The project involved the upgrading of the existing building services for the Dundee head office, both front and back of house. A new customer banking hall was also created at the main entrance to the premises. The works were undertaken when the head office was operational and outwith normal working hours. Whilst the works were being undertaken, it was critical that the banking functionality remained fully operational, with no downtime permitted. The services works were fully designed and installed to ensure this client requirement was met.
