Bridge structures, which account for a large proportion of high-speed railways and urban rail transits, produce vibration that radiate low-frequency structural noise. This low-frequency noise can affect people’s physical and mental health, as well as affect ancient buildings along the line; the manufacture of precision instruments and equipment; and the use of high-precision laboratories.

Researchers have developed a new material that shows great promise as a means of removing copper — which is linked to disease and organ failure — from contaminated water sources.
In the high-risk industries of civil engineering and construction, workers are often exposed to serious hazards. According to OSHA, one in five worker deaths in 2018 were in construction. The leading causes are a result of the “Fatal Four” – falling, being struck by objects, electrocution, and caught-in-between hazards.
