Project Info
Client: Sydney Metro/Gamuda Project
Date: September 2023
Project Scope: To deliver an automated, space-efficient weighing solution for Gamuda Australia’s Sydney Metro project, enabling precise tracking of excavated material quantities and compliance with axle group and Gross Vehicle Mass (GVM) regulations.
Overview
Gamuda Australia, a leading contractor in the construction industry, was awarded a pivotal contract for a portion of the Sydney Metro project. This contract encompassed a substantial scope of work involving excavation and the removal of a significant amount of material from the project site. It was imperative for the client to meticulously track the quantity of material being transported off-site. Additionally, strict compliance standards needed to be upheld, ensuring that vehicles leaving the site were not overloaded, both in terms of their axle groups and the Gross Vehicle Mass (GVM). The project faced the challenge of limited space, and there was no provision for manned weighbridge operators, making the need for an automated, efficient, and accurate solution paramount.
Solutions
NWI Group offered a custom solution for the Sydney Metro/Gamuda project. The proposed solution was an inground multideck weighbridge, specifically designed to address the unique challenges posed by the project. The key components of this innovative solution included:
Multideck Weighbridge: The weighbridge consisted of four 5-meter decks, strategically positioned to capture both the total weight of the vehicle and the weight of each individual axle group. This granular level of data collection was crucial in ensuring compliance with weight limits.
Unmanned Operation: The weighbridge was entirely unmanned, removing the need for dedicated operators. Instead, it relied on state-of-the-art automation technology to streamline the weighing process.
Driver Terminal: A user-friendly driver terminal was integrated into the system, enabling drivers to input essential information and receive real-time feedback on their vehicle’s weight status.
Traffic Management: Traffic lights were installed to manage the flow of vehicles, ensuring smooth and efficient operations at the weighbridge.
License Plate Recognition: The system featured license plate recognition technology, which automatically detected and recorded the license plates of all vehicles passing through the weighbridge.
Benefits and Results:
NWI’s innovative weighbridge solution delivered substantial benefits to the Sydney Metro/Gamuda project:
Accurate Compliance Monitoring: The solution allowed the client to rigorously track the Gross Vehicle Mass (GVM) of every vehicle departing the construction site. This ensured that every vehicle was compliant and safe for road transportation, mitigating potential risks associated with overloaded vehicles.
Labor Cost Savings: The implementation of an unmanned weighbridge system resulted in significant cost savings for the client. By eliminating the need for manned operators, the client reduced labor expenses while maintaining operational efficiency.
Automated Reporting: Daily automatic reporting provided the client with precise and up-to-date information regarding the total quantity of material removed from the site. These reports complied with both National Measurement Institute (NMI) and Environmental Protection Authority (EPA) regulations, ensuring accurate record-keeping and regulatory compliance.
Transaction Monitoring and Retrieval: The system facilitated the monitoring and retrieval of all vehicle transactions at any given time. This included clear images of each vehicle’s license plate, providing an additional layer of security and record-keeping.
Outcome
In conclusion, NWI’s inground multideck weighbridge solution proved to be instrumental in meeting the complex requirements of the Sydney Metro/Gamuda project. By seamlessly integrating automation, accuracy, and compliance monitoring, NWI empowered the client to streamline operations, reduce costs, and maintain the highest standards of safety and regulatory compliance throughout the project. This case study exemplifies NWI Group’s commitment to delivering innovative and tailored solutions to the construction industry’s most challenging projects.
