Acceleration issues are amongst the most complex problems facing the construction industry. They present legal, technical and practical difficulties which can impact significantly on the risks and cost profile of a project. The subject raises a number of important issues – instructed acceleration versus constructive acceleration; what constitutes true constructive acceleration; the practical situations in which acceleration issues arise and the dilemmas they present; whether the Singapore standard form contracts provide any assistance; the conceptual and practical overlap between constructive acceleration and mitigation; the approach and analysis of the case law and the technical aspects of demonstrating and proving the effect of acceleration. In this seminar, we draw on the experience of two distinguished speakers who will discuss these and other aspects of this intriguing subject.
