We are carrying out an Option A contract. Our Client de-scoped some works and asked for a cost saving. The saving offered was calculated in error and the sum/value that the clients PM has accepted, is substantially more than that of the activities value in the activity schedule.
Is there a clause in the NEC contract which allows the Contractor to retract the quoted clients cost saving (after the clients P.M has accepted the quote) when it is clear that the contractor has made an error?
Should the PM have accepted the quote or does the PM have a responsibility to allow the Contractor to revise the cost saving quote when it has been highlighted that there has been an error?
