HMB Implosion Vibration Consulting
To ensure that expensive and sensitive equipment in the MD Anderson Cancer Center Ambulatory Care Building and Cancer Prevention Building were not affected, vibration levels in the buildings were evaluated during the scheduled implosion of the adjacent 18-story Houston Main Building (HMB). High-sensitivity accelerometers and geophones were used prior to implosion to establish baseline readings during normal operations. Vibration levels were measured during the implosion and subsequent debris removal and results revealed levels only marginally exceeded the operating limits for select computer equipment for a fraction of a second. All measured data fell below the thresholds for structural damage as reported by the Office for Surface Mining and Reclamation.
