Project Overview

TAG Advisory was engaged by Main Roads Western Australia (Main Roads) to assist in the resolution of complex claims submitted by the contractor on the Chidlow - York Road regional upgrade project. The engagement focused on providing independent expert advice on matters of time and quantum, supporting Main Roads in navigating significant commercial disputes that had emerged during this important regional road infrastructure improvement project.

Key Challenges

The project encountered substantial commercial complexity with the contractor submitting multiple intricate claims covering both time extensions and cost variations. These claims required detailed forensic analysis to determine validity, causation and appropriate entitlement under the contract conditions. The technical nature of the claims demanded deep understanding of civil construction methodology, programming and cost build-up in regional delivery contexts.

Regional project delivery added layers of complexity including weather impacts, resource availability constraints, material supply logistics and site access challenges specific to the Chidlow - York Road corridor. These factors required careful consideration when assessing the legitimacy and quantum of contractor claims against baseline obligations.

Methodology and Approach

TAG Advisory implemented a systematic approach to claims assessment, combining technical analysis with commercial and contractual expertise. The review process encompassed comprehensive examination of project documentation including programmes, correspondence, site records and cost substantiation.

For time-related claims, the team conducted:

• Critical path analysis and delay assessment
• Evaluation of concurrent delays and contractor culpability
• Extension of time entitlement verification
• Programme logic and sequencing review
• Weather and force majeure impact assessment

Quantum assessment involved:

• Analysis of claimed rates against contract provisions
• Assessment of productivity impacts and measured mile analysis
• Detailed review of cost substantiation documentation
• Evaluation of preliminary and general items
• Review of disruption and prolongation costs
• Verification of actual costs against claimed amounts

The team maintained independence whilst working collaboratively with Main Roads' project team to understand project history and technical complexities.

Outcomes and Value

TAG Advisory's independent assessment provided Main Roads with robust, defensible positions for claims negotiation. Clear analysis distinguishing legitimate entitlements from ambit claims enabled focused commercial discussions and efficient dispute resolution. The structured approach to time and cost assessment established factual foundations that supported successful commercial outcomes.

Expert advice on quantum matters enabled Main Roads to avoid overpayment whilst recognising legitimate contractor entitlements, maintaining commercial relationships and project momentum. The comprehensive documentation and analysis provided by TAG Advisory created an audit trail supporting Main Roads' commercial decisions and protecting the State's interests.

Conclusion

The Chidlow - York Road engagement showcased TAG Advisory's expertise in complex claims resolution for regional infrastructure projects. By providing independent, technically robust advice on time and quantum matters, TAG Advisory enabled Main Roads to achieve fair commercial outcomes whilst protecting public value. This engagement reinforces TAG Advisory's capability in dispute resolution and commercial management for challenging regional road projects.
