1️⃣ Purpose of the Clause
Let’s start by understanding why these clauses even exist.
🧾 Clause 20.5 (1999) – The “Cool-Down” Clause
This clause was designed as a mandatory cooling-off period. Once a party says, “I don’t accept the DAB’s decision” (by issuing a Notice of Dissatisfaction), FIDIC tells both parties, “Alright, pause. Take 56 days to try and talk it out before jumping into arbitration.”
It’s a good-faith nudge toward negotiation. But here’s the catch—it’s not enforced. Even if the parties just sit there and do nothing for 56 days, they’re free to proceed to arbitration. So while it sounds cooperative, it’s more of a procedural speed bump than a genuine attempt at resolution.
🤝 Clause 21.3 (2017) – The “Let’s Fix This Early” Clause
Now this is where things get interesting. FIDIC took a huge leap forward in 2017 with a major mindset shift. Instead of waiting until a full-blown dispute erupts, Clause 21.3 brings in the DAAB (Dispute Avoidance/Adjudication Board) before things go off the rails.
Think of it like relationship counseling. The DAAB isn’t just there for the messy breakup (arbitration)—they’re there to help keep the relationship on track from the start.
👉 In short:
- 1999: “Talk it out, if you feel like it.”
- 2017: “Let’s not even get to the fighting stage.”
2️⃣ Clause Breakdown – What’s Actually Written?
📜 1999 Clause 20.5 – Full Text
“Where notice of dissatisfaction has been given under Sub-Clause 20.4 above, both Parties shall attempt to settle the dispute amicably before the commencement of arbitration. However, unless both Parties agree otherwise, arbitration may be commenced on or after the fifty-sixth day after the day on which notice of dissatisfaction was given, even if no attempt at amicable settlement has been made.”
✅ Key points:
- Only kicks in after a DAB decision is rejected.
- There’s a 56-day waiting period before arbitration can start.
- No actual requirement to engage in settlement talks.
So really, you just wait 56 days, and you’re free to go to arbitration—even if no one talked or tried to solve the issue.
📘 2017 Clause 21.3 – Key Provisions
“If the Parties so agree, they may jointly request… the DAAB to provide assistance and/or informally discuss and attempt to resolve any issue… If the DAAB becomes aware of an issue… it may invite the Parties to make such a joint request… If the Parties make such a request, the DAAB shall provide such assistance as it considers appropriate.”
✅ Key features:
- The DAAB can be involved at any time, not just after disputes arise.
- It’s voluntary—both parties must request it together.
- The DAAB can offer advice, facilitate dialogue, and help clarify misunderstandings.
- Importantly, the DAAB’s informal advice is non-binding.
This clause shifts the focus from “how do we fix this after it’s broken?” to “how do we stop it from breaking at all?”
3️⃣ What Does This Mean in Practice?
Let’s break down the real-world implications of these two approaches:
🚨 1999 Risks
- No incentive to genuinely attempt resolution.
- The DAB has no further role after giving its decision.
- Disputes often escalate straight to arbitration.
- It’s reactive—you deal with problems only after they explode.
✅ 2017 Benefits
- Encourages open dialogue before issues become formal disputes.
- Keeps the DAAB actively involved throughout the project, not just during conflicts.
- Reduces the need for expensive, time-consuming arbitration.
- Builds trust between parties by promoting early resolution of misunderstandings.
💡 It’s like maintaining a car—regular checkups (DAAB involvement) help you avoid a total breakdown (arbitration).
4️⃣ How Do These Clauses Connect to the Rest of the Contract?
These clauses don’t stand alone—they’re part of a bigger dispute resolution ecosystem in FIDIC.
🔗 1999 Clause 20.5 is linked to:
- Clause 20.4: The DAB’s decision comes first.
- Once a party gives a Notice of Dissatisfaction, the 56-day clock under Clause 20.5 starts.
🔗 2017 Clause 21.3 interacts with:
- Clause 21.1: Sets up the DAAB.
- Clause 21.4: Formal DAAB decisions follow if informal avoidance fails.
- Clause 3.7: DAAB must pause informal help while the Engineer is making a formal determination (unless both parties agree otherwise).
📌 The DAAB’s ability to offer informal help in 21.3 is unique to 2017—it’s not an option in 1999.
5️⃣ What If…? 🤔
Let’s spice this up with some hypothetical scenarios:
❓ What if the parties disagree on using the DAAB informally in 2017?
- No joint request = no DAAB involvement. It has to be mutually agreed.
❓ Can a DAAB later change its mind after giving informal advice?
- Absolutely. Informal opinions under 21.3 are non-binding and don’t tie the DAAB’s hands later.
❓ What if the parties do nothing during the 56 days under 1999 Clause 20.5?
- That’s allowed. The contract still permits arbitration after that period, even if no amicable settlement was attempted.
So in 1999, the window is more symbolic. In 2017, it’s a live tool for managing relationships.
6️⃣ Room for Improvement – Can These Clauses Be Better?
✏️ Suggestions for 1999:
- Add language to require actual negotiation efforts during the 56-day window.
- Incorporate a standing DAB to allow early-stage dispute handling like in the 2017 edition.
✏️ Suggestions for 2017:
- In Particular Conditions, define:
- Time limits for how long DAAB has to respond to a joint request.
- Whether DAAB informal notes are documented or off-the-record.
- Consider adding a mechanism where the DAAB can strongly recommend a joint session even without a request.
7️⃣ Final Takeaways – What Should You Remember?
🧩 Feature | 1999 – Clause 20.5 | 2017 – Clause 21.3 |
---|---|---|
When It Applies | After a DAB decision | Anytime during the contract |
Parties’ Role | Passive (wait 56 days) | Active (joint request) |
DAAB Involvement | None | Central and ongoing |
Nature of Assistance | None | Informal and advisory |
Binding Effect | No | No (informal only) |
Goal | Delay arbitration | Prevent disputes from escalating |
🎓 Contractual Wisdom:
1999’s approach is like installing a fire alarm—good to have when things go wrong.
2017’s approach is like installing a sprinkler system—you manage the heat before the fire starts.

Additional Frequently Asked Questions (FAQs)
What is an arbitration agreement?
An arbitration agreement is a legal contract between two or more parties agreeing to resolve any disputes through arbitration rather than through litigation in court. This agreement can be a standalone contract or a clause within a larger contract. It specifies the rules, venue, and manner in which the arbitration will be conducted, and it is generally binding on all parties involved.
What is the difference between mediation and arbitration?
Both mediation and arbitration are forms of alternative dispute resolution, but they serve different purposes and have different implications:
-
Mediation: In mediation, a neutral third party, known as a mediator, facilitates a discussion between the disputing parties to help them reach a mutually agreeable solution. The mediator does not make a decision for the parties but rather assists them in negotiation. Mediation is generally non-binding unless the parties agree to a settlement.
-
Arbitration: In arbitration, a neutral third party, known as an arbitrator, hears the evidence and arguments presented by the disputing parties and makes a decision. Unlike mediation, arbitration is usually binding, and the arbitrator’s decision is enforceable by law.
What is binding arbitration?
Binding arbitration is a form of arbitration where the decision made by the arbitrator is final and legally binding on all parties involved. This means that the parties waive their right to a court trial and agree to abide by the arbitrator’s decision. The decision can be enforced in a court of law if necessary.
What is the difference between arbitration and mediation?
While both are alternative dispute resolution methods, the key difference lies in the role of the third-party facilitator and the binding nature of the decision:
-
Arbitration: The arbitrator makes a binding decision based on the evidence and arguments presented.
-
Mediation: The mediator facilitates discussion and negotiation but does not make a binding decision.
What is an arbitration clause?
An arbitration clause is a section within a contract that specifies that any disputes arising out of the contract will be resolved through arbitration rather than litigation. This clause outlines the rules, venue, and procedures that will be followed in the event of a dispute.
What is arbitration in law?
In law, arbitration is a legal technique for resolving disputes outside the court system. Parties involved in a dispute present their case to a neutral third party, known as an arbitrator, who then makes a decision that is usually binding. Arbitration is often faster, less formal, and less expensive than litigation.
