Giant Tunnel Boring Machine For Glasgow Tunnel

Giant Tunnel Boring Machine
For Glasgow

The £100m Shieldhall Tunnel, which at 3.1 (5 km)miles long will be five times longer than the Clyde Tunnel and at 4.7 metres in diameter big enough to fit a double decker bus inside, will run between Craigton and Queen’s Park.

It is a key part of Scottish Water’s £250m, five-year programme of work, launched in 2013, to improve river water quality and the natural environment and tackle flooding - the biggest investment in the Greater Glasgow area’s waste water infrastructure in more than a century.

The project will use a giant, state-of-the-art Tunnel Boring Machine (TBM) which will construct the biggest waste water tunnel ever to be built in Scotland.

Kobelco heavy-duty crawler crane was used during excavation of two shafts down which the TBM will eventually be lowered.

The 1000 tonne, 180 metre-long TBM, by German company Herrenknecht, reached a key stage recently when the cutting head was put in place at the front of the machine and the factory test was conducted.

The team involved in the Shieldhall Tunnel for Scottish Water, known as the Glasgow Tunnel Partnership, is a commercial joint venture between Costain and VINCI Construction Grands Projets called CVJV, with additional local partners George Leslie and AECOM. Technical support is being provided by CH2M.

Kobelco heavy-duty crawler crane was used during excavation of two shafts down which the TBM will eventually be lowered.

CVJV’s preparatory work on the Shieldhall Tunnel is progressing and is nearing completion. The TBM has been brought in several parts from Germany to Scotland.

The front sections of a giant, state-of-the-art Tunnel Boring Machine (TBM) have arrived in Glasgow ahead of the construction phase of the biggest waste water tunnel in Scotland.
