Baby Arch Replica to Stand In Warren, PA recording the birthplace of the Gateway Arch at local PDM shop
November 4, 2014
On behalf of the Committee of Retired Boilermakers, we are writing to you in the hope that you could assist us in our quest for recognition for the men who worked for the Pittsburgh Des Moines Steel Company Plant in Warren, PA, more commonly known as PDM. From 1962 to 1965, there were approximately 280 men who worked on welding, cutting and fabricating the pieces that would be shipped by train and semi-trucks from Warren, PA to St. Louis, MO. Each piece had to be intricately cut, measured and ground to within 1/64 of an inch to make sure they would fit together perfectly with the other two pieces to form the triangle that began the base of each leg on each side. They were built continuously like that, only to be adjusted as the degree for the arch was adjusted.
