Schuepbach Builders’ fish passage and diversion structure project for East Fork Irrigation District has been nominated with 20 other companies across the country for the 2013 Crews That Rock Award.
Crews That Rock will be presented at the World of Concrete trade show in Las Vegas in January.
The deadline for online voting is Dec. 13. To vote, go to http://bit.ly/18NJLM3.
The project consisted of constructing an earth coffer dam across the Hood River, diverting the entire river through the existing headworks into the irrigation canal. Two hundred yards down the canal, there was a temporary structure of ultra blocks and slide gates installed to control the canal flow with an overflow bypass returning the remaining water to the Hood River.
Randy Baker of Schuepbach described the project:
“This is the third year in a row Schuepbach Builders has landed an in-river project with tight timelines to complete the project. We had 77 calendar days for the in-water permit. Fifteen days into the project, the Confederated Tribes of Warm Springs and the Oregon Department of Fish and Wildlife wanted an accelerated schedule. We negotiated cutting 10 days off of the original permit, giving us 67 days total to complete.
“It was very important to keep the flow of water to the orchardists in the valley, as it is critical time for the fruit growth. We then began construction on the 146 linear-foot by-8-foot fish ladder with 10 interior weir walls for creating back eddy for fish travel.
“Followed by a 44-foot wing wall on the opposing side of the river and a very complicated footing 50-foot by 10-foot by 4-foot crossing the river, this would be the base for an air bladder controlled Obermeyer dam.
“The dam was installed to control the water into the irrigation canal and the fish ladder.
“We finished up with a four-bay headworks structure and jib crane, and then removed the old headworks and the coffer dam without ever leaving the orchardists high and dry.
“We used 1,113 man hours, 88,000 pounds of rebar, 445 yards of concrete and Doka Frami formwork to complete in 52 working days. During the course of construction, we even had a surprise visit from U.S. Rep. Greg Walden.”
