Freeway depot, Loveresse BE
2017
The highest precision was required for the workshop on the A16 freeway in Loveresse in the Bernese Jura. The timber construction elements had to fit exactly because of the enormous dimensions of the 150-meter-long hall.
The project
Since 2016, the A16, the Transjurane, has connected the Swiss highway network with that of France. For the maintenance of the southern section of the Transjurane, a large depot was built near Loveresse, replacing several depots.
The workshop was built as a wooden structure in accordance with the energy-saving Minergie-P-Eco standard. Practically only wood from Switzerland was used.
The construction
The supporting structure above ground consists of a skeleton construction lined with timber frame elements. Glulam columns and purlins are arranged in three longitudinal axes. Ribbed beams run above them in the direction of the shorter building dimension. Horizontal stabilization is provided by planked framed walls that have been arranged in selected bays between the columns.
The challenge
The dimensions of the structure required extremely precise planning to accommodate any tolerances. Even slight inaccuracies can add up to deviations of several centimeters over a length of 150 meters. The timber construction elements, which were manufactured with millimeter precision, therefore had to fit exactly onto the prepared concrete foundations. Timbatec planned the filler elements in such a way that construction tolerances are accommodated in these elements between the main supports.

The Werkhof of the A16 motorwa, Loveresse
Diversity in timber construction, The most beautiful pages of the Canton of Berne, August 2019 - With the publication series "The most beautiful pages of the Canton of Berne", the Building Insurance Berne pays tribute to the diversity of buildings and landscapes in the canton in words and pictures. Each publication is dedicated to a different theme. In the current edition of the publication series "The most beautiful pages of the Canton of Berne", everything revolves around the theme "Diversity in timber construction". The freeway workshop in Loveresse was praised as particularly successful.
3rd rank of the West Region for the Werkhof Loveresse project
Theme booklet of Hochparterre, October 2018, 10/2018 - The operation centre near Loveresse is awarded the 3rd place Holzpreis Schweiz - Prix Lignum 2018 of the region West. Since 2016 the A16, Transjurane, connects the Swiss motorway network with that of France. For the maintenance of the southern section of the Transjurane, a large factory yard was built near Loveresse, which replaces several of the yards. The yard was built as a timber construction in accordance with the energy-saving Minergie-P-Eco standard. Virtually only wood from Switzerland was used. The supporting structure over the terrain consists of a skeleton structure inlaid with wooden frame elements. Supports and purlins made of glulam are arranged along three longitudinal axes. Ribbed beams run above them in the direction of the shorter building dimensions. Picture © Hochparterre
Constructive beauty
First 4.17 - The Swiss trade magazine First dedicates ten pages to the Werkhof in Loveresse, where Timbatec was responsible for timber construction and fire protection planning. The theme of the issue is "Models - timber construction in public space" and is dedicated to the models of the editorial staff in matters of public timber buildings. The most prominent presentation is the "functionally beautiful Werkhof in Loveresse", according to the editorial of the issue. The magazine not only describes the wooden construction in the Bernese Jura in great detail, but it has also been illustrated in detail in many photos, some of them double-sided. The article also highlights an important advantage of wood as a building material: sustainability. Almost all of the timber used at the Werkhof - 1235 cubic meters - has grown in Swiss forests; all of Loveresse's construction timber grows back in just five hours.
