            surely changing as these “mountains of gold” as some
            people called them, are reworked and removed.

            neering  national  office  is  situated  in  the  Thornhill
            Office Park in Midrand from where it serves its 10 000
            members as at 2013. Although the Institution was es-
            tablished in 1903 in Cape Town it became apparent that
            it should be run from Johannesburg and over the years
            it occupied various rented premises until it was time to
            come home in 2005 to its own building known as SAICE
            House.
