Most organisations that I have been involved with in the UK and abroad give a nominal life to all their major assets, e.g. buildings, earth retaining structures, bridges, and also heavy mechanical plant. In the case of immovable structures, annual maintenance budgets are allowed for, following regular routine inspections. The structures are then maintained to ensure the life expectancy is not jeopardised. For mechanical plant, the owner raises charges against works on which it is being utilised. When maintenance costs reach a prohibitive level, the plant is renewed with accumulated funds. Mr. M. Arshad

The paper describes the structural design of the new building from inception through to the analyses carried out during the construction period. Particular emphasis is placed on the extensive wind tunnel testing and dynamic analysis and the studies developed from them. The use made of prototype testing of principal structural elements is explained, together with the detailed studies of movements both in the ground due to excavation and in the superstructure during and after construction. The paper is structured into the following sections: G.J. Zunz, M.J. Glover and A.J. Fitzpatrick
Design of steel beams In June, we published a letter from Mr A. W. Durley on the rapid design of steel beams and included extracts from his design tables. Mr P. H. Allen, of the British Constructional Steelwork Association, has now written: I was interested to see Mr Durley's approach to the production of safe load tables for use in his office, in which reference is made to BCSA tables. This is a further example of what can be done to make the initial selection of steel sections a simple process. Verulam
