September 12 marked the official start-up of One South Broad’s new cooling tower, installed in late June at the former PNB Building by owner Broad One LP. Flipping the switch to “on” was the easy part. The hard part was lifting structural steel, piping and four 7,000-lb. cooling tower sections into position atop the 25-story building at Broad and Chestnut Streets from a staging area near 15th and JFK Boulevard.
According to Dave McFarland of PSP Management LP, the property manager, “The operation was a success due to great teamwork between Herb Schwagerl , our chief engineer, CHI Aviation, which supplied and piloted the helicopter, Thackray Crane Rental, Limbach Construction, Jupiter Inc. for structural steel erection, O’Donnell & Naccarato Structural Engineers, and Bruce E. Brooks & Associates, the MEP engineer. It was exciting to watch. All told, it took about six hours and around a dozen separate ‘picks’ of grabbing the piece of equipment and flying it to the roof for placement.”
Representing BBA during the process were Chuck Argue and Nick Calcagni, who shot a video which conveys the difficulty of placing a cooling tower on the roof of a high-rise, downtown office building, and the precision required of the helicopter pilot and construction team to do so.
