it occupies the major part of the wall, high on the southern side of the banking chamber. Another major sculpture was a free standing aluminium and fibreglass figure by Donald Brook, also "Untitled". This was installed in 1965 in the roof garden but was removed when the atrium was converted to office accommodation and now resides with the Canberra Museum and Art Gallery. Throughout the life of the building changes have been made to the structure and fabric of the building and services upgrading has occurred as technological change exerted its influence. Maintenance work occurred in 1972, 1977 and in 1978 the telephone, lighting and electrical services were upgraded. The Department of Works made internal alterations and additions in September 1978 and replaced the external mosaic tiles with marble cladding in April 1981. The Department of Transport and Construction supervised a major refurbishment for the building in 1983 including redesign of the ground and first floor in January 1983, a refurbishment of the entrance canopies in February 1983, upgraded ground and first floor toilets in May 1983, and new mechanical services in August 1983. In October 1988, the Department of Housing and Construction designed a roof replacement and internal refurbishment. The principal result of all these alterations and additions was the infilling of the atrium to provide additional accommodation and the redesign of the cash handling area as that function changed. Further alterations occurred in 1994 to convert surplus accommodation for letting to tenants. This work included refurbishment of the independent entrance on the northern side of the building with a granite floor, a marble, granite and stainless steel stair, a skylight over, and the partitioning of the first floor space into offices. Alterations to the buildings in recent years illustrate a change towards a cashless society. The original building design reflects the money-handling nature of banking in a cash-oriented society. The design of the Reserve Bank and its operation centred on the receipt and distribution of cash. The careful arrangements for receiving cash in a secure cash handling area, the location of the strong room in the centre of the building, the bold, wide (but carefully uncluttered) public counter together with the scale and overwhelming impressiveness of the banking chamber were all meant to give a real sense of security as well as provide a perception of the significance and importance of the role of the Reserve Bank in
