Our Record

We have served as expert witness in thermal engineering topics across England, Wales, Scotland & the United States since 1998, also providing forensic services for HVAC systems, process plant and heat transfer equipment. Where practicable, we act as Single Joint Witness under the Civil Procedure Rules - CPR - which stress the primary duty of an expert as being to the Court. In any event, we may be relied upon to give accurate technical advice. Not all our commissions are necessarily intended for formal litigation supported by the expert witness process. We have a strong record in ADR, independently or with instructing solicitors, and most of our cases are settled out-of-court to general benefit and satisfaction.

A Singular Instance

Whilst other pages in the website report examples of our forensic and general consultancy work, the following case demonstrates how we have acted as expert witness for heating topics , and illustrates our practical approach to the process. It was also remarkable for failures at each stage of the resourcing chain:

The Environment Agency had been called in response to complaints of excessive vapour plume emission from the exhaust stack of a shell & tube boiler, fired by wood waste from the furniture factory where it was installed. The system was losing water, although visual inspections had showed no defect. Our investigation proved this to result from the boiler having been built using faulty tubes: the seam welder had "missed" a significant length of run as the formed section passed through the mill. Notedly, inspections at tubemill, stockholder, converter and the boiler manufacturer had all passed unremarked. The affected tubes sprang apart when cut through, as shown in the photo. Summary Judgment was obtained and applied.

Given extensive research, development and applications experience of evaporative systems, we have provided cooling system expert witness services - directly and indirectly associated with plant performance - including outbreaks of Legionnaires’ Disease at a high-profile inner city industrial site.
