Structural assessment in Quebec City
Structural assessment evaluates the condition of a concrete structure with non-destructive test methods, before a repair, an alteration or a regulatory verification in Quebec City.
Non-destructive test methods
The American Concrete Institute report ACI 228.2R-13 reviews non-destructive test methods for in-place concrete, including visual inspection, stress-wave, magnetic and electrical methods, infrared thermography and ground-penetrating radar.
Parking garages in Quebec
In Quebec, the Building chapter of the Safety Code requires parking garage owners to carry out a visual verification every year and, every five years, to obtain an in-depth verification report from an engineer. Non-destructive surveys can document the condition of the concrete in support of these verifications.
- Before repairing or strengthening a slab
- Before a change of use or an alteration
- When monitoring a parking garage
- After cracks or spalling appear
Working in Quebec City
In Quebec City, the City indicates that it can give a first response to a permit request within 30 to 60 working days. It is therefore wise to plan concrete surveys early in the project, before filing the plans.
Frequently asked questions
Does a structural assessment replace an engineer’s opinion?
No. Non-destructive tests provide data on the condition of the concrete; structural interpretation and recommendations are an engineer’s responsibility, as the Safety Code provides for parking garages, for example.
Which structures can be assessed?
Usually reinforced concrete slabs, walls, columns, beams and parking garages, in commercial, industrial, institutional or residential buildings.
