Exterior Wall Repairs for University Residence
Exterior Wall Repairs for University Residence, Ryerson University, Morrison Hershfield
The Pitman Hall Residence, located in Toronto, ON, is an occupied 14-storey residence for Ryerson University.  The building was experiencing deteriorated masonry units and mortar joints, poor condition of exterior sealants, and movement, cracking, staining, corrosion, spalling and water leakage in several of the upper storey units.

Prior to retaining Morrison Hershfield, another firm recommended re-cladding the entire building by replacing all masonry units, with estimated repairs of several million dollars.  Due to limited funding, the University determined verification of the initial proposed work.

Morrison Hershfield investigated the cause of the deterioration and water leakage and implemented repairs to restore the cladding.  Following visual review and other measures, it was found that the exterior walls could be retrofitted rather than completely re-clad and that small roof areas could be replaced.  Repairs were formulated that addressed all requirements without requiring complete replacement of the exterior masonry cladding.

As this building is partially occupied during summer months, the repairs had to be implemented with minimal disruption to the occupants.  Occupant disturbance was minimized, and the integrity of the exterior masonry veneer and the building envelope was fully stabilized at a substantial cost savings to the client.  The recommended repairs have an estimated budgetary savings in excess of $1 million.
