ALBERTA TRANSPORTATION NORTH CENTRAL REGION – ATHABASCA AREA INSTRUMENTATION MONITORING RESULTS FALL 2017 SECTION C SITE NC017A-1: HWY 63:12 TWINNING PROJECT BETWEEN SW18-90-9-W4M AND NW31-90-9-W4M ON HWY 63 NEAR FORT McMURRAY 1. OBSERVATIONS 1.1 Field Program and Instrumentation Status One slope inclinometer (SI99-2) was read at the Highway 63:12 site on September 17, 2017 by Mr. Aldrin Pascua of Thurber Engineering Ltd. The SI was read using a RST probe with a 2 ft. wheelbase and a RST hand-held readout. Inclinometer reading depths were defined as per cable markings with respect to the top of the inclinometer cable clamps. 2. INTERPRETATION 2.1 General SI plots A and B directions are presented in Section D and are summarized below. Where movement has been recorded the resultant plot (X direction) and rate of movement have also been provided. 2.2 Zones of Movement Zones of new movement were not observed since the last set of readings in the spring of 2017. Zones of movement are summarized in Table NC017A-1-1 at the end of this report. Table NC017A-1-1 also provides a historical account of the total movement that has occurred at this site since the initialization of the slope inclinometers, the depth of movement and the maximum rate of movement that has occurred since the initialization of the SIs. 4127 Roper Road, Edmonton, AB T6B 3S5 T: 780 438 1460 F: 780 437 7125 thurber .ca
2.3 Interpretation of Monitoring Results Slope inclinometer SI99-2 has shown a rate of movement of 3.0 mm/yr over 20.9 to 22.8 m depth since the spring of 2017 reading. 3. RECOMMENDATIONS 3.1 Future Work SI99-2 should be read again in the spring of 2018. 3.2 Instrumentation Repairs No repairs are required at this time.
