Like his brother James, Arthur was a Public Works Department cadet (under Blair) and then an assistant engineer in Westport.
He was then asked to join Harry Higginson's practice, where he stayed until 1881, when he went to New South Wales to survey the Goulburn-Cowra section of the Main Southern railway line.
In 1885 he had introduced an improved method of signalling drivers and guards on the trains.
In 1889, at the age of 35, Arthur died of typhoid fever in Wellington during an outbreak of the disease, [4][5] leaving a widow and three young sons.
Wellington sewerage was then collected in open drains (see Katherine Mansfield House; this prompted Harold Beauchamp's move to Karori).
