OK three questions in one, so here goes:
1) Contractor is paid in line with completed items on their activity schedule. Fact it is or is not on their programme is kind of irrelevant. If the activity schedule does not include for that stretch of fencing then they will not be paid specifically for it, yet have to provide it if it was in the Works Information at tender stage.
2)If the alternative piling solution meets the Works Information then there is no reason not to go with that and the Contractor would benefit from the value engineering if it is an idea they have come up with for something that is their design responsibility (see exception within 60.1(1)). If however it may be a bit subjective if it complies with Works Information I would get Project Manager buy in that this solution everyone is happy with.
3) and finally, Contractor can provide a revised activity schedule for acceptance if the Contractor changes a planned method of working that means the activity schedule no longer reflects the operations on the Accepted Programme(54.2). The PM should accept that revised activity schedule, unless it is not in line with accepted programme, or does not reflect the total of prices, or costs are not evenly distributed.
