Our U.S. planning & asset management business has seen consistent growth driven by our clients' needs to address challenges stemming from population growth, aging infrastructure, system reliability and resilience concerns, the need to improve operational efficiency, water quality regulations, and the lack of effective tools to leverage large data sets to help guide decision making. Some employees are subject to extreme cold (temperatures below 30 degrees for periods of more than one hour), extreme heat (temperatures above 90 degrees for periods of more than one hour), hazards (electrical currents, working on scaffolding and high places, exposures to chemicals), atmospheric conditions (fumes, odors, dusts, mists, gases, poor ventilation), and oils.
