Because it involved a multifamily residence, the job presented a lot of special challenges with air conditioning units, gas meters and cable boxes located throughout the work site. This required special care.
First, the Cantsink crew had to determine precisely where all of the utility lines ran. It also meant that each hole for the underpinning installation had to be dug by hand to avoid damaging any pipes or cables on the property. In all, the job required 12 underpinning brackets.
As the digging began on the site, the crew also discovered an extra-wide footer 24 inches wide and 12 inches deep that was not attached to the building. The crew used a jack hammer to break through the footing in locations where the underpinning brackets were to be placed, then finished the preparation with a chipping gun to smooth the edges for bracket placement.
