GZA GeoEnvironmental

GZA GeoEnvironmental is a multi-disciplinary consulting firm providing geotechnical, environmental, ecological, water, and construction management services. It was founded in 1964 by two geotechnical engineers and says it has completed over 100,000 projects nationally and internationally.

For buildings and real estate, the practice covers environmental site investigation, site and civil engineering, geotechnical engineering, geostructural and construction engineering, landscape architecture, environmental planning, EHS regulatory compliance, sustainability services, and natural hazard risk management, climate adaptation, and resilience. A separate building and property services group performs environmental and property condition assessments ahead of renovations, demolitions, and transactions, covering asbestos, PCBs, heavy metals, radon, mould, bacteria, universal wastes, and containerized chemicals, then designs and monitors hazardous building material removal and tracks findings in an environmental management system database. For one client alone the firm reports inspections and assessments at over 1,500 owned facilities.

The firm is employee-owned and describes a private ownership structure that gives staff ownership opportunities. More than 800 professionals work from 34 offices across the United States, and the firm operates on a One Company basis so that any client can draw on staff outside their project's region. It recently purchased the assets of Siefert Associates, whose employees joined GZA.
