Scope

  • FERMA was contracted to demolish a 12-story concrete hospital building with an adjacent multi-story structure
  • The new hospital remained fully functional during the old building’s demolition
  • Demolition was conducted in three stages in order to limit disturbance to the new hospital
  • 60,000 SF via floor-by-floor demolition (12 stories) on the East side to safely allow for 220,000 SF of demolition via high-reach methods
  • The third demolition stage consisted of 30,000 SF of the adjacent hospital wing and connecting structure
  • After above grade demolition was complete, the basement was demolished, backfilled, and compacted with clean soil
