The first timber components have arrived at the HAUT construction site in Amsterdam. This marks the commencement of the timber construction phase of the iconic timber hybrid HAUT. It will be the tallest timber hybrid building in the Netherlands and is amongst the tallest timber buildings in the world.
Until this point, grey concrete was the primary visible material on the construction site along the Amstel river, forming the basement, part of the plinth and the elevator shaft. Hence the term “hybrid”. From now on contractors J.P. van Eesteren and Brüninghoff will progress with the timber phase of the construction.
Glulam en CLT
The first wooden elements to be assembled are for the supporting construction of the plinth. The beams and columns are made of glulam, laminated wood, where the layers of wood are glued with the grain running in the same direction. This provides extra strength in the length of the elements, resulting in extra load carrying capacity. It can be compared to the strengthening effect of a bunch of straws. In addition, some steel columns are used, which are later wrapped in a timber casing. The floors and walls of the main structure are made of Cross Laminated Timber (CLT). These are thick wooden panels of wood that, unlike glulam, are glued transversely.
Sustainable timber production
The building primarily uses spruce wood from sustainably managed forests of Austrian timber supplier Mayr Melnhof. The tree trunks are used in their entirety due to a no-waste production system, processing them into wooden planks, beams, panels and other end and residual products. An added sustainable advantage is that the carbon absorbed from the air by the trees during their growth is stored in the building as long as it stands.
From this point the building will be assembled at the rate of approximately one floor per week. We will post construction progress on our social media; Instagram, Facebook or Linkedin. HAUT is planned to be completed in the first quarter of 2021.
