M4-M5 LINK MAINLINE TUNNELS
The key features of the project include﹕
• Twin mainline motorway tunnels between the M4 East at Haberfield and the New M5 at St Peters. Each tunnel is approximately 7.5 kilometers long and generally accommodates up to four lanes of traffic in each direction
• Connections of the mainline tunnels to the M4 East project, comprising：
➢ A tunnel-to-tunnel connection to the M4 East mainline stub tunnels east of Parramatta Road near Alt Street at Haberfield
➢ Entry and exit ramp connections between the mainline tunnels and the Wattle Street interchange at Haberfield (which is currently being constructed as part of the M4 East project)
• Connections of the mainline tunnels to the New M5 project, comprising：
➢ A tunnel-to-tunnel connection to the New M5 mainline stub tunnels north of the Princes Highway near the intersection of Mary Street and Bakers Lane at St Peters
➢ Entry and exit ramp connections between the mainline tunnels and the St Peters interchange at St Peters (which is currently being constructed as part of the New M5 project)
• Tunnel ventilation systems, including ventilation supply and exhaust facilities, ventilation fans, ventilation outlets and ventilation tunnels
• Drainage infrastructure to collect surface and groundwater for treatment at dedicated facilities
• Emergency access and evacuation facilities, including pedestrian and vehicular cross and long passages and fire and life safety systems
Carrabay were contracted to perform the FRP (Form, reinforcement and concrete) to the new permanent water treatment plant at the SPI (St Peters Interchange) site on the M4-M5 Link tunnels project.
Carrabay were also contracted to procure, cut, bend and pre-fabricate reinforcement cages to a number of structures at the SPI site including capping beams, columns and ground beams.|
SPECIFIC DETAILS：
Carrabay supplied and installed all the reinforcement to the Water Treatment Plant including scheduling and 3D modeling. All temporary works for the shuttering system were installed and dismantled by Carrabay FRP team. The concrete was poured into the relevant structures by use of concrete pumps or directly from the back of the concrete agitator. The finished concrete was finished and cured as per the requirements of the project specification.
Carrabay also provided pre-fabrication solutions and reinforcement install to the building structures, retaining walls and ventilation building.
Carrabay liaised with both the client and fellow subcontractors to ensure that the project was delivered successfully without delay through interface meetings, logistic co-ordination, utilisation of shared resources (Cranes for example).
Our delivery team and FRP crews on this project were highly praised for our safety culture and care for quality.
From the feedback received it was a positive project delivery for all involved successfully delivering the project on site, on budget with a very happy client.
