Recently the Children's Hospital in Detroit experienced a unique construction occurrence - quiet demolition. This interesting method will have further applications for contractors working with tight restrictions on demolition.
Proposed renovations called for removing a portion of the original 6-inch-thick roof slab and 12-inch-thick supporting walls. Primary concerns were noise, dust, and vibration.
Initially, demolition work was scheduled for 2:00 a.m. to 10:00 a.m. - the emergency room's slowest hours. Hospital administrators lifted the restriction on working hours after observing how quietly the crusher operated. Hospital and general contractor Auch personnel were pleased with the demolition's minimal impact on patients and hospital employees working just a few feet away, separated only by a plywood partition.
