An expert witness is a person with a depth of knowledge of the building industry, regulations, Codes and requirements to build and complete a structure to an acceptable standard.
An expert is one who has been in the building industry for many years and understands the complexity of the industry and is able to separate client expectations from the requirements of various building standards. That expert is to draw on the years within the industry, provide reference to the required standard and where required, provide solutions.
The building expert will not be drawn into emotional or unsubstantiated claims and will only deal with matters of fact that are relevant to a claim or she can substantiate as a result of thorough investigation. The expert must show all documentation that has been used to arrive at a conclusion, dispute or matter at hand.
