Project Details: Installed a 20’x20′ cofferdam for a 25′ excavation adjacent to the Wisconsin River. This cofferdam was extensively braced with HP12x74# wales and gussets. We used a sectional barge to support a Mainitowoc 3000W crane with a V-17 MKT vibratory hammer to drive the PZ 27 steel sheet piles.
