Last week's issue was full of woes of the Millennium Bridge and equally full of the relationships between engineers and architects (AJ 15.6.00). Stephen Haskins' letter suggesting that had 'Ove Arup put a little wobble into the London Eye then it would have got the credit due for that marvellous piece of engineering as well' is very wide of the mark in accuracy. Arup had carried out the scheme design for the wheel but had no involvement in the project after 1998.
The engineering design and construction was carried out by a series of trade contractors working under Mace as construction manager. Babtie Allnott & Lomax was the independent engineer and key consultant to the Wheel Trade Contracts.
Unlike the bridge, Marks Barfield has always gone out of its way to acknowledge the key role of the engineers on this project.
Also unlike the bridge, tuned mass dampers were installed prior to use, and are successfully keeping the very flexible structure extremely steady against dynamic movements.
