Under FIDIC Red Book 1999, Sub-Clause 1.3 [Communications] governs the delivery of notices and other communications. The clause clearly specifies that communications must be sent to the addresses stated in the Contract Data. This ensure s certainty, traceability, and contractual validity of all formal correspondence between the Parties.
Option A is therefore correct, as the Contract Data defines the official addresses for communication. These addresses are agreed at the outset and form the primary reference point for valid notice delivery.
Option B is also correct. Sub-Clause 1.3 further allows that if a Party notifies the other of a change of address, then communications may be delivered to that updated address. This reflects practical contract administration, where offices or contact details may change during the project lifecycle. However, such change must be formally communicated.
Option C is incorrect because the Site address is not automatically a valid address for formal notices unless explicitly stated in the Contract Data. Delivering notices to the Site could create disputes regarding receipt and validity.
Option D is also incorrect. While the Contractor’s Representative plays a key role in project execution (under Clause 4.3), the Representative’s address is not necessarily the formal address for contractual notices unless it is specifically designated in the Contract Data.
This clause highlights the importance of proper notice procedures in FIDIC contracts, as improper delivery may invalidate claims or contractual rights.
