NEC3 ECC Option C
An event occurred that introduced a CE (referred to as CE100) which has both a time and cost impact. A quotation was instructed at the time the CE was notified. No EWN proceeded the CE.
At the time of instructing a quotation for CE100, there was an Accepted Programme
(Referred to as AP10)
The subject matter is complex and it has taken the Contractor some time to assess the impact of the change, requiring the PM to grant an extension to the period for response.
In the meantime, a new programme has been submitted by the Contractor for acceptance, which has now been accepted by the PM as the Accepted Programme referred to as AP11). The Accepted Programme AP11 did not include any assessment of the effect of the impact CE100 on Planned Completion.
Which programme should the effect of CE100 be based upon? The Accepted Programme AP10 at the time the quotation for CE100 was instructed? Or, the current Accepted Programme AP11?
