A new tunnel formwork system from Pilosio reduces the time needed for assembly. Made from standard components, this can be used for a wide range of geometries.
Doka’s Concremote makes it possible to measure concrete strength on the site and in real time. It uses the weighted maturity method, as developed by de Vree, to provide reliable, standards-compliant information on the strength development of the concrete. This facilitates targeted management of the forming and CIP concreting operations.
The advantage of the method is the measurement take place directly in the concrete element. With well-placed sensors - thermos-couples - the temperature can easily be mea

New technologies are coming to market with regard to driving and supporting tunnels, with drilling and blasting and accompanying shotcreating technologies being widely used worldwide. Drilling and blasting can be a cost-effective method in the right conditions and in this segment Atlas Copco and Sandvik hold major market shares worldwide, although other firms such as Furukawa and Montabert also compete. Shotcreting equipment is widely used following after drilling and blasting, with CIFA broadening its rang
New safety regulations and high traffic volumes require new tunnel construction all across Europe. Mike Woof reports Anew highway tunnel now being built in Austria will boost traffic volumes and safety standards on a key European route. The existing Pfänder Tunnel lies close to Austria's borders with Germany and Switzerland and carries a heavy traffic volume, so a new parallel tunnel is under construction to help spread this load, increasing capacity as well as safety. Stringent tunnel safety standards have
