DAAB stands for Dispute Avoidance/Adjudication Board: the one or three independent experts who, under Clause 21 of the FIDIC 2017 contracts, help the parties avoid disputes and decide those they cannot. Its decision binds both parties as soon as it is given. If neither side gives a notice of dissatisfaction within 28 days of receiving it, the decision becomes final and binding and can no longer be revised in arbitration.
DAAB Meaning and Full Form in FIDIC
The full form is Dispute Avoidance/Adjudication Board, and the slash is deliberate. One board does two jobs that most dispute systems keep apart. It helps the parties resolve disagreements informally while the project runs, and it adjudicates formal Disputes when that fails. It is the board of the 2017 Red, Yellow and Silver Books.
In construction, the DAAB sits between the Engineer and the arbitrators. A claim goes first to agreement or determination by the Engineer under Sub-Clause 3.7 (by the Employer's Representative under Sub-Clause 3.5 in the Silver Book), then to the board, then to arbitration. FIDIC's Golden Principles treat referral to the board as a condition precedent to arbitration, unless the governing law conflicts.
The board is not an arbitral tribunal, and Clause 21 says so expressly: the DAAB proceeding is not an arbitration. That is why the FIDIC dispute resolution clause treats the two as separate rungs. The board gives a fast answer that must be obeyed and becomes final if nobody challenges it in time. Arbitration gives the final answer when someone does.
DAB vs DAAB: What Changed From the 1999 Dispute Adjudication Board
DAB is the older term: the Dispute Adjudication Board of Sub-Clauses 20.2 to 20.8 in the 1999 forms, still common on Gulf projects. The DAAB keeps the 84-day decision and the 28-day window to object, and changes four things.
The first is timing. The 1999 Red Book had a standing board, but the Yellow and Silver Books appointed one ad hoc after a dispute arose. The 2017 suite makes the board standing in all three books. The second is avoidance, now a formal function under Sub-Clause 21.3.
The third is enforcement. The 1999 non-compliance wording reached only final and binding decisions, a gap that fed years of Singapore litigation known as the Persero cases. Sub-Clause 21.7 now covers any decision. The fourth is pace, shown below and in FIDIC 2017 vs 1999.
| Feature | 1999 DAB | 2017 DAAB |
|---|---|---|
| Full form | Dispute Adjudication Board | Dispute Avoidance/Adjudication Board |
| When appointed | Standing in the Red Book, ad hoc in the Yellow and Silver Books | Standing in all three books, from the start |
| Avoidance role | Opinion on a joint request, if a standing board existed | Informal assistance under Sub-Clause 21.3 |
| Referral deadline | No time bar | 42 days after the NOD on the Engineer's determination |
| Notice of dissatisfaction | 28 days | 28 days, may cover part of a decision |
| Amicable settlement | 56 days | 28 days |
| Failure to comply | Direct to arbitration only if final and binding | Direct to arbitration, binding or final |
| No board in place | Arbitration under 20.8, not a free opt-out from an ad hoc board | Arbitration under 21.8 unless a board is being constituted, with a costs risk |
For a contractor, the change is commercial before it is legal. Not a board convened after the relationship has broken down. A board that already knows the site and the people when the first disagreement arrives.
How Does the DAAB Avoid Disputes?
Sub-Clause 21.3 lets the parties jointly ask the DAAB for assistance, or to discuss informally and try to resolve any issue that has arisen. The board may invite such a request. Either way, no request may be made while the Engineer is dealing with the same matter under Sub-Clause 3.7, unless the parties agree.
Neither party is bound by advice given this way, and the board is not bound by it in any later decision. Its value is an early, cheap view from the people who would decide any referral. A disagreement over a rate can end at a site meeting.
That is what a DAB or DAAB meeting means in practice. The DAAB Procedural Rules provide for an introductory meeting, then meetings and site visits every 70 to 140 days unless agreed otherwise. They are held in person save in exceptional circumstances. A standing board only prevents disputes if it is actually on site.
How a DAAB Referral and Decision Work Under Clause 21
The formal route runs in a fixed order, each step with its own clock. First, a party dissatisfied with the Engineer's determination gives a notice of dissatisfaction, or NOD, within 28 days under Sub-Clause 3.7.5. If the Engineer determines nothing within the time limit, a Claim is deemed rejected and the 28 days run from the end of that limit. With no NOD, the determination becomes final and binding. Second, the Dispute must be referred to the DAAB within 42 days of that NOD, or the NOD lapses and is no longer valid under Sub-Clause 21.4.1, leaving the contractor exposed to the argument that the determination has become final.
Third, the board gives a reasoned decision within 84 days of receiving the referral, or another period it proposes and the parties agree. If the board misses its deadline, either party may give a NOD within 28 days after it expires. Fourth, a dissatisfied party may give a NOD within 28 days of receiving the decision, covering all or part of it. Fifth, the parties attempt amicable settlement under Sub-Clause 21.5, but ICC arbitration may begin on or after the 28th day after the NOD unless they agree otherwise.
Take a disputed QAR 4 million variation. If the Engineer determines nothing is due, the contractor has 28 days to object, 42 more to refer, and the board 84 days to decide. A decision that the sum is owed makes it immediately due, without certification or Notice. None of that helps if the FIDIC fully detailed claim beneath it was weak.
A referral is deemed to interrupt any limitation or prescription period, unless the law prohibits that. Whether a contract can interrupt prescription is a question for the governing law, so diarise the statutory limitation dates independently rather than rely on the referral. Where your contract incorporates FIDIC's 2022 amendments, some matters, such as certain payment failures and disputed termination notices, skip the Engineer's determination.
Is a DAAB Decision Binding?
Yes. A DAAB decision binds both parties from the moment it is given, and they must comply promptly whether or not anyone gives a NOD, and the Employer answers for the Engineer's compliance. A NOD does not suspend the obligation to pay. It stops the decision becoming final.
FIDIC's published guidance on the 1999 forms says that after a NOD it is the dispute, not the decision, that the tribunal reopens. Sub-Clause 21.6 gives the arbitrators full power to open up, review and revise any DAAB decision that is not yet final, and neither party is limited to the evidence or arguments it put to the board. A decision can be binding and not final. With no NOD inside 28 days, it becomes both.
Sub-Clause 21.7 deals with the party that refuses. The other side can refer the failure itself straight to arbitration, skipping a fresh referral and amicable settlement. The tribunal may enforce the decision summarily, by an interim or provisional measure or an award, with the merits reserved where the decision is not yet final, though enforcing that award still depends on the courts at the seat.
The 2017 books add pressure. Where the Employer's non-compliance is a material breach, the Contractor may suspend on at least 21 days' Notice under Sub-Clause 16.1 and ultimately terminate under Sub-Clause 16.2.1. The Employer has a matching ground under Sub-Clause 15.2.1. Ignoring a decision is not a negotiating position. It is a breach.
The DAAB Agreement, Appointment and Who Pays
Each member's authority comes from the DAAB Agreement between the Employer, the Contractor and that member. It incorporates the General Conditions of DAAB Agreement and the DAAB Procedural Rules printed with the FIDIC conditions, which govern independence, fees, meetings and hearings. The board is constituted only when the parties and every member have signed, or are deemed to have signed after an appointment under Sub-Clause 21.2.
Under Sub-Clause 21.1 the parties jointly appoint one member or three, three being the default. The deadline is the time in the Contract Data, defaulting in the Red Book to 28 days after the Letter of Acceptance. If they cannot agree, Sub-Clause 21.2 lets either party apply to the appointing official, by default the President of FIDIC or a nominee, who under the 2022 reprint also sets the fees. The official's appointment, including the fees, is final and conclusive, and FIDIC treats an appointment request as a last resort.
Each party bears half the members' fees, whatever the outcome. The monthly fee buys availability and a member who keeps up with the project. The daily fee covers visits, hearings and decisions. The Contractor pays each invoice within 28 days and reclaims half through its Statements. A board with an overdue invoice need not release its decision until it is paid, so a fee dispute can stall your referral.
What Happens If No DAAB Is in Place?
Boards are not always appointed on time. Sub-Clause 21.8 applies where a Dispute arises and no DAAB is in place or being constituted, whether because its appointment expired or otherwise. The referral and amicable settlement steps then fall away, and the Dispute may go directly to arbitration.
That exit has limits. Sub-Clause 21.8 does not apply while a DAAB is being constituted, so a party that starts the Sub-Clause 21.2 appointment process closes it, and Sub-Clause 21.6 lets the arbitrators weigh in costs a party's failure to cooperate in constituting the board. Courts also police the 1999 equivalent. In Peterborough City Council v Enterprise Managed Services (2014), the English Technology and Construction Court held that, for the ad hoc board of an amended 1999 Silver Book, 'no DAB in place' was not a unilateral opt-out, and stayed the Council's court action so the board could decide first. The judge thought the clause was aimed at standing boards that had ceased to be in place, so the case is a warning rather than a rule for 2017 contracts.
The practical answer is to force the appointment under Sub-Clause 21.2 rather than argue about its absence. On any project, read the Particular Conditions first, because amendments to Clause 21 change the route. Then decide who prepares the referral. The claims consultant vs lawyer comparison sets out who does what at each dispute stage.
In CALIM's experience across dozens of engagements, the board that costs a contractor money is rarely the one that decided against it. It is the board nobody appointed, or the NOD that went out on day 29.
At CALIM, we diarise every Clause 21 window from the Engineer's determination onward, press for the board's appointment at mobilisation, and build referrals on the contemporaneous record. That work sits at the centre of our construction dispute resolution support, and it starts long before anything is referred.
Frequently Asked Questions
What does DAAB stand for?
DAAB stands for Dispute Avoidance/Adjudication Board. It is the dispute board in the 2017 FIDIC Red, Yellow and Silver Books, governed by Clause 21. Its one or three independent members are appointed jointly at the start of the contract. It helps the parties avoid disputes through informal assistance and decides formal Disputes, normally within 84 days. In the 2017 editions it replaced the 1999 Dispute Adjudication Board, or DAB.
Is a DAAB decision binding?
Yes. A DAAB decision binds both parties immediately, and they must comply promptly even if one of them gives a notice of dissatisfaction. That notice only stops the decision becoming final, and it must be given within 28 days of receiving the decision. If neither party gives one, the decision becomes final and binding. If a party refuses to comply, the other can refer the failure directly to arbitration under Sub-Clause 21.7.
What is the difference between a DAB and a DAAB?
A DAB is the Dispute Adjudication Board of the 1999 FIDIC forms, and a DAAB is the Dispute Avoidance/Adjudication Board of the 2017 forms. The 1999 DAB was a standing board under the Red Book but an ad hoc board under the Yellow and Silver Books, appointed after a dispute arose. The DAAB is standing in all three books and has a formal avoidance role. The 2017 wording also adds a 42-day referral limit, cuts the amicable settlement period from 56 to 28 days, and lets a failure to comply with any decision, not only a final one, go straight to arbitration.
Who pays for the DAAB?
The Employer and the Contractor each pay half of the DAAB's fees, whatever the outcome of the disputes it decides. Each member earns a monthly fee for staying available and informed, and a daily fee for meetings, site visits, hearings and decisions. Under the General Conditions of DAAB Agreement, the Contractor pays each invoice within 28 days and reclaims half from the Employer through its Statements. If the Contractor fails to pay, the Employer pays and recovers the excess.
What happens if the DAAB is never appointed?
Either party can apply under Sub-Clause 21.2 to the appointing official, by default the President of FIDIC or a nominee, who appoints the members and fixes their fees. Sub-Clause 21.8 lets a Dispute go straight to arbitration where no DAAB is in place or being constituted, but relying on that is risky. The route closes once either party starts constituting a board, an English court refused in 2014 to treat the 1999 equivalent as a free opt-out from an ad hoc board, and the 2017 wording lets a tribunal penalise non-cooperation when it awards costs.
The board that matters most is the one appointed before anyone needs it.
