Under FIDIC 2017, Clause 20 introduces a structured and unified claims procedure applicable to both Contractor’s and Employer’s Claims. Claims are categorized broadly into:

Claims for time and/or money (Sub-Clause 20.2), and

Other claims (e.g., disputes or matters under Sub-Clause 20.1(c)).

Option A is correct. The 28-day time bar under Sub-Clause 20.2.1 applies to all claims for time and/or money and is a fundamental procedural requirement. Importantly, unlike FIDIC 1999, this time bar applies equally to both Parties, reinforcing fairness and discipline in claims management.

Option C is also correct. Claims under Sub-Clause 20.1(a) and (b) (typically relating to payment and/or extension of time) are processed under Sub-Clause 20.2, and the Engineer (or Employer’s Representative in the Silver Book) must agree or determine the claim in accordance with Sub-Clause 3.7 (Red/Yellow) or 3.5 (Silver).

Option B is incorrect because claims under 20.1(c) are not handled through Sub-Clause 3.7/3.5 in the same structured determination process as time/money claims.

Option D is incorrect because FIDIC 2017 clearly applies the time bar to both Employer and Contractor claims, which is a key update from earlier editions.

This reflects FIDIC 2017’s emphasis on symmetry, procedural clarity, and proactive claim management.
