Active Tunnelling have recently completed four tunnels at RAF Lakenheath for Fitzpatrick. The work involved constructing a 110m long 1200 dia tunnel under the main runway in 4 days and three other tunnels between 60m and 80m long under five taxiways with minimal cover, whilst working in very sensitive environment on an operational fighter base. Active Tunnelling performed there works safely, to programme and provided a quality finished product. I found working with Active Tunnelling a pleasure and would have no hesitation in employing their company again.
