Fall Creek Reservoir and Fish Ladder
Lowell, OR, United States

The U.S. Army Corps of Engineers commissioned RCSI to upgrade the existing Fall Creek Reservoir fish facility to comply with current environmental criteria as well as build a new fish lab to transport native salmon and endangered species. The full project included a new fish ladder, pre-sort structure, fish crowder, transportation flumes, anesthetic tank, recovery tank, false weir, brail assembly, headbox dewatering flume, and post-sort structure.

The approximately two-year project came with many complexities, including the restriction of a tower crane, which resulted in the contractor selecting DUO handset formwork, ultimately reducing equipment costs. Originally RSCI bid to achieve a production rate of 0.16 man-hours per square foot with the DUO system. But, when workers began using the lightweight, durable, and intuitive formwork they were able to achieve 0.09 man-hours per square foot, cutting the production rate in almost half and providing additional cost savings to RSCI

DUO handset formwork system was primarily used to form the steps of the fishway.
