The owner of the unfinished Berkman Plaza II Downtown says that demolition crews will begin removing the upper floors of the structure July 9. Jacksonville Riverfront Revitalization LLC said in a news release July 8 that delivery of a high-reach excavator to the 500 East Bay St. site over the Fourth of July weekend will allow Orlando-based contractor Pece of Mind Environmental Inc. to begin the work. Pece of Mind President Steve Pece said the company has been removing steel and other debris from the 18-story structure and preparing the site for the crane’s arrival since May. “The demolition is expected to take three to four months, weather permitting,” he said in the release.
