Any underground works have significant risks attached to them. Errors, failures of communication, and lack of adequate information can all add to these risks leading to problems in construction or in service of the assets. Responsibility for these shortcomings is often unclear and the subject of claims, arbitration and litigation.

Protagonists in such actions need clear, impartial expert engineering advice delivered with integrity and the strength of real experience. This supports the legal teams in evaluating the facts and information available and in creating a legal case to pursue. This advice must come from experts unconnected with the project that is the subject of the action.

Jason Consultants’ senior Associates and Principals have extensive experience in providing such expert witness advice and support. This experience encompasses complex failures of projects in several regions of the world, as well as expert opinion in patent infringement and similar intellectual property actions. This includes depositions under oath and courtroom testimony under cross-examination.

Our expert input has helped legal teams to build their own cases, identify flaws in opponents’ cases, and to understand the fundamental strengths and weaknesses of their positions. We work in a team with counsel and provide clear and impartial advice based on our expertise. We do not compromise our integrity by offering biased advice that suits a lawyer’s or client’s argument but is not supported by facts or knowledge. To do so is not tenable and eventually undermines the client’s position.
