We are working on an ECC option A and I have a query concerning implemented CE’s.
The PM has implemented a CE and subsequently says there were errors in it, one of which was that the fee percentage was wrongly applied.
As the CE was implemented the PM has not re-opened it, rather they have deducted the difference from another unimplemented CE and implemented that one, as a PM’s assessment, at a lower value than that previously agreed - Which I do not agree is correct, as this CE should be valued on it’s own merits and should not be reduced for a previous error.
However would the PM be within their rights to adjusted the previously implemented CE for a calculation error and re-implemented it at a lower value, as clause 65.2 only refers to it not being changed if the forecast is wrong?
Is there also any guidance on when an option A contract should be used, as I thought it’s preferred use was when the project was fairly well designed and it was thought there would be minimal change.
The project we are working on has had in excess of 300 CE’s that are likely to increase the final value by 50% and we are being disallowed additional staff costs in dealing/pricing the CE’s.
Your thoughts on this would also be appreciated.
