FIDIC contracts in Poland – dispute resolution

A Warsaw-based infrastructure developer signs a FIDIC Yellow Book contract with a Polish general contractor. Construction runs 14 months over schedule. The employer withholds payment. The contractor threatens arbitration. Both sides have missed at least one contractual notice deadline – and neither party is certain which dispute resolution step comes next. This scenario plays out regularly on Polish construction sites, and the procedural missteps that follow cost clients far more than the underlying claim.

FIDIC contracts used in Poland follow a four-stage dispute resolution ladder: Engineer decision, Dispute Avoidance/Adjudication Board (DAAB) referral, amicable settlement period, and finally arbitration or litigation. Polish law governs the underlying construction contract through the Kodeks cywilny (Civil Code, KC) and the Prawo budowlane (Construction Law Act, PBA), while the Kodeks postępowania cywilnego (Code of Civil Procedure, KPC) frames any court proceedings. Missing a 28-day notice of dissatisfaction after a DAAB decision can permanently forfeit the right to proceed to arbitration.

This guide walks through each stage of the FIDIC dispute resolution process as it applies in Poland. It covers the Engineer's role, DAAB appointment mechanics, the amicable settlement window, arbitration versus litigation choices, and the most costly procedural mistakes. Three business scenarios – a public infrastructure project, a private commercial development, and a cross-border joint venture – illustrate how the rules operate in practice.

How does the FIDIC dispute ladder work in Poland?

The FIDIC dispute resolution ladder is sequential. Each rung must be completed before the next becomes available. Under the 2017 FIDIC suite, the Engineer acts first – issuing a determination within 42 days of a claim submission. That determination is binding unless challenged. Polish public procurement projects, supervised by the Urząd Zamówień Publicznych (Public Procurement Office, UZP), frequently incorporate FIDIC Red Book or Yellow Book conditions with minimal modification, making the Engineer's role particularly significant on state-funded works.

If a party disputes the Engineer's determination, it must refer the matter to the DAAB within the contractually specified period – typically 28 days. The DAAB then has 84 days to issue its decision. That decision is immediately binding. Both parties must comply promptly, even if they intend to challenge it. Failure to comply with a binding DAAB decision is itself a separate breach, and Polish courts – including the Sąd Arbitrażowy przy Krajowej Izbie Gospodarczej (Court of Arbitration at the Polish Chamber of Commerce, SA KIG) – have treated non-compliance as an aggravating factor in subsequent proceedings.

After the DAAB decision, either party may issue a notice of dissatisfaction within 28 days. This deadline is strict. Missing it converts the decision into a final award, closing the path to arbitration entirely. The amicable settlement period then runs for 56 days. Only after that window closes – without resolution – does the right to arbitrate crystallise. Many Polish practitioners treat the amicable period as a formality, but it can serve as a useful negotiation reset, particularly on long-term infrastructure projects where the parties must continue working together.

Engineer determination – 42-day response window
DAAB referral – 84-day decision period
Notice of dissatisfaction – 28-day deadline (strict)
Amicable settlement – 56-day window
Arbitration or litigation – available after amicable period expires

What are the DAAB appointment rules and common pitfalls?

The DAAB is the centrepiece of FIDIC's 2017 dispute avoidance architecture. Under the 2017 Red and Yellow Books, a standing three-member DAAB must be appointed at the start of the project – not after a dispute arises. This is a fundamental shift from the 1999 Dispute Adjudication Board (DAB) model, which parties sometimes appointed only when needed. Polish construction contracts frequently copy 1999 FIDIC language into 2017 frameworks, creating dangerous inconsistencies.

Appointment must happen within 28 days of the contract's commencement date. If the parties cannot agree on DAAB members, the appointing authority named in the contract – often the SA KIG or an international body such as the ICC International Court of Arbitration – makes the appointment. DAAB members must be independent and impartial. Polish law reinforces this through the KC's general principles on conflicts of interest, and the Polska Izba Inżynierów Budownictwa (Polish Chamber of Civil Engineers, PIIB) maintains a register of qualified adjudicators.

We secured interim measures protecting assets worth over EUR 3m for a German investor's subsidiary in Lower Silesia (spring 2025). The case arose because the DAAB had never been formally constituted – the employer had delayed appointment, and the contractor had not pressed the point. When the dispute emerged, both parties lost 11 months navigating jurisdictional uncertainty before the arbitral tribunal could address the merits.

Common pitfalls at the DAAB stage include: failing to pay the DAAB members' retainer fees on time (which can suspend the Board's obligations), submitting claims without the required supporting documentation, and treating site visits as optional. The DAAB's site visit schedule – typically every 70 to 140 days on major projects – is contractually mandated and helps the Board understand the factual record before any formal referral.

How should parties choose between arbitration and Polish court litigation?

Once the amicable settlement period expires without resolution, the claimant must choose a forum. FIDIC's standard arbitration clause designates ICC arbitration under the ICC Rules, with the seat of arbitration to be agreed. In Poland, parties frequently designate Warsaw as the seat, bringing the SA KIG or the Vienna International Arbitral Centre into play as alternatives to the ICC. Each choice carries different cost and timeline implications.

ICC arbitration for a mid-sized construction claim – say, PLN 15m to PLN 50m – typically costs EUR 80,000 to EUR 200,000 in ICC administrative fees and arbitrator fees alone, before legal costs. Proceedings run 24 to 36 months on average. Polish court litigation before the Sąd Okręgowy (Regional Court) is cheaper in court fees – capped at PLN 200,000 for the highest-value claims – but first-instance proceedings in construction disputes regularly take 36 to 48 months, with appeals adding another 18 to 24 months.

For foreign investors, arbitration offers a significant practical advantage: awards rendered in ICC or SA KIG proceedings are enforceable across more than 160 jurisdictions under the New York Convention. A Polish court judgment requires separate enforcement proceedings in each target jurisdiction. If your counterparty has assets in multiple countries, this distinction is commercially decisive. Investors exploring cross-border structures can find additional context on jurisdictional considerations at our Luxembourg real estate practice page.

Three scenarios illustrate the choice. A Polish public authority as employer on a motorway project will often insist on SA KIG arbitration seated in Warsaw – politically simpler and domestically enforceable. A private developer with a German joint-venture partner will typically prefer ICC arbitration with a neutral seat. A smaller commercial lease dispute (below PLN 500,000) may be better served by Polish Regional Court proceedings, where the cost-to-claim ratio favours litigation.

What notice and claims obligations must contractors and employers meet?

Notice requirements under FIDIC are not administrative formalities. They are conditions precedent to entitlement. Under the 2017 Yellow Book, a contractor claiming additional time or money must give notice within 28 days of becoming aware – or of when it should have become aware – of the event giving rise to the claim. Missing this deadline does not automatically extinguish the claim under Polish law, but it significantly weakens the contractor's position and may reduce the recoverable amount.

Polish courts have applied KC principles of good faith to soften strict FIDIC notice bars in some cases. However, relying on judicial discretion is a poor strategy. The safer approach is a contemporaneous claims register – updated weekly – that documents every potential entitlement event as it occurs. This register becomes the evidential backbone of any DAAB referral or arbitration. We helped a manufacturing-sector client in Małopolska (autumn 2024) recover over PLN 4m in delay damages after reconstructing a claims register from site diaries and correspondence – a process that took four months and cost more than the register would have cost to maintain in real time.

Employers face symmetric obligations. A payment certificate withheld without a valid withholding notice under the contract exposes the employer to financing charges and, in some FIDIC editions, suspension rights for the contractor. Under Polish construction law, the employer's obligations to subcontractors – including direct payment liability – run in parallel with the FIDIC payment mechanism. This dual-track exposure is a recurring issue on Polish public infrastructure projects, where subcontractor claims against the employer are governed by PBA provisions that cannot be contractually excluded.

For background on how regulatory screening affects foreign-owned project companies, the UOKiK foreign investment screening guide provides a useful overview of approval timelines that can affect project commencement and, consequently, FIDIC claim windows.

What are the most costly mistakes in Polish FIDIC disputes?

The most expensive mistake is treating the FIDIC process as a formality before "real" litigation. Parties that do not take the DAAB seriously – failing to prepare thorough referral submissions, skipping site visits, or ignoring the DAAB's procedural directions – arrive at arbitration with a thin factual record and a hostile procedural history. Arbitral tribunals read DAAB files. A poorly presented DAAB referral can undermine credibility at the arbitration stage.

The second major mistake is currency mismatch in claim quantification. Polish construction contracts often price in PLN but reference EUR-denominated equipment or materials. When the PLN/EUR rate moves significantly during a delayed project, the quantification of additional costs becomes genuinely complex. Claims that ignore exchange-rate exposure – or that apply the wrong contractual rate date – are routinely reduced by arbitral tribunals. A real estate tax reclassification dispute can have similar valuation complexity; the 2025 reclassification disputes guide addresses comparable valuation methodology issues.

Third: failing to preserve evidence during construction. FIDIC disputes are fact-intensive. Photographs, daily logs, RFI registers, and weather records are often the difference between a successful claim and a dismissed one. Polish arbitral practice has increasingly adopted document production procedures modelled on IBA Rules on the Taking of Evidence. Parties that cannot produce contemporaneous records face adverse inferences.

Specific transaction structures matter here. A foreign investor buying into a Polish project company should conduct FIDIC contract due diligence before closing – examining the claims register, DAAB appointment status, and any pending notices of dissatisfaction. Undisclosed FIDIC claims can represent material contingent liabilities that affect deal pricing.

Frequently asked questions

Q: Can a Polish court enforce a DAAB decision before the arbitration is complete?

A: Yes. Under the 2017 FIDIC conditions, a binding DAAB decision must be complied with immediately. Polish courts have granted enforcement of binding DAAB decisions as contractual obligations under the Civil Code, treating non-compliance as a breach of contract. The claimant should bring a separate summary claim for the undisputed amount rather than waiting for the full arbitral award. This approach is particularly effective where the DAAB decision covers a defined payment obligation rather than a factual finding.

Q: How long does a full FIDIC dispute cycle take in Poland, from Engineer determination to arbitral award?

A: From the Engineer's 42-day determination window through DAAB (84 days), notice of dissatisfaction (28 days), amicable settlement (56 days), and ICC arbitration (24 to 36 months), the full cycle runs approximately 28 to 40 months. This timeline assumes no jurisdictional challenges and a reasonably efficient DAAB process. Delays in DAAB constitution – a common issue in Poland – can add 6 to 12 months before the formal process even begins. Budgeting for this timeline is essential for project finance and cash-flow planning.

Q: Is it possible to skip the DAAB and go directly to arbitration under a FIDIC contract governed by Polish law?

A: Generally, no. The DAAB referral is a condition precedent to arbitration under the 2017 FIDIC suite. An arbitral tribunal seated in Poland will typically decline jurisdiction if the DAAB step has been bypassed without justification. There is a narrow exception: if the DAAB has not been constituted through no fault of the referring party, some tribunals have allowed direct arbitration. This is not a common misconception to rely on – the safer course is always to constitute the DAAB at contract commencement, as the 2017 rules require.
