Context

The roof structure for the new indoor swimming pool at the Sport Centre Cents in Luxembourg was designed by the German architectural office Auer Weber. The ceiling was built using 23.75 metres long wooden elements, which enabled the long spans of the roof. The use of lightweight Kerto LVL (laminated veneer lumber) made it possible to build the roof structure fast and sustainably.

Challenge

The goal of the structural design was to create a wooden rib ceiling with deep cassettes which would match the large spatial volume. The dimensional stability of the Kerto LVL (laminated veneer lumber) web was a great advantage here. As a result, the engineers were able to develop the roof surface with precise torsion-resistant webs. To achieve stability from the outset and take advantage of a high degree of prefabrication, the Q-panel webs were joined in pairs or even three at a time to the elements.

Kerto LVL roof structure

The Kerto LVL web has a height of 1.1m and a thickness of 75mm. With its slim design, the structure spans an impressive range of 23.75m. There is also an unusual use of bearing surfaces, and the web in the bearing area has a very low carrying height. This was possible only because of the specific material properties of Kerto LVL.

Installation

The extremely long wooden roof elements were prefabricated at Holzbau Amann’s factory and delivered by extra-long trucks to the construction site. Although the elements are 23.75m in length, their installation was quick and required only two carpenters on site. The end faces were finished off with end panels, to finalise the appearance of the roof. Quite noteworthy are the bearing notches, which are very large when compared to the size of the elements (structural components). They are on concrete ring beams on one side and on precisely positioned steel beams on the other. This required the highest degree of precision from all those involved in the construction.

Outcome

Thanks to the high durability and form stability of the Kerto LVL web, the planned dimensions for the roof could be implemented in a slim structure. In this project Kerto LVL once again proved its capability as an efficient and millimetre precise construction material.
