SUMMARY:Hobsons Bay main Yarra crossing duplication project
DESCRIPTION:The Hobsons Bay Main Sewer (HBMS)\, constructed in the 1960s\, transfers approximately 30 per cent of Melbourne’s wastewater to the Western Treatment Plan at Werribee. \nThe sewer alignment has a single sewer crossing under the Yarra River\, which has deteriorated to a point where it requires rehabilitation and/or replacement. The Hobson Bay main Yarra crossing duplications project is the construction of a new sewer alongside the current HBMS to ensure there are no disruptions to the critical sewer network and will allow for the future uninterrupted rehabilitation of the existing crossing. \nThis presentation covers the design and construction of the new sewer; tunnelling and excavating shafts in difficult ground conditions\, constructing shafts over the critical live sewers\, completing the live connections and bringing the new sewer successfully into service. \nATS Platinum Sponsor John Holland. \nProgram\nOnline: \n\n6.00 pm AEST: Presentation and Q&A\n\nIn-person: \n\n5.30 pm AEST: Guest arrival\, registration\, networking\n6.00 pm AEST: Presentation and Q&A\n7.00 pm: Event ends\n\nAbout the speaker\n\n\n\nNick Cox\nConstruction Manager\, John Holland\nBiography\nNick is a Construction Manager at John Holland. During his 16 years as a civil engineer with John Holland\, Nick has specialised in major road\, rail and water infrastructure tunnelling projects in Victoria\, NSW and Queensland. \nHis expertise includes TBMs\, pipejacking\, mined tunnelling\, ground treatment and shaft sinking in both hard and soft ground. Nick has been at the forefront of implementing key project innovations such as the use of glass-reinforced plastic linings and manholes and the development of mechanical flumes for live sewer diversion works.

SUMMARY:ITA Lecture - Practical Aspects of Segmental Tunnel Lining Design
DESCRIPTION:Topic: Practical Aspects of Segmental Tunnel Lining Design \nAfter several decades of continuous progress\, mechanized tunnelling has now become the main method applied in almost all types of geology\, all sizes\, and in increasingly shorter lengths. The predominant excavation support system for TBM tunnels consists of a one-pass precast concrete segmental liner which in addition to typical use in soft ground contexts is also increasingly applied in competent rock settings to better manage the geotechnical and hydrogeological risks. The first presentation of this lecture covers necessary details for analysis and design and provides in-depth information allowing tunnel engineers to start designing tunnel segmental linings. The required elements of concrete technology are presented in the second presentation and the last presentation describes the use of fiber for reinforcing segmental linings which has become the preferred solution for most cases. \nThis instalment of the Lunchtime lecture series will focus on practical Aspects of Segmental Tunnel Lining Design. \nThis episode will feature three lectures: \n\nBasic Principles of Tunnel Segmental Liner Analysis and Design – Verya Nasri\nTechnology challenges to meet sustainability goals of concrete used for tunnel segmental linings – Barzin Mobasher\nUse of Fiber for Tunnel Segment reinforcement – Benoit De Rivaz\n\nFollowing the three presentations there will be time for Q&A with the presenters. \n  \n \nVerya Nasri\, AECOM \n \nBenoit De Rivaz\, Bekaert Underground Solutions \nThe Lunchtime lecture series remains free and open to all. For all those that cannot join ‘live’ online\, please register and you will receive a link to stream the episode after the event – this link will be valid for 24 hours only. After these 24 hours\, anyone wanting to watch the episode can do so by registering for the episode on the ITA website\, but there will be a small fee to watch. \nRegister for the events here: https://www.itacet.org/sessions/forthcoming

SUMMARY:North East Link SEM Ventilation Tunnel and Adit Construction
DESCRIPTION:Overview \nThe construction of the North East Link (NEL) tunnels is well underway! The largest transport infrastructure project in Victorian history consists of 6.5 km tunnels from Watsonia to Bulleen\, and it will complete Melbourne’s orbital freeway network. The presentation will provide an overview of the recently constructed ventilation tunnel and adits using Sequential Excavation Method (SEM). The key topics include primary support types and selection criteria\, construction sequence and methodology\, observational ground behaviour and support optimisation on site. This presentation offers an exclusive look into the mega project\, detailing the entire timeline from design to construction. It provides a unique opportunity to showcase the comparison between tunnel design considerations and field observations\, with the intention to bridge the gap between theory and practice. \nLearning outcomes \nThis presentation you will learn: \n• Regional geology and how the project classifies the rock mass for tunnel support selection. \n• The roles and responsibilities of the CPS team in the field and how they provide advice on “as required” support installation. \n• An overview of the detailed design process and how the North East Link team are bridging the gap between design and construction through design and constructability optimisations. \nTimings \nOnline: \n6:00pm AEDT: Presentation and Q&A \n7:00pm AEDT: Webinar ends \nIn-person: \n5:30pm AEDT: Guest arrival\, registration\, networking \n6:00pm AEDT: Presentation and Q&A \n7:00pm AEDT: Event ends \n  \nSpeakers \n \nBrooke Carnes \nSenior Project engineer\, DELVE Underground \nBrooke is a Senior Project engineer at Delve Underground with 10 years of experience in tunnelling on a wide range of transportation and water projects\, both in Australia and internationally. She has design experience in metro rail\, road tunnel and large-scale underground structures. Brooke was the SEM mainline tunnel Package Lead on the North East Link Program Detailed Design Phase and is now working as a Field Professional providing Construction Phase Services to SPARK for the construction of the SEM scope on this project. \n \nHeather Hughes-Adams \nProfessional geotechnical engineer\, DELVE Underground \nHeather Hughes-Adams is a professional geotechnical engineer with 6 years of experience in the industry. She joined Delve Underground in Vancouver in 2021\, where she has used her background in site investigation and trenchless construction engineering to support her work in trenchless technology\, including the design and construction of horizontal directional installations and pipe rammed crossings. Since joining the Melbourne office last year\, Heather has begun working on large scale transportation tunnels\, starting with the North-East Link project where she works full time on Construction Phase Services.
