When to consider

When an expert report may be needed

Where a construction dispute affects payment, valuation, delay, disruption or professional negligence, the recovery position depends on more than assertion.

An independent expert report helps turn disputed sums, records and technical issues into a structured opinion that can be used to pursue financial recovery, defend a claim, support settlement or prepare for adjudication, litigation, arbitration or mediation.

Typical disputes include:

  • Disputed valuations, variations or final account sums
  • Payment, retention, loss and expense or damages claims
  • Delay events, programme impact or critical path issues
  • Disruption, productivity loss or inefficient working
  • Professional negligence allegations involving valuation, certification, notices, payment assessment, final account handling or contract administration
  • Adjudication, litigation, arbitration, mediation, settlement or insurance-related claims
