Three Hills, Canada
Golden Hills School Division #75
Building Envelope Consultant
About 500 students, ranging from kindergarten to grade 12, currently attend Alberta’s Three Hills Public School. Originally built in the 1960’s, a 2002 addition provided extra classroom space and linked the two original buildings. Due to construction errors, the cladding on the school was replaced in 2004, yet the school continued to experience moisture penetration and visible cladding deterioration.
Golden Hills School Division #75 retained Entuitive to provide a detailed investigation of the school, including visual review, moisture measurements and exploratory openings. Entuitive analyzed the extent of the existing failures, identified the mode of these failures, and recommended several remedial works, including: recladding Three Hills School with an appropriate exterior cladding assembly and revised tie-in details where the exterior walls connect to the roof assemblies and windows.
Challenge: Entuitive had to determine how much of the wall to take down and find a versatile cladding system that would provide a consistent look to the envelope.
Solution: Since brick is expansive in Alberta, Entuitive chose a Miami-Dade County-rated hurricane EIFF cladding, which stands up to the rigours of schoolchildren at play. We also minimized the amount of cladding that had to be removed, thus minimizing labour expenses.
