Answered: NEC ECC: Discrepancy between Bill of Quantities and Works Information in Option B

Broadly speaking yes it would be a CE. Clause 60.7 states that a compensation event resulting from a correction of an inconsistency between the BofQ and another document (i.e. Works Information) - the Contractor is deemed to have taken the BofQ as correct.

Errors in the B of Q are generally intended to be Employer risk under option B.
