One of the first major projects of the partnership included the second heightening of the Aswan Low Dam, which continued from 1929 through design and construction stages until 1933. In addition to dam and hydroelectric work, the company was also employed on irrigation, drainage and harbour works in England, Scotland, Spain, Portugal, Greece, Jordan, Iraq and Pakistan. Rail engineering services were also provided; Prowde's last major work was for the London Underground, removing unsightly railway bridges and viaducts across the Thames (he died in 1949).
