Sep 29, 2022Lone Star Texas Grill (930 Dixon Rd, Toronto, Ontario)TAC Ontario Chapter Event The City of Ottawa​ Combined Sewage Storage Tunnel:​ The Why, the What and the How
Presentation Overview:

The City of Ottawa embarked on an ambitious action plan to improve the quality of the Ottawa River. One of the key initiatives was the building of the Combined Sewage Storage Tunnel which reduced the number of Combined Sewage Overflows and basement flooding in the area. This presentation will discuss the project objectives and the building of the two intersecting tunnels located in downtown Ottawa totaling 6.2km in length, each 3m finished diameter, up to 30m deep, with a single pass tunnel construction all in rock.

Gerald Bauer is a Principal of Stantec Consulting Ltd. working in the Municipal Infrastructure area with a focus on trenchless technologies for over 35 years. He has presented at various infrastructure focused conferences on numerous trenchless topics from new installation to rehabilitation. Gerald provides trenchless expertise across North America to support the Tunneling and Trenchless teams within Stantec and has been a member of six Value Engineering sessions on large diameter infrastructure.

Registration begins at 5:30pm and presentation will begin at 6:00pm.

Oct 19, 2022MS TeamsTACym Learning Series - Precast Concrete Tunnel Lining (PCTL)
The TAC Young Member’s Committee is excited to announce the return of the educational series for our members. Focused on introductory topics, the webinar series will strive to teach basic tunnelling themes not often taught in school but beneficial to those working in the industry. If you’re a student, just starting your career, or someone who likes to continually learn, then you’ll be sure to pick-up something new.

Abstract:

Our next topic will be the Precast Concrete Tunnel Lining (PCTL). Learn the parts of a segmental ring, their benefits over other lining types and how they are created. Typical loads, how engineers commonly design segments are discussed and reinforcement options are highlighted.

Speaker Bio:

Michael Dutton, P.Eng works with Arup Canada as a Senior Tunnel Engineer in their Toronto Office. He received a Masters in Structural Engineering from Queen's University, Kingston Ontario, in 2012 before joining the Underground Infrastructure team at Hatch (formerly Hatch Mott MacDonald) in Mississauga. During his 10 years in the industry, Michael has gained a wide range of engineering design experience related to underground construction in a variety of ground conditions. On the job learning taught him the ins and outs of ground structure interaction and advance constitutive models. Project highlights include the Great Lakes Tunnel Project, Scarborough Subway Extension, and the BART Silicon Valley CP2.

Sydney Metro City & Southwest –
Tunnel & Stations Excavation (TSE) WORKS

Presentation Overview:
Built in the heart of Sydney’s central business district, the project includes 15.5kms of fully lined twin tunnels between Chatswood and Sydenham (five TBMs employed), along with 57 cross-passages and two permanent dive structures, seven underground stations and numerous rail corridor widenings, shafts and caverns. Technically complex with challenging logistical and geotechnical conditions, Ghella, along with joint venture partners, used many sustainable solutions to deliver an array of Australian construction “firsts”.

Speaker Bios:
Tommaso Stancato, a civil engineer by education, has been working with Ghella since 2016, mostly on overseas tunneling projects where he contributed to both construction operations and as a technical expert during tendering. He will present the Sydney Metro City & Southwest Project where he worked for several years as a project engineer. Tommaso is currently assigned to the Eglinton Crosstown West Extension project in Toronto.

Registration begins at 5:30pm and presentation will begin at 6:00pm.
