Lee Hall Reservoir Spill Way Repair

This project required Crofton to replace an existing spill way valve which was 15’ below the existing lake level. Crofton installed a 100’ x 70’ reinforced steel sheet pile cofferdam and dewatered the cofferdam. Once dewatered, spoils from around the existing valve were removed, the existing valve was dismantled, and a new manhole and valve was installed. The cofferdam was then backfilled with 3 different layers of fill material which totaled 4000 cys of fill.
