Case Study

Sector: Infrastructure (Roads)
Location: NSW
Client: Confidential
Project Value: Multi-billion (AUD)

• Background

  A complex underground road interchange formed part of a larger city-shaping motorway. Multiple contractors worked under pressure to deliver within ambitious timeframes.

• Challenge

  Scope creep, shifting design requirements, and interface issues across multiple parties caused disputes over time and cost entitlements. Documentation was fragmented and the client faced mounting payment delays.

• Our Approach

  Conducted a forensic review of records, contracts, and statutory entitlements.

  Structured claims using a cause–effect–quantum framework.

  Provided independent peer review to strengthen submissions.

• Solution implemented

  Developed robust claim documentation and adjudication submissions aligned with both contract and statutory requirements.

• Results

  Developed robust claim documentation and adjudication submissions aligned with both contract and statutory requirements

• Key Takeaways

  Disciplined record-keeping and structured claims are critical in multi-party infrastructure projects.

  Independent review of entitlements reduces risk of rejection.
