THEINTERCHANGE

Q1 2021

A word from the Project DirectorI’m pleased to introduce you to ‘The Interchange’ – our Project Newsletter. On a project this size it is easy to become engrossed in our day to day work area. It is important to realise we are part of a bigger team making great strides and achieving excellent results in delivering a critical piece of infrastructure for Sydney’s road network. The Rozelle Interchange Project brings together thousands of people from diverse backgrounds, a range of skills and a wealth of experience to build an iconic megaproject.

To highlight some of the terrific work being carried out across our many teams and focus on the great ways we are seeing our project values brought to life, The Interchange gives you the opportunity to learn about the broader project and to show your family and friends the project that you are helping to deliver. Look out for the newsletter on a quarterly basis which you will receive digitally to your mobile device. I also wanted to extend a warm welcome to this year’s school-based trainees. It’s great to provide an environment where students can learn firsthand about the exciting career opportunities our industry and the project has to offer. As always, stay safe and look out for each other. Steven Keyser Project Director

Health and Safety2021 Restart Safety campaignAs we commenced work on the project for this year, the 2021 Restart Safety campaign also kicked off serving as a timely reminder to prioritise safety to:

Re-set: Focus on hazards and critical risks, and look out for your matesRe-focus: Plan to do the job right and challenge unsafe behaviourRe-commit: Review your work area before you restart and take a break if you need to refocus.

Most importantly, stop working if you think it’s not safe.

Hand safety awareness In addition to the 2021 Restart campaign, hand safety has been a key focus on the project recently. The safety team launched the campaign to raise awareness about one of the most common first aid injuries that occur on tunnel sites. The campaign aims to ensure workers have the right tools and gloves for each job. Drawing attention to some of the common risks faced across the tunnel sites, the 2021 hand safety campaign posters feature our tunnel workers and can be seen across the sites. We encourage you to always consider the gloves, tools and set up used for each task and whether they can ensure the safety of your hands.

Keep up to date with our COVID-19 controls To ensure we continue to keep the project operational and construction progressing, please keep up to date with the latest COVID-19 protocols through the intranet or toolbox talks. Please ensure you strictly adhere to the processes and protocols in place. We have invested a lot in ensuring we can all stay at work and safely earn an income.

Care.Rozelle Gives Back: Charity Drive At the end of 2020, we had an outstanding demonstration of our project values ‘Care’ and ‘Deliver’. With the support and generosity of our staff, workforce, the community, and JV affiliates, we exceeded our initial target raising over $50,000 and collecting more than 1000 toys and books for local charities supporting children who need it most.

CWL workforce clean up Rozelle Bay As a way to give back at the end of 2020, City West Link (CWL) workforce team members Aaron Ginn, Luke Skinner, Brittany Profke and Daniel Malone, led by Supervisor Paul Carran, scoured the Rozelle bay’s shoreline in waders and life jackets removing 18 garbage bags of litter along the fringe of the CWL site.Well done CWL team! What a way to wrap up 2020, strengthening community spirit in Rozelle and caring for the community and the environment.

Beyond International Women’s DayOn March 8, we celebrated International Women’s Day (IWD). This year’s IWD theme of #ChooseToChallenge encouraged the conversation around our continued commitment to strengthening and supporting a diverse and more equal workforce, especially in our male dominated industry. As an industry and on the project, we acknowledge that women are under-represented generally and in senior management positions.This year, senior leaders across the project made pledges to take action to support women in the industry. The pledges are displayed at each site as a sign of commitment and accountability to challenge gender inequality and foster a culture that recognises the inherent value of women in our industry. Our Senior Leadership Team will provide updates through the year on the progress of the pledges. We can all make a difference by choosing to challenge every day at work and at home and taking steps to help build a more gender equal world.

Innovate.Rozelle Interchange Project Facebook GroupWe recently launched the Rozelle Interchange Project Facebook Group. This closed group highlights some of our amazing work and provides a channel to communicate and celebrate milestones on a regular basis. We welcome everyone who works on the Rozelle Interchange Project to sign up to the page to share in our many successes together.

Drop’N’Go implemented for City West Link’s Pigtail BridgeThe Drop’N’Go system has been implemented for City West Link’s Pigtail Bridge - an elevated Shared User Path that links Annandale to the Rozelle Parklands near the M5 Cut and Cover entrance. The Pigtail Bridge is a 270 meter-long, three-span steel box girder that includes a concrete spiral ramp. Unlike traditional bridge design and construction methods, the Drop’N’Go system is undertaken in a factory before being assembled on site. After all elements of the bridge are assembled, each completed section is lifted into place. Once the bridge is pieced together it will be largely complete and fully enclosed, alleviating the risk of people, materials or machinery working and falling from heights. The assembly of this complex structure required a detailed and innovative construction plan to navigate the critical risks. The benefits of the Drop’N’Go innovation include the reduction of night works, minimisation of safety risks, cost savings and fewer disruptions to the community including less noise, lighting and traffic disturbances.

Jet fans test are underway ahead of M&E fit-outsThe Mechanical & Electrical team have started testing equipment in anticipation for tunnel fit-outs that commence later this year, with jet fans being one of the first pieces of equipment to undergo examination. In January 2021, the jet fans underwent testing in Colchester England. The tests consisted of a series of examinations which assess whether the manufactured fan met the design parameters. Examinations include sound tests, thrust tests (the force with which air moves out of the fan) and overspeed tests to ensure fans can operate above their maximum speed in an emergency.Jet fans provide longitudinal ventilation for the tunnel, pushing car exhaust and smoke to ventilation facilities that discharge the air or smoke through the ventilation stacks. These fans possess numerous innovative features, including unique mounting frames that enable faster and easier installation on the tunnel crown. The jet fans have been designed with a smaller than usual diameter to reduce the amount of tunnel excavation required. The M&E team are happy to confirm that the jet fan performance is in accordance with the required design. Having passed this major milestone, the 132 fans required for the Project are now being manufactured, with the first order due to arrive in Australia in July.

Deliver.New M5 Cut and Cover installationThe New M5 Cut and Cover (C&C) team successfully completed the installation of all precast concrete planks, which will form an important part of the C&C roof. Delivering this milestone ahead of schedule, the team have spent three months installing 197, 15-tonne planks and pouring 1400m3 of concrete. Congratulations Dennis Dang, Deane Meers and the M5 C&C team on achieving completion of these major works well ahead of schedule.

Rozelle welcomes the latest addition to Sydney skylineThe Rozelle Rail Yards team kicked off the new year with the installation of the first tower crane for the start of the ventilation facility works. At 40 meters-tall and 71.9 meters-long with the capability of lifting 41-tonnes, the crane is positioned and sized to reach the entirety of the ventilation building footprint, which is 110m long by 25m wide. The crane will assist with the construction of the three ventilation stacks, including concrete works and complex façade steelwork that will decorate the stacks’ exterior. This milestone marks the commencement of the formwork, reo and pour (FRP) works on the vent building site. The crane is anticipated to remain on site until April 2022. Congratulations Ani Varma, Dean Tauasa, Sash Despotoski and Triska McKervey and the RRY Vent Building Team for successfully conducting the crane’s installation and rescue training on site. This milestone was also made possible due to the RRY commercial team for negotiating the contract with Marrs.
