Text of a letter from the President of the Institution, Mr. D.A.G. Reid, CBE and the Chairman of the Council of Engineering Institutions, Sir Robert Wynne-Edwards, dated l2 May 1966: ‘Dear Minister, For some months past the Council of this Institution, together with the Chairman and some members of the Council of Engineering Institutions, have been giving anxious consideration to matters associated with the building of the new County Hall for the County of Bedford. You will, we are sure, be familiar with the case.'
Mr. C. B. Stone (Vice-president) said it was a common failing of consultants not to admit that their Structures leaked; however, he himself did not know of any case of leakage due to shutter ties. Mr. Jackson had shown there was a weakness but Mr. Stone thought that, if there had been a low water/cement ratio and thorough compaction by vibration, the cavity would not have formed.
Mr. D. G. ,Alcock (Associate-Member) writes:- ‘The authors claim to present a unified approach for the determination of the degrees of freedom or indeterminacy of plane and space frames. In fact the claim is rather ambitious as it can only yield the degree of indeterminacy of a structure which is already known to be stable.'
