Independent inspection — municipal pavement
Pavement quality is proven, not assumed.
Precision surveys of planarity and cracking, at project handover and again eleven months later — after the first winter. A numbered report, sealed by an OIQ member engineer.
The problem
The defect doesn't show up on handover day.
It shows up after the first freeze-thaw cycle — once the holdback is released and the contractual recourse is gone. Without an independent measurement at that exact moment, the municipality has neither the evidence nor the leverage to demand it.
An undetected pavement failure means a job paid for twice — once for construction, once for the fix.
Every reconstruction avoided also spares the asphalt production, trucking, and waste it would have required.
The method
Two surveys, one standard of measurement.
Same instrument, same measurement points, eleven months apart — so the second survey says something defensible about the first.
Baseline survey
Planarity and cracking measured as soon as construction is complete, at geolocated points that will serve as comparison references.
Comparative survey
Same method, same points, after a full winter — the moment when construction defects actually reveal themselves.
Sealed findings
A numbered comparison against contractual thresholds, signed and sealed by an OIQ member engineer.
The threshold
Five millimetres, measured — not estimated.
The criterion applied is the Ville de Montréal's DTNI-3C standard specification — not a house standard.
- ≤ 5 mm Maximum vertical deviation under a 3-metre straightedge, real or simulated from a continuous profile.
- ≤ 3 mm Crack width tolerated at the eleven-month inspection.
- 0 mm Cracking tolerated at handover.
- ±3 mm Joint alignment over a three-metre section.
