Case Studies & Lessons Learned

The following case studies present examples where law firms engaged Albert Merolla as a Quantum Expert Witness. Each outlines the context of the dispute, the approach taken, and the outcome achieved.

Urban Rail Project –
Change Process Misuse

Urban Rail Project – Change Process Misuse

On a major urban rail EPC, a 540-day delay claim blamed Employer Change Notices, but forensic analysis showed the real driver was replacing the original design house and misusing the contractual change process. Mapping 36 CNs to the critical path reframed the dispute around internal design and process failures, not cumulative change. Read more.

Warehouse Automation -
Delivery-Model Misalignment

Warehouse Automation – Delivery-Model Misalignment

A principal technology provider’s standard teaming model was undermined when a newcomer package was let on conventional lump-sum terms. Misaligned contract and site controls led to disputes, underscoring lessons on briefing teams, supporting PMs commercially, and managing any departures from the agreed delivery model. Read more.

Wind Farm Electrical –
As-Built Misalignment

Wind Farm Electrical – As-Built Misalignment

On a large wind farm, outdated OEM manuals and pre-wired turbine masts clashed with site conditions, driving significant re-wiring and access impacts. Mapping manual versus as-built conditions enabled hour-based valuation of variations and reinforced early treatment of documentation-driven change. Read more.

No initial discussion should be taken as an acceptance of instructions or the formation of a commercial relationship.

What Is a Quantum Expert Witness?

In construction and infrastructure disputes, quantum refers to the financial value of a claim — the measurable cost of loss, delay, or variation. A Quantum Expert Witness is an independent professional who analyses that value objectively and explains it to a court, tribunal, or arbitrator.

The role centres on translating complex technical and commercial issues into clear, evidence-based financial conclusions. This evidence helps decision-makers understand how much an issue cost, why it cost that much, and whether those costs are justified.

Key Responsibilities of a Quantum Expert Witness

Assess the financial impact of delay, disruption, and variation claims
Review project records, cost data, and schedules to determine factual costs
Prepare independent expert reports for litigation, arbitration, or adjudication
Provide objective evidence based on recognised valuation methodologies
Assist the court or tribunal in understanding the link between project events and cost outcomes

A credible Quantum Expert Witness must combine technical expertise with financial acumen. With over 30 years of experience, Albert Merolla bridges both through his dual qualifications as a Chartered Engineer (CIBSE) and Chartered Quantity Surveyor (RICS). His reports integrate engineering precision with commercial reasoning — ensuring the financial evidence is defensible and transparent.

What Does a Quantum Expert Witness Do?

A Quantum Expert Witness investigates the financial side of a construction dispute, analysing what occurred, what it cost, and whether the costs claimed align with contractual entitlements.

This process involves methodical examination of data and an ability to communicate findings clearly for legal and non-technical audiences. Albert Merolla’s role often includes reviewing variations, identifying cost causation, and explaining how certain project events affected time and budget.

Typical Tasks of a Quantum Expert Witness

        
                Task

                Report Preparation
                Produces clear, independent expert reports in line with court or arbitration requirements.

Loss and expense calculations
Productivity and performance analysis

Albert’s expert reports are prepared using recognised techniques such as measured-mile analysis, earned value, and cost-to-complete assessments. This ensures that each conclusion is grounded in evidence and withstands technical and legal scrutiny.

When to Engage a Quantum Expert Witness

Engaging a Quantum Expert Witness early can help law firms control risk and shape case strategy with accurate, defensible evidence. Waiting until late in proceedings can limit the ability to validate data or correct unsupported claims.

A quantum expert should be brought in whenever there is uncertainty about cost entitlement, causation, or valuation accuracy. Early collaboration between the legal team and the expert ensures that the evidence gathered supports both technical and contractual arguments.
