Blackfriars Bridge Foreshore
In order to excavate our 53m shaft at this site, we needed to first stabilise the ground around the perimeter to allow for safe working conditions. To start this process, we used a technique called jet grouting, which involves jetting high pressure water into the ground to loosen and partially remove the soil. The soil that remains in the ground is mixed with durable cement-based grout which sets, steadying the working area.
We created 138 grouting columns in total on this site with approximately 35,000tns of spoil being taken out of the ground, all of which has been taken away by barge.
We will now begin to insert secant piles around the perimeter before we begin digging out the shaft in the coming months.
Since our previous update we have been increasing the depth of the riverbed by carrying out dredging works. This is to accommodate the construction of the new connection culvert which will divert the current sewage overflow under Blackfriars Bridge to our new tunnel.
What are our working hours?
Standard working hours are 8am to 6pm Monday-Friday and 8am-1pm Saturday. Also, there is a 1 hour mobilisation period before and after the Standard Working Hours, plus maintenance periods on Saturday 1-5pm and Sundays 10am-4pm.
We are currently working to extended working hours of 6am to midnight Monday - Saturday. This includes quiet hours of 6am - 8am and 8pm to midnight.
There may be periods of continuous (24/7) working to complete marine works in close proximity to the London Underground Waterloo and City Line (near Blackfriars Bridge) and also for some of the shaft/tunnelling works. These periods will be minimised as much as possible.
Loading of barges and barge movements would take place within standard hours.
Details on the next Blackfriars Community Liaison Working Group (CLWG) will be updated shortly. If you are interested in finding out more about our CLWG please email [email protected].
