ST. LOUIS, Mo. — The Associated General Contractors of Missouri recently presented The 2015 Keystone Award for Project of the Year award to IWR Building Systems for its work on the Shriners Hospitals for Children in St. Louis. The annual awards, divided into 12 categories, recognize contractors’ successes in resolving construction challenges faced on a project. IWR won in the specialty subcontractor category for projects in the $2-5M range for its complete responsibility of the Shriners Hospitals for Children’s building enclosure.
The building exterior consists of 3,600 rotated square aluminum composite material metal panels that required precise craftsmanship due to the intricate geometric details of the building surface. The panel system has been engineered with a pressure-equalized rainscreen design, which allows for a drainage cavity behind the panels. To reassure the building owner that the enclosure will function properly, IWR became the only exterior contractor in St. Louis to be certified by the Air Barrier Association of America as a requirement to having a weather-resistant barrier installed.
The other 2015 Keystone Award winners include Musick Construction Co., Tarlton Corp., McCarthy Building Companies Inc., Bloomsdale Excavating Co. Inc., Goodwin Brothers Construction, Golterman & Sabo Inc., Guarantee Electrical Co., Icon Mechanical Construction & Engineering, Murphy Co. and Herzog Contracting Corp.
