As I read Professor Horne’s paper I too had a very strong feeling of deja vu but for an
entirely different reason from that in the penultimate paragraph of the paper. I was educated through school and university in Glasgow and spent the first l1 years of my professional career there. I have spent the last 10 years in the Far East and in the Midlands of England where schooling and university entrance requirements have followed the A-level system. I have, therefore, been in a good position to compare the Scottish system of Highers combined with a 4-year university course and the English system of A levels combined with a 3-year university course. My conclusions, which are in no way nationalistic, are that the Scottish system provides a better balanced engineering education and seems to be similar to the ‘Access in engineering’ scheme referred to in Professor Horne’s paper.
The Working Party on Quality Assurance has now submitted its report to the Engineering Committee-the following is a summary of its deliberations and recommendations. We make no apologies, however, for the fact that much of what follows has already been stated in various meetings and open discussions within the Institution and many of its Branches.

This paper examines the applicability of the plate bonding technique to strengthen structurally damaged rein forced concrete beams. Two types of strengthened beam were tested. In the first, beams loaded up to 70 % of their flexural capacity were unloaded and strengthened in the unloaded state. In thesecond, beams also loaded up to 70 % of their flexural strength were reinforced with bonded plates while under load. The structural behaviour of these two types of strengthened beam is reported in terms of deflection, concrete and steel strain, cracking behaviour, flexural stiffness and strength. It is shown that strengthening, by bonding steel plates, of significantly cracked beams is structurally efficient and that the plated beams are restored to stiffness and strength values superior to those of the original unplated beams. The data show that complete confidence and reliability can be placed in applying the technique to structurally damaged members. The repaired composite beams are able to preserve their structural integrity and maintain composite action until failure. Further, the composite structural system obeys simple laws of mechanics right up to failure.
