In 1900 he was appointed Principal Assistant Engineer for Rivers, Water Supply and Drainage, and supervised the completion of the Sydney low level sewerage system, which was a pumping system to replace harbour sewage outfalls. Following this he was appointed to the Hunter District Water Supply and Sewerage Board. He returned to the Public Works Department in 1912, and had overall design responsibility for the steel Pratt truss–type Tom Uglys Bridge over the Georges River. He is also credited with designing his own type of Truss Bridge, the Allan Truss.
