About GZA GeoEnvironmental
GZA GeoEnvironmental (legal name GZA GeoEnvironmental, Inc.) is a national provider of geotechnical and environmental engineering services headquartered at 249 Vanderbilt Avenue, Norwood, Massachusetts. The firm was founded in 1964 by Donald Goldberg and William Zoino, two MIT-trained engineers, originally operating as Goldberg Zoino and Associates (the “A” in GZA stands for “Associates”). The first office was in Cambridge, MA, before relocating to Norwood.
GZA operates with ~800+ professionals across 32 offices and has completed over 100,000 projects nationally and internationally since its founding. The firm publicly publishes a “One Company” philosophy emphasizing knowledge transfer across offices. GZA serves agriculture, buildings, energy, government, industrial, institutional, legal, transportation, and water sectors.
GZA appears in ENR’s 2025 and 2026 Top 500 Design Firms lists (currently around rank #135) and was recognized in 2025 with the ENR Best Highway/Bridge Award for the Madawaska–Edmundston International Bridge Replacement. PitchBook lists GZA as formerly PE-backed and now in “acquired/merged” status — buyers contracting with GZA should confirm current ownership and corporate structure directly with the firm.

Where GZA Stands Out: Geotechnical + Environmental Combined
GZA’s origin as a geotechnical engineering firm (founded in 1964 by Donald Goldberg and William Zoino, two MIT-trained engineers) shapes its current positioning. While many environmental consulting firms have added geotech as a sideline, GZA grew up the other way around — geotech is the foundation, and environmental work integrates with that core competency.
For CRE buyers, this matters when:
- The site requires both Phase 1 ESA and geotechnical investigation for a single deal — bundled scope, one PM, one mobilization
- The property is on fill, soft soil, or has settlement history — geotech depth informs the environmental work
- A dam, levee, waterfront, or coastal property is involved — GZA has specialty practices for all of these
- Brownfield redevelopment requires both geotechnical foundation design and environmental remediation oversight
Full Service Stack
- Phase I ESA (ASTM E1527-21 / AAI-compliant)
- Phase II ESA — soil, groundwater, soil-vapor investigation
- Geotechnical Engineering — foundation, slope stability, soil-structure interaction (the firm’s heritage practice)
- Brownfield Redevelopment — state VCP, EPA Brownfields Program
- Superfund / CERCLA Site Work — investigation, remediation, long-term monitoring
- Water Resources — surface water, groundwater, hydrology
- Ecological Services — wetlands, endangered species, ecological risk assessment
- Dams and Levees — design, inspection, rehabilitation
- Waterfront and Coastal Engineering — port, marine, coastal-resilience
- Construction Management — for remediation and infrastructure projects
GZA’s staff includes ASTM-certified instructors — meaning the firm employs professionals who teach the very standards that drive Phase 1 and Phase 2 ESA work.
Sectors Served
GZA’s nine industry sectors:
- Agriculture

- Energy
- Government
- Industrial
- Institutional
- Legal (litigation support)
- Transportation
- Water
Service Area
GZA operates from 32 offices nationwide and has completed 100,000+ projects over six decades. The firm’s “One Company” philosophy emphasizes knowledge transfer across offices, meaning a buyer engaging GZA in any market gets access to the firm’s full institutional knowledge rather than just a local team. Strong Northeast density (the firm’s heritage market), with significant presence in the mid-Atlantic, Southeast, and select West Coast markets.
Best For
- Combined Phase 1 ESA + geotechnical engagements — single firm, integrated scope (rare differentiator)
- Waterfront, coastal, and resilience-driven CRE deals — dedicated practices
- Brownfield and Superfund redevelopment — established remediation capability
- Dam, levee, or floodplain-adjacent property acquisitions — niche expertise
- Northeast and mid-Atlantic CRE — heritage market depth
- Litigation-adjacent environmental matters — Legal sector practice
- Buyers who value technical / academic rigor — MIT-trained founders, ASTM-instructor staff
- Institutional and government clients with multi-discipline scope
