Dam Design
& Build


Dam operators and owners have enough to worry about. We offer a multifaceted approach to dam design and construction, complete with insight from previous dam operators. This means you can maintain focus on daily operations and safety while we take care of the details. Whether you are looking to repair/rehabilitate a spillway or design a new dam, our focus on water resources provides comprehensive solutions. We also install and repair supporting mechanical and electrical components to enable flexibility, enhance safety, and lower total cost of ownership. Every detail matters.

scopes of work

We've got you covered.

  • Concrete gravity and arch dams hundreds of feet high and small earthen or rock-filled diversion structures, levees, or dikes
  • Dams for hydropower and pumped storage, irrigation, recreation, or flood control
  • Strategy development for compliance with updated codes and standards
  • Non-destructive testing and evaluation of concrete and steel infrastructure
  • Dam raises for increased power, storage capacity, or flood protection
  • Rehabilitation/repair of spillways, tailrace, piers, forebay, etc.
  • Fire life safety (suppression, alarms and mass notification, smoke detection and controls, HVAC, and access control)
  • Dam safety services
  • FERC coordination
  • Dam removal
  • Design and construction of all heavy civil/concrete work and installation of steel components
  • Cofferdams and dewatering
  • Design and construction of ancillary structures:
  • ~~Gate rehabilitation and replacements (radial, sector, and vertical lift gates) including gate inspections in compliance with FERC Chapter 14 Appendix L
  • ~~Bulkheads and stoplogs
  • ~~Intakes and Low-Level Outlets (LLO)
  • ~~Mechanical systems installation and upgrades (e.g., cranes, hoists, valves, hydraulic power systems, piping systems, and seals)
  • ~~Fish passage options including trap and haul
  • ~~Sediment and debris management (e.g., debris booms and trash rakes/racks)
  • ~~Electrical (switchboards, motor control centers, ACDC power distribution, remot monitoring/SCADA, and emergency/backup generators)
  • Hydrology and hydraulics including Probable Maximum Flood (PMF), inflow design flood, flood routing, dam break analysis and inundation mapping, CFD modeling, scour analysis, Total Dissolved Gas (TDG) abatement, outlet/spillway capacity, stage discharge-curves, energy dissipation performance, and hydraulic transient and surge analysis
  • Condition assessments including rope access methods
  • Geotechnical and geologic investigations including rock and soil mechanics, stability analysis, seepage and spillway scour analysis, reservoir rim evaluations (slopes and landslide hazards), and filter evaluations
  • Gravity, pseudo-dynamic, and dynamic analysis procedures 2-D and 3-D finite element modeling
  • Structural stability analysis and modeling including Finite Element Analysis (FEA/FEM) and sliding, overturning, and cross-canyon analyses
  • Seismic assessments including liquefaction potential, Deterministic Site Hazard Analyses (DSHA), and Probabilistic Site Hazard Analyses (PSHA) which include response spectrum and time history techniques
