Engineering structures such as bridges are exposed to high loads. In addition to the aging processes of the material, environmental influences and an increased traffic volume are added. Regular checks of (more…)

The tunneling project of superlatives was originally scheduled to start at the beginning of 2019. Due to the necessary cost savings and the departure of the shipping company Hurtigruten, it is likely that the project will now be scaled down. The planned start of construction will also be postponed to 2022.

Norway's tunnel construction project for ocean-going vessels is delayed

Even the largest cruise liners of the Hurtigruten line will be able to sail the new ship tunnel in Norway. The city’s skipunnel will be the largest ship tunnel in (more…)

As the number of buildings increases, the demands placed on lift technology, which push people and loads to ever-increasing heights, pose challenges for engineers. Because longer elevator shafts and corresponding pitches are also on the wish list of the builders as demands on high speeds and passenger comfort. A challenge that civil engineers worldwide are working on.

Growing nitrogen oxide emissions are a health problem in large cities. The main causes are u.a. Diesel vehicles identified. Driving restrictions for older vehicles are therefore threatened in some cities. But now Erlus AG has unveiled a titanium-coated roof tile that actively removes nitric oxide.

Researchers from the Swiss Federal Laboratories for Materials Testing and Research (Empa) have developed a refractory insulating material from waste paper together with an industrial partner. It is suitable, for example, for wooden construction elements in wooden houses.

Raw materials such as sand and gravel provide the basis for concrete. And they are getting short of the ongoing construction boom. Researchers from four Fraunhofer Institutes want to address the shortage with recycling.

Halftime construction of the Brenner Base Tunnel: Since 2008, Austrians and Italians have been drilling through the Brenner Pass, the longest underground rail link at 64 km to build the world. Ten years after the start of construction, the largest construction lot has now been awarded – for 37 km main tunnel tube. A huge job. In 2028, the gigantic Alpine tunnel is to be completed. The cost: almost 10 billion.
