Historic Building Process

Condominium structures are built by property developers and in most urban settings the parking garage is generally underground. Developers have a two-year obligation to the Condominium Corporation covering non-structural and non-life safety components of the building. This includes waterproofing structural elements in the parking garage and elsewhere. The short warranty period incentivizes some developers to install the minimum protection required by the building code. The current code only requires that elevated slabs be protected by an elastomeric membrane and traffic bearing surface. It does not require that the Architect or Designer of structural protection systems design for durability. This lack of guidance in the building code will be changed significantly with the new iteration of CSA S413:21, due to be released later in 2021. The new code will require that deck membrane systems be designed to receive four distinct levels of…
