GZA supports the latest wave of major construction and compliance projects as decarbonization initiatives continue to spur unprecedented investments in the development of renewable energy.

GZA is a proud leader in geotechnical services for offshore wind developments and land-based infrastructure. GZA provided geotechnical services on four proposed wind farms, including Block Island Wind Farm, the first offshore wind farm in the United States, and we have completed over 300 solar projects.

GZA’s multidisciplinary expertise, proactive approach to regulatory agency engagement, and extensive experience in the power sector, from planning through project close-out, helps our utility clients improve regional reliability, safety, and efficiency.

As utilities make significant investments into the beneficial re-use/ mitigation of legacy generation facilities and manufactured gas plants (MGPs), GZA provides specialized technical knowledge of the facilities, fuels, wastes, by-products, and processes necessary to assess and mitigate the associated physical and environmental hazards. It enables clients to redevelop these high-risk liabilities into commercially productive and community-valued assets. With over 30 years of project experience on hundreds of Manufactured Gas Plant (MGP) sites, GZA is one of the few firms in the United States that can assemble an integrated team of in-house experts to support any aspect of an MGP program.

With valuable stakeholder input, GZA evaluated risk, and where needed, expedited the planning, design, construction, activation, and maintenance of short- and interim-term flood hardening systems at 31 substations located within inland and coastal Special Flood Hazard Areas. This utility’s existing substations are now significantly more resilient to outages from rising sea levels and the increasing trend in storm-related water damages.

Nuclear Facilities

GZA has safely completed over 120 civil-hydrology, geotechnical and environmental projects at 25 U.S. nuclear plants for owners and engineering firms. Our safety-related projects were completed in compliance with a Nuclear Quality Program per 10 CFR 50 Appendix B.

Our engineers and scientists have contributed to the resilience of the most hardened and secure critical infrastructure in the United States. This experience will support the development of innovative designs for new advanced reactor technologies and small modular reactors.

  • Post-Fukushima Flood Hazard Re-evaluations at 23 plants
  • Independent Spent Fuel Installations (ISFSI) Feasibility Studies and Civil-Hydrological and Geotechnical Design
  • Small Modular Reactor (SMR) Feasibility Studies and Design 
  • Groundwater Protection Initiative and Hydrogeological Investigations 
  • Plant Decommissioning and Decontamination Support
Fossil Fuels

We assist clients in their continual efforts to improve the reliability of the nation’s domestic natural gas resources necessary for heating homes and generating electricity during the ongoing retirement of coal- and oil-fired plants. 

Our engineers and scientists provide a wide range of support services for energy companies grappling with the challenges of producing upstream resources, mitigating midstream transmission constraints, and upgrading and expanding downstream storage, refining, and delivery of oil and natural gas.

LNG facilities rely on GZA's full breadth of services from planning through construction and maintenance of major upgrades to improve operational efficiency, meet and exceed regulatory requirements, and increase capacity to serve all customers during future cold weather demands.
