Technical expertise and sustainable solutions in Reykjavik
KI Consulting Engineers has played a central role in the development of the new Hyatt Centric Reykjavík, a project where existing concrete buildings are preserved and integrated with modern additions in concrete, steel and wood. As structural engineers, our work has encompassed the load-bearing structures from foundation to roof, including the concept for a self-supporting CLT facade, where we have focused on creating solutions that both meet strict technical requirements and support the project's sustainable ambitions.
Frederik Lybek Lind, project manager at KI, talks about the work with the existing buildings:
"An important part of our early work has been to assess which existing parts of the buildings could be reused without compromising functionality and buildability. By combining our experience with modern analysis tools and LCA analysis, we have been able to find solutions that are both economically and environmentally sustainable."
Self-supporting facade elements with reduced material consumption
Frederik also highlights the facade as a particular challenge:
"We have designed the facade elements as self-supporting Vierendeel lattice structures made of CLT (cross-laminated timber). The structure utilizes the rectangular holes in the CLT frames to create space for windows in the facade, while the moment-resistant corner joints ensure the necessary stiffness and static effect. This approach made it possible to reduce material consumption, control deformations precisely and ensure that the requirements for the window frames are met. It has been an exciting process, where we have gained increased insight into working with CLT as a material."
Multifunctional lobby and staircase with complex geometry
The project's exciting architectural design has also required complex solutions, including a multifunctional lobby with few supporting columns, a main staircase with advanced geometry, and a roof terrace with a winter garden.
For KI, the project has been an exciting opportunity to combine our technical expertise and modern calculation tools with a sustainable focus. Our many years of experience with projects in Iceland have given us a solid foundation for creating sustainable solutions for new construction and modernization projects with respect for local norms and traditions across borders.
