Selected Ground Freezing Projects:
- Russia Wharf Tunnel: Boston, MA
Designed and supervised installation of a ground freezing system under historic buildings in downtown Boston to preserve the ground stabilization during tunnel construction.
- Verglas Crown Pillar Excavation: Rouyn-Noranda, Quebec, Canada
Designed and supervised the largest structural excavation using ground freezing as a method of ground stabilization. The completed excavation had a diameter of 220 feet and extended 125 feet deep into the crown pillar of an existing zinc and nickel mine.
- Aquarius Gold Mine: Timmins, Ontario, Canada
For groundwater control, designed and supervised the construction of a frozen earth wall around the 3.5 km perimeter of an open pit mine. On-site freeze plants were designed to provide ground stabilization for eight years during excavation.
- Harbor Siphons: Milwaukee, WI
Two 15-foot diameter rock tunnels were constructed for the Milwaukee Metropolitan Sewerage District to correct deficiencies in the system. Grouting was performed before ground freezing was used during the excavation of two drop shafts and one riser shaft. Designed and supervised the rock grouting plan and ground stabilization system.
