Project Overview:
The M6 Stage 1 project is for the design and construction of the first stage of the M6 motorway, extending from the M8 motorway at Arncliffe to President Avenue at Kogarah.
Project Description:
Quickway have been engaged to undertake the FRP works for Water Treatment Plant Building located at 19 Marsh Street Arncliffe, NSW. The scope of works included the construction of the following:
- Installation of services for the water treatment plant
- Concrete blinding of the whole slab area (circa 1,400m2)
- Construction of sumps
- Form, reinforcement and pour for Rainwater Tank and Equipment Slab
- FRP for base slab and 8m tall in-situ columns, totalling 150T+ of steel reinforcement and 500m3 of concrete
- Installation of 21 precast concrete wall panels, weighing over 20T each, utilising the use of a 350T crane in a heavily congested environment.
- Large amounts of falsework to form up the roof slab, approx. 8m above the base slab.
- Top-up plinths for various foundations including Nitrate Filters, Pump Skids, Surface Water Holding Tank, Sludge Tanks, Coagulant Chemical Tank, Sulphuric Acid Dosing Tanks, Sodium Hydroxide Chemical Tank, Sodium Hydroxide Chemical Tank, and many others.
- In-situ Concrete Retaining wall construction
Key Challenges/Highlights:
- High‑risk construction activities requiring strict safety management
- Multiple temporary works designs needing coordination and approval
- Very tight project deadline
- Highly congested work area limiting access and manoeuvrability
- Safely installing falsework for the roof slab 8 metres above the base slab
- Successful delivery of complex works despite difficult conditions
- Installation of 21 precast concrete wall panels weighing over 20T with the use of a 350T crane
- Completion of the roof slab, 8m above ground level
- High quality finished works
- Works completed without incident
- Zero NCRs to date on this scope
