Objective(s): To conduct geotechnical investigations including drilling of boreholes, sampling and analysis of granular material collected, and installation of thermistor (temperature) cables. The geotechnical investigations are conducted to support design and construction planning of the Inuvik to Tuktoyaktuk Highway.

Project Description: The Government of the Northwest Territories – Department of Transportation (DOT) proposes to conduct geotechnical investigations in the winters of 2013 and 2014. Geotechnical investigations will include drilling of boreholes, sampling and analysis of granular material collected, and installation of thermistor (temperature) cables. The geotechnical investigations are conducted to support design and construction planning of the Inuvik to Tuktoyaktuk Highway. DOT proposes to: • confirm the volume, quality and extent of material (“prove” material) at borrow sources 177 South, 309 and 174); • investigate up to 14 prospective borrow sources over a two year period to explore for, and if suitable, “prove” supplemental borrow material sources that could be used during construction or operation of the ITH; and • conduct geotechnical investigations at bridge crossing locations and at selected upland sites along the alignment in order to support detailed, final design of the highway. The 2013-2014 Geotechnical Investigation Program (the Program) will consist of: • drilling up to 500 boreholes at up to 17 borrow sources; • drilling up to 30 boreholes at 13 bridge crossings along the ITH alignment; • drilling up to 18 boreholes at 6 specific upland locations along the ITH alignment to support detailed embankment design; • constructing approximately 217 km of access trail; • mobilizing, setting up, operating, dismantling and demobilizing a single 28-person, mobile sleigh camp to each of four camp locations during Year 1 (2013) and Year 2 (2014); • mobilizing, operating and demobilizing an 8-person mobile survival camp; and • obtaining representative samples from each borehole for further analysis This Program will occur March – mid April 2013, and January – February 2014, and will take 35 to 45 days to complete each year. A summary of this Program’s findings will be provided to the Aurora Research Institute. The fieldwork for this study will be conducted from March 1, 2013 to April 15, 2013.
