The Foundry History

The site of The Foundry and Bay 4 are filled with industrial history dating all the way back to 1869! Almost 150 years ago, Joseph Sidney Seaman started a small foundry at the corner of Liberty and 25th street. This particular foundry developed and produced George Westinghouse's locomotive air brake. Eventually, Westinghouse purchased this particular foundry and Seaman constructed a new foundry on 42nd street, where the Bay 4 structure now stands.

This foundry was first home to Seaman-Sleeth Co. that produced large steel shapes and rolls to be used in Pittsburgh's booming mills. The company prospered and in 1917, merged with Phoenix Roll Works to create Pittsburgh Rolls Corporation. Another change in management came when the Blaw-Knox Corporation took over in the 1930's and operated until the early 1980's when they, and other notable foundries, were forced to close due to overseas competition. 

A few years later, Mill Equipment & Engineering Corporation (MECO) took to the large industrial site and engaged in large machining and finishing of mill equipment. MECO and its successor entities, CCR Holdings and HSE Limited filed bankruptcy and begin liquidation in 1999. In 2000, Alexander Simakas formed Interlocking Deck Systems International (IDSI) and endeavored to enter into the business of manufacturing steel grid bridge decking. IDSI was the supplier of steel grid deck, solider piles, and other important bridge, highway, railroad, steel mill and energy related projects across North America. IDSI was sold in 2010 to Pittsburgh's L.B. Foster Company and ceased operation in June of 2011. 

Simakas then formed Fort Willow Developers and began master planning for the entire site in 2013, which included, you guessed it, an apartment building! The site itself has an incredible story, but Fort Willow decided to pay homage to Lawrenceville's heavy industrial past by retaining the steel frame of Bay 4. Bay 4 will become a unique public plaza built from a reclaimed artifact for community use and events.
