This Practice Note provides a summary of the different methods of delay analysis commonly used, and the key terminology that arises. It follows the approach taken in the second edition of the Society of Construction Law Delay and Disruption Protocol (SCL Protocol), at guidance section 11. For more information on the SCL Protocol, see Practice Note: Delay and disruption in construction projects—The Society of Construction Law Delay and Disruption Protocol.
