Abstract:

All New York City subway repairs take place at a repair shop in Coney Island. The shop's floor was plagued by settlement problems since its construction on a filled swamp in 1927. After years of quick fixes, a major stabilization using mini-piles was instigated in 1984. Cost, $100 million. The mini-piles were successful in stabilizing the floor and did not stop shop operation when installed. These mini-piles were carefully tested during installation. Shop overhaul also included new structures and new equipment, which the mini-piles supported.
