Nordecs Structural Frame for 27-Storey Office Tower in Central Oslo: A Key Component of the Spektrumkvarteret Development

Nordec has been selected to provide the structural framing for the Spektrumkvarteret project, a significant development in central Oslo, Norway. The project includes a 27-storey office tower and a congress building, and the contract involves the design, manufacture, and installation of a prefabricated steel-concrete structure.

The Spektrumkvarteret project is being developed by HENT with LPO as the architect, and is set at Sonja Henies plass. Nordec's contract encompasses the creation of 1,450m² of concrete walls for the congress building and 30,000m² of flooring throughout the complex, combining hollow-core alongside slabs.

The project's engineering highlights include the use of composite columns, welded beams, and a cantilever section that extends over the street. Installation work is scheduled to commence in February 2026, with a completion target set for October 2026.

Minna Kuusela-Opas, senior vice-president at Nordec, commented: "We would like to thank our customer for the trust we have received. We are delighted to be involved in implementing this important project in such a central location in the city. This project offers us an opportunity to showcase our expertise, and we are committed to doing our very best to achieve the goals set for the project. We look forward to working closely with the entire project team to ensure success."

With over four decades of experience, Nordec is a provider of frame structures for buildings, facades, and steel bridges in the Nordic countries. In April 2025, the company won a contract for the Lastaustie 7 project in Jyväskylä, Finland. Additionally, a month earlier, Nordec was chosen by NCC, a Nordic construction company, to design and construct the frame and envelope structures for a new train depot in Stockholm, Sweden.
