Clarity in Complexity
Expert witness and claims consulting for Australia’s most complex construction and infrastructure projects. Led by a Chartered Quantity Surveyor & Quantum Expert, we deliver compelling narratives for quantum assessment and claims strategy, grounded in rigorous, evidence-based analysis and over 30 years of hands-on project delivery experience.
Our Core Expertise
Evidence-Based Chronology & Fact-Finding
Our process begins with a forensic deep-dive into contemporary project records. Leveraging advanced analytical tools, we reconstruct the sequence of events to build a clear, evidence-based chronology—the foundation for any successful claim or expert report.
Winning Claim Strategy & Formulation
We develop and write compelling claim strategies that integrate commercial, technical, and legal considerations. The result is a robust, evidence-based argument built to survive the scrutiny of the dispute process.
Forensic Quantification of Damages & Costs
We provide an objective assessment of project costs, variations, and disruption damages. We move beyond simple arithmetic to establish the clear link between site events and financial outcomes.
Escalation & Indexation Analysis
We provide specialist quantification of cost increases resulting from hyper-escalation and changes to industrial relations instruments. We apply forensic cost modelling to identify price movements relative to tender allowances, utilising information published by the ABS, the Fair Work Commission and relevant industry bodies.
Strategic Dispute Resolution
We provide senior-level strategic advice to support clients in arbitration, adjudication, and expert determination proceedings. We deliver pragmatic insights to legal teams and executives, ensuring informed decision-making early in the dispute lifecycle.
Independent Expert Reports
The culmination of our work is the delivery of clear, objective, and authoritative expert reports for formal dispute resolution proceedings. We provide independent testimony designed to withstand the highest levels of scrutiny in litigation and adjudication.
An Engineer’s Perspective on Commercial Disputes
With a career spanning three decades – from a degree-qualified Civil Engineer and Quantity Surveyor to a Project Director on multi-billion dollar projects – Jeff Cheema brings a level of practical, on-site experience that is exceptionally rare in the consulting world. This allows Spier Services to deliver analysis that is not just commercially astute, but technically sound and grounded in the reality of how complex projects are built.

Our Approach
Our methodology is built on a forensic, evidence-based approach that prioritises facts over assumptions. We analyse challenges from two critical viewpoints: the on-site team’s delivery requirements and the commercial drivers of the contract. This unique, 360-degree view allows us to identify the true root cause of cost damages and build compelling, undeniable narratives.
