Nature of Work: Construct the region’s first indoor rock-climbing facility
Location: Quechee, Vermont
Trumbull-Nelson Construction completed the area’s first facility exclusively built as a rock-climbing gymnasium.
During the design phase of the design-build project, to achieve the necessary 43-foot clearance for the climbing walls, T-N sunk the gym floor 5-feet below grade to allow for the necessary interior height yet stay within the 40-foot maximum exterior building height requirement.
The exterior walls, as viewed from the road, are wood and typical of a New England barn structure. The building encompasses intricate valley design and true cold roof over bar joist construction with 100% venting to minimize the influence of ice damming. Two of the walls utilize a Butler steel wall system. The imprint wall, shown at right, was built on a steel rod truss assembly with a cementicious coating to resemble natural rock. The other walls are crystal plywood on a wood truss structure.
Due to the nature of the climbing wall’s attachment to the building, engineering requirements were significant. The process began with the assumption that the wall would hold six climbers at the same time, and that all would fall on the belay line at the same time. The need for the wall to hold horizontal reactions during such an incident influenced engineering and design conditions.
