- Rueter-Hess Dam and Reservoir
GROUND Engineering provided quality assurance construction observation and materials
testing services for the new construction of the Rueter-Hess Dam and Reservoir in
Parker, Colorado. The Rueter-Hess Dam has 22,000 acre-feet of active water storage
and is classified as a Large, Class I (High Hazard) dam based on its size and relative
risk to population. The 7,700 LF long crest has a maximum height of 195 feet from
the existing streambed and required approximately 12.5 million cubic yards of material
placement. All laboratory testing was conducted at the on-site materials laboratory,
provided by GROUND. Additional testing provided by GROUND includes ultrasonic and
radiographic weld testing for steel piping.
