OLJC Boreholes

About The Project

Survey of 19 boreholes at Metrolinx’s OLJC site in east Toronto.

Groma’s surveyor was on site with a representative from Thurber, who took us to the location of each borehole for survey.  Boreholes within the Metrolinx rail corridor were accessed using flagman protection, and while here the surveyor tied into control previously set for Groma’s topo survey in the spring.

The client received a CAD drawing and points list of the boreholes with coordinates and elevations.
