NSI was contracted to build a 225 foot cofferdam using 25 foot sheet for the new intake. The 5 sided structure was constructed with a single level of steel beams. The contractor found the steel sheet wall was so well fitted that only minimal water pumping was needed to keep the excavation clear and dry for installation.
