Research

Horizontal Directional Drilling (HDD)

Working with our partners at The Crossing Company, we have documented and analyzed risk events of over 100 HDD projects throughout Alberta and British Columbia. With financial and in-kind support from TCC and a major grant from NSERC, we are working towards developing a comprehensive risk database and risk management strategy for HDD projects. Significant findings from our research thus far have been presented at the annual NASTT No-Dig Show and through our own HDD Planning and Design short course.

Pilot Tube Microtunneling (PTMT) and Pipe Bursting

Both PTMT and Pipe Bursting are used by the City of Edmonton for major urban pipeline installation and rehabilitation projects; however, Alberta's unique cold climate presents special challenges for underground infrastructure and construction. Our research is focused on documenting these challenges and their impact on project cost and schedules and creating innovative solutions for Canadian municipalities with similar climates. 

Pipeline Condition Assessment 

In further collaboration with the City of Edmonton, CETT researchers are investigating the municipality's current pipeline assessment protocol and comparing it to other protocols used around the world to zero in on the most efficient techniques for pipeline classification and prioritization for maintenance. This study will make a significant contribution to municipal asset management strategies. 

Cured In-Place Pipe (CIPP)

This research involves working through all stages; planning, design and construction, of IVIS Inc.'s CIPP projects to identify risk events and develop management strategies for the events that have the most impact on project delivery. 

Telus Fibre to the Home (FTTH) Research Project

In collaboration with Telus, CETT researchers are studying the most cost-effective installation methods for FTTH deployment where there are no exiting telco rights of way. This project comes as a result of an increased dependence on the internet; the changing habits of internet users require larger bandwidth, and Telus aims to deploy fibre that can carry their clients near unlimited bandwidth. Our research in this area will provide the Canadian telecommunications industry with scientifically-backed knowledge and procedure for future installation projects.

Tunnel Boring Machine (TBM) Clogging Potential

Alongside the City of Edmonton and new associate member Neptune Coring, CETT researchers are addressing issues related to the clogging of TBM in Edmonton boring projects. This project will be assessing ground conditions in City projects to determine the presence of clay, which commonly causes clogging problems during boring operations. Researchers are gathering information from current projects to compile a comprehensive database that can aid in the planning and design of future projects.
