Where additional work is required (beyond the scope of the tender) the parties must agree to proceed …. Such work will generally require amendment to the programme and result in additional costs. Consider:

– What is the progress of the works when additional work is proposed?
– Is the work on programme?
– Is the contractor’s work of the specified quality?
