JR Merit was the prime contractor for the replacement of a 42-inch flume more than 1,850 feet long located in southwest Idaho. The project included demolition of the existing wooden stave pipeline built in the 1960s and construction of the new, 42-inch spiral-welded flowline that follows the same path as the existing structure with both exposed and buried sections. Aligning both the pipeline and the pipe saddles were critical tasks requiring a precision approach in both design and construction. We hit centerline on 100 percent of our cast-in-place concrete thrust blocks in relation to pipe centerline during final placement and alignment.
