Scope
FPrimeC was hired by an asset management company to perform non-destructive testing for structural Condition Assessment for Underground Structure in Yorkton, Saskatchewan. The structure under investigation was a underground room primarily used as fitness centre. The roof was a One-Way reinforced Concrete Slab supported over concrete beams. Concrete slab showed sign of moderate corrosion and leakage at several locations.
1- Digital Inspection of Parking Structure
Due to the relatively large area and complexity of the parking structure, FPrimeC used the “INSPECT” digital inspection solution which is a comprehensive, cloud-connected software platform that seamlessly integrates into inspection workflow – facilitating data collection in the field and reporting in a fully digital, customizable and collaborative way. This enabled FPrimeC engineers with location-based capturing, in which all visual inspection results can be pinned to their precise location on the structural drawing plans, reducing the inspection and reporting timeline.
2- Condition Assessment for Underground Structure
Non-destructive Testing and Evaluation (NDT/NDE) was used to evaluate the current condition of concrete slab and the beams. Half-Cell Corrosion Potential Mapping (HCP) was used to study the likelihood of active corrosion in concrete beams. The Ultrasonic Pulse Velocity (UPV) was used to evaluate the condition of concrete at the stem of beams. Rebound Hammer test was used to estimate the in-place concrete strength.
Ground Penetrating Radar was used to identify the structural details, such as rebar spacing, and rebar distribution in the concrete slab. Ultrasonic Pulse was used to estimate the thickness of foundation walls.
