Mersey Tunnel Project Case Study

Gnat's BROKK team overcomes difficult access problems during Mersey Tunnel Improvements

This Project involved the boring out of interconnecting Safety Tunnels between the two traffic lanes in the heart of the tunnel. The location and the site conditions presented the contractors with a number of practical and technical difficulties:

• Access time was at an unavoidable premium
• Working conditions were cramped
• Ventilation in the confined working area was limited

Solution

Gnat UK's dedicated BROKK systems provided the logical solution. The rubber tracked Brokk 250 proved the ideal choice with its combination of small footprint, focussed power, manoeuvrability and fume free 3 phase electric power source.
Gnat's skilled operatives negotiated the difficult access problems enabling the tunneling project to be completed safely, quickly and within budget.
