As announced in the March 1971 issue of The Structural Engineer (page 112) the Council awarded the 1971 Drury Medal to Mr. Peter Ellis, an Associate-Memberaged 24. The design submitted by Mr. Ellis was for an elevated tank for supplying water to an exhibition site. As well as the Drury Medal, Mr. Ellis receives a premium of £100.
Mr. J. S. Trentham: It was obvious that this job was going to be one of great interest from the very beginning although nobody envisaged that it would receive the Concrete Society Award for 1971.
Erskine Bridge, over the Clyde estuary, is a multispan road bridge with the dual two-lane carriageways, footpaths and cycle tracks carried on a continuous high yield steel box girder of trapezoidal cross-section. The main span, of 350m (1000 ft), is stayed by single cables over centre towers above the main Piers and anchored in the median. The bridge is notable for the economy of material: steelwork in the superstructure weighs only 298 kg/m2 (61 lb/ft2) of deck area and steelwork plus mastic road surfacing 393 kg/m2 (80 lblft2). The cost of the bridge has been correspondingly attractive: £124 per m2 (£11.5 per ft2) of deck area.
