SUMMARY:Event: The Effectiveness of Rail Web Dampers and How They are Selected and Implemented
DESCRIPTION:Rail dampers were developed in the 1990s as a way of reducing noise from railways. They work by attaching to the existing rail directly between fasteners\, and by reducing vibration in the rails the amount of noise produced is reduced. However\, rail dampers are also able to improve long-term rail conditions and reduce costs of maintenance over the asset lifecycle. \nSpeaker\nLuke Zoontjens\nTechnical Director – Acoustics & Vibration at SLR Consulting Australia Pty Ltd\nAcoustics engineering consultant with 18 years of professional experience and a focus on technical research and business development. Practice lead\, responsible for delivery of acoustical engineering services in Western Australia for environmental consultancy firm SLR Consulting Australia Pty Ltd. Special interests are in transportation noise and vibration\, education and healthcare facility design; building services noise control and architectural acoustics; specialist recording and performance spaces; environmental noise impact studies; and advanced technical investigations. \n\n\n \nClick here to register for the webinar now!

SUMMARY:NZ Chapter Event: Working Stress- the New Zealand rail bridge rating story
DESCRIPTION:Join the RTSA New Zealand Chapter and Mike Keenan (KiwiRail) to hear about the history of how rail bridges in New Zealand are “rated”. This presentation is being held as an RTSA New Zealand online meeting. \nKiwiRail maintains a substantial rail infrastructure network of which its bridge stock are an essential component. These bridges have been developed over the 160 year life time of New Zealand’s railway and are a key enabler of the networks overall capacity. How these bridges are “rated” to determine their load carrying ability has likewise developed over time. This presentation will describe the background to choices made\, the influence of other overseas railways\, how the rating is now done and some of the challenges that the network faces. \nMike Keenan is part of the team responsible for engineering oversight of KiwiRail’s structures assets. He has been working on inspection\, maintenance and renewal of the rail network in New Zealand for the past 15 years. \nClick here register on the Engineering New Zealand website.

SUMMARY:NZ Chapter Event: North Auckland Line (NAL) – Bridge and Tunnel upgrade works
DESCRIPTION:Join the RTSA New Zealand Chapter in Wellington\, Auckland\, Christchurch or online for a presentation on North Auckland Line (NAL) – Bridge and Tunnel upgrade works. Register here. \nThis presentation will consist of 2 parts: \n\nBridge presentation by Holmes Consulting\nTunnel presentation by Aurecon\n\nPart 1: Bridge Presentation by Holmes Consulting\nForming part of the Northland Rail Upgrade Project\, Five Bridges were replaced across the North Auckland Rail Line. With 9 months programmed from awarding tender for design to practical competition of construction\, programme posed a significant hurdle. Along with Covid-19 restrictions and the resulting supply chain issues\, the project called for a ‘one team’ approach. Where possible\, standardisation was implemented across the project and fast construction techniques such as segmental bridge construction were adopted to reduce onsite construction time. The presentation looks to cover some key challenges that the design team faced throughout the project journey. \nMatt Ireland – Senior Project Engineer – Holmes Consulting\nMatt is based in Holmes Consulting’s Christchurch office and has over 14 years of structural engineering experience in the design of bridges and civil structures. He specialises in the delivery of major infrastructure projects across the country and has been involved with a number of significant road\, rail and pedestrian bridge structures. \nAidan is based in Holmes Consulting’s Auckland office and has been working in the civil structures team for 4 years since graduating from university. In this time he has worked across a number of horizontal infrastructure projects\, carving an interest in soil-structure interaction and construction management. \nPart 2: Tunnel presentation by Aurecon\nLouise\, Harry and Shu Fan will together talk about the tunnel design on the NRU. \nIn Northland Rail Upgrade Project (NRU)\, Shu Fan was the tunnel design lead for the 7 out of 13 most challenging tunnels of the North Auckland Line (NAL). Shu Fan Chau is an Associate in tunnels and the NZ Tunnel Lead at Aurecon. In addition to TBM tunnelling\, his wide-ranging tunnel expertise includes mined tunnels and caverns\, drill and blast tunnelling\, immersed tube tunnelling\, cut- and-cover tunnels\, deep excavation\, underground structures\, site formation and slope works. Shu Fan has worked on Waterview Tunnels in Auckland\, West Gate Tunnels in Melbourne and is currently working in City Rail Link. \nHarry Asche is a Design Director in Aurecon and he has worked on tunnels in New Zealand\, Australia\, UK and HK.  He is an Adjunct Professor at the University of Queensland and is the current President of the Australian Tunnelling Society. \nLouise Wotton is a computational designer at Aurecon\, Computational design works to improve delivery through creation of custom digital tools and the development of automated pipelines to produce consistent\, high quality deliverables. \nDuring the North Auckland Line upgrade Aurecon developed a custom software package to generate rail gauges along the alignment and run clearance analysis checks. Over the course of the project this evolved to include drawing automation\, kinematic calculations and generative solvers to build a ‘best fit’ for a new alignment in the tunnels to accommodate new rolling stock. \n\nYou can join us in person or online for this event: \n\nWellington – Engineering New Zealand\, L6\, 40 Taranaki Street\nAuckland – Aurecon\, Level 3/185 Fanshawe Street\nChristchurch – Aurecon\, Level 2\, Iwikau Building\, 93 Cambridge Terrace\nOnline via MS Teams (Please note online start time is 6pm)\n\nClick here register on the Engineering New Zealand website.
