Sam Wallis

Sam Wallis qualified in 2015 and is a principal associate in Gowling WLG's contentious construction team. He helps clients avoid or resolve their construction disputes. Sam has a particular interest in matters concerning fire safety and cladding.

Sam enjoys getting to grips with the construction and engineering aspects of a dispute in order to work out exactly what went wrong and why. He knows every dispute is unique and involves many stakeholders with different drivers. He seeks to understand these drivers to better inform the case strategy. He always takes a pragmatic approach and explains the complexities of construction law in a simple and well-structured way.

Sam likes to draft a clear case plan at the outset to ensure clients are aware of the potential directions, risks, costs and timing of a dispute. He is experienced in a number of different dispute resolution methods including arbitration, litigation and mediation. Sam has led a number of major disclosure exercises and has practical experience of the Disclosure Pilot Scheme (introduced on 1 January 2019) which applies to cases in the Technology and Construction Court. Sam also has significant experience of working with experts and witnesses to prepare evidence for hearings. He believes in meeting with clients face to face where possible which is so easy not to do in this age of technology. Sam's main objective is to achieve the best commercial result for your business.
