Seismic performance of helical pile groups and their cost efficiency as alternative to driven piles

A new seismic hazard model of Canada will be incorporated in the NBCC2020, which will increase the seismic hazard by 50-100%. Meanwhile, helical piles are a reliable and cost-effective alternative to conventional driven piles because of their fast installation, lower cost and lower labour risk. They are suitable for retrofitting existing deficient foundations because they require smaller installation equipment that cause minimal vibration and noise during installation.

Paving the way to concrete 3D printing for sustainable housing in cold regions

These two first units are sub-projects of a larger feasibility study that looks to solve the challenges that prevent the construction of housing in remote northern areas of Canada despite overwhelming need. Using 3D printing to accomplish quality housing projects in remote climates requires further research prior to being deployed. The larger context pf this project is to establish the technology, methodology and practices of building appropriate housing in Northern communities.

Urban microclimate modeling for sustainable building design

Buildings in Canada consume 29% of the total energy and 58% of the electricity on an annual basis. Through optimal sustainable design, however, there is an opportunity to reduce a building’s energy consumption as high as 80%, and the remaining 20% energy consumption can be produced from renewable sources. Sustainable design requires consideration and integration of climate responsive designs, building forms, and building envelope component details. Building façade plays a crucial role in meeting building energy efficiency and internal thermal comfort demands.

Using RTLS and Computer Vision to Extend Worksite Safety

The project aims to extend worksite safety of construction projects at Hydro-Quebec (HQ) using computer vision and a Real-Time Location System (RTLS). The case study is a substation construction project near Montreal. The main safety risks that will be targeted in the case study are related to equipment mobility (struck-by accidents) and not wearing Personal Protection Equipment. The concept of the method is to have a priori information about the types of expected risks in the planning phase, and then to monitor the site using video cameras and the RTLS.

Developing a Compact, Medium Range 3D Imaging LiDAR System

The main technical objective for the intern is to contribute in developing a breadboard that utilizes the laser, receiver and scanner technologies and create a potentially very small lidar.
The intern other objectives might also include:
• Investigate the transmitter choices and down?select the best one
• Examine the available detector arrays
• Evaluate whether MEMS mirrors can be used for low?power, high?frame rate applications
Adoption of compact lidar technologies is critical for Optech to remain competitive in the expanding market for lidar solutions.

Development and validation of natural source zone depletion quantification protocols for sustainable remediation of hydrocarbon-contaminated sites

The extraction, storage, conveyance, and refining of petroleum hydrocarbon liquids (or nonaqueous phase liquids (NAPLs)) often result in their accidental release into the environment. Consequently, NAPLs will travel into subsurface soils and may enter groundwater, further exacerbating the extent of contamination. Aside from being energy-intensive, disruptive of the environment, and incur treatment durations that may span several years, typical engineered remediation technologies may not capture all of the NAPLs in-place.

Advancing municipal natural asset management in engineering practice and beyond

Canadian local governments are seeking new strategies to deliver their core services in more financially and environmentally sustainable ways, including turning to infrastructure asset management as a key tool to manage infrastructure. Municipalities are increasingly recognizing that natural assets such as aquifers, forests, streams and foreshores can provide equivalent or better services to many engineered assets.

Optimization and modeling of BioCord fixed-film technology for nutrient and organic carbon removal from domestic wastewater

Many biological wastewater treatment options are available, ranging from advanced technologies to conventional treatment options. Fixed-film biological wastewater treatment systems are in an increasing demand for conventional plant upgrades. In this study a fixed-film media called BioCord, developed by Bishop Water Technologies, will be used. The research will propose a new opportunity to enhance the removal of contaminants (such as organic carbon and nitrogen) at higher intensity and lower energy input.

Determination the effectiveness of drought resilient bioretention bed in stormwater management

The greatest river in Calgary, Bow River, is an important source of water for industrial, agricultural and living activities for city and people of Calgary. With the incredibly fast of urbanization in Calgary, the natural landscapes are gradually replaced by impervious areas, such as urban streetscapes, houses and buildings.

Innovative Sustained High Strength Silicate Based Shotcretes

Due to early strength requirements, shotcrete mix must incorporate rapid set accelerating agents to speed up mix set time and accelerate hardening. Silicate-based shotcrete accelerators have demonstrated good early compressive strength, short set time and good stiffening properties at relatively low cost. The silicate-based shotcrete mix also has minimal impacts on health, environment and improved safety. However, it can exhibit relatively significant loss of compressive strength over 28 days, which presents a critical challenge.
