About Friba Hossaini

I am studying Civil Engineering at UCL. I am interested in tunnelling and sky scrapers!

Basic information about Shanghai Tower

  • The building stands approximately 632 metres (2,073 ft) high and has 128 stories, with a total floor area of 380,000 m2 (4,090,000 sq ft).
  • totalling 121 floors
  • has a glass façade
  • In 2013, a Gensler spokesman described the tower as “the greenest super high-rise building on earth at this point in time
  • The design of the tower’s glass facade, which completes a 120° twist as it rises, is intended to reduce wind loads on the building by 24%
  • the building’s heating and cooling systems use geothermal energy sources

New Project at new Season of Engineering Knowledge Club (UCL)!


Based on my last year research project in Engineering Knowledge Club, which was about tunnelling and rail ways, I found myself interested in foundation of skyscraper and their impact on underground structures! I anticipate that I will complete this project in the new season of the club
For this proposes I would like to expand my research on 10 different tall buildings as listed below:
1. The Shard
2. The Gherkin
3. Burje Al- Khalife
4. Cheese Greater
5. Shanghai Tower
6. One World Trade Centre
7. Milad Tower
8. PETRONAS Towers
9. Wind Turbines
10. Taipei 101
I would briefly estimate the weight of each building and then types of their foundations. I believe this will help me to understand that how they function.

Crossrail Concrete Plant

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!19751_c300-410_bfk02_old_oak_common_segment_factory_31749



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. You might also find them interesting.
