The floor tolerances for this Merck Pharmaceutical manufacturing facility were specified at Ff60 Fl40. The Donley’s Concrete Group finishing team exceeded the specified slab tolerance and ended up with Ff 78 Fl 47.
The structure houses the main switchgear for the entire Merck facility. The high tolerance floors were installed to allow massive transformers to be replaced with an air pallet system that utilizes a cushion of air to lift and float the transformers across the floor to the desired location.
