About The Project
Topographic survey & invert investigation of manholes around the John St. bridge in Hamilton, on Metrolinx’s Grimsby corridor. A list of manholes and catchbasins were provided to Groma for investigation to confirm their locations and pipe measurements.
Some manholes were not located due to being buried under granular material.
The client received all field data and photos taken from site, with all invert measurements.
