An agreement made under clause 36 on acceleration would have the effect of bringing the completion date forward to an earlier date than it currently is. This is different to the contractor accelerating its work to advance the date by which it expects to achieve completion. The contractor should be motivated to want to achieve completion on or before the completion date to avoid being in breach of clause 30.1 and liable for any delay damages as a result.
If the completion date is moved forward to an earlier date, then all obligations and actions linked to this date will be moved to the earlier date. If secondary option X6 has been selected, any bonus payable to the contractor will only be applicable if the contractor achieves completion before the revised completion date. Damages for delay will also be applicable from the revised completion date.
