When in 1900 the American Bridge division of U.S. Steel acquired Berlin Iron Bridge, three of its executives, Daniel E. Bradley, George H. Sage and Seymour N. Robinson along with a number of engineers, draftsmen and other employees broke away to form The Berlin Construction Company. They leased a fabricating plant in Pottstown, Pennsylvania, and landed their first contract for a Power House in New Rochelle, New York, in January of 1901.

In October of 1901, the company purchased a piece of land from the Merwin Brick Company next to the railroad depot in Berlin, Connecticut. In 1902, a new plant was designed and fabricated at Pottstown for shipment to Berlin. By July 30th, 1902, the new plant had been erected on the former Merwin parcel, the Pottstown plant was closed and Berlin had become home to the company.

The Berlin Construction Company grew steadily, prospering through the early years of the century and into the roaring twenties, shifting its emphasis from the lenticular (steel arch) bridges that had made its name to providing structural steel for, and construction services for a variety of industrial structures and buildings. In 1911, Berlin's first president, Daniel Bradley stepped down and took a seat on the Board. George H. Sage, working with nine long-term employees took over as president. Other changes of the guard occurred when Seymour N. Robinson retired in 1919 and Daniel E. Bradley passed away in 1923. George Sage, the last member of the original team, remained in charge until he died suddenly in 1926 when Charles Chase took over.

Chase's tenure was marked by tough times. In 1944, after barely holding the company together through the depression and World War II, he turned the company over to the next generation. Berlin was reorganized under Albert H. Schilling and five partners, George B. Taylor, Clarence B. Baldwin, Clarence A. Johnson, Howard W. Smith and Paul A. Stahl. It was the start of a new and prosperous era. The company came back, growing in the boom that followed the War. They broke new ground in steel fabrication and building techniques. Modern equipment was installed, new parcels of land were added and capacity was substantially increased at the Berlin site. In 1962 they changed the name to The Berlin Steel Construction Company to reflect the fact that they had retooled extensively and were prepared to offer a wide range of steel specialties, services and fabrication to the construction industry. In the 1970's, when American manufacturing hit a rough spot and as the rust belt claimed any number of the types of facilities Berlin had been building, the company turned its attention and skills to the construction of offices and public buildings. You can see Berlin's work throughout Connecticut and the Northeast. In the 90's Berlin again changed direction in response to shifting markets. The FEI (structural) and Pillar (miscellaneous) plants were moved (literally) to Virginia in 1995 and 1996. The change of location has made Berlin more competitive in its traditional Connecticut/ Northeast markets, and created a strong presence in the mid-Atlantic area, leaving it well positioned for the future as it enters its second century. Berlin's varied history has created an important legacy that serves the company and its clients well... its ability to handle a broad spectrum of fabrication assignments, from conventional structural beams and columns to complicated weldments and trusses...which is why Berlin can be found topping off an urban skyscraper or working on the restoration of a 19th century steeple clock. Whatever the assignment, Berlin approaches it with integrity and creativity, endeavoring to deliver more than expected, while safely and economically meeting the most demanding schedules.
