Riverside South is part of the continuing development of Canary Wharf by Canary Wharf Group, and will be the UK headquarters for Morgan Stanley. It is located on the western side of the Isle of Dogs, immediately south of Westferry Circus on the edge of the River Thames, one of the few sites left in the Docklands area which had been identified as suitable for the construction of skyscrapers.


Canary Wharf Riverside South comprises two towers built on either side of the Jubilee Line running tunnels with a third, lower structure built over the tunnels and intervention shaft. Tower 1 of the scheme is 235 meters tall whilst Tower 2 is shoter at 186 meters.


It is envisaged that the lower levels will form open trading floors running through all three structures. The monitored section of the Jubilee Line comprises 2 curved running tunnels, 220m in length interconnected with adits an intervention shaft that is approximately 30m deep.



Live tunnels

Sixense installeda total of 6 Nos.  CYCLOPS Automated Total Stations to provide automated three dimensional monitoring of the live tunnels to provide assurance that the tunnels are responding within acceptable limits before, during, and after the construction period.


To provide redundancy to the remote system, manual monitoring has also been undertaken.


The shaft monitoring equipment includes automatic long range wire crackmeters that run the full height of the shaft, electro-level beams installed within each adit, and vibrating wire crackmeters installed across construction joints within the intervention shaft and adits.


All of the information acquired is imported into Sixense’s Geoscope monitoring software, permitting real-time access to the monitoring data by the client, their consultant (Arup) and also Sixense’s monitoring engineers to allow remote maintenance of the monitoring system.
