Thompson Falls - Montana - COP Construction

A-Core Concrete Cutting Specialists of Idaho Falls teamed up with industrial underwater divers to perform core drilling and underwater wire sawing services. The A-Core team was contracted to core drill a 42 inch diameter hole through a wall 10 feet underwater for a fish ladder bypass in Thompson Falls Dam. Also, operators used specialized wire sawing methods to cut a 14 foot tall by 4 foot thick barrier wall on the upstream side of the dam.
