he £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 be-
tween 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
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.
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 sup-
port is being provided by CH2M.
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.
The 360 tonnes front sections of the TBM, built in
Germany, were transported by sea to Rosyth and brought
by lorries under police escort along the M8 in central
Glasgow to the project site at Craigton in the south west
of the city.
Kobelco heavy-duty crawler crane was used during
excavation of two shafts down which the TBM will
eventually be lowered.
