www.concreteproducts.com February 2018 • 71 FEATURE OLDCASTLE PRECAST STEPS TO SPAWNING The $1.4 million Beaver Creek Fish Passage Improvements project was limited to a six-month schedule, owing to water levels and weather restrictions. The remote location, 4,400-ft. elevation and short window presented many challenges: 70 precast concrete sec- tions and a large cast-in-place inlet had to be precisely fabricated, installed and finished to ensure that the complex layout was accurate. The fish passage structure was installed with each precast unit stair stepped upon each other—abiding a radius curve and gradual grade. "All parties involved including the contractor, engineering firm and jobsite representative, worked hard as a team to make sure the project was completed and a great success," notes Oldcastle Precast Nampa's Mike Blackham, P.E. "When you have a group of people will- ing to work together, and all have the same goal in mind, it makes the job a lot easier."
