NEC4 Option C Contract including X15 ‘Contractors Design’ with two relevant additional compensation events within Contract:
• Utility performance (risk item) will be measured against stated notification periods and works durations within the C4 quotations. Any durations in excess of the stated notification periods will be a client risk and Compensation Event.
• All C3/C4 utility payments have been excluded from the tender and will be covered by other contracts or a Compensation Event.
The Contractor comes across known utilities (shown on GPR survey and surveyed via trial holes at the design stage), which now need diversions. These utilities weren’t identified for diversion at the design stage (validated by the Contractor in their design).
Is this a valid CE under the additional compensation events? If yes, would it include C4 cost only?
