Engineering Design

RIZZO prepares conceptual through final designs for dams,  hydroelectric facilities, hydraulic structures, and intake structures. RIZZO also designs  foundations for nuclear, gas, coal fired, and wind power plants; tunnels; shafts;  underground structures;  and other special purpose facilities for the power industry.


We provide structural and foundation engineering services, which includes performing complex structural and geotechnical analyses using state-of-the-art engineering software,  for a wide variety of heavy civil works projects.  Our capabilities extend to all construction materials, and senior-level staff members participate in code committees for organizations such as ASTM, ASCE, and ACI.

RIZZO has particular expertise in dealing with complicated or complex site conditions or structures, , unique materials and performance requirements, intensive regulatory interaction, and/or fast-track schedules.
