Join us for an educational luncheon on Navigating Geotechnical Risks in Urban Environments: Lessons from Amsterdam and Calgary.
This presentation explores the complexities of underground infrastructure development in sensitive urban environments through two distinct tunnelling case studies.
The first case study examines the high-stakes construction of the North-South metro line in Amsterdam. Following historic public resistance to open-pit construction in the 1970s, planners adopted Tunnel Boring Machine (TBM) technology to minimize surface disruption. However, navigating a TBM through soft soils beneath a city, supported by 400-year-old wooden piles, posed a critical engineering challenge. This segment discusses the strategies employed to mitigate settlement risks and protect 17th-century heritage buildings from structural damage during tunnel excavation.
The second case study shifts focus to Calgary, Alberta, detailing the geotechnical assessment and execution of a trenchless storm trunk crossing beneath the Canadian Pacific Kansas City (CPKC) Railway right-of-way. The project, using a Herrenknecht AVN1800 Microtunnel Boring Machine (MTBM), involved installing a 63-meter concrete tunnel with a diameter of 2,224 mm. This section outlines the protocols required to secure a crossing agreement, including the geotechnical investigation, settlement analyses, and adherence to strict allowable settlement limits. It further reviews the implementation and results of the settlement monitoring plan, which successfully assured the safety of ongoing rail operations during the trenchless installation.
These projects highlight the role of geotechnical assessment and monitoring in overcoming the challenges of tunnelling beneath historic foundations and active transportation corridors.

Join us for an educational luncheon on Technical Specifications for Gravity CIPP Rehabilitation: Should You Stick with ASTM F1216 or Move to ASCE MOP 145?
For decades, the trenchless rehabilitation industry has relied on ASTM F1216 as the primary design and specification reference for Cured-in-Place Pipe (CIPP) rehabilitation of gravity sewers in North America. However, after a newer structural design framework (i.e., ASCE MOP 145) was introduced in 2021, questions are emerging about whether the traditional F1216 approach remains sufficient for modern rehabilitation challenges. This presentation examines the practical implications of specifying CIPP designs using F1216 versus the newly introduced MOP 145. While ASTM F1216 provides a straightforward and familiar design method, it was originally developed for relatively ideal conditions and does not fully address challenges such as non-circular pipes, large deformations, significant defects, or significant variability in liner material properties. ASCE MOP 145 introduces a Load and Resistance Factor Design (LRFD) methodology that accounts for uncertainties in loads, material performance, and installation conditions. This approach allows more accurate and defensible liner designs while improving alignment between engineering expectations and contractor means and methods. This presentation provides practical guidance for Utility Owners, Engineers, and Contractors on when ASTM F1216 remains appropriate and when the enhanced framework of ASCE MOP 145 may offer better reliability. The session will walk through the procedural steps of both F1216 and MOP 145. Case studies and design comparisons will illustrate how both approaches can be applied to support informed specification and long-term performance of gravity sewer rehabilitation projects.
Presenter: Kay Awe
Kay is a Senior Trenchless Engineer at Stantec with technical expertise in structural design, geotechnical assessment, pipeline design, rehabilitation, failure analysis, and condition assessment. He is a registered professional engineer in Alberta & Ontario, and has worked on a wide range of trenchless projects across Canada and the US, utilizing cleaning and lining technologies for water/wastewater systems. Kay earned his PhD from the University of Waterloo and is very passionate about advancing the trenchless industry. He is actively involved in professional organizations through the ASCE/UESI Young Member Engagement Committee, NASTT Northwest Planning Committee, CUIIC Geotechnical Committee, and multiple AWWA pipe rehabilitation committees. He is also one of a few SMEs in North America currently contributing to the development of the first AWWA C623 CIPP Pressure Pipe Design Appendix.
