Construction productivity is a major research interest within the construction domain. Because construction is a labor-intensive industry, previous research has often focused on construction labor productivity (CLP). However, equipment is the main driver of productivity for some construction...

The long-term storage of oil sands tailings has resulted in the evolution of greenhouse gases (CH4 and CO2) as a result of residual organics biodegradation. Recent studies have identified black, sulfidic zones belowthe tailingswater interface, which may be producing toxic sulfur-containing gases....

Sand production from a poorly consolidated reservoir could give rise to some severe problems during production. Holding the load bearing solids in place is the main goal of any sand control technique. The only sand control techniques that have found applications in steam assisted gravity drainage...

Steam Assisted Gravity Drainage (SAGD) is the primary thermal recovery technology currently employed to extract heavy oil and high-viscosity bitumen from Alberta oil sands. In the nearwellbore region, the initial stresses are nearly zero, and as the SAGD chamber grows, the stresses tend to...

Sand response changes with intensity of cementation bonds between sand grains, magnitude of intermediate principal stress and with fabric anisotropy. First a critical state bounding surface plasticity model is presented in this paper. In this constitutive model, the loading surface always...

Disasters often require large-scale evacuations, and damage key infrastructure (e.g., power, transportation). With growing electric vehicle (EV) adoption and electrification of transportation, governments and utilities may face significant power challenges during disasters, especially during the...

Steam assisted gravity drainage (SAGD) is a thermal hydrocarbon recovery method by which extra-heavy oil is produced through steam injection and bitumen heating. The presence of emulsions in the produced fluid has been detected from the very beginning of SAGD deployment. However, this...

Bacteriological contamination of drinking water wells poses a challenge to many rural areas of First Nations communities in Alberta that rely on wells as the primary drinking water source for large proportions of their populations. Here we reviewed available historical data for the Samson Cree...

Climate change, extreme weather events, and human-initiated disasters necessitate resilient approaches to emergency preparedness and evacuation planning. Previous disasters, including in North America, have revealed the inadequacy of evacuation planning that is multi-modal and inclusive of...

Extreme weather events and other hazardous events often require a range of strategies to safely shelter people, distribute resources, and facilitate recovery efforts. This is particularly important for underserved populations who usually lack reliable access to shelters, transportation, and...
