Since I started my research about tunnelling and railway engineering, I was wondering about all the production lines that are in operation in Paddington – Crossrail construction site that what exactly they are producing because I could only see clay and some other type of soils. In the same time I was searching that were all concrete segments that are used by Tunnelling Boring Machine (TBM) come from and so on. Finally yesterday I found out that they built their own concrete plant at the site! They have been producing all concrete and concrete segments for this project at the construction site which is in Old Oak Common! If I am not wrong other primary material has been imported from outside London by trains. Because I have been observing these trains passing Hayes and Harlington Station ( where I catch a train towards London Paddington station everyday!)and terminating at Old Oak Common area!
Cross Rail project is the biggest project in the Europe at the moment. And is the largest single infrastructure in the UK.
Therefore it is every engineer’s dream to be part of this challenging project, not only to work and make money but to learn more in every single day. However for some people, for instance students those are still studying for their first degree and are inserted in the tunnelling and railway engineering, a site visit from one of the contraction sites will be enough to learn and observe some engineering aspects in practice that they are learning in university.
On Friday (13th June 2014) a site visit from Liverpool street station was arranged by Oliver Brandt, the founder of Engineering think up club, for a group of UCL Civil Engineering student. This was the most valuable visit that I have ever had up till now.
In this visit after giving briefing by the operational manager, we visited from Moorgate Shaft, which will be used as ticket hall upon completing the construction. This shaft has diameter of 25m and depth 61m. To be able to imagine the scale, it is as deep in the ground as Moor House is tall. The following pictures are from the visit.
