Lorenzo Wrestling Addition at Rec Hall

Penn State University
University Park, PA

Construction consisted of a single story, steel framed addition to the existing Recreation (Rec Hall.) Drilled piers or caissons support the existing structure, so any settlement of the addition would be considered differential in comparison to the existing building. This foundation technology, however, is considered antiquated in this geologic setting. Difficulties encountered with inspection and the high cost and ambiguity associated with rock removal were considered to be significant obstacles. Also, using driven piles adjacent to existing structures presents concerns with vibration induced damage. Therefore, CMT recommended the use of minipile foundations to support the proposed structure.

Recommendations specified that the column loads be supported by deep foundations and the load bearing walls supported by grade-beams structurally tied to the pile caps. Any non-load bearing or frost walls can be supported by conventional continuous wall footing foundations.
