The Shieldhall Tunnel – Tackling Glasgow’s Flooding Risk and Improving Water Quality with Dominic Flanagan, Major Projects Delivery Manager, Scottish Water.
The first Lecture of 2020 – The Practical Lecture – was kindly hosted by City of Glasgow College at their impressive Riverside Campus. Dominic Flanagan project managed the construction of the Shieldhall Tunnel on the Southside of Glasgow.
In June 2002 a month’s rain fell on Glasgow in just one afternoon leaving parts of Glasgow’s south side under several feet of water. A hugely ambitious project, the Shieldhall Tunnel is a key part of a £250m partnership programme to transform how the City manages rainfall to end uncontrolled flooding and improve water quality in the Clyde.
It is the biggest storm water storage tunnel in Scotland and represents the largest investment in the sewer network since Victorian times. The project involved the construction of a 5km tunnel wide enough to fit a double decker bus inside, and required considerable mine working consolidation along a challenging route that passed beneath three railway lines, three parks and the M77. More than 90% of all excavated material was recycled, and the £100m project was delivered within an astonishing three years.
Dominic provided an overview of the engineering complexities and stakeholder management challenges overcome during delivery.
