British Telecom - BT Tower, WC1 The BT Tower provided ACS with one of the greatest challenges of its 12 year history. Having remained closed for over 20 years, BT decided to open two ground floors and floor numbers 33-36 for corporate hospitality and internal functions. The deadline was Red Nose Day when the tower would be used to launch Comic Relief. Our brief included all common areas, catering areas, reception and technical floors. The programme required 24 hour attendance and no room for error. The results were spectacular, within programme and within budget. Back to Commercial Sector.
