The Werkhof of the A16 motorway, Loveresse BE
2017
Highest precision was required at the Werkhof of the A16 motorway in Loveresse in the Bernese Jura. Due to the enormous mass of the 150 meter long hall, the timber construction elements had to fit exactly.
The Project
Since 2016, the A16, the Transjurane, has connected the Swiss motorway network with that of France. For the maintenance of the southern section of the Transjurane, a large work yard near Loveresse was built, which replaces several work yards.
The Construction
The Werkhof was built as a timber structure to the energy-saving Minergie-P-Eco standard. Practically only timber from Switzerland was used. The supporting structure above the ground consists of a skeleton construction lined with timber frame elements. Supports and purlins made of glulam are arranged in three longitudinal axes. Above this, ribbed girders run in the direction of the shorter building dimensions. The horizontal stabilization is achieved by planked frame walls, which have been arranged between the columns in selected fields.
The Challenge
The Werkhof is 150 meters long and 30 meters wide. The dimensions of the building required extremely precise planning in order to compensate for any tolerances. Even slight inaccuracies can add up to deviations of several centimeters over a length of 150 meters. The timber construction elements, manufactured to the millimeter, therefore had to fit exactly onto the prepared concrete foundations. Timbatec designed the panels to accommodate construction tolerances in these elements between the main columns.
In the area of the salt storage hall, the timber supports in the hall walls had to fit into recesses with very little clearance. The recesses were measured with a tachymeter and the formwork was checked before concreting.

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.
