Calgary Geotechnical Investigation
2017 – Calgary, Alberta
Client: City of Calgary
Project Scope
The City of Calgary and Thurber Engineering faced a challenge. They needed to obtain the geotechnical information below the McHugh Bluffs for the future expansion of the C-Train system. This terrain is a steeply sloped and environmentally protected area.
Methods and Solution
Tangiers was given the delicate task of building two engineered drilling pads, whereby large tracked drilling systems could be placed on them. The parameters were such that there could be no evidence that this drilling occurred after the investigation was completed. The pads were constructed and the drill systems brought in. The pads were then removed after completion and the construction areas remediated.
Results
Due to the unique design and construction methodology the engineered pads did not disturb the environment and the goal of zero disturbance was met. This was well received by the City of Calgary project managers, Thurber Engineering and most importantly by the citizens who lived nearby during the active phase of the project. The geotechnical data was obtained in an area that would normally be impossible to drill on. The unique engineered pad systems were the key.
