Engineering litigation is rarely about who is right or who has been wronged. It is mostly about which side develops and secures a winning line of argument that will, at worst, persuade a ruling body to settle the litigation in their favour or, at best, dissuade the other side from proceeding with the litigation. It rarely proceeds without some doubt in the case evidence. The settlement of this doubt requires the judgement of a ruling body. Expert witnesses can add substance and credibility to the formalised litigation drama. This book provides a unique sourcebook for expert witness and underwriters in engineering litigation of a range of case examples that can be used to plan their future litigation work and to help them develop their own winning lines of arguments. These examples are based on the authors 30-year experience in engineering litigation and include. Students in forensic engineering and risk engineering will find the books cross-displinary approach an ideal introduction to the subject.
