This chapter discusses delay and the resulting claims and disputes are most usually dealt with through specific contract provisions which also provide a method for their resolution, e.g. dispute boards, arbitration, etc., and certain types of delay are also excused, and for what remains, it then falls to either the employer or the contactor to bear the burden of any particular form of delay. The real goal however is to manage potential delay issues during the works themselves so that they are resolved to everyone’s satisfaction. The term “claim” is defined in the context of construction projects as any application by the contractor, whether for an extension of time, payment. A mistake which is often made has to do with the idea that a delay event is a simple matter, and one only has to trace the days lost or attributable to the event to come up with an answer.
