Expert witness

Independent hydraulic opinion when a system is in dispute

Forensic review of building hydraulic services: what was designed, what was installed, and whether it could reasonably have performed. Written so lawyers, insurers and tribunals can use it.

Expert witness work is a separate lane from design commissions. The job is an independent opinion, not advocacy for a preferred outcome. If we cannot support a position from the facts and the applicable standards, we will say so before you brief further.

Typical instructions include defect investigations, alleged design or installation failures, and reports for legal teams. Conferral and oral evidence can be arranged where the matter needs it.

What to send with an instruction

  • Drawings, specifications and any revisions
  • Photographs, site notes and as-installed information
  • The questions you want answered
  • Programme and any court or tribunal dates
