Ewan Slight Featured in The Voice of Foil

Hawkins is delighted to announce that Ewan Slight, Principal Associate and Chartered Quantity Surveyor, has been featured in the latest edition of The Voice of FOIL (Forum of Insurance Lawyers) Magazine.

In his article System Dynamics: An Alternative Approach to Construction Claims, Ewan explores one of the industry’s most persistent challenges: accurately evidencing productivity loss caused by disruption. Despite widespread use, traditional approaches, such as ‘global claims’ and ‘measured mile’ analysis, often struggle to demonstrate clear cause-and-effect relationships. Ewan explains why these methods can fall short, highlighting issues such as weak causal linkage, difficulties identifying unimpacted baselines, and problems with concurrency.

System Dynamics (SD) is a modern and technically robust approach for assessing construction disruption claims. By modelling construction projects as interconnected systems, SD captures cumulative impacts, feedback loops and non-linear interactions that traditional forensic methods may overlook. Through tools such as Causal Loop Diagrams and Stock & Flow modelling, SD provides transparent, data-driven simulations that demonstrate how disruption develops over time.

Ewan emphasises that System Dynamics offers significant advantages for dispute resolution, including improved quantum validation, greater evidential robustness for litigation or arbitration, and deeper portfolio-level risk insights. Its methodology is also aligned with the Society of Construction Law Delay Protocol.

Ewan is a Chartered Quantity Surveyor with more than 30 years’ experience in the construction and infrastructure sectors. He specialises in quantum analysis, delay, and disruption within major and complex disputes, and has held roles ranging from equity director to independent expert. Ewan is a RICS Registered Expert Witness, with experience delivering expert opinion and responding to adversarial questioning during pre‑hearing proceedings. By integrating quantum expertise, forensic delay techniques, and dynamic disruption modelling, Ewan provides robust, defensible evidence for litigation and arbitration. His work supports clients and legal teams by bringing analytical clarity, evidential rigour, and sound professional judgement to complex disputes.
