280 Bishopsgate was designed by Foggo Associates and completed by Sir Robert McAlpine for the developer Hammerson. The facility is a commercial development of the highest order, within a key area of the City of London. The property has already been fully let to the Royal Bank of Scotland as sole tenant.
The vertical transportation subcontract was awarded to Mitsubishi Electric Europe at the beginning of 2000. The contract involved the supply and installation of 11 lifts valued at £2.3 million. This was made up of eight main passenger lifts, two fire-fighting lifts and one goods lift.
Mitsubishi's Inazawa works near Nagoya in Japan manufactured the equipment, and provided all controllers, traction machines, door operators, doors, guide rails, pit equipment and cars. The traction machines for the main passenger lifts used PML34A permanent magnetic motors of a compact design with double disc brakes.
One of the principal client requirements was best possible ride quality. For Mitsubishi, the key to minimising vibration and noise is in accurate installation of the guide rails. Placing a specially developed V gauge between the piano wires permits guides to be fixed to very small tolerances. All car and counterweight guide rails were installed and checked using this method.
Sir Robert McAlpine achieved practical completion of the building on 5 October 2001, two days ahead of the main contract programme.
