Abstract
The Rank Hovis McDougall Centre in London was constructed at the intersection of two trunk roads and over two underground railway routes. One trunk road passes over the substructure. Protection from noise and vibration was necessary, and the building was double glazed as well as being mounted on resilient pads. It is the largest building in the UK to be mounted in this way. The mounting of a tower on these resilient type springs necessitated restraint to lateral translation movement and from movement due to steady and impact gusts of wind. This was achieved by ‘hard stops’ of adjustable flat jacks and bolts suitably isolated. Although noise and vibration are apparent in the basement car park, the level of disturbance from outside sources is not detectable within the insulated superstructure in spite of the very low level of background noise within the building.
