Regions Hospital Stairway Fire Door by Won-Door
ST. PAUL, MN.— The 90-minute FireGuard accordion door installed at the top of the stairway in the meets a moving challenge as soon as it leaves its pocket.
The door — fabricated by Won-Door Corporation — has to make a fairly sharp turn out of the gate, wind its way around the stairway and head through a series of gradual curves to the receiver on the other end, essentially making a 90-degree turn en route.
"It was a challenge," said the project manager, Rob Hanks. Hanks worked for the Kraus-Anderson Construction Company then under Brent Hall, now CEO of the WLHall Company of Hopkins, MN.
Hanks said the challenge really lay in matching up the measurements exactly so the door would glide smoothly.
"It wasn't a smooth radius. There were three different radius' the door has to follow," Hanks said. "Just the fact that there were multiple radius' involved made it interesting. If there were any issues at all, it was in the door making that quick turn out of the pocket."
The 33'x 10' standard color door was one of two used in the Regions Hospital expansion. This impressive $178 million-dollar project added an 11-story patient tower, a 55,000 square-foot emergency center and a 69,000 square-foot same day surgery area to the hospital known in the area for more than 130 years as a world-class trauma and emergency center. (Regions is a private, non-profit hospital, the only certified Level I Adult and Pediatric Trauma Center in the Twin Cities.)
Architectural Job Captain Jared Schmidt with Ellerbe Becket Inc. of Minneapolis said the door is at the building's "nexus point." "There's plenty going on in the area," Schmidt said. "This is kind of a centerpiece for the entrance of the building with a coffee shop just adjacent and the main entrance just below. We definitely appreciate Won-Door making it possible to keep it open and still meet the code requirements."
Schmidt added that this is the first job he's worked on that involved Won-Door and he's impressed.
Won-Door representatives collaborated with Ellerbe Becket and Kraus-Anderson to fine tune the plan, making certain the radius didn't exceed what was practical and that the structure above and below could support the movement.
"There was this apprehension on our part about whether the door could do what we were asking," Schmidt said. "As far as I know, it's doing its job."
"We were called in from day one by the architect in charge at the time to discuss the large radius opening," said Andy Garner, Won-Door's District Manager for Iowa, Minnesota, Montana, North Dakota, South Dakota and Wisconsin. "The goal was to provide a non-egress communicating stair application to keep the common floors in the new main entrance wide open.
"Of course, the architect knew we were the best solution and with the help of Mike George and his (engineering) staff (at Won-Door) we laid out the radius opening to their satisfaction.
"We had one other opening on the job that was straight-forward in design and function. It was the bonus door!"
Garner said Dave Isakson and his customer service group did a "fantastic job meeting deadlines and facilitating an on-time delivery" for the showcase installation.
