AB Invest and Norwegian contractor Hent have entered into a turnkey contract to build Mjøstårnet in Brumunddal, Norway, constructing what is said to be the world's tallest wooden building.

At the same time, Hent has entered into a contract with Moelven Limtre. The company, based in Moelv, Norway, will be the turnkey subcontractor and will supply glulam (glued laminated timber), Kerto and cross-laminated timber structures for the tower structure and swimming hall in the project.

Marketing and development director of Hent Knut Alstad said the project was the result of a development collaboration between AB Invest as client, Hent as project developer, and turnkey contractors Voll Arkitekter and Moelven Limtre.

Mjøstårnet will cover around 15,000m2, will span 18 storeys and include apartments, a hotel, offices, a restaurant and associated common areas. The total height will be more than 80m.

The value of the contract to Hent is around NOK 500 million (€56 million), excluding VAT. For Moelven Limtre, the contract with Hent is worth NOK 47 million (€5.2 million), excluding VAT.

Planning is under way, and work at the building site will start on 1 April 2017. The project will also include a 4,000m2 swimming facility with the Mjøsa lake as its closest neighbour.

Client Arthur Buchardt said, “The main structure is based on glulam, with slab elements consisting of a combination of glulam and Kerto, and façades as wooden elements. This is a response to the ‘green shift’ and proof that wood is a material that can compete with traditional solutions in high-rises too, enabling climate-friendly building as long as one has the right mindset.”
