Terradyn Consultants

What Terradyn Consultants does

Terradyn Consultants, LLC. is a privately held civil engineering and land surveying firm headquartered in New Gloucester, Maine, founded in 2005 by Jeffrey Amos, P.E. The firm provides integrated engineering and surveying services to private developers, municipalities, landowners, and design professionals across Southern, Central, Coastal, and Western Maine, operating from three offices in New Gloucester (headquarters), Portland, and Auburn. Its core offerings span six integrated practice areas: civil engineering design (site design, stormwater management, erosion control, road design, municipal infrastructure, and site utilities); land surveying (boundary, topographic, ALTA/NSPS, construction layout, as-built, and elevation certificates); regulatory permitting (MDEP, MDOT, NRPA, U.S. Army Corps of Engineers, and municipal approvals); GIS and geomatic services (site analysis, feasibility studies, terrain visualization, mapping exhibits); land planning and subdivision (master planning, feasibility studies); and construction services (bid documents, cost estimates, construction monitoring, administration, and post-construction inspections).

The business operates as a project-based professional services firm with revenue generated from five streams — engineering design, surveying, regulatory permitting, land planning/subdivision, and construction services — frequently bundled on a single project. Pricing is per-project based on scope and complexity; the firm offers free estimates for survey work and initiates client engagement through website quote requests, phone inquiries, and office visits. Terradyn functions either as lead consultant or as part of multi-disciplinary project teams alongside architects, soil scientists, and landscape architects. Customers span multiple sectors: beverage manufacturing (Maine Beer Co.), retail (Blue Rock Tile & Design Center), restaurants (Ted's Fried Clams), real estate developers (Carry All Corner; The Cottages on Upper Maine), municipal governments (Town of Durham, Town of Cornish), institutional clients (Thornton Academy, with a continuous relationship since 2008), and conservation districts (Cumberland County Soil & Water Conservation District). Marketing is largely referral-driven, supported by a portfolio website and LinkedIn presence; no paid advertising or formal channel partnerships are disclosed.

Terradyn employs 1-10 staff, including licensed Professional Engineers (P.E.) and Professional Land Surveyors (PLS), with senior leadership comprising President and founder Jeffrey Amos, P.E.; Vice President and Partner Michael Tadema-Wielandt, P.E. (Portland office lead, Virginia Tech engineering background, Cape Elizabeth Zoning Board of Appeals member since 2014); and Director of Survey Jimmy Courbron, PLS. The firm has no parent company, no external institutional funding, no patents, no formal partnerships, no app, no API, and no disclosed AI/ML capabilities. Its competitive positioning rests on deep Maine-specific regulatory expertise and established relationships with state and local permitting agencies (MDEP, MDOT, NRPA, U.S. Army Corps of Engineers), supported by long-tenured client relationships across both private and public sectors.
