Case Atlantic is installing 400 bored piles for the replacement Cooper River Bridge in South Carolina. The bridge, which will have the largest cable stay span in North America, connects the Charleston peninsula with Mount Pleasant. Work is being carried out for South Carolina's Department of Transportation.
Both temporary and permanent casings are being installed in the river, on a trestle over a marsh and on both banks. River piers are designed to resist varying degrees of ship impact as well as seismic activity. The piles are 3m in diameter and go to depths of 72m. Each will require up to 573m 3 of concrete.
