This meant that the safety of the public had to be ensured through clear demarcations and the protection of busy areas, all within a limited construction site area. This also required extensive technical installations to serve Migros and […]

The constraints of the site are taken into account in the project, which makes the most of the available surface area. The volume is defined both by the orthogonal grid of urban planning in La Chaux-de-Fonds and by the existing context. The plan is thus defined by communal alignments, and the elevation adapts to the neighboring building occupied by the Cantonal Tax Office […]

Four three-storey apartment blocks have been built on a long, slender site with a height difference of more than ten meters. The project is suspended on the slope. It is characterized by a succession of terraces that take in the near and distant landscape. These open up the spaces to the view and protect them from surrounding nuisances. The unity of the whole is ensured by […]

Planning and construction of a tunnel system with a total length of 5.8 kilometres and seven underground structures Since 2014, the Hamburg research facility has been used to generate extremely intense X-ray flashes for use by researchers all over the world. The flashes are produced in a 3.4-kilometre-long tunnel which is mostly underground. They can be used to map atomic […]

The project included blasting of tunnels, caverns and concrete works, including inlet tunnels, outlets in the sea, shafts, tunnel portals and extensive concrete works inside the power station. The station itself is located 1.5 km inside the mountain and 15 meters below sea level. Tunneling was done using traditional drilling and blasting. The three longest hatch shafts of […]
