Join us for an educational luncheon on the microtunnelling methods currently being used on the Lauderdale New Storm Trunk and Sanitary Trunk.
Lauderdale New Storm Trunk and Sanitary Trunk are under construction using microtunneling methods. The two TBMs are using the same working shaft. This presentation will introduce the project background, challenges, and the cooperation between owner and contractor on addressing the challenges through delegated design model.
Presenter: Chaoshi Hu, PhD, P.Eng,
Chaoshi Hu, PhD, P.Eng, is a structural engineer with EPCOR Water Services. He has 16 years’ experience in the design and construction of underground infrastructures; has designed and constructed 16 kilometers of drainage tunnels, and over 60 deep shafts. Delivered over $400M underground infrastructure projects.
He is volunteering in NASTT-NW Chapter as vice president. He has authored three papers at NASTT No-Dig Conference and WWC Conference.
Peiqian (Jan) Zheng, project manager with Shanghai Construction Group (Canada). Jan has over 10 years’ experience in underground and TBM/MTBM tunneling construction. And Jan has successfully delivered multiple drainage infrastructure projects for EPCOR.
Join us for an educational luncheon on a Case Study in Close-Fit Spiral-Wound Lining.
Large-diameter sewer rehabilitation projects often present a combination of structural, hydraulic and constructability challenges that cannot be addressed through technology selection alone. Access limitations, existing pipe geometry, flow management, site constraints and long-term performance requirements can all influence the most appropriate rehabilitation approach.
Using the City of Portland’s Carolina Trunk Sewer rehabilitation as a case study, this presentation will examine the evaluation and application of close-fit PVC spiral-wound lining technology for a challenging large-diameter gravity sewer. The discussion will focus on how project-specific conditions informed rehabilitation selection, the relationship between design requirements and field constructability, and lessons carried through installation and verification.
The presentation will conclude by considering how these decision-making principles may translate to large-diameter sewer rehabilitation in Edmonton and across Alberta, and where spiral-wound lining may fit within the broader trenchless rehabilitation toolbox available to owners, engineers and contractors.
