Mr B. Clancy (F) (Brian Clancy Partnership): Could the authors say what problems, if any, were encountered in keeping the pile casings vertical during driving/sinking?
A Union view of elections to the Engineering Assembly Mr John Lyons, the General Secretary of the Engineers' & Managers' Association and also a member of the Engineering Council, has voiced strong criticism, in the June issue of his union's journal, of the four major engineering institutions. The targets for his criticism are the lists of selected candidates for the elections to the Engineering Assembly published by each of the institutions. The comments made by Mr Lyons, which may be of interest to our members and which have been extracted from the press release, are as follows: The Assembly, as a vehicle for the views of the profession, faces the possibility of being stillborn. If this happens it will be down to the actions of the four major engineering institutions, who have set out in an organised way to secure as many seats as possible for their own chosen nominees . . . to the detriment of smaller institutions.

Building work on the French Pantheon (the Church of Sainte-Genevieve) was started in 1756, and there was a celebrated dispute, in 1770, as to whether or not the crossing piers would be strong enough to carry the projected dome. In the event, the piers were indeed found to be defective, but not for the reasons originally suggested. The technical history of this building is presented in this paper; the form of construction led effectively to a thin skin of each pier carrying the entire load. Local stress concentrations then produced the splitting and spalling observed in the piers. Similar defects may be seen in some crossing piers of medieval cathedrals; although the details of construction are different, medieval piers, as those of the Pantheon, can have weak central cores.
