Deep foundation for high rise in tricky soil conditions and surroundings in Scandinavia – Walkthrough of various high‐rise projects from initial geology to final execution and everything in between

This report explores the challenges and innovative solutions associated with constructing deep foundations for high‐rise buildings in Scandinavia. The focus is on three projects: Lighthouse and Mindet 6 in Aarhus, Denmark and Karlatornet in Gothenburg, Sweden. Each project faces complex geotechnical conditions, requiring advanced engineering techniques. The report highlights the importance of early involvement in project planning, allowing for tailored solutions to geotechnical challenges. Per Aarsleff A/S employed value engineering techniques to optimize designs, ensuring both cost‐effectiveness and structural integrity. Test piles were crucial in validating foundation designs, offering real‐time data for precise calibration. The report emphasizes the important collaborative approach between engineers, clients, and other stakeholders, leading to innovative design solutions and successful project execution. The strategic use of advanced machinery, such as Aarsleff's Bauer BG55 drilling rig, underscores the technical prowess required for these projects. The report showcases how complex soil conditions and engineering hurdles were overcome through meticulous planning, technology, and continuous collaboration, setting a standard for high‐rise construction in challenging environments in Scandinavia.
