Hedefine Engineering & Design Inc.

Hedefine Engineering & Design Inc., a Subchapter S Corporation based in Dedham, Maine, operates as a prime contractor providing architectural and engineering design services to the National Park Service, with all 67 recent federal awards issued by NPS components in full-and-open procurement without set-aside designation. The firm specializes in Title I, II, and III architect-engineer services for infrastructure improvements, wastewater treatment system design, water system replacements, fire suppression system engineering, road rehabilitation, facility assessments, and structural inspections at national parks and historic sites in the Northeast region.

Hedefine's customer base is concentrated almost entirely within the National Park Service. The Department of the Interior National Park Service Northeast Region accounts for 62 awards with $9.8 million combined potential value, while the National Park Service National Office accounts for 5 awards with $1.5 million combined potential value, covering 100% of recent awards. This concentration reflects Hedefine's position as a specialized vendor for Acadia National Park, which anchors the majority of the firm's work. Representative work includes a $381,716 delivery order for Harden Farms Employee Housing Phase 1C (issued September 2024), a $186,157 contract for Title III infrastructure improvements under ACAD 309000 1C (issued January 2026, ultimate completion July 2027), and a $173,035 delivery order to replace and harden sewer infrastructure at Acadia (issued May 2023). The firm has also delivered smaller-value orders ranging from approximately $2,883 to $105,460 for culvert replacements, boiler rehabilitation, fire suppression design, and facility structural assessments.

Hedefine places nearly all work under a single parent vehicle: Indefinite Delivery Contract 140P4319D0001, the National Park Service Northeast Region's Architectural and Engineering Services IDIQ contract valued up to $7.5 million and set aside for small businesses. This vehicle carries 62 task orders with $3.3 million combined potential value. Award velocity has been uneven — eleven awards in 2022 declining to six in 2023, eight in 2024, and two in 2025 — indicating a flattening or retracting engagement pattern. Five awards carrying combined potential value of $555 thousand reach ultimate completion within the next twenty-four months and face recompete risk.

The Service Contract Inventory dataset captures only limited Hedefine activity due to reporting thresholds: $362 thousand in FY2024 invoiced SCI-reportable revenue across 0.3 FTEs, with government-paid hourly rates at a uniform $119.25/hr. This SCI snapshot is not representative of Hedefine's total federal services revenue, which is dominated by the task-order delivery work under the NPS IDIQ contract. The SCI data shows a 40% average sub-hours share on the reported prime records, with three named subcontractors across SCI-reportable contracts, suggesting Hedefine engages subcontractors for portions of design and engineering delivery on larger orders, though the core work remains prime-delivered. Hedefine operates solely as a prime contractor; the source contains no federal sub-award activity.
