The main challenges for the structural design of the scheme were achieving the height of the building whilst ensuring lateral stability and limiting dynamic response of the tower. There was also a late change in construction to precast columns in place of in-situ which had to be accommodated to achieve the programme deadline.
The foundation solution also presented a challenge as the site had been developed previously and there were numerous obstructions below ground including existing piles, works associated with the diverted Channelsea River and an abandoned culvert which was in close proximity to the crane base.
There was also a requirement to maintain structural separation between the three different demises of the scheme (academic, student and residential).
The crane scheme was also a challenging aspect of the build as two tower cranes at approx. 100m height were required to be free-standing, which imposed significant loads on the foundation.
