Case Study

Hornsby Platform 5 and Stabilising Works

Client: Laing O'Rourke / TIDC
Location: Hornsby, NSW
Project Type: Rail - Horsnby Platform 5 Stabilising Works
Duration: 28 weeks
Scope of Work:
The ‘L’ Shaped Retaining Wall is part of a $50 Million redevelopment and expansion of rail infrastructure at Hornsby Station and the immediate surrounding areas financed by TIDC. The wall undertaken by Hannas has a construction value in excess of $2.5 Million. The retaining wall is 200 metres long and at its highest point is over 8 metres tall. The purpose of the ‘L’ Shaped retaining wall is to retain fill upon which additional stabling yards for trains will be constructed.

The project offered several challenges for Hannas including working within the rail environment, rigorous OHS & QA requirements, and strict adherence to rail building specifications. An additional challenge was working adjacent to existing rail lines and a main road with complex planning considerations required to ensure site and public safety as well as general traffic access.

Project Statistics:
• Wall Length – 200 metres
• Wall Height – From 4metres up to a maximum of 8 metres
• Overall Square meters of Retaining Wall – 1500m2
• Over 11,000m3 of Bulk Excavated Material had to be managed on site
• The ‘L’ Shaped Retaining Wall was constructed in three phases: Base Footing, as well as 2 Vertical Lifts
• 57 separate wall component concrete pours
• A total of 1720m3 of Concrete
• A total of 260 tonne of Steel Reinforcement
• Reusing the 11,000m3 of bulk excavated material as backfill ready to take rail track.
