The Golder Fellowship Program Golder Associates (Canada) has committed $500,000 over five years to initiate two exciting new collaborative research programs in the GeoEngineering Centre. The first involves support for three faculty members in Civil Engineering and Geological Engineering at Queen’s University. Each Golder Fellow will receive $20,000 over the calendar year to strengthen collaborative research and graduate straining with technical experts from Golder Associates. Richard Brachman, Professor and Golder Fellow, is working with MASc student Ryan Waud and Frank Barone, Principal of Golder Associates (Mississauga) on the project `Field-scale monitoring of geosynthetic liners during construction`. This project involves work by to measure displacements on a landfill side slope along gravel/ geotextile/geomembrane interfaces during construction and waste placement, to evaluate local downslope shear induced indentations, and to quantify the effects of sand cover placement method on the fate of wrinkles in HDPE geomembranes for landfill base liners. The work will provide new insight into how shortterm construction issues may impact long-term performance of geosynthetics used in landfills. Ryan Waud undertaking field work in Barrie with Golder Associates in 2013. Andy Take, Associate Professor and Golder Fellow, is working with MASc student Lisa Wheeler and Senior Geotechnical Engineer Graeme Skinner of Golder in Mississauga on the project ‘Optimization of mass stabilisation of peat rail subgrades’ is using novel techniques employing multiple high-speed digital cameras to isolate ground vibration from optical measurements of rail and sleeper movements under railways. The project will develop new methods of measuring longitudinal and vertical rail displacements at full track speed and provide new insights into track support mechanisms. 2 Heather Jamieson, Professor and Golder Fellow, is leading the project ‘Speciation of arsenic in lake sediments near Giant Mine, Yellowknife, NWT’ in collaboration with Arthur Cole, Principal of Golder Associates in Edmonton and Hilary Machtans, Senior Fisheries Biologist in Whitehorse. This project with MSc student Martin Van Den Berghe involves installing field instrumentation and taking field samples of sediments in three lakes west of the former Giant gold mine and ore roaster. The project will provide new insights into the origin, age, bioavailability and long-term stability of arsenic present in the lake sediments. Martin Van Den Berghe taking sediment samples in the field 2. The Golder Visitor Program The second new initiative is the Golder Associates Visitors program. Each year, this program will fund four extended visits to Kingston by international scholars and experts from different technical communities within Golder Associates. Visits will last from one to three months, and permit collaborative research, delivery of seminars and short courses, and productive interactions linking the visitors to geoengineering faculty members and students, as well as other technical experts from Golder Associates. The program initiates early in 2014 with a visit from Dr Vassilis Marinos, from the Aristotle University of Thessaloniki in Greece. Dr Marinos will collaborate with faculty members from Geological Sciences and Geological Engineering at Queen’s and Civil Engineering at RMC, delivering lectures at Queen’s as well as a webinar at Golder Associates in Mississauga. 3 9th Victor Milligan lecture On October 9, 2013, Professor Michele Jamiolkowski delivered the Ninth Victor Milligan Lecture. Dr. Jamiolkowski began his academic career in 1969 at the Department of Geotechnical Engineering, University of Torino, Italy where he is currently Professor Emeritus. He is author of over 200 publications and reports and holds many prestigious awards, including the De Beer Award from the Belgium Geotechnical Association, the Karl Terzaghi and Ralph B. Peck Lecture Awards from the ASCE, and the Italian “Saviour of the Art” Award. Dr Jamiolkowski served as President of the ISSMFE (1994 1997) as well as the International Committee for Safeguarding the Leaning Tower of Pisa (1990 - 2001). Funding for the Victor Milligan Lecture is provided by Golder Associates, in memory of the late Victor Milligan, one of the founders of the company, the first Editor of the Canadian Geotechnical Journal, and a Terzaghi Lecturer for the American Society for Civil Engineering. Professor Jamiolkowski’s Milligan Lecture “Soil Mechanics and the Observational Method: Challenges at the Zelazny Most Copper Tailings Disposal Facility” was the 53rd Rankine Lecture prepared for the British Geotechnical Association and presented on March 20, 2013. Awards and honours Queen’s University professor Kerry Rowe Civil Engineering and GeoEngineering Centre at Queen’s-RMC has been elected a Fellow of the Royal Society in the United Kingdom. Dr. Rowe is one of only four Canadians, and the world’s only civil engineer, elected to the prestigious institution in 2013. Kerry was also awarded the Queen`s University Prize for Excellence in Research, and was also the recipient of the Queen’s award for graduate student supervision. Dr. Richard J. Bathurst began his 2013-2014 term as President of the Canadian Geotechnical Society. He was also awarded the 2014 Giroud Lecture by the International Geosynthetics Society which will be delivered at the opening session of the 10th International Geosynthetics Conference to be held in Berlin in 2014. 4 Professor Jean-Louis Briaud, President of the International Society for Soil Mechanics and Geotechnical Engineering has announced that Dr. Greg Siemens has been selected as one of just three recipients of the ISSMGE Young Member Award. In announcing the award, Dr. Briaud indicated that Greg was selected after an international competition of some of the best that this world has to offer. This international recognition in GeoEngineering is awarded to up to three young members in recognition of outstanding contributions to the development of geotechnical engineering through scientific and technological work. The award will be made in Paris at the occasion of the 18th International Conference on Soil Mechanics and Geotechnical Engineering. NSERC has announced the award of a Discovery Accelerator Supplement to Dr. R.J. Bathurst who is a member of the GeoEngineering Centre. He joins Drs. Jean Hutchinson and Kerry Rowe who received the same award last year. These highly competitive awards, are given to about 1 in 25 discovery grant award holders nationally and are awarded to proposals that suggest high-risk, novel or potentially transformative research that could contribute to groundbreaking advances in the area of study. The GeoEngineering team has been exceptionally successful receiving these funds since the accelerator supplement program was initiated six years ago. A total of seven of these awards have been made to our sixteen team members, a success rate that is almost ten times the national average. Kevin Mumford has received funding to support three new projects. A Strategic Research Grant from NSERC was awarded for study of contamination of river beds by oil spills (with four other researchers including Principal Investigator Ana da Silva). Work is underway combining electrokinetics and electrical resistance to heat the ground and produce groundwater remediation (work funded by Geosyntec Consultants, Inc.). Finally, funding from the American Petroleum Institute is supporting work on in situ remediation of hydrocarbons in the subsurface, work with six other researchers including Principal Investigator Neil Thomson of the University of Waterloo. 5 The Engineering Institute of Canada has awarded the John B. Stirling Medal to Dr. Ian Moore. In its press release, the Institute indicates that this is one of five senior awards of the EIC that recognize “outstanding achievement or service to the engineering profession". In particular, the Stirling medal is "for leadership and distinguished service at the national level within the Institute and/or its Member Societies". It recognizes Ian’s contributions to the national society through editorship of the Canadian Foundation Engineering Manual published in 2006, his term as Vice-President Technical of the Canadian Geotechnical Society in 2003 and 2004, and his contribution as founding chair of the Kingston Chapter of the Canadian Geotechnical Society. CGS recognizes GeoEngineering Centre Members and students at GeoMontreal Several members of the GeoEngineering Centre and their students were recognized at CGS events held in conjunction with GeoMontreal, the 66th annual conference of the Canadian Geotechnical Society.

Early progress includes identifying small rockfalls around the perimeter of a larger, subsequent failure which impacted the railway, and potentially measuring bulk movements of the block prior to rapid failure. Rockfall modelling in three dimensions, using terrain and rockfall observations from terrestrial LiDAR: M.Sc. student Matthew Ondercin is using detailed terrestrial LiDAR-based terrain data of a complex slope, and rockfall source locations and trajectories measured there, as inputs for both traditional GIS rockfall modelling, and in a novel, true 3D approach that he is developing. Early progress includes the ability to model the performance of railway track protection measures based on cumulative rockfall deposition. 10 Containing Diesel Contaminated Soil in Antarctica Using Geosynthetics Daniel Jones (PhD Candidate),Supervisor: Kerry Rowe. During the Antarctic summers of 2012-13 and 2013-14, Dan Jones travelled to Casey Station, Antarctica to assist with the onsite remediation of 800m3 of diesel contaminated soil. Despite the use of best practices for fuel handling, spills can and do continue to occur. Seven geomembrane and GCL-lined biopiles were constructed from 2011-2013 to remediate the soil on site; this is the first time geosynthetics have been used on the continent. Geosynthetics were the ideal choice for containment given the lack of low permeability soil in the area. Testing of new geomembrane materials was also conducted, with one biopile being lined with a coextruded HDPE/EVOH/HDPE geomembrane which has never before been used in full scale field trials. It was unknown how well geosynthetics would perform in the harsh Antarctic climate. The continent is prone to extreme temperature fluctuations, high UV during the summer and generally very dry and arid conditions. This environment can accelerate the degradation of geomembranes as well create a very difficult task for GCLs up taking moisture. Some of Dan’s specific tasks included sampling of geomembrane sundeck experiments, where samples are placed on rooftops to allow maximum sun exposure and destructively sampled yearly. Dan also conducted GCL hydration testing in the field, which will be mimicked in the laboratory at Queen’s, allowing the GCLs to hydrate at field conditions to be compared to expected saturation. Financial and inkind funding for Dan’s work was provided by the Australian Antarctic Division AAD.

Canada's water infrastructure is reaching a point where safe and efficient operation cannot be guaranteed without a better understanding of the failure mechanisms associated with corroded pipes, and guidance on assessment and repair strategies. In September 2013, the Natural Sciences and Engineering Research Council of Canada granted $571,950 over three years to Dr Ian Moore and Dr Neil Hoult to study remaining strength and pipe repair issues in both cast iron water pipes and corrugated steel sewers and culverts. The Water: Management and Assessment of Infrastructure (WaterMAIN) project will address key issues by investigating (a) the remaining strength of buried deteriorated cast iron and corrugated steel pipes after they are damaged by corrosion, (b) the impact of soil erosion adjacent to pipes due to water flow, (c) novel methods of identifying, monitoring and assessing these structures, and (d) the short and long term performance of repair techniques. The research project capitalizes on specialised infrastructure for conducting buried pipe experiments at Queen's, permitting unique experiments at full scale that will provide seminal data on pipe behaviour and the performance of assessment tools, and will produce significant advances in numerical modeling of deteriorated structures and the soil surrounding them. Both the existing test facilities at Queen’s and new capabilities being developed to simulate soil erosion around deeply buried pipes will be utilized. The project will advance scholarship on the interaction of soil and deteriorated pipe structures, and the development and impact of the erosion voids beside pipes. Industry partners Michael Maher (Golder Associates), Kevin Bainbridge (Robinson Consultants Inc.), Ian Doherty (Trenchless Design Engineering Ltd.) and Mike Zantingh (City of Hamilton) are providing in-kind support of various kinds. Work will include development of a module on sewers and culverts for program GoldSET. This software is a tool developed by Golder Associates for characterising the environmental, social, economic and technical challenges during infrastructure project planning and design.

Figure 2: Surface live loading of the deteriorated culvert using the MTS Servo=controlled testing system in the GeoEngineering Laboratory. 12 NCHRP 20-07 Task 316: Guidelines for use of Design Methods for Reinforced Concrete Pipe Katrina MacDougall supervised by Ian Moore and Neil Hoult Buried concrete pipes are designed using two different procedures in North America. The first, Indirect Design, is a simplified approach that uses an empirical ‘bedding factor’ to relate strength when buried to the strength during ‘pipe-only’ testing. The second, Direct Design, features estimates of moment, thrust and shear around the pipe circumference and the use of conventional reinforced concrete design approaches to determine steel amounts. This project sought to determine whether Indirect and Direct Design procedures are consistently conservative, and to explain and potentially reconcile discrepancies between the two methods. Firstly, two 0.6 m diameter pipes and two 1.2 m diameter pipes were tested under single wheel pair loading at burial depths of 1.2, 0.6, and 0.3 m. The test pipes did not crack at the applied service load of 110 kN and did not exceed the crack width limit of 0.25mm until between 2.5 and 4 times the service load. One 0.6 m diameter pipe was also tested under simulated deep burial and was found to have cracking load almost 2 times greater than the calculated value. Both methods provided conservative strength estimates for the test pipes. An investigation of the Direct Design procedure found that by considering thick ring theory and the Modified Compression Field Theory with two layers of reinforcement, the required amount of steel from Direct Design could be made to align very closely with Indirect Design. Additional tests were performed to measure radial earth pressures on a shallow buried 0.6m diameter test pipe using the ‘null’ sensors of Talesnick. These pressures indicate that lateral soil stresses acting on the pipe springline are much lower than those that arise from use of standard pressure distributions. This project was funded by the National Cooperative Highway Research Program of the Transportation Research Board (National Academy of Sciences, Washington D.C.) as Project 20-07 Task 316. The project was directed by a panel of highway and other engineers with the specific goal of suggesting changes to the LRFD (Load and Resistance Factor Design) Bridge Design Specifications of the American Association of State Highway and Transportation Officials.
