A Pragmatic Approach to Delay Analysis: Lessons from White Constructions v PBS Holdings
If delay experts come to different conclusions regarding the quantum of time in delay, analysis methodology may have dictated the outcome, as White v PBS demonstrates.
What date is your price? The question rectification reports often leave out

How to Build Up an m² Rate: Insights from a Forensic Quantity Surveyor and Quantum Expert Witness

Why an As-Built Programme Is the Most Underrated Document on Any Project
The As-built programme may be the most underrated document on any project for delay experts. A vital record of what really happened, activity by activity, as the project unfolded.
Why Courts Do Not Require Perfect Proof of Prolongation Costs
The strongest prolongation claims are not necessarily those supported by the largest volume of records. Delay experts build the strongest claims with an evidentiary pathway that is clear, logical and capable of being tested.
V601 Developments v Probuild: Time vs Cost
V601 Developments v Probuild confirms that delay and disruption must be proven independently. Disruption techniques can suggest loss, but only a forensic QS and quantum expert can show cause and cost with evidence.
Disruption is not an Entitlement, rather it is the Cost Consequence of Change
For quantum experts, CPB Contractors v Transport for NSW completes the progression from Kvaerner to Probuild. It confirms that inefficiency is not a separate claim. It is the cost consequence of change.

In construction claims, delay and disruption are different things. Delay is about time. Disruption is about cost. The two demand different evidence from experienced quantum expert witness and delay expert witness.
Why Retrospective Delay Analysis Carries Weight
Prospective methods are useful during delivery but once the work is complete, those models compete with actual events and, that’s where retrospective methods take precedence.
Prolongation Costs: Costain v Haswell and How It Reads in Australia
Melbourne and Brisbane delay and quantum experts examine prolongation costs, Costain v Haswell and what Australian construction disputes can learn from the decision.
Courts Don’t Buy Global Claims. Nor Should QS Experts.
The case of John Holland Construction & Engineering Pty Ltd v Kvaerner R J Brown Pty Ltd remains one of the earliest and most important Australian warnings against “rolled-up” or “global” claims for quantum experts to consider.
The Steps an Expert Must Take When Analysing and Opining on Disruption Claims
The decision in Santos Limited v Fluor Australia Pty Ltd does more than explain what disruption is. It shows, in practical terms, how a disruption claim must be analysed and proven.
The Discretionary EOT Clause Nobody Reads Until It's Too Late
Most EOT clauses are read as hurdles but there’s one that is often missed, and it gives the principal or head contractor a discretionary power to grant an EOT even where no valid claim has been made at all.
