When we started on site we needed to demolish the existing building on site and clear the site before our works could start. To enable our works to take place we also needed to increase the size of the site. To achieve this we built out into the river to create an area of new land in the river foreshore by building a river-wall known as a ‘cofferdam’ out of sheet piles.
Since then, our site teams have been hard at work to build a shaft that will allow us to begin works on the main tunnel. The walls of the shaft have been completed and the Museum of London has now completed their archaeological dig on site to protect any items of historic importance.
Update- 14 June 2019
We excavated the shaft to 60 metres deep. The remaining four metres will be excavated into a curve, within which the base slab will be formed. The concrete batching plant was delivered. This will sit inside the acoustic enclosure and will be used to concrete the secondary lining of the shaft, eliminating the need for concrete to be delivered to site for this phase of works.
We concreted the first bay of walls for filter press. The bays will store material dropped from the filter press (part of the slurry treatment unit - STP), before it is transported to the muck bin. More acoustic cladding was placed on the de-sanding unit, also part of the STP.
Next week We plan to start lowering reinforcement cages into the shaft to start forming the base slab, before concreting.
Concrete trials are planned with the new batching plant and we will also start building the second bay of walls for filter press, there will be four bays in total.
In July we will be undertaking the continuous concrete pour for the shaft’s base slab. This will involve pouring concrete continuously for a period of approximately 36 hours. If you feel you may be affected by this work, please see below an Information Sheet about mitigation which may be available to you. May 2019 - 36 hour concrete pour for base slab
Permanent above ground structures
We have submitted the applications for the permanent above ground structures for Chambers Wharf to LB Southwark. These structures include the ventilation columns, the electrical and control kiosk, the stand-alone artwork and the new river wall. As these structures are permanent, they will remain after the Tideway construction works have been completed.
Please find a link below to the LB Southwark website and reference numbers for the submissions: https://planning.southwark.gov.uk/online-applications/
Ref: 19/AP/1415 - for the ventilation columns, electrical control kiosk and stand-alone artwork. Ref: 19/AP/1465 – for the permanent river wall.
If you wish to comment on these applications, then please ensure you do so directly to LB Southwark. The closing date for comments is shown on the LB Southwark website.
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.
Certain activities within the river foreshore and those that are dependent on the tide, may take place between 5am and 10pm. These activities may include: barge movements, filling the cofferdam, installing tie rods and relocating filling material.
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 next Community Liaison Working Group meeting will take place on Monday 15 July, 7-9pm at Wade Hall
Previous minutes are available upon request, please contact the Tideway Helpdesk on 08000 30 80 80 or email [email protected]
All static machinery and plant will be screened or enclosed
The excavated material handling area will be enclosed
Noise enclosure over tunnel drive shaft during main tunnel construction
Noise-generating activities will be located as far away from sensitive receptors as possible
The contractor will use best endeavours to position offices and storage containers in the site layout to act as noise barriers, with consideration for loss of light on adjacent properties
No scheduled lorry movements will take place between 8:30 to 9:15 and 15:00 and 15:45 during school term time and traffic marshalls at Jamaica Rd to stop construction deliveries during this period
Vehicle movements outside of standard hours will be restricted
Acoustic barriers will be installed on the cofferdam
Signage will be provided for pedestrian diversions to clearly identify alternative routes during construction
No loading/unloading or movement of vessels at night (22:00 to 8:00)
