sheet and highlighted in orange. It will be reported to maintenance crews for repair typically the day it is encountered. This repair is typically provided as soon as possible, from the time the uplift is noted.

Uplifts do not always have a constant depth. If this is the case, the uplift should be measured at the location where the depth is largest.

Work orders are generated by an Operations/Asset Analyst for all Urgent Uplifts encountered during the sidewalk inspections. These uplifts are considered to be serious trip hazards.

4.5.2    Painting Urgent Uplifts

As mentioned in section 4.5.1, any uplift encountered that is greater than or equal to 20mm will be spray painted with orange paint to warn pedestrians of the potential trip hazard and to help maintenance crews locate the uplift when going out to make the repair. For operational reasons, spray paint is to be applied only to the top of the uplifted slab. Do not spray paint the vertical face of the slab. The reason for this is because the MG-Krete or asphalt will not adhere to the surface as well if the vertical face of the uplifted slab is sprayed. Therefore the operator will need to spend extra time removing the paint prior to completing the repair.

Spray the top of the uplifted slab          Do not spray the vertical face of the uplifted slab
