Solvix International provides quantum analysis services for employers, contractors, subcontractors, developers, funders, project managers, commercial teams, and legal advisers who need a robust financial assessment of a construction or engineering claim. Our work focuses on translating project events, records, and contractual positions into a clear commercial valuation so decision-makers understand what is recoverable, what is overstated, and what evidence is required to support or challenge the claim.

Assess prolongation, disruption, variation, acceleration, termination, defects, and other loss-and-expense heads of claim using a method appropriate to the records and contract position.
Trace claimed sums back to project facts, cost ledgers, procurement records, labour and plant data, subcontract accounts, and contemporaneous instructions so the valuation is evidence-led rather than theoretical.
Align quantum findings with delay analysis, entitlement review, and dispute strategy so time, causation, liability, and cost positions work together rather than in isolation.
Quantum analysis is not limited to one type of claim. Depending on the project circumstances, we assess direct cost, time-related cost, indirect cost, overhead recovery, and associated commercial consequences arising from instructed change, delay, disruption, inefficiency, suspension, acceleration, termination, or remedial works.
Assessment of site overheads, supervision, preliminaries, extended plant, staff, temporary facilities, insurances, and other time-related cost associated with excusable or compensable delay events.
Evaluation of labour and resource inefficiency, reduced output, trade stacking, resequencing, fragmentation, and cumulative impact where the project events affected the cost of performing the work.
Assessment of overtime, additional shifts, supplementary crews, premium plant usage, resequencing measures, and other mitigation or acceleration expenditure incurred to protect milestones or completion.

Quantum disputes often turn less on whether costs were incurred than on whether they were caused by the events relied on, are correctly calculated, and are supported by records. We test each head of claim on those three points.

Assessment of time-related costs for the delay periods established in the time analysis.
Valuation of productivity loss using measured mile, earned value, or other suitable methods.
Review of the valuation rules in the contract and of the rates and quantities applied.
Assessment of instructed or constructive acceleration costs and their link to the events relied on.
Review of formula-based and actual-cost approaches to overhead and profit recovery.
Valuation of sums due on termination, including completion costs and defects deductions.
The strength of a quantum opinion depends on method, evidence, and consistency. Our approach is designed to test what the contract permits, what the records actually show, and how the valuation should be presented so it can withstand commercial scrutiny.
We begin by defining the claim heads, relevant contract mechanisms, the period or work packages affected, and the precise question to be answered. This prevents the analysis from drifting into a broad cost review when the real issue may be a focused entitlement and valuation dispute.
We review contemporaneous records to understand whether claimed cost consequences can genuinely be linked to the events alleged. This includes instructions, notices, schedules, progress records, procurement data, time sheets, payroll, plant logs, subcontract accounts, invoices, ledgers, and payment records.
We select a calculation basis suited to the evidence and contract context. Depending on the issue, this may involve direct cost build-up, measured or actual cost review, rate analysis, allocation testing, time-related cost modelling, or comparison against budgets, tenders, or unaffected performance.
We test reasonableness, avoid duplication, challenge unsupported uplifts, and reconcile the figures across source documents. Particular attention is given to mitigation, overlap between claim heads, entitlement assumptions, and whether the claim seeks recovery of items that are already absorbed elsewhere.
The final step is to present the quantum position in a way that is technically sound and commercially useful. We prepare reports, schedules of quantum, explanatory narratives, sensitivity testing, and rebuttal points that can be used in submissions, assessments, negotiation, ADR, arbitration, or litigation support.
| Commercial and Contract Records | Contract conditions, amendments, BOQs, rates, variation quotations, correspondence, notices, payment certificates, cost reports, applications, and assessments. |
| Project Execution Records | Baseline and update programmes, progress reports, site diaries, instructions, RFIs, design releases, method statements, productivity records, daily allocation sheets, and meeting minutes. |
| Cost Support Records | General ledger extracts, cost codes, invoices, payroll, plant logs, hire records, material purchase orders, delivery notes, subcontract accounts, and internal allocation schedules. |
| Claim and Dispute Records | Claim submissions, rebuttals, expert materials, settlement positions, adjudication or arbitration pleadings, and any prior determinations that shape the valuation framework. |
Quantum analysis is most valuable when a project team needs clarity before positions harden, but it is equally effective when a dispute is already underway and the cost case must be tested rigorously.
Build a credible, evidence-supported valuation before submitting a prolongation, loss and expense, disruption, variation, acceleration, or damages claim.
Test whether an incoming claim is adequately evidenced, methodologically sound, contractually recoverable, and free from duplication or unsupported assumptions.
Use a clear, well-structured quantum position to support without-prejudice negotiations, mediation, conciliation, or executive settlement discussions.
Prepare quantum reports and schedules suitable for adjudication, arbitration, litigation support, or integration with independent expert and legal workstreams.
Identify cost leakage early, clarify the commercial impact of live events, and support better decision-making before the dispute exposure escalates.
Quantum analysis is the financial and commercial assessment of the sums said to arise from project events. It addresses how much is being claimed, how that figure is derived, whether the valuation is supportable, and whether the claimed items are properly linked to entitlement and causation.
Delay analysis focuses on time and programme effect, such as impact on completion, milestones, and the critical path. Quantum analysis focuses on cost and damages, such as prolongation, loss and expense, disruption cost, change valuation, overhead recovery, and related commercial consequences. The two disciplines often need to work together.
Yes. Part of our role is to assess whether the available evidence is sufficient for a reliable valuation and to identify what additional support would materially improve the position. Where records are limited, we make the evidential gaps visible so the client understands the strength and limits of the claim or defence.
Yes. We support affirmative claim preparation as well as claim defence and evaluation. The underlying discipline is the same: identify the facts, test recoverability, challenge unsupported assumptions, and present a balanced valuation that can withstand scrutiny.
Yes. Quantum analysis can feed directly into negotiation, mediation, adjudication, arbitration, and litigation support. Where required, the work can also be aligned with wider dispute strategy and independent expert processes.
