As an implosion flattened the old City Hall Annex, windows were broken at the Blackstone Building across the street.
Larry Brake, manager of the Blackstone Building, said earlier this month that open sections on the lower floors of the side of the building facing the annex would be covered to prevent dust and debris from being deposited on the building’s parking deck floors.
He said the HVAC system will be sealed to prevent dust from entering the building while the debris cloud settles and all of the air filters will be replaced.
At 8 a.m., explosives were detonated to implode the 15-story, 200,140-square-foot former City Hall Annex at 220 E. Bay St.
Environmental Holdings Group LLC of Mooresville, North Carolina, is the contractor and has been preparing the site since August.
