Challenge:

The interior steel structure of the brick tower was deteriorating. The rusting steel was causing cracking, spalling, and displacement of brick masonry over the entire face of the tower. Although repairs were made sporadically in the past, the school was interested in a comprehensive repair of the tower including restoration of the clock and carillon.

Solution:

CBI, working as a structural consultant to Consigli Construction Co, Inc., recommended three options for repair: Option #1 was to repair the tower in kind, which would entail selective repair of cracks and bricks on the building exterior, as well as the replacement of individual pieces of steel on the interior. This was seen as a short term solution that would require future periodic maintenance. Option #2 required a complete removal of all the existing masonry to expose all the steel, repair of the steel, and reinstallation of all new CMU back-up with waterproofing, and a new cavity wall system with new brick. Option #3 involved leaving the existing tower intact, covering the existing masonry with an air barrier/waterproof membrane and then adding new veneer outside with an air space. The School selected Option #2 and proceeded with the construction. The project was completed in 2006 by the design team of MacLeod Consulting, Inc., Bruner/Cott Associates, and Consigli Construction Co., Inc.
