Pizzagalli Construction Company, the construction management firm for Canton-Potsdam Hospital's consolidated cancer center, has begun to clear the site on the main campus. A local well-digger has moved onto the site to prepare shafts that will become part of the new addition's geothermal heating and cooling system. Pizzagalli of Vermont has subcontracted a significant portion of the work to local companies, including firms from Canton, Gouverneur, and Malone. Construction is expected to last approximately 12 months.
