Chambers Wharf

We are currently working in the bottom of our 64m deep shaft on the portals, which are openings through which our tunnel boring machines (TBMs) will pass.

We have broken through the shaft's diaphragm wall's to create the sprayed concrete lined (SCL) underground chambers, known as ‘adits’ . The adits will be used as a launch area  for  our tunnel boring machine (TBM) Selina to be assembled and moved into place, for her underground journey to Abbey Mills. 

We are also carrying out electrical installation works within the slurry treatment plant (STP) as well and installing their acoustic enclosures. The STP will separate materials excavated during tunnelling, before it is taken away from site by barge.

Earlier this year, Chambers Wharf was the first site across the project to complete secondary lining to the shaft. More than 4,000 cubic metres of concrete was poured to create the shaft’s inner lining, which was built using a construction method known as ‘slipform’, a system of concrete formwork that is raised vertically to allow the concrete to be poured in one continuous process. 

Tunnel Boring Machine (TBM) Selina

Selina, our TBM which will construct the east section of the main Tideway tunnel between Chambers Wharf and Abbey Mills, arrived to site  8 July. Selina Selina was transported from Rotterdam using a 60m long bespoke Jack-up barge called ‘The SkyLift 3000’ - a purpose built marine heavy lifting barge, capable of lowering and lifting itself into and out of the water with very heavy loads on its deck.

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.

Continuous working will take place within the acoustic enclosure 24-hours per day, Monday to Friday. The doors of the enclosure will be closed for the night from 6pm to 7am, although there may be occasions when they are re-opened in the evening (up to 22:00) for plant movements. 

Certain activities such as barge movements within the river foreshore and those that are dependent on the tide, may take place between 5am and 10pm. 

Extended working hours are required for the main works to allow major concrete pours for shaft construction.

There will be approximately 33 months of 24-hour working. However, during this period activities will be predominantly below ground.

The last CLWG was held (virtually) on 29 June 2020, minutes and slides can be viewed below.
