The Structural Engineer, Volume 45, Issue 3, 1967
Mr. Peter Mason (Member of Council), opening the discussion, said that he personally found the whole subject of immersed tube tunnels an extremely fascinating one. He was an engineer with a foot in both camps, both civil and structural. As a civil engineer he was very interested in tunnelling, but for the normal bored tunnel the part the structural engineer had to play was not quite so prominent as that of the mining and civil engineer. However, with the type of submerged tunnel that they had just been hearing about the structural engineer came into his own because the design of the tunnel sections was a completely structural problem.
A Code of Practice for timber has to take into account considerations ranging from forest economy to the changing effects of industrialization in the building and timber industries. In so far as it succeeds in its task it becomes an instrument of policy for the utilization of natural and industrial resources and in particular for improving communications between research and design. Rapid changes in industrial techniques demand a flexibility in codification which places greater emphasis on the importance of prototype testing and on a better understanding of the significance of behaviour characteristics requiring some re-alignment of research and design concepts.
