HKA Experts will (try to) demystify delay analysis and the corresponding prolongations costs by way of two presentations and (hopefully) an engaging Q&A session.

Delay presentation by Dimitrios Tousiakis will provide a practical guide to the common delay analysis methods and focus on the differences between the Retrospective Critical Path and the Contemporaneous Critical Path.

Quantum presentation by Igor Corelj will explain why the critical path matters in terms of money and the quantum tricks behind deriving the appropriate daily rate of prolongation costs.

Michael Tonkin will be moderating the event by engaging the audience with Q&A session. HKA welcomes questions before, during and after the event.

19:15 – Presentation starts
