Thanks to recent advances in artificial intelligence (AI), civil engineers can inspect large-scale infrastructure more efficiently and cost-effectively, while also monitoring the progression of damage severity over time. A team of researchers has demonstrated the feasibility of an AI-driven method for crack detection, growth and monitoring, and will soon test it on the railway section between Zermatt and Brig in Valais Canton.

McGill study suggests a '30-minute city' is more attainable, though would still require urban design changes In the "15-minute city," a concept popularized in Europe, everything a resident might need on a daily basis is a short walk or bicycle ride away. A study by Transportation Research at McGill University (TRAM) suggests, however, that this model may not be easily achieved in large North American cities such as Montreal.

Researchers from ETH Zurich and the Eastern Switzerland University of Applied Sciences have developed a novel solution for heat pumps. Using this new approach, companies can generate carbon-free process heat at temperatures of up to 200 degrees Celsius while also drastically reducing the number of different heat pumps required.

New evidence of one of the first cities in the Pacific shows they were established much earlier than previously thought, according to new research from The Australian National University (ANU). The study used aerial laser scanning to map archaeological sites on the island of Tongatapu in Tonga. Lead author, PhD scholar Phillip Parton, said the new timeline also indicates that urbanisation in the Pacific was an indigenous innovation that developed before Western influence.

A new material developed at EPFL could change how we make cement forever - and cut 500 million tons of emissions by 2030.

After extensive analyses, researchers found the cause of the concrete scandal in County Donegal, Ireland, where structural damage has been causing red faces and protests for years: Concrete walls of thousands of houses are riddled with cracks, necessitating expensive repairs or even demolition. For the longest time, an excessively high mica content in the concrete was thought to be the reason.

To be more sustainable, the construction industry needs reliable service-life predictions for structures. Ueli Angst calls for a paradigm shift in forecasting the durability of reinforced concrete. The construction industry is experiencing a revolution, with digitisation, decarbonisation and robotics-assisted fabrication all having a lasting impact on practice and research.

In his PhD thesis, EPFL researcher Martí Bosch proposes a method for spatially quantifying the impact of mitigation measures - planting green spaces and using different building materials - on the urban heat island effect. During hot weather, cities are warmer than the surrounding rural areas. This well-known phenomenon - known as the urban heat island effect - is particularly acute at night when concrete and asphalt release the heat stored up during the day.

People living in housing built in the last 10 years were more likely to report feeling uncomfortable in their home during lockdown, while those in pre-1919 developments were most likely to be comfortable, according to a new report led by UCL researchers. The research team surveyed 2,500 households across the UK to find out how the design of their homes and neighbourhoods affected their experience of lockdown.

By Christoph Pelzl Under the scientific direction of Graz University of Technology, an Austrian consortium is working on new investigation methods for rapid and precise assessments of concrete structures. Additional at the end of the text Whether crumbling tunnel walls, cracks in concrete facades or porous bridge piers, according to statistics from the National Association of Corrosion Engineers (NACE), damage to concrete structures caused by various environmental influences accounts for several billion euros worldwide every year.

A world premiere in Austria: The new bridge construction technology which was developed at TU Wien has now been successfully applied by ASFINAG during the construction of the Fürstenfeld Motorway There are many different methods for erecting bridges - but the new technique developed by TU Wien, the balanced lowering method, is quite spectacular: the bridge is not built horizontally, as would normally be case, but erected in a vertical position and then rotated into the horizontal position.

Channels McGill University News and Events New research from McGill University and the University of California, Santa Cruz has found that the local streets of the world's cities are becoming less connected, a global trend that is driving urban sprawl and discouraging the use of public transportation.

Researchers at EPFL have developed a method that uses artificial intelligence to design next-generation heat-pump compressors. Their method can cut the pumps' power requirement by around 25%. In Switzerland, 50-60% of new homes are equipped with heat pumps. These systems draw in thermal energy from the surrounding environment - such as from the ground, air, or a nearby lake or river - and turn it into heat for buildings.

Cities which have a balance between facilities, housing and natural green spaces have lower levels of socio-economic inequality in the life satisfaction of its residents, according to new research. ‌ In a European-wide study, led by the University of Glasgow MRC/CSO Social & Public Health Sciences Unit and published today in Social Science & Medicine, scientists found links between urban design and levels of inequality in life satisfaction.

Children living in greener urban neighbourhoods may have better spatial working memory, according to new research by UCL Institute of Education (IOE). Spatial working memory is a measure of how effective people are at orientation and recording information about their environment. It enables us to navigate through a city or remember the position of objects and is strongly inter-related with attentional control.

The first railroad bridge in Germany made of ultra-high performance concrete (UHPC) has gone into operation on Bavaria's Tegernsee-Bahn railroad route near Gmund. The innovative high-performance concrete made it possible to build a particularly thin bridge. Engineers from the Technical University of Munich (TUM) planned the project and provided scientific supervision.

Steel bridges cost a lot of money to build. It's been estimated that the new motorway viaduct near Oberthulba in Bavaria will cost around 85 million Euros. Planners know that in order to save on material costs, build components should be designed with as much openwork as possible, whilst maintaining stability.

Exposure to household air pollution from using wood or coal for cooking and heating is associated with higher risk of death from heart attack and stroke, according to new research published in the Journal of the American Medical Association (JAMA). Around three billion people worldwide use solid fuels (e.g.

Research news In the summer of 2017, researchers from the Technical University of Munich (TUM) pushed the old Saale bridge in Hammelburg in Franconia to its limits: They carried out a total of five load tests - resulting in nasty cracks. In combination with laboratory tests, they hope to determine whether older bridges have greater load reserves than previously assumed.

The arrangement of a city's streets and buildings plays a crucial role in the local urban heat island effect, which causes cities to be hotter than their surroundings, researchers have found. The new finding could provide city planners and officials with new ways to influence those effects. Some cities, such as New York and Chicago, are laid out on a precise grid, like the atoms in a crystal, while others such as Boston or London are arranged more chaotically, like the disordered atoms in a liquid or glass.
