Integrated Facility Services has begun work on a nearly $10 million renovation project at the Robert A. Young Federal Building in St. Louis. The project is part of a $62 million design-build retroﬁ t of the historic 20-story building led by contractor McCarthy Building Cos. Inc. The 1.05 million-squarefoot building is located within 150 miles of a fault line, a major seismic zone in North America. Due to the location, IFS is relocating, replacing and bracing mechanical systems, variable-air-volume boxes, HVAC ductwork, ﬁ re protection and plumbing to accommodate the new structural steel braces and seismic dampers. The project is scheduled for completion in late 2018.
