No road- or transit-user impact from geotech works: Metrolinx

Metrolinx, the operator of GO Transit, says there is no anticipated impact on road or transit users from the scheduled geotechnical investigative works at Whitby.

As part of investigative work for the GO Expansion project, crews will be drilling vertical boreholes to assess ground conditions within the Lakeshore East rail corridor. This work will support future track and infrastructure updates.

Drilling was scheduled to take place Monday – Sunday beginning January 15. Work will move within the area highlighted on the map (above) for approximately two months. Borehole drilling is sequenced and moves throughout the rail corridor as work progresses, said a Metrolix statement.

It said crews will use a drill rig to perform the investigation works. The drill is rotated and pushed into the ground by the drill head. Once the desired depth is reached, a soil sample is retrieved for analysis.

In advance of borehole drilling, crews are required to identify underground utilities and clear a path at certain borehole locations to move a drill rig within the corridor. This may involve routine maintenance and removal of small shrubs and other low-lying vegetation.

A vac-truck may be used at certain borehole locations to identify utilities in advance of drilling. Residents may experience some noise and minor vibration from the drill and other construction vehicles or equipment. Noise and vibration monitoring will take place and mitigation measures will be applied as required.

Work will take place within the rail corridor. Site lighting will be pointed away from residences.

There are no anticipated traffic, pedestrian or transit impacts from the works, said Metrolinx.
