SERVICESReinforced Concrete Portals and Sprayed Concrete Lined (SCL) tunnels
The Kirtling Street site situated on the south bank of the River Thames will be used to drive the main tunnel to Carnwath Road Riverside in the west and towards Chambers Wharf in the east. It is in the central and largest section of the Tideway project (£746 million) which is being delivered by the Ferrovial Agroman UK and Laing O’Rourke joint venture.
Joseph Gallagher were contracted to construct the launch tunnels for the two Central Section Tunnel Boring Machines. The project consisted of 2no. 10 metre internal diameter, 37-metre-long SCL tunnels, and 2no. reinforced concrete portal frames (20m x 16m) containing approximately 280 tonnes of steel reinforcement. Our client also consulted us on the TBM launch enabling works, including launch rails and shoveframes. We were able to provide a solution to be undertaken concurrently with the SCL tunnelling package for a huge programme benefit.
“Joseph Gallagher Site Management were open and honest, providing information and responding well to issues that occurred. They were always in attendance in the daily briefings (days and nights). The initial SCL briefing to operatives was very good, using an interactive quiz to ensure operatives understood.”
