Scope of work by Antec

Supply of approximately 25,000 shear studs for structural steel and composite deck interfaces.

Background

The Warringah Freeway Upgrade is a city-shaping project that simplifies interchanges, renews bridges and integrates with the Western Harbour Tunnel to improve traffic flow and safety across the harbour corridor.

Challenge

Tight staging within Australia’s busiest road corridor demanded precise sequencing, night works interfaces and dependable materials supply to align with bridge replacement and deck pour windows.

Antec’s solution

Antec provided headed shear connectors to suit composite bridge deck design, with staged deliveries aligned to traffic and construction staging.

Implementation

• Batch deliveries timed to pour sequences and temporary works windows
• Product traceability and weld procedure documentation supplied to site
• On-call coordination for night shift and weekend possessions

Benefits and results

• No supply-related delays during critical deck works
• Consistent weld performance and compliance documentation supported QA closeout
• Improved programme certainty for the contractor team

Key takeaways

• Reliable stud supply reduces risk on complex live-traffic bridge works
• Close supplier coordination is essential when staging and access are constrained
