Crossrail Time-lapse: Construction of Moorgate access shaft

The western ticket hall for the new Crossrail station will be constructed in Moorgate and will involve enlarging the existing Moorgate Underground Station and ticket hall in Moorfields.
A 42-metre-deep shaft has been built next to the existing station with piles 60 metres deep and steel reinforced concrete rings to secure the permanent structure for the next 120 years.
Construction of the Moorgate shaft at the new Crossrail Liverpool Street station is complete.
The shaft will provide ventilation and emergency access to the new ticket hall. The three-year project was concluded when BAM Nuttall/Kier Joint Venture successfully poured the base slab to the 44m deep shaft.
Work has been underway since October 2013 to construct the shaft, before reaching the bottom in September this year and commencing the base slab construction.
The focus will now be on the team to prepare the site for the arrival of the tunnel boring machine (TBM) Victoria in early 2015. From here she’ll make her final push through to Farringdon.
Moorgate shaft construction facts and figures:
The 42-metre-deep shaft is being built next to the existing Moorgate station, and is one of Crossrail’s most constrained sites, with the Hammersmith & City and Northern lines nearby
The final concrete pour of 1,800m ³ is one of the largest on Crossrail and took 17 hours to complete
For this pour, 225 lorry loads of concrete were used from three batching plants around London
Two of the three concrete pumps used are the largest in the UK and ensured a continuous supply of concrete for the two-metre-deep slab
The construction of the Moorgate shaft is taking place in one of Crossrail’s most constrained sites with the Hammersmith & City Line to the north, the Northern Line to the east and the existing Moorgate station ticket hall nearby.
