WSP was the Independent Verifier (IV) for Transport for NSW (Transport) and Ferrovial Agroman and York Civil Joint Venture (FYJV) who delivered the project. Through close collaboration with our clients, we helped to overcome key brown-field project challenges while providing independent assurance to both Transport and FYJV that ensured delivery of a safe, value for money project with enduring service to the community.
The key project challenges centred around the safety of the workforce, road users and the community; quality and durability of the end-product and environmental compliance such as dust, run-off and noise management during and after project completion. Some of the key project challenges included:
- Managing utility services and live traffic in a built-up area
- Unforeseen durations of extended working hours including extended periods of high impact night and weekend work affecting road users, the local community and workforce
- Attending significant traffic switches and road closures.
Independent verification helps identify and bring instances to clients’ attention where construction may deviate from the scope of works and technical criteria, specifications or design drawings, and therefore could impact the quality and durability of the final product. As part of our work, we monitored the implementation of the quality system, project deliverables and provided independent design and construction verification services for project works, temporary works, landscaping and project performance.
All up, WSP reviewed more than 80 design packages, involving three underpass bridges and two shared use bridges, key intersection improvements, bus stop upgrades, noise barriers, retaining walls, pavements, stormwater drainage, footpaths and shared use paths.
We helped identify and resolve many potential day-to-day issues, such as misaligned drainage fixtures, missed soil nails, wrong kerb types and lines and signage errors before they became issues, both at design and construction stages.
To ensure all works were delivered safely, WSP made comments on all Safe Work Method Statements, Traffic Management Plans and Environmental Management Plans, including erosion and sediment control; noise and dust monitoring and management plans. We also conducted quarterly in-house and external audits on FYJV’s quality, safety, traffic and environmental management processes and products on site as well as at off-site plants and suppliers.
Adrian Chuma, WSP’s Senior Project Manager and Project Verifier’s Representative, said, “As a team, we collaborated with all the other parties involved and the broader community. Our ability to adapt and resolve concerns or escalate issues in a timely manner made a big difference to our relationships with the other parties and ultimately, the project’s success."
Better, Smoother Travel for All
The project widened and upgraded roads to improve essential access to the Northern Beaches Hospital. In addition, Warringah Road was widened to allow for a 1.3 kilometre-long, four-lane open-air underpass through the middle of the new Warringah Road surface lanes, providing an extra two lanes in each direction.
Every day, more than 140,000 vehicles use these roads to travel through and around the area. All will now have a much better travel experience.
