420 Main Street Building
Controlled Demolition, Inc. (CDI), acting as Explosives Subcontractor to Main Demolition Contractor, Renascent, Inc. of Indianapolis, Indiana, performs the preparation for and explosives felling of one (1), 166,300 square foot, 19-story, reinforced concrete office building in Evansville, Indiana on Sunday, November 21, 2021. Renascent, working for General Contractor, Barton Malow, who represented the developer, DOMO Development Company, LLC, performed environmental remediation in the structure before soft stripping the building and gutting out CDI’s specified shot floors. Renascent placed debris to support the two (2) street side basement walls which had not been designed as free-standing retaining walls. They installed cables on multiple floors of the structure, per CDI’s design, so that CDI could pull the tower away from those basement walls to remain and adjacent streets/structures. Vibration monitoring of CDI’s felling of the 18,000-ton structure demonstrated vibration levels well below regulatory guidelines.
