Jean-Bernard Dehaut practises civil and commercial litigation. He is a member of the Construction and Infrastructure group, acting primarily in the dispute prevention and resolution area (adjudication, mediation, arbitration, courts of law and standard-setting bodies), including issues surrounding requests for the adjustment of timetables and financial terms, non-compliance and defects arising during construction and warranty periods, issues arising during calls for tenders, legal hypothecs, sureties, insurance, insolvency, intellectual property and job-site health and safety.

Jean-Bernard also focuses on issues related to compliance with standards imposed by the Régie du bâtiment and the Commission de la construction du Québec. In addition, he holds a Restricted Appearance Certificate allowing him to act in certain files in Nunavut.

He regularly gives conference presentations on subjects of interest in the field of construction and infrastructure, particularly contract drafting and the price of materials.

Jean-Bernard is always attentive to his clients and handles their files efficiently and expeditiously. He strives to prevent litigation that could arise from disputes.
