Quantum & Disruption

Quantum & Disruption

Our Quantum and Disruption team provide independent, tribunal-ready expert services for the construction, energy and infrastructure sectors. We specialise in the forensic analysis, valuation and presentation of expert submissions arising from complex, high-value projects across among others oil & gas, offshore, onshore and floating wind farms, solar farms, transport, utilities, energy, process, residential commercial development, data centres and public infrastructure.

We establish the clear financial consequences of delay, disruption, acceleration, change, prolonged performance and termination and are regularly appointed to analyse and quantify claims and counterclaims, test competing expert opinions and deliver clear, objective evidence on quantum and financial causation.

Our experts act across all major dispute resolution forums, including litigation, arbitration, adjudication, dispute adjudication boards (DAB), mediation and expert determination.

Typical instructions include:

• Forensic Cost Analysis: Detailed examination of project cost to identify cost variances
• Causation Analysis: Assess the root causes of cost variances and support legal professionals in evaluating liability
• Forensic Investigation: Rigorous analysis of project records to establish a robust factual basis for evidence-based opinions to enable better decision making for clients
• Project Cost Forecasting: Calculation of project completion costs under varying scenarios based on evidence 
• Dispute Avoidance & Resolution Strategy: Development of strategies to prevent disputes and manage cost submissions/ claims efficiently, including case management
• Rectification of defects: Work closely with technical and planning experts to establish or estimate the cost associated with technical proposals to rectify defects
• Loss and Expense claims including prolongation, disruption, acceleration: Quantification and assessment of extended site preliminaries (site management, supervision, welfare, plant, etc.), head office overhead recovery, additional labour, plant, or materials, inefficiency and productivity loss, acceleration costs, finance charges or increased cost of working, etc.

• Variations, change management and final account disputes: Evaluation of the entitlements associated with these issues
• Termination, suspension and insolvency-related losses: Evaluation of the cost associated with these issues
• Measurement of damages arising from breach of contract: Evaluation of damages arising from a breach of contract
• Support in Amicable Settlement Proceedings: Assistance in negotiations and settlement discussion to achieve favourable outcomes
• Forensic review and rebuttal of opposing quantum reports: Critical analysis and rebuttal of opposing independent expert or claims reports
• Training & Presentations: Tailored workshops and presentation on quantum analysis, claims management and dispute resolution

We combine deep sector knowledge in construction, energy and infrastructure delivery with quantity surveying, commercial management, cost engineering, construction management, programme integration and contract interpretation to ensure that our opinions are technically sound, contractually grounded and commercially credible.

Above all, we are known for our independence, clarity and resilience under cross-examination, delivering expert evidence that assists tribunals in reaching fair, reasoned and well-supported decisions on quantum. We focus on practical and pragmatic solutions and opinions, and consciously avoid theoretical possibilities.

Our Disruption & Quantum Methodologies

We apply rigorous, recognised methodologies selected to suit the nature of each dispute, the quality of records available and the applicable legal and contractual framework. Our approach is evidence-led, transparent and fully explainable before a tribunal, legal team and clients.

Typical methodologies include:

• Prolongation Cost Analysis – time-related cost recovery
• Disruption and Inefficiency Modelling – labour and resource impact
• Measured Mile Analysis – for productivity and disruption assessment
• Total Cost and Modified Total Cost Analysis – where records require it
• Acceleration Cost Evaluation – instructed and constructive acceleration
• Change and Variation Valuation – contract-based measurement
• Termination and Final Account Valuation – including re-procurement losses

All opinions are supported by contemporaneous project records, cost data, programmes, site reports and commercial documentation. We clearly separate entitlement, causation and quantum to ensure analytical integrity and legal robustness.
