The front sections of a Herrenknecht TBM have arrived in Glasgow ahead of the construction phase of Scottish Water’s US$160M project to build the biggest wastewater tunnel in Scotland.
The 360 tonnes front sections of the TBM were transported by sea to Rosyth. The TBM, whose remaining parts are being delivered and assembled in the next few weeks before starting the construction of the 4.7m i.d. Shieldhall Tunnel in the summer, will weigh 1000 tonnes and be 180m long. The tunnel will follow a 5km long route between Craigton and Queen’s Park.
It is a key part of Scottish Water’s US$400M, 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.

Preparatory work for the tunnel is progressing and, following the start of the actual tunnelling in the summer, the construction phase is expected to take more than a year to complete.
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.
