Reinstallation of SPX Marley NC cooling towers on the roof of business center

TDIndustries was contracted to change out a 31 year old mechanical system at Thanksgiving Tower in downtown Dallas. A helicopter lift was required to remove and replace the cooling towers and dead pipe on the rooftop. The entire lift was completed in 12 hours.
TD removed 8 old cooling towers, the heaviest weighing 13 000lbs, and all the dead pipe from the old system. 8 new cooling towers were lifted to the rooftop to replace the old ones.
2 helicopters were used to complete 67 lifts. Over 70 people were involved in the lift.
