Dams: Design, Construction & Risk Assessment

Overview Related Projects Key People

Dams engineering requires understanding and control of the enormous forces and potential energy of water. From foundation and seismic assessments through to geotechnical, hydrological, hydraulic, mechanical and structural design, projects demand in-depth skills and a coordinated, client-focused approach.

GHD has been involved in dams since the company's birth almost 90 years ago. We have the largest dedicated dams engineering team in Australia and one of the larger teams across the globe. We have more than 100 technical dams people in Australia and growing numbers globally, particularly throughout the Americas, United Kingdom, within Asia and New Zealand.

We recognize our clients' need for solutions that harness in-depth knowledge with imaginative thinking to produce innovative, safe and cost-effective outcomes, working collaboratively to deliver results.

GHD's Dams services include:

Investigations and appraisals
Design of dams and associated infrastructure
Tender and construction phase services
Owner's engineer and review panels
Operational support
Dam safety and risk assessment

We provide these services for the following dam types and appurtenant structures:

Earthfill dams
Earth and rockfill dams
Concrete or membrane-faced rockfill dams
Concrete gravity dams
Roller-compacted concrete dams
Concrete arch and multiple barrel arch dams
Concrete buttress (including diamond-head) dams
Tailings and mining dams
Gated and ungated spillways
Intake and outlet works
Hydromechanical installations

Our integrated dams team is supported by professionals in related fields including geotechnics, geology, hydrogeology, hydrology, river hydraulics, mechanical engineering, environmental sciences, materials technology and structures.

We work closely with clients throughout the entire project life cycle to develop safe, innovative and cost-effective outcomes, maximising benefits for all stakeholders.
