Clifton’s founder, Wayne Clifton, generously and consistently encourages personal and professional growth of our staff. This enthusiasm led him to create, Clifton University (UCAL), an internal university to develop skills that enhance our ability as consultants and career opportunities. Currently, the curriculum covers topics such as leadership, business development, and problem solving.
This week 30 colleagues from our offices assembled in Regina to attend Leadership 101 - a 2-day intensive personal development course guided by Hope Learning that improves our ability to understand ourselves and motivate others to work in teams to overcome challenges. The students were introduced to the science and art of leadership, teamwork and collaboration skills, influence, self-management, and conflict management.

Craig Clifton, VP Alberta, is the Alberta Chamber of Resources' Transportation Committee chair. Working with the Construction Owners Association of Alberta and the Consulting Engineering of Alberta, the committee approached Alberta Transportation with a case for transporting heavier, more complete modules on a three-file trailer.
Results from a successful pilot move from Edmotnon to Fort McMurray in March 2016 were presented at COAA's Best Practices Conference in May. By increasing the density of the modules and recuding the total number of required trips, more value was added to the fabrication site. In addition to its potential to yield safety improvements, the initiative could also produce savings of several percentage points in total installed costs.
The committee is currently in discussions with Alberta Transportation to consider an Alberta Heavy Module (AHM) standard to facilitate improvements in safety, efficiency and competitiveness of the module assembly and the industrial projects they are built for.

A Conceptul Model for Pore Water Release from Coal Waste Rock Piles in the Elk Valley, British Columbia, Canada Terryn Kuzyk, Clifton Associates; S. Lee Barbour and M. Jim Hendry, Department of Civil and Geological Engineering, University of Saskatchewan (Saskatoon, Canada)
The open pit mining of coal results in the formation of new landforms constructed from waste rock. Rock drains, either constructed or formed during dumping by natural segregation, underlie some of these landforms. Constructed rock drains are often designed to convey surface water from higher in the watershed through the waste rock dumps. Rock drains also collect water moving through the waste rock and convey it to adjacent surface and ground water. Long-term monitoring of the chemistry of water conveyed by rock drains provides an opportunity to characterize the rates of flushing of these constituents through the waste rock piles. In this study, a conceptual model for the long-term release of nitrate (NO3), selenium (Se), and sulfate (SO4) from coal waste rock piles is developed and used to interpret monitoring data from eleven rock drains of varying ages in the Elk Valley, British Columbia. The hypothesis of the conceptual model is that the flushing of the first pore volume of water within the waste rock can be characterized by NO3 release. The NO3 is derived from blasting and is considered to be a conservative species. The first pore volume will also contain SO4 and Se generated by oxidation of waste rock during blasting and pile construction. Post-depositional oxidation and production of SO4 and Se are identified by the evolution of the effluent signature from an initial SO4/NO3 ratio, representative of the initial pore fluid at deposition, to an increasing SO4/NO3 ratio as the initial pore volume is released and Se and SO4 are produced by oxidation. This hypothesis is tested by interpreting the patterns of NO3, SO4, and Se release as described by SO4/ NO3 and Se/SO4 ratios. In cases where upstream sources are contributing to the observed flow and concentrations within the rock drain, an attempt is made to correct the monitoring data so that it represents only the contribution from the waste rock overlying the rock drain. The concentrations of NO3 and SO4 were found to correspond to differences in the chronology of waste rock placement, while the Se/SO4 ratios were relatively constant and consistent with ratios associated with oxidation. A model of the evolution of the effluent chemistry was developed using a system dynamics model comprised of stocks (water storage) and flows (flushing) within blocks of waste rock placed at various times within a watershed. The model illustrates how stored water volumes, rates of flushing, production rates, dump chronology, and, where applicable, upstream sources control the evolution of rock drain chemistry over time. The goal of this work is to develop methods of evaluating the impact that various dump designs might have on the timing and magnitude of NO3, Se, and SO4 releases.

Estimation of Residual Fricton Angle of Clay Soils Using Artificial Neural Networks Modelling Mostafa Zadeh, Clifton Associates; Amin Falamaki, Department of Civil Engineering – Payam Noor University, Shiraz (Shiraz, Iran)
Accurate estimation of site-specific soil strength parameters (e .g ., the internal friction angle and cohesion) is challenging in geotechnical engineering due to the limitations and complexities associated with obtaining undisturbed soil samples and laboratory shear test analysis . The residual friction angle of clay soils is particularly important parameter in slope stability analysis, especially in case of pre-existing slip surfaces and large deformations, and is commonly approximated from Atterberg limits and grain size distribution using traditional regression analysis . In this study, we tested the reliability of Artificial Neural Networks (ANNs) in predicting the residual friction angle degrees of different soil types based on their Atterberg Limits, clay size fraction and normal stress . The main objective was to find a satisfactory relationship between input and actual measured values using artificial neural network models . The effect of the network geometry on the performance of the models was also assessed . Strong correlation factors (e .g ., 0 .99) for training and testing data sets in model MLP741 demonstrate that ANNs are powerful tools for predicting soil strength parameters.
The Willows Golf and Country Club hosted Clifton Associates’ Fourth Annual Client Appreciation Golf Tournament and BBQ on May 22nd in Saskatoon. Twenty-eight teams took part in the Texas Scramble, which meant that each player had to contribute at least four drives to their team’s final score.
There were many laughs as the lively groups competed for the top spot and various prizes, including two resort golf packages provided by the Town of Nipawin. CanNorth, Vals Drilling, Maxxam Labs, Enterprise, North Rim, and Xerox sponsored holes for men’s and women’s longest drive, closest to the pin, and longest putt, awarding $200 gift cards to the winners. Capital Ford Lincoln sponsored four par 3 holes to win either a golf trip to Vegas, a golf trip to Michigan, a set of golf clubs, or a two year lease on a car if the player managed to get a hole in one at the specified hole. The Onion Lake team consisting of Philip Chief, Gary Waskewitch, Jordy Lewis, and Clifton’s Brent Allen were the ultimate winners of the tournament, taking home $150 Willows gift cards for scoring ten under par.
But Clifton Associates and their clients weren’t the only ones to benefit from the tournament, as the $1800 profits from the 50/50 and charity hole went to the Saskatoon SPCA, a local animal shelter that cares for an average of 4000 animals each year.
Clifton Associates would like to thank all sponsors and participants for making this year’s tournament a success. We hope to see you all again next year!
