Prudential Center, Newark, New Jersey - Opened in October 2007, “The Rock”, as its known locally, was constructed on a shallow foundation system following the completion of a comprehensive ground improvement program. Thirteen acres of urban fill was improved by Densification, Inc. using dynamic compaction, which was an aggressive program, given the sensitive urban environmental where the arena was to be constructed. However, the dynamic compaction program was highly successful, even allowing the design team to increase the design allowable bearing pressure from 2 to 3 tons per square foot.
