Sports and Recreation 

IES has a reputation for innovative sports facility design. Our work integrates long-span structures, cantilevered and suspended jogging tracks and corrosion protection for indoor aquatic centers — complexity that calls for detailed vibration analysis and in-depth structural engineering expertise. We take pride in helping create public gathering spaces which establish a sense of place for the unique communities that we live and work within.
