Hydropower

GZA has 55+ years of dam safety engineering on over 1,000 dams combined with in-house hydropower engineering services on 40 kW to 900 MW projects including FERC relicensing, permitting, environmental studies, safety inspections, PFMA Facilitation and EAP Training Exercises. 

MGP

We have assisted over 50 clients, since the early 1980’s, on over 100 former manufactured gas plants (MGPs) located in a variety of geographic and environmental settings, ranging from densely populated urban areas to sites located adjacent to marine and freshwater environments. With more than 30 years of experience assessing and remediating MGP sites around the country, we can fully support your remediation needs for legacy assets and reduce environmental liabilities from your balance sheet. 

Electric & Gas T&D

GZA's exemplary safety record working on over 400 miles of electric transmission and distribution (T&D), over 300 electric substations, and over 100 gas line crossings proves the value of people-based safety. 

Our geotechnical, ecological, and civil engineering services have assisted gas and electric utility companies, and their engineers and contractors evaluated risk; expedite development; design; construct; maintain; and upgrade their assets to meet continually increasing levels of reliability, resilience, and sustainability.

Water Supply

GZA’s hydrologists and water resource engineers are experienced in developing watershed water budgets and reservoir modeling, performing inflow/outflow analyses, estimating seasonal in-stream flows, evaluating the safe yield of water supply reservoirs, providing design repairs for embankment and gravity dams, and all other aspects of waterworks infrastructure permitting, design, construction, startup, operations, evaluations and reports.

Geotechnical/Seismic

GZA has safely completed work at 25 U.S. nuclear power plant sites including geotechnical and civil engineering services in support of the design and construction of 14 Independent Spent Fuel Storage Installations (ISFSIs). GZA provided geotechnical and marine engineering investigation services for the evaluation of cylindrical wedge wire (CWW) screens as cooling water intake structures in support of a facility license renewal process.

Hydrogeological

GZA hydrogeological services at nuclear facilities includes the assessment and characterization of radionuclides to groundwater; subject matter expertise in  relicensing matters under litigation; and support for four Combined Operating License Applications (COLAs.)

Coastal

Our engineers and scientists have contributed to the resilience of the most hardened and secure critical infrastructure in the United States following our completion of post-Fukushima flood studies at 23 Nuclear Power Plants.

LNG

We have supported several extensive Liquified Natural Gas (LNG) modernization and upgrades needed to improve the reliance and reliability of fuel supplies, particularly in geographically resource-constrained regions. Our clients have learned to rely on GZA’s breadth of experience remediating former MGP sites and designing waterfront improvements to complete these projects safely and efficiently. 

Pipeline/HDD

Moving the natural gas to resource-constrained areas requires significant expertise in linear construction and sensitive waterbody and transportation infrastructure crossings. Our engineers and scientists have intimately assisted in evaluating, designing, and installing over 100 high pressure natural gas transmission pipeline crossings and compressor stations. 

Plant Retrofit/Decommissioning

Demolition and redevelopment of our aging fossil plants provide valuable opportunities to interconnecting renewable resources and constructing modern natural gas-fired units to bridge us to a cleaner and more sustainable energy future. Our environmental assessment and remediation professionals can assist in achieving regulatory closure while striving to evaluate remedial alternatives to identify potential cost saving strategies and efficiencies.
