Construction sites are dangerous places. Heavy steel beams, concrete pillars and cement blocks, bricks and rebar, all capable of inflicting injury or damage to their surroundings. Add height when working on a highrise, these items can be exponentially more treacherous.
And then, you have the Chicago Riverwalk.
Take all that steel, concrete, and iron, and add water. All around. Stop by the Chicago River on a typical working day, and you’ll find one crews using one accessory not normally seen on a construction site: life vests. They’re a constant reminder crews on cranes, barges, and platforms are surrounded by water.
