According to the FIDIC Yellow Book 2017, the Commencement Date is the date notified by the Engineer as the date on which the Contractor shall start the execution of the Works (Sub-Clause 8.1). In this case, although the Engineer notified 15 July 2022 as the Commencement Date, it was subject to the issuance of the construction permit. Since the construction permit was only obtained on 1 August 2022, work could not legally commence before that date.

FIDIC recognizes that the Contractor cannot be expected to start before all necessary permissions are granted. Hence, the effective Commencement Date must be the earliest date on which the Contractor can legally commence work, i.e., the date when the permit was issued (1 August 2022). The contract’s requirement that the Commencement Date notification occur no later than 14 days after signing is subject to actual readiness conditions (permit availability).

Therefore, for purposes of delay and completion, the Commencement Date is 1 August 2022. This affects the calculation of the Time for Completion and any delay claims accordingly.
