During an excavation job at O’Hare in Chicago, electric power supplied to the large international airport was potentially at risk, as Electric Conduit Construction conducted drilling and digging activity onsite. Foreman Tony Gradi remarked that his crews always do their due diligence. They take the time to verify locate marks on the jobsite. The crews also use safety measures such as vacuum excavation and hand digging to expose electric conduit underground. In this way, they are protecting, vital utility services and keep their workers and the public safe.
