Civil engineering and infrastructure specialist Barhale has been awarded a second high profile flume construction contract on the Thames Tideway Tunnel.
The Ferrovial Construction and Laing O’Rourke (FLO) joint venture, the principle contractor for the 12.7km central section of the 25km Thames Tideway Tunnel, has appointed Barhale to carry out the works at the Blackfriars Bridge Foreshore site.
The contract follows on from the successful delivery of a similar contract at Tideway’s Central’s Victoria Embankment Foreshore site further west. Work will involve the installation of a flume inside the existing Victorian Low-Level Sewer with the Thames River Wall.
Fabricated by Barhale subsidiary BCS Group, the pipe will be made up of 41 rings of 10 individual steel segments. It will carry the flow of the sewer during construction works and will allow future breakthrough to connect the sewer to the Thames Tideway tunnel.

Tunnelling on the central section was completed earlier this month.
Filipe Mello, Barhale’s contracts manager at Blackfriars Bridge Foreshore said that the award recognises the delivery of the earlier flume installation which saw construction completed ahead of schedule.
He commented:
“While we undoubtedly took a lot of expertise and experience to the Victoria Embankment site, we also gained a great deal of insight which we will take to Blackfriars.”
“This is a challenging project that requires us to work inside the harsh and restrictive live environment of the existing Victorian sewer. It also presents severe logistical considerations. We will have to work at night and with access to the sewer often limited to tight three-hour periods.”
The flume will be an important step in the continued progress at the Blackfriars Bridge Foreshore site.
Completion is scheduled for May 2021.
