Aarsleff Grundläggning AB and Per Aarsleff A/S’ ground engineering and construction work for the Karlatornet in Gothenburg has been shortlisted in the Construction News Awards 2019 ‘International Project of the Year’ Category!

The Construction News Awards are celebrating 23 years of showcasing the very best in the industry. Having become the most prestigious and coveted awards in the construction industry, becoming a finalist in the Construction News Award is a well-recognised badge of excellence amongst clients and peers.

Ahead of the judging panel’s final decision, Aarsleff Ground Engineering’s Managing Director Kevin Hague will deliver a presentation at the Construction News Head Office in London.

This will give judges a more detailed insight into the collaborative approach which led to the Karla Tower project being shortlisted.

About the Project

There were many geotechnical challenges to overcome in this scheme. From the ground level, there was approximately 55-75 metres down to bedrock; and in between the ground mainly consisted of Gothenburg clay characterised with a very low strength and high sensitivity during excavation. In addition to this, there was a layer of frictional materials above the rock and a general risk of encountering large stones. Aarsleff Grundläggning AB and Per Aarsleff A/S overcame these challenges by drilling 2,000mm diameter bored holes using the Kelly method. This is a classic bored pile system which transfers torque (Torque is a measure of how much a force acting on an object causes that object to rotate) and vertical crowd force to drilling tools via a telescopic Kelly bar. Now that is has been proven that large and deep piles can be constructed in the Gothenburg ground to this scale, new developments within the city can be made without fear of ground conditions being the limiting factor.

The Construction News awards ceremony will take place on the 11th July at Grosvenor House Hotel in London.
