Solvix International provides expert witness testimony services for construction and engineering disputes where independent technical opinion is needed to explain programme, cost, valuation, causation, design, workmanship, or project-performance issues. We work with counsel, claim teams, funders, insurers, employers, contractors, and subcontractors to turn complex records into clear expert opinion that can withstand scrutiny in adjudication, arbitration, litigation, or other formal dispute forums.
Our role is not simply to restate a party position. We assess the record independently, apply a defensible methodology, identify assumptions and limitations openly, and present conclusions in a way that is understandable to decision-makers who may not be specialists in delay analysis, quantum, or construction engineering.

Opinion on critical path, event chronology, concurrency, time impact, progress records, and schedule causation.
Opinion on valuation, prolongation, disruption cost, damages, payment records, and cost causation.
Opinion on engineering issues, defects, compliance, design performance, failure mechanisms, and responsibility.
Although every dispute is different, expert evidence usually sits within one or more of three evidence streams: time, money, and technical causation. Solvix structures the engagement around the actual issues in dispute, the forum timetable, and the standard of analysis required for the report and any rebuttal stage.
An expert report is written for the tribunal, not for the instructing party. It should set out the questions, the evidence relied on, the method used, and an opinion that the expert can explain and defend under cross-examination.
The opinion is the expert's own and is reached on the evidence, regardless of which party gives the instruction.
The route from the records to the conclusion is explained so that it can be tested and repeated.
Findings are presented so that non-specialist readers can follow the reasoning and the key figures.

In many construction disputes, the challenge is not simply the absence of data but the absence of structure. Critical information is spread across correspondence, schedules, notices, progress updates, payment records, meeting minutes, instructions, and technical documents. Solvix helps turn that fragmented material into a disciplined narrative and evidence base that legal teams can work with effectively.

Support preliminary review of the project history, central dispute themes, probable strengths, and obvious weaknesses in the record.
Assist with structuring the factual narrative, identifying missing evidence, and testing whether the position advanced is consistent with the documents.
Help organise issue-based material that can inform particulars, responses, expert instructions, or technical annexures.
Analyse the opposing position, identify gaps or inconsistencies, and prepare structured response points or rebuttal inputs.
Coordinate analysis assumptions, chronology references, and documentary cross-checking between technical teams and legal representatives.
Support the preparation of hearing notes, key-date packs, demonstrative material, and final quality checks on referenced records.
A disciplined workflow from instruction through hearing support
Core elements usually expected in independent construction expert reporting
Define the question, scope, and assumptions.
Show the records and data relied upon.
Explain how the analysis was performed.
Set out the material results and observations.
State the conclusion clearly and independently.
The exact evidence bundle varies by case. In some matters the programme record is central; in others the key issue may be payment valuation, defective design, specification compliance, or reconstruction of causation from incomplete records. Solvix works with the available evidence while identifying gaps and document risk early.
A delay expert is needed to evaluate the opposing party’s programme case or to prepare a formal expert report on time entitlement and causation.
A quantum expert is needed to explain valuation, prolongation, disruption, or damages in a way that links cost records to the alleged events.
A technical expert is needed to address design responsibility, defects, compliance, workmanship, or failure mechanism questions.
A claim consultant may help develop or defend a party position. An expert witness provides an independent opinion based on technical analysis and is typically instructed for a formal dispute context.
Yes. Depending on the dispute, Solvix can support one or multiple evidence streams, provided the scope is clearly defined and independence is preserved.
No. Early expert input often helps counsel and commercial teams test strengths, weaknesses, and evidential gaps well before the matter reaches a hearing.
Yes. Rebuttal review is a core part of expert support and can include critique of methodology, assumptions, calculations, chronology, and source records.
