Taller, stronger timber buildings for growing urban areas
Have a look at how Moelven Limtre constructs multi-storey buildings in dense areas on The Explorer; a digital showroom for Norway’s green and sustainable solutions.
Q&A about Mjøstårnet
Construction of Mjøstårnet is now completed. The 85.4 m high building was opened in March 2019 and is officially the world's tallest timber building. Mjøstårnet has a combined floor area of around 11,300 square meters. The building has 18 storeys that include apartments, a hotel, offices, a restaurant, a rooftop terrace and common areas. Next to Mjøstårnet there is a swimming hall about 4,700 square meters in size. This is also built in wood.
You can book a hotel room or meeting room in Mjøstårnet by contacting Wood hotel.
Moelven Limtre will supply glulam columns, beams and diagonals, CLT elevator shafts and stairs, and Trä8 floor slabs for the tower building and swimming hall in the project. The Trä8 concept was developed by Moelven Töreboda in Sweden. Moelven is responsible for the installation of all wooden structures. The consulting company Sweco performs structural design for Moelven.
Groundwork started in April 2017 and the first construction started in the beginning of September. The building will be assembled four storeys at a time. There are a total of five construction stages. Mjøstårnet will be built without external scaffolding. Instead, the project will use a large crane and internal scaffolding.
First the glulam structure is assembled on the ground next to the building, before being hoisted up and in. Then the floor slabs are hoisted into place. Ringsaker Takelementer AS will install the external façade, before Moelven proceeds with assembly upwards. The building is scheduled for completion in March 2019.
Hent AS's contract is valued at about NOK 500 million excluding VAT. For Moelven Limtre the contract with Hent AS is valued at NOK 47 million, excluding VAT. This is one of Moelven Limtre's largest contracts ever.
Glulam is wood that has been planed and then glued together to form strong columns and beams. Glulam may also be moulded into different shapes, for example arches. Glulam may be used as the main structure in the same manner as concrete and steel. As a construction material, glulam is cost-effective, fire resistant, strong and pliable.
Wood stores CO2 throughout its life cycle, and the glulam production process requires little energy. Tall buildings with load-bearing structures in glulam therefore have a very low carbon footprint. Wood is the only renewable building material we have.
