Project Focus: Karla Tower, Gothenburg, Sweden

The Karlatornet (Karla Tower) forms part of the Karlastaden project in the Lindholmen district of Gothenburg, Sweden.  At 73 floors and 245m high, the tower will be the tallest building in Scandinavia and is currently under construction, scheduled to be completed in 2021.

The tower has a square footprint of 33x33m, with a series of "twisting" floors above mid-height to create a distinctive architectural feature. The tower’s lateral stability is provided by a central RC core working in conjunction with two double-storey-height PT outriggers and RC perimeter belt walls.

The tower’s complex substructure comprises 56 end-bearing RC bored piles of 2m diameter, extending to a depth of up to 60m and socketed a further 3-4m into the bedrock.

Dr Karl Micallef 

Karl joined the Structural Engineering group at SOM London in September 2015, where he is currently working on the United Nations Offices at Geneva project and Nine Elms Square in London. Karl graduated with a Bachelor of Engineering and Architecture degree from the University of Malta in 2006, after which he worked with DeMicoli+Associates on various projects in Malta and Libya.

He read an MSc degree in earthquake engineering at Imperial College London and after working in the field for a year pursued to do a Ph.D. also at Imperial College London. His research investigated the response of plated structures to blast loading and how use of high performance steels and novel polymeric composite materials can be used to mitigate damage.

Prior to joining SOM, he worked at Foster+Partners for 2 years. He is a chartered engineer and remains active in academia by assisting in monitoring student design projects at Imperial College London and delivering taught and design modules at the University of East London.
