DESIGN & PERMITTING

Our professional and technical services relative to dam design and construction include four primary areas:

  • New dam investigation and design
  • Safety inspections of existing dams
  • Remedial dam and spillway repair investigations and design
  • Construction administration and CQA

WATER RESOURCES AND CIVIL ENGINEERING

GEA has extensive professional experience in water resources including dam planning and permitting, dam removals, hydrology and hydraulics modeling, stream restoration and enhancements, Best Management Practice (BMP) design and operations, watershed management planning, erosion and sediment control design, flow measurement, interpretation of water quality data, and water quality modeling.

GEA personnel have completed numerous designs related to dams, dam removal, breach analysis, river analysis, watershed studies, emergency action planning, and natural channel restorations.

SUBSURFACE INVESTIGATION AND ANALYSIS

GEA routinely conducts subsurface investigations to obtain the information needed for the design of dam foundations, earthen structures, cut slopes, and embankments. These investigations typically involve the installation of subsurface borings and materials testing. Information obtained from field investigations is used to develop and support the analyses performed during the remainder of the design process, including determination of bearing capacity and settlement, slope stability, internal drainage measures, dynamic loading and response, lateral loading, and uplift restraint. GEA also has considerable experience in the evaluation and selection of ground improvement techniques, if needed, to accommodate less than favorable site conditions.
