 Many men of the congregation volunteered to transport the materials to New Kensington . The congregation found a contractor , Mr. Charles Camarata , to direct the free labor . Camarata had built hundreds of miles of road in the state of Pennsylvania and around the country . In addition , he had constructed homes , civic buildings , and churches . As soon as he agreed to take the job in December 1940 , he split the volunteers into three groups . Camarata personally supervised the first group , which removed the marble from Mellon Mansion . The second group transported the marble to New Kensington and the third placed the materials on the grounds of Mt . St. Peter . This project started on December 13 , 1940 , and continued until May 26 , 1941 . The process was difficult and time consuming , made more difficult by the harsh winter of 1940 – 1941 .
