The new 335 million dollar, 875,000-square-foot, seven-story, 260-plus private room hospital replaces the former St. John’s Mercy Regional Medical Center demolished in the May 22, 2011, EF-5 tornado. The deadliest tornado in Missouri and the U.S. since 1947 directly hit the hospital.
Our contract with McCarthy Construction Company for the drilled shafts included excavation of 324 drilled shafts up to 48” in diameter and 90’ deep through mostly hard pinnacled limestone. The aggressive schedule required up to 4 drill rigs working in multiple areas.
