It isn’t uncommon to build a 20-story structure in St. Louis. It is uncommon to END at grade instead of beginning there. KCI did just that, building two concrete shafts to over 200 feet below grade to pump to a new wastewater treatment plant. This unique project offered constructability and scheduling problems, but also included safety challenges involved in deep, vertical construction. All access for construction was from the “top”, with all workers being hoisted to their work elevations via cranes and man baskets, at one point requiring 13 cranes around a single 90-foot diameter shaft.
