Stone & Webster built their business from a base at Stoughton, Massachusetts into a multi-faceted engineering services company that provided engineering, construction, environmental, and plant operation and maintenance services. They became involved with power generation projects, starting with hydroelectric plants of the late 19th-century that led to building and operating electric streetcar systems in a number of cities across the United States.

As well as industrial plants, they built the 50-storey General Electric Building in New York City, the Cathedral of Learning at the University of Pittsburgh, a landmark now listed in the National Register of Historic Places, as well as buildings for Massachusetts Institute of Technology. Stone & Webster was the prime contractor for the electromagnetic separation plant for the Manhattan Project at Oak Ridge, Tennessee.{{cite web|url= http://scarc.library.oregonstate.edu/coll/energy/catalogue/energy2_101-178.html |title= History of Atomic Energy Collection, 1896-1991 |publisher=Oregon State University Libraries |date=2019-07-09 |accessdate=2019-07-09}}{{cite web|url= http://scarc.library.oregonstate.edu/omeka/exhibits/show/atomic/manhattan/detonation |title=The Manhattan Project |publisher=Oregon State University Libraries |date=2019-07-09 |accessdate=2019-07-09}}
