The seventh in the series of Surveys undertaken by the CEI was conducted in the summer of 1979. The results as applying to all chartered engineers, etc., were published in December 1979. Copies of the full Survey can be obtained from the CEI, 2 Little Smith Street, London SWIP 3DL, price £5. Corporate members and Graduates of the Institution were invited to complete and return survey questionnaires distributed with The Structural Engineer in May 1979. A sample of Associate-Members received a separate questionnaire at about the same time. A total of some 28 000 questionnaires were processed. Because the response from chartered engineers and Graduates in each institution was not strictly comparable to the size, a simple weighting procedure was again adopted to correct any imbalance.
