WHEN invited by the Chadwick Trustees to give this lecture the title, “Engineering Problems of Modern Building Construction,” was chosen for two main reasons:- Firstly-The name of Mr. Alfred Bossom, the sponsor of this series of lectures, is largely associated with modern building construction not only in this country but also in America. His keenness to improve both methods of construction and regulations governing design is well known. Secondly-A certain amount of ambiguity exists, in this country at least, as to the relative positions of the two professions, architecture and engineering, which merge in the field of modern building construction. Energetic steps have been and are being taken by both these professions to inform the public of their respective achievements. In national as well as professional fields true co-operation can often be furthered by a mutual appreciation of each other’s difficulties and problems. Such appreciation engenders mutual respect with the result that the public benefits. H. John Collins
Before describing the Unit-Construction bridges which form the subject of this paper, it is appropriate to consider briefly the procedure which normally has to be adopted before a given bridge of conventional type can be produced. The process is much the same whether the structure is for permanent or temporary service, at home or abroad, and can be summarised in three stages. C.O. Boyse
Mr. D. H. GREEN, O.B.E., M.C., B.Sc, M.I.Struct.E., A.M.Tnst.C.E., said that he was sure everyone had listened with great interest to this paper and had appreciated the tremendous amount of work that must have gone to its preparation with the extraction of all the historical details which the author had given them.
THE Institution’s headquarters are now established in the new premises at No. 11, Upper Belgrave Street, London, S.W.l. For some time past it was felt that the premises at No; 10, Upper Belgrave Street were becoming inadequate in view of the increasing activities of the Institution. Most important was the fact that the meeting hall could no longer accommodate the numbers attending the general meetings.
