WHAT WE PROVIDE

Independent expert witness support for complex construction disputes

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.

CORE DISCIPLINES

How expert witness testimony is typically framed

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.

  • Pleadings, statements of case, claim submissions, and responses
  • Programmes, updates, progress reports, diaries, and delay-event records
  • Cost reports, payment applications, valuations, invoices, and ledgers
  • Technical drawings, specifications, inspection records, and test data
  • Correspondence, meeting minutes, expert reports, and witness statements

Typical deliverables
