The Blessed Kateri Tekakwitha Parish church had been experiencing water infiltration and ongoing building exterior maintenance issues since construction was completed in 1993. The church is a two-story timber- and steel-framed structure clad in stucco and thin stone veneer, with both steep-slope asphalt-shingle roofs and low-slope asphalt roof areas. The parish retained Hoffmann Architects to perform an investigation into the causes of leaks and deterioration, and to recommend a remedial course of action.
The investigation revealed evidence of water infiltration at the building perimeter, originating at absent flashings and open sealant joints in parapet coping stones. Water was also entering the building at window openings. In addition, the stucco displayed significant cracking and de-lamination, and exterior facing stone was stained by rust in many locations. Problems related to the asphalt shingle roof were also noted.
Hoffmann Architects provided recommendations for repair with opinions of construction costs, produced contract documents for the full scope of recommended work, assisted the church during the bidding and contract negotiation process, and provided construction administration services for a repair program that included a full roof system replacement (low and steep slopes), parapet repair, window sealant replacement, exterior stucco repair and coating, rust stain removal, and other facade repairs to restore building envelope integrity.
