Engineering Group Inc. on the Human Engineering Laboratory Design project at Natick Soldiers Systems Center in Natick, Massachusetts, with three sub awards dated December 30, 2025, October 15, 2025, and March 19, 2025. The vendor also served as an environmental manager subcontractor to the Gilbane-Exyte joint venture on construction of the Advanced Compound Semiconductor Laboratory/Microsystem Integration Facility at Hanscom Air Force Base in Bedford, Massachusetts (sub award July 20, 2022). Service Contract Inventory data shows minimal activity — one FY2022 SCI record as a named subcontractor with zero prime records above the $150,000 reporting threshold — confirming that federal services revenues are narrow-margin purchase-order and small-BPA work rather than significant staffed-labor contracts. The vendor's footprint is regionally concentrated (all work performed in Massachusetts and New Hampshire) and customer-concentrated (one federal customer anchoring three-quarters of volume and value), presenting recompete risk as existing Army Corps and Veterans Affairs task orders expire but limited growth runway beyond the New England market.
