Meeting the demands of an urbanizing world

The percentage of the world’s population living in cities is expected to rise to a staggering 65% by 2025, up from 50% in 2000. As a result, demand for new infrastructure is going up substantially. This includes commercial and residential buildings, industrial sites, energy and transportation infrastructure. At the same time, construction companies must comply with strict environmental and safety regulations while remaining competitive.
