British Telecom Deep Level Tunnels

Leak sealing and joint repair of tunnel liner rings containing Chrysotile.The BT Deep Level Tunnels are a series of tunnels that contain communications services (cables, fibre optics etc) underneath major cities. These tunnels stretch for some twenty-five miles and criss-cross the capital at an average of 30 to 40 metres below the surface with many access and egress points. Some of these, such as those situated underground by the Palace of Westminster, even have their own armed guards at all times.The unusual environment of these tunnels meant that many hazards had to be mitigated, notably poisonous gas and fire safety. Our Operatives and Supervisors who worked on this project had to undergo specific three day training on the specific Health and Safety issues associated with these works. All personel were required to utilise Drager gas warning monitors and oxygen re-breathers at all times on site.Our client had a tight programme with the refurbishments taking place over an eighteen month period by our team of thirty Operatives and Supervisors.
