Corexus is a specialist forensic delay and construction and engineering disputes practice built around quality, precision and clear expert judgement. Led by Louk Korovesis, a multilingual testifying delay expert with nearly 20 years of construction and consulting experience, the practice supports complex matters in arbitration, Dispute Boards (DAB), adjudication, mediation and negotiation.
