Colorado Dam Safe Passage Project (Bend Whitewater Park)
Start Date: April 2014
End Date: September 2015
Hamilton was the CM/GC for the Colorado Dam Safe Passage project which removed portions of an existing dam and the existing pedestrian bridge to allow inner-tubers and kayakers safe access through the Colorado Avenue corridor of the Deschutes River – an urban location. A set of mildly stepped riffles were built on the west side of the channel allowing rafters and tubers to easily traverse the rapids. Down the center of the channel a series of whitewater features were placed to allow kayakers and surfers a course with adjustable standing waves. The whitewater features are adjusted by means of remote controlled pneumatic gates constructed in the riverbed. A habitat channel was built on the east side of the river including multiple water cascades, shallow bedding areas, and back water areas for fish and other aquatic animals. Our team also constructed a weathered-steel wide-flange pedestrian bridge with a concrete cast-in-place deck. Significant redesign to the waterway required that the park district get new USACE permits which required us to re-isolate and drain a portion of the river after initial contract completion. Thanks to the CM/GC project delivery method and the close relationship we established with the owner and engineer we were able to minimize additional costs and schedule impacts.
