Guerriere & Halnon

What Guerriere & Halnon does

Guerriere & Halnon, Inc. is a privately held civil engineering and land surveying firm founded in February 1972 by Louis L. Guerriere and John D. Halnon, headquartered in Milford, Massachusetts with additional offices in Franklin and Whitinsville. The firm provides professional services across surveying (property line, topographical, wetlands, ALTA/ACSM, construction layout, boundary research), civil engineering (site planning, feasibility studies, drainage and storm water management, subdivision design), sanitary engineering (Title V inspections, percolation tests, septic system design), environmental services (wetlands delineation, Rivers Act compliance, environmental permitting), and consulting (development feasibility, Land Court surveys, title registration). Clients include government agencies, industrial, commercial, and residential developers, private landowners, and design firms across Massachusetts, with multi-state licensing enabling service into Rhode Island, Connecticut, Vermont, New Hampshire, and New York.

Field operations rely on GPS systems (Topcon HiperLite, Leica GPS System 300), robotic total stations (Leica), and electronic data collectors feeding into CAD/CADD systems (Autocad Civil 3D, Land Development Desktop) to produce "field-to-finish" survey plans. The technology stack is conventional precision-instrumentation tooling rather than differentiated proprietary IP; the firm's competitive narrative emphasizes multi-state licensed professional staff, 50+ years of continuous operation, and an outstanding regional reputation in Metrowest Massachusetts.

Revenue is generated through professional services fees structured as project-based custom quotes, with free consultations offered and proposal requests accepted via the company website. There is no disclosed pricing model beyond quote-based engagement, no subscription or recurring SaaS revenue, and no online self-service channel. The firm markets primarily through its website, industry association memberships (Massachusetts Association of Land Surveyors and Civil Engineers, Rhode Island Society of Professional Land Surveyors), and referrals from a documented reference network of named clients and partners. Long-tenured anchor accounts such as Milford Regional Medical Center (across the Meehan Family Pavilion and Emergency Department phases) and national retail brands (Lowe's, CVS) indicate a project-driven but diversified client portfolio. The company is founder-owned and managed with no external private equity or venture capital investment disclosed.
