IFS lifted more than 42 tons of equipment by air crane helicopter to replace the HVAC rooftop units at Mid Rivers Mall. The four-hour project involved 16 helicopter lifts to remove four existing HVAC units (two units had to be cut into two pieces due to their weight); four curb adaptors for placement of the units; and replace with four new HVAC units.
The new units provide more than 280 tons of refrigeration capacity, increase efficiency and improve fresh air ventilation for better comfort and a healthier indoor environment for the thousands who visit the popular mall.
To ensure complete safety, an area within 200’ of the helicopter lift was cleared of any materials that could become flying debris hazards in the 70 MPH downwash created by the helicopter rotors. Entrances to the mall were locked and only workers essential to the project were allowed on-site.
The team monitored weather conditions during the week leading up to the helicopter lift, since strong, sustained winds over 35 mph or lightening would delay or cancel the project. Despite rain, threatening skies and up to 25 mph winds, the project was completed on time with no injuries or incidents.
