Mohegan Sun Arena
In addition to doing the structural excavation for the arena's original construction, J&H Excavating was recently involved in the removal and replacement of the building's ice floor. This work involved cutting and removing the existing concrete floor. After the floor was removed, new sub-base had to be installed for the new slab and mechanical piping. This newly installed sub-base was placed with a dozer
using automatic grade control from a robotic total station. This allowed the material to be placed to a tolerance not realistically achievable by conventional methods.
