Dubai Construction Disputes: Choosing Between DIAC and ICC Arbitration

Which arbitration institution applies to your construction dispute?

• DIAC is Dubai's only institutional arbitration centre and administers the majority of construction cases in the emirate. It applies the DIAC Arbitration Rules 2022.
• ICC is an international alternative frequently specified in FIDIC-based contracts and cross-border joint ventures. It applies the ICC Rules of Arbitration 2021 and is administered from Paris, with a regional office in Abu Dhabi.
• DIFC-LCIA no longer exists. It was abolished by Dubai Decree No. 34 of 2021. Contracts that still reference DIFC-LCIA arbitration create enforcement risk and should be amended.
• The answer depends on what your contract says, when it was signed, and where you need the award enforced.

Who this applies to

This article is for contractors, developers, subcontractors, consultants, and project companies involved in UAE construction projects who either need to commence arbitration or are reviewing dispute resolution clauses before signing.

It is less relevant to parties whose contracts are governed by ADGM or Abu Dhabi law, where arbitrateAD may be the more natural institutional choice. For a comparison of DIAC and arbitrateAD, see our separate guide on choosing the right UAE arbitration clause in 2026.

Why arbitration is the default for construction disputes in Dubai

Construction and real estate disputes account for approximately 59% of all DIAC arbitrations, making the sector the single largest source of cases. There are practical reasons for this.

Court litigation in the UAE is conducted in Arabic, which creates translation costs and procedural delay when the contract, correspondence, and technical evidence are in English. UAE court judgments are also difficult to enforce outside the GCC because enforcement depends on bilateral treaties, which are limited. Arbitration awards, by contrast, are enforceable in over 170 countries under the New York Convention.

For construction lawyers in Dubai, the ability to appoint arbitrators with construction and engineering expertise is equally important. In court, you get whoever is assigned. In arbitration, the parties can select a tribunal that understands FIDIC time bar provisions, delay analysis methodologies, or the technical basis of a variation claim.

DIAC for construction arbitration

DIAC is the default institution for most Dubai construction disputes. Following the 2021 consolidation under Decree No. 34, it is Dubai's only major arbitral centre, administering both onshore and DIFC-seated cases.

The DIAC Arbitration Rules 2022 modernised the institution's procedural framework and addressed several gaps that had frustrated practitioners under the earlier rules. Relevant features for construction cases include emergency arbitration for urgent interim relief (such as preventing a bond call or preserving evidence), joinder and consolidation provisions that allow related parties and contracts to be dealt with together, and an expedited procedure for claims under AED 1 million, with awards due within three months of tribunal constitution.

DIAC registered 355 cases in 2023 and reported sustained growth into 2024. In 2023, parties from 49 countries participated in DIAC arbitrations, and approximately half of all cases used the DIFC as the arbitral seat.

Seat selection matters. If the arbitration is seated in the DIFC, the DIFC Arbitration Law (DIFC Law No. 1 of 2008) governs the proceedings and the DIFC Courts act as the supervisory court. If the seat is onshore Dubai, UAE Federal Law No. 6 of 2018 applies and the Dubai Courts supervise. The choice of seat affects which court hears challenges to the award, applications for interim relief, and enforcement proceedings.

Costs. DIAC revised its fee schedule effective 1 January 2025, the first update since 2011. Registration costs USD 3,000 (non-refundable). Administrative fees and arbitrator fees scale with the amount in dispute. For a USD 5 million construction claim with a three-member tribunal, total institutional fees (registration, administration, and arbitrator fees) will typically fall in the range of USD 150,000 to USD 350,000 before legal costs.

Legal cost recovery. The DIAC Rules 2022 expressly empower tribunals to award the fees of legal representatives, which resolved a long-running ambiguity that had previously led to partial annulment of DIAC cost awards by the Dubai Court of Cassation.

Timeline. Standard construction arbitrations at DIAC typically resolve in 12 to 18 months. Expedited cases can close in three to five months. Complex multi-party disputes with extensive quantum evidence may run to 24 months.

ICC for construction arbitration

The International Chamber of Commerce (ICC) is the most commonly specified international institution in construction contracts, particularly where the contract is based on FIDIC forms or where one or more parties is a foreign contractor, investor, or lender.

ICC arbitration is administered from Paris and governed by the ICC Rules of Arbitration 2021. The ICC International Court of Arbitration oversees the proceedings and scrutinises awards before they are issued, a procedural step that DIAC does not currently perform. Award scrutiny does not revisit the merits, but it reviews the award for formal completeness and consistency, which can reduce the risk of challenge at the enforcement stage.

When ICC appears in construction contracts. FIDIC's standard recommended dispute resolution clause provides for ICC arbitration as a default. Many international EPC contracts, joint venture agreements, and project finance documentation also specify ICC rules. If a contract is silent on the institution but references the ICC Rules, the ICC administers.

Costs. The ICC uses an ad valorem fee structure based on published scales. Both administrative expenses and arbitrator fees are calculated according to the amount in dispute, with published minimum and maximum ranges. For a USD 5 million construction dispute, the ICC Cost Calculator indicates total institutional costs (administration and arbitrator fees for a three-member tribunal) in a broadly similar range to DIAC, though the ICC's advance-on-costs system requires parties to fund fees upfront before significant procedural steps are taken. The initial filing fee is USD 5,000 (non-refundable).

Legal cost recovery. Article 38(1) of the ICC Rules allows tribunals to award the reasonable legal and other costs incurred by the parties. Following a period of uncertainty, the Dubai Court of Cassation confirmed in November 2024 (Case No. 756 of 2024) that this provision does empower tribunals to award legal costs, including lawyers' fees. This reversed an earlier 2023 ruling that had found the ICC Rules insufficient to ground a legal costs award. The reversal is significant for construction arbitration, where legal costs in complex disputes are often substantial.

Timeline. ICC arbitrations are generally comparable to DIAC in duration. Standard construction cases resolve in 12 to 18 months. The ICC's Terms of Reference phase and award scrutiny process add modest procedural steps, though neither typically causes significant delay in practice. The ICC's expedited procedure (available for disputes under USD 5 million, or by agreement) appoints a sole arbitrator and targets a six-month timeline.

Enforcement. ICC awards seated in Dubai or the DIFC are enforceable under the New York Convention in the same way as DIAC awards. The ICC's global recognition and the scrutiny process can provide additional comfort to parties who anticipate enforcement in jurisdictions where DIAC is less well known.

What happened to the DIFC-LCIA

The DIFC-LCIA Arbitration Centre was abolished by Dubai Decree No. 34 of 2021, effective 14 September 2021. The Decree also abolished the Emirates Maritime Arbitration Centre (EMAC). Both institutions' cases, assets, and obligations were transferred to DIAC.

This matters for construction because the DIFC-LCIA was widely specified in UAE construction contracts, particularly in DIFC-seated arbitrations and in contracts between international parties. Many of these contracts remain in force.

The legal position. Article 6 of Decree No. 34 provides that arbitration agreements referencing the DIFC-LCIA remain valid and effective, and that DIAC replaces the DIFC-LCIA in administering disputes under those agreements, unless the parties agree otherwise. Article 8(c) substitutes the DIAC Arbitration Rules 2022 for the DIFC-LCIA Rules.

UAE courts support this position. The DIFC Court of First Instance (in Narciso v Nash, ARB 009/2024, a construction subcontract dispute) confirmed that Decree No. 34 forms part of DIFC law and that DIFC-LCIA arbitration agreements are valid and enforceable, with DIAC stepping in as the administering institution. The Abu Dhabi Court of Appeal reached the same conclusion in Case No. 449/2024. Both courts treated the Decree as preserving, not invalidating, the parties' agreement to arbitrate.

Foreign courts have been less predictable. A Louisiana district court initially found the DIFC-LCIA clause unenforceable because the institution no longer existed, though the Fifth Circuit reversed that decision in January 2025. The Singapore High Court enforced a DIAC provisional award made under a DIFC-LCIA clause, but only because the respondent had participated without objecting to jurisdiction.

Practical risk. A counterparty who wants to delay proceedings has a ready-made jurisdictional argument if your contract still references DIFC-LCIA. Even where UAE courts will ultimately uphold the clause, the argument takes months to resolve and costs money. Enforcement in foreign courts adds further unpredictability.

What to do. If your construction contract references DIFC-LCIA or EMAC arbitration, amend the dispute resolution clause to specify DIAC (or another active institution) before a dispute arises. If you cannot agree on an amendment, at least document that both parties acknowledge DIAC as the successor institution.

Practical comparison

When to use DIAC

DIAC is the right choice for most Dubai construction disputes. It is the only institutional option for parties who want a Dubai-administered arbitration, and its caseload is dominated by construction and real estate matters. The Arbitration Court and case management team are experienced in construction disputes, and the rules are designed to handle the joinder and consolidation scenarios that arise when multiple contracts on the same project produce related claims.

Choose DIAC when the contract is between UAE-based parties, the project is in Dubai, and enforcement is expected in the UAE or other New York Convention jurisdictions. DIAC is also the practical option for FIDIC claims where the contract does not specify another institution, or where parties amending a defunct DIFC-LCIA clause want a local replacement.

When to use ICC

ICC arbitration makes sense for construction disputes with a significant international element: cross-border joint ventures, EPC contracts with foreign contractors, or projects backed by international lenders whose facility agreements specify ICC rules. It is also the natural choice where enforcement is anticipated in jurisdictions where DIAC is less established, or where the parties value the ICC Court's award scrutiny process as a safeguard against formal defects.

The main practical differences are cost structure and procedural overlay. ICC's advance-on-costs system requires upfront funding, which can be a cash flow issue in construction disputes where the claimant is already unpaid. ICC also conducts a Terms of Reference phase early in the proceedings, which adds a procedural step but helps crystallise the issues and scope of the arbitration.

For parties with existing FIDIC contracts that specify ICC, there is usually no reason to change. The institution is well suited to multi-jurisdictional construction disputes, and the November 2024 Dubai Court of Cassation ruling on legal costs has removed the most significant practical concern about ICC arbitration seated in the UAE.

When legacy DIFC-LCIA clauses cause problems

The risk is not theoretical. In the DIFC Court case Narciso v Nash, the underlying dispute was a construction subcontract where the DIFC-LCIA clause led to parallel proceedings in Sharjah and a jurisdictional fight before the DIFC Court. The substance of the dispute, a claim for breach and wrongful termination, was delayed while the parties argued about which institution and which rules applied.

If your construction contract references DIFC-LCIA, you have three practical options. Amend the clause by agreement to specify DIAC (the cleanest solution). Commence arbitration at DIAC under Decree No. 34 and rely on the Decree's transitional provisions (workable in the UAE, but carries enforcement risk abroad). Or agree to LCIA arbitration under the DIFC-LCIA Rules, which the LCIA has confirmed it will administer from London for cases commenced after the transition date.

The worst option is doing nothing and waiting for a dispute to force the issue. That gives the other side a procedural weapon.

Enforcement of construction arbitration awards in the UAE

Construction awards are enforced through the same process as any other arbitration award. For awards seated in the DIFC, the winning party applies to the DIFC Courts, which can then be executed onshore through the established reciprocal enforcement framework. For awards seated onshore in Dubai, the application goes to the Dubai Court of Appeal.

Under UAE Federal Law No. 6 of 2018, the court has a 60-day window to rule on recognition and enforcement applications. Grounds for refusal mirror the New York Convention and are limited: invalidity of the arbitration agreement, procedural irregularity, excess of jurisdiction, incorrect tribunal composition, or conflict with UAE public policy.

A practical point for construction disputes: liquidated damages clauses and bank guarantee calls often run in parallel with arbitration proceedings. The availability of emergency arbitrators under both DIAC and ICC rules can be critical for obtaining interim relief before the full tribunal is constituted, particularly where a bond call is imminent or assets are at risk of dissipation.

What construction companies should do now

Audit existing contracts. Identify any construction contracts, subcontracts, consultancy agreements, or joint ventures that still reference DIFC-LCIA or EMAC. These should be amended to specify an active institution.

Specify the seat precisely. Avoid "the UAE" as the seat of arbitration. Name the specific seat: "DIFC, Dubai" or "Dubai, UAE" (onshore) or "ADGM, Abu Dhabi." This determines the supervisory court and the applicable arbitration law.

Choose the right institution for the contract. For domestic construction disputes, DIAC is the default. For international EPC contracts or FIDIC-based projects with foreign parties, ICC is a well-established alternative. For Abu Dhabi projects, consider arbitrateAD.

Budget for costs early. Arbitration is not cheap, but it is faster and more enforceable than litigation through the Dubai Courts. For unpaid interim payment certificates and contract termination disputes, a well-drafted arbitration clause is the difference between recovering in months and recovering in years.

Watch for clause defects. An even number of arbitrators, a missing seat, a unilateral election right, or a reference to a defunct institution can each derail the proceedings before the merits are reached.

Legal advice may be required to assess which institution and seat are appropriate for your project structure and counterparty risk profile.

Update note: This article reflects the position as of March 2026. The enforceability of legacy DIFC-LCIA clauses remains subject to ongoing judicial interpretation in the UAE and abroad. Parties with existing DIFC-LCIA clauses should treat amendment as a priority. The DIAC fee schedule referenced is the 2025 version effective from 1 January 2025.
