Foundation Repair - Helical Piers Installed to Support Second Story Expansion to Mount Vernon, IL Hospital

The hospital had to remain operational during the entire renovation, which posed an issue for access and allowable working space for Woods' installation crew. Helical piles were selected to support the proposed columns given their ability to be installed within the confined space of the existing building using relatively small equipment. The helical piers were installed with a high-flow skid steer, which could be driven through standard double doors and over temporary bridging that spanned excavations within the tight working conditions. For the safety of everyone in the building scrubber attachments were used to mitigate exhaust fumes.
