Summit Engineering provided the structural design for this new 60,000-SF, five-story office building. The building is sited at the former location of a six-story mill building. Existing stone and clay masonry foundation walls, pits and turbine shafts from the original mill building were considered historically significant and could not be removed or altered. The design of the steel framed building structure was required to imitate the original building loading and had to incorporate the existing foundation elements without adjustment.
