Claims for “delay and disruption” represent a common feature of construction disputes.[1]

The first requirement for presentation of any claim is a proper analysis of facts. There is a natural and traditional tendency in relation to delay and disruption claims to assume that the task is impossible, and therefore, to avoid even trying to make a proper analysis.[2]

Delay events are significant issues in construction projects. Delays in the construction industry often refer to multiple aspects, defining the entire project and putting various obstacles in the way of agreed completion dates.

In this seminar, we will explore basic concepts of delay analysis to understand better a practice that is sometimes referred to as a “dark art”.[3]

The session aims to assist lawyers, in-house counsel, project managers, planners/schedulers, and contractors by clarifying the basic concepts and how delay analysis can support the submission of delay and disruption claims.

The session will cover the following main topics:

  • Short introduction on delay analysis.
  • The concept of critical path: basic principles and identifying critical paths.
  • The critical path and longest path concepts.
  • The concept of critical delay and categories of critical delays.
  • Prospective vs retrospective delay analysis methodologies.
  • How to read a programme of works.
  • How counsel can avoid situations where the delay experts provide different opinions on the same matter.
