Kadernani & CompanyA delayed completion date can quickly become more than a scheduling problem. For developers, contractors, investors and lenders, construction delay claims in the UAE can affect liquidated damages exposure, project financing, cash flow, subcontractor claims, revenue forecasts and, ultimately, whether the parties can complete the project without a wider commercial dispute.
The fact that a project finished late does not, by itself, determine liability.
The real questions are usually more difficult: what caused the delay, which party assumed that risk under the contract, whether the event affected the contractual completion date, whether the required notices were issued, and whether the claimed financial consequences can be proved.
On major UAE projects, those questions are often governed by heavily amended FIDIC forms, bespoke EPC agreements, design-and-build contracts, construction management arrangements or developer-specific standard forms. The amendments can materially alter the risk allocation found in the underlying standard form.
A delay claim should therefore begin with the contract actually signed, not with assumptions about what a FIDIC provision normally says or what happened on another project.
The legal framework has also changed. Federal Decree-Law No. 25 of 2025 Promulgating the Civil Transactions Law came into force on 1 June 2026, replacing the previous Civil Transactions Law and introducing updated provisions affecting contracts of works, contractual compensation and the treatment of circumstances that disturb the economic balance of a construction contract.
For ongoing and future UAE projects, delay strategy should therefore be considered against both the contractual framework and the current UAE law.
Construction Delay Claims Begin With Risk Allocation
The first question is not simply whether completion occurred after the contractual date.
It is why completion was delayed and who assumed that particular risk.
An employer-risk event may arise from matters such as delayed site access, late design information, variations, instructions, delayed approvals, suspension or interference with the contractor's planned sequence.
Contractor-risk delay may arise from inadequate mobilisation, labour shortages attributable to the contractor, procurement failures, defective planning, insufficient resources, poor subcontractor performance or defective work requiring correction.
Other events may sit within separate contractual regimes dealing with exceptional events, changes in law, unforeseen physical conditions or circumstances beyond the parties' reasonable control.
The labels themselves are less important than the contractual consequences.
For each alleged delay event, the analysis should identify:
what happened, when it happened, which contractual provision applies, what notice was required, which activity was affected and whether that activity actually influenced contractual completion.
That is the foundation of a credible delay claim.
Time Entitlement and Financial Entitlement Are Different
One of the most important distinctions in construction disputes is the difference between entitlement to additional time and entitlement to additional money.
A contractor may establish that an employer-risk event justified an extension of time without establishing that every additional cost incurred during the extended period is recoverable.
An extension of time may protect the contractor against delay damages for an excused period.
A claim for prolongation costs requires a separate analysis of the contractual entitlement, causation and evidence supporting the costs claimed.
Those costs might include additional site supervision, accommodation, temporary facilities, insurance, plant, utilities and other project overheads that continued because the project remained on site longer than originally anticipated.
Head-office overhead claims require further care.
Formulae may sometimes be used as part of the analysis, but a formula is not a substitute for proving that the relevant contractual event caused a compensable loss.
The same distinction applies from the employer's perspective.
A contractor may have experienced genuine disruption somewhere on the project without that disruption extending the contractual completion date.
Delay, disruption and prolongation should therefore not be treated as interchangeable concepts.
The Contractual Notice Regime Can Be Decisive
Many construction contracts used in the UAE require a party claiming additional time or money to issue notice within a specified period.
The contract may then require further particulars, programme information, contemporary records and a fully detailed claim within additional time limits.
These requirements should be taken seriously.
Whether a failure to comply with a notice provision ultimately prevents recovery will depend on the wording of the clause, the governing law, the nature of the requirement, the parties' conduct and the surrounding facts.
It is nevertheless dangerous to assume that contractual notice requirements can simply be ignored because the employer or engineer already knew there was a problem on site.
Knowledge that a delay event occurred is not necessarily the same as receiving contractual notice that the contractor asserts an entitlement to additional time or money.
The notice should normally make the position intelligible.
It should identify the event, the relevant contractual basis and the relief being preserved, even where the full impact cannot yet be quantified.
Contractors should also avoid waiting until the final account to transform months of project correspondence into a formal delay claim.
By then, the contemporaneous opportunity to document cause and effect may have been lost.
Employers Need the Same Discipline
Notice compliance is not solely a contractor issue.
Employers, engineers and project managers should ensure that responses to claims are equally disciplined.
A response may need to distinguish between:
acknowledging that an event occurred and accepting contractual liability for its consequences.
Project correspondence should therefore be reviewed carefully.
A statement intended merely to keep work moving can later be relied upon as evidence of acceptance, waiver or agreement if it is drafted without sufficient precision.
Where entitlement is disputed, the employer can still direct mitigation, request further particulars or maintain progress while reserving its contractual position.
The commercial objective should be to keep the project moving without accidentally determining a claim through informal correspondence.
The 2026 Civil Transactions Law Changes the Legal Background
The current UAE Civil Transactions Law deserves particular attention in construction matters.
The law expressly modernises the provisions governing contracts of works and places greater emphasis on the contractor's responsibilities during execution.
Among the matters addressed by the updated framework are performance within the agreed period or, where appropriate, a reasonable period; notification of defects or circumstances obstructing execution; remedies where performance does not comply with the contract; and exceptional circumstances capable of disturbing the financial equilibrium of the contract.
This does not replace the parties' detailed construction agreement.
On a major project, the contract will remain central to questions of notice, extension of time, valuation, variations, claims procedure and dispute resolution.
The statutory framework nevertheless forms part of the legal environment in which those contractual rights are interpreted and enforced.
For projects commenced under earlier legislation, the applicable temporal and transitional position should be considered carefully rather than assuming that every event is governed identically.
Liquidated Delay Damages Require a Current UAE Law Analysis
Construction contracts frequently specify an agreed amount payable for each day or week that completion is delayed beyond the contractual completion date.
These provisions are commonly described as liquidated damages, delay damages or agreed compensation.
They provide commercial certainty by establishing the financial consequence of culpable delay without requiring the employer to prove its loss from the beginning in every case.
However, agreed delay damages in a UAE-law contract should not be viewed as entirely insulated from judicial review.
Under Article 340 of the current Civil Transactions Law, contracting parties may determine compensation in advance.
The law also gives the court power to reduce agreed compensation where the debtor proves that the amount is excessive or that the underlying obligation has been partly performed.
The court may also reduce compensation where the creditor's own fault contributed to the occurrence or increase of the damage and may decline compensation where the creditor's fault predominates.
Conversely, the creditor may seek compensation above the agreed amount where fraud or gross fault is established.
For construction disputes, this makes the factual delay analysis particularly important.
An employer seeking delay damages should be able to establish the period of contractor-responsible delay and address any employer-caused events affecting the same completion period.
A contractor resisting delay damages should not rely only on an assertion that the agreed rate is too high.
The relevant contractual, factual and financial evidence should be examined against the current statutory test.
An Extension of Time Can Affect Delay-Damages Exposure
Where the contractor establishes entitlement to an extension of time, the contractual completion date is generally adjusted in accordance with the contract.
That adjustment can directly affect the period against which delay damages are calculated.
This makes the extension-of-time mechanism fundamental to both parties.
For the contractor, a properly established extension may protect against delay-damages exposure for an excused period.
For the employer, an extension-of-time mechanism can preserve a workable contractual completion regime where qualifying employer-risk events occur.
The analysis should be performed event by event rather than by simply comparing the original completion date with the date of actual completion.
Causation Is the Core of a Delay Claim
A delay event does not automatically justify an extension of time because it occurred during the project.
The claimant must ordinarily demonstrate a sufficient causal relationship between the event and the contractual delay for which relief is sought.
This is where programme analysis becomes important.
A convincing delay case should connect the alleged event to the activities affected and explain how those activities influenced the route to contractual completion.
The relevant evidence can include:
the accepted baseline programme, contemporaneous programme updates, progress records, meeting minutes, instructions, drawings, procurement schedules, site reports and correspondence.
The objective is to demonstrate what should have happened, what actually happened and why the completion date moved.
The analysis should not begin with a desired number of delay days and work backwards toward an explanation.
It should begin with the project record.
Critical Path Analysis Needs Reliable Data
The concept of the critical path is central to many delay claims because a delay to a non-critical activity may have no effect on contractual completion if sufficient float or alternative sequencing remains available.
But critical-path analysis is only as reliable as the underlying programme information.
Complex UAE projects frequently involve revised programmes, multiple work fronts, sectional completion dates and acceleration or resequencing during execution.
Programme logic may not always reflect what actually occurred on site.
An expert should therefore not treat the scheduling software as though it independently proves causation.
The programme analysis should be tested against contemporaneous evidence.
If a programme indicates that one activity controlled completion while daily reports and site records show that work proceeded differently, the inconsistency requires explanation.
Good delay analysis combines technical scheduling evidence with an understanding of how the project was actually built.
The Appropriate Delay Method Depends on the Dispute
There is no single delay-analysis method appropriate for every claim.
A prospective analysis performed while the project is underway may assess how an event was reasonably expected to affect completion at that time.
A retrospective analysis conducted after substantial progress or completion can consider what actually occurred.
Other methodologies may examine windows of project performance, planned versus actual progress or the effect of specific events on the programme.
The appropriate methodology depends on the contract, records, stage of the project and question the expert is being asked to answer.
The method should serve the facts.
The facts should not be manipulated to fit the method.
Concurrent Delay Requires Particular Care
Concurrent delay remains one of the most difficult areas of construction disputes.
The phrase is often used too loosely.
Two delay events occurring during the same calendar period are not necessarily concurrent in the legally or technically relevant sense.
The important issue is whether separate events for which different parties carry responsibility actually affected critical progress during the same relevant period.
A genuine concurrency analysis should therefore distinguish between:
true concurrent critical delay, sequential delays, overlapping events affecting different work fronts and events that existed at the same time but had no effect on contractual completion.
The consequences of concurrency will depend heavily on the contract and the particular factual analysis.
There is no sensible basis for assuming that every UAE project should apply one universal concurrency formula regardless of its wording.
Concurrency may affect extension-of-time entitlement, delay damages and prolongation costs differently.
The position should therefore be analysed separately for each head of relief.
Multiple Sections and Milestones Complicate Delay Analysis
Large UAE developments often contain several completion obligations.
There may be:
sectional completion dates, phased handovers, access milestones, authority-approval dates, testing milestones or obligations connected with specific buildings or zones.
A delay to one part of the development may therefore have no effect on another.
Claims should be analysed against the contractual milestone actually affected.
This becomes particularly important where delay damages are stated separately for different sections.
A global assertion that the “project was delayed by 120 days” may conceal substantially different causation across different parts of the works.
Variations Need Both Valuation and Time Analysis
Variations are a common source of delay claims.
The fact that additional work was instructed does not automatically establish the number of days to which the contractor is entitled.
The variation should be considered against:
when it was instructed, what work changed, what resources were required, which programme activities were affected and whether the work altered the critical path.
Repeated small variations can sometimes create a cumulative effect even where no individual instruction appears substantial.
That cumulative case requires careful evidence.
Contractors should therefore avoid limiting variation records to valuation alone.
The time consequences should be recorded while the project is live.
Employers should similarly distinguish between the cost of the varied work and any alleged impact on completion.
Late Information and Approvals Should Be Measured Against When They Were Actually Needed
Another common delay allegation concerns late drawings, approvals or decisions.
It is not enough to show that information was issued later than an administrative schedule suggested.
The relevant question is often whether the information was provided later than the date on which it was reasonably required to avoid affecting the works.
That may require examination of:
design schedules, procurement lead times, construction sequence, submittal logs and contemporaneous requests for information.
A drawing issued late in calendar terms may have caused no actual delay if the related work was not ready to proceed.
Conversely, a relatively short approval delay can have significant consequences if it affects a critical procurement or mobilisation decision.
Timing should therefore be analysed in context.
Prolongation Costs Should Follow the Period of Compensable Delay
A credible prolongation claim should identify the additional period for which compensation is sought and the costs actually associated with that period.
Potential cost categories can include:
site management, supervision, temporary facilities, plant, accommodation, utilities, insurance and other time-related project costs.
The claim should distinguish between costs genuinely extended because of the compensable delay and costs that would have been incurred regardless of that event.
This is particularly important where the contractor was simultaneously experiencing its own delays.
Accounting records should correspond with the delay analysis.
A scheduling report showing additional time and a spreadsheet showing additional cost are not enough if the two cannot be connected.
Disruption Is Different From Prolongation
A project can become less productive without finishing later.
Repeated resequencing, restricted access, multiple changes or fragmented work fronts may cause labour and equipment inefficiency even where the contractor ultimately protects the completion date.
That is a disruption issue rather than simply a prolongation claim.
Disruption claims can be difficult because they require a credible comparison between expected and actual productivity and an explanation of why the difference resulted from compensable events rather than contractor inefficiency.
Contemporaneous productivity records become particularly important.
Labour numbers alone rarely tell the whole story.
The records should show what crews were expected to perform, what conditions they encountered and how output changed.
Acceleration Should Be Documented Before Costs Escalate
Acceleration often develops because the employer insists that the contractual completion date remains unchanged while the contractor believes it has encountered excusable delay.
The contractor may respond by increasing labour, adding shifts, resequencing works or expediting materials.
If the parties do not address the contractual basis for those measures at the time, a substantial dispute may arise later over who must pay.
Before significant acceleration expenditure is incurred, the parties should clarify:
whether acceleration has been instructed, whether it is voluntary mitigation, what completion objective is being pursued and how additional costs will be recorded and valued.
An informal instruction to “recover the delay” can become commercially expensive if the parties attach different meanings to it.
Mitigation Should Be Practical and Documented
A party affected by delay should consider reasonable measures capable of limiting unnecessary escalation of time and cost.
Depending on the project, this may involve:
resequencing, alternative procurement, partial access, additional resources or revised handover arrangements.
The appropriate step will depend on the contract and the circumstances.
Under the current UAE Civil Transactions Law, the conduct of the party claiming compensation can also matter because Article 340 permits reduction where the creditor's own fault contributed to the occurrence or increase of the damage.
This provides another reason to document mitigation decisions carefully.
A party should be able to explain not merely that additional cost was incurred, but why the chosen response was reasonable in the circumstances.
Exceptional Circumstances Now Have a More Specific Statutory Role
The 2026 Civil Transactions Law also modernises the treatment of exceptional circumstances affecting contracts of works.
The new framework recognises that unexpected general circumstances may disturb the economic equilibrium upon which a construction contract was based and gives the court powers, where the statutory conditions are met, to restore balance through measures that may include adjustment of the price, extension of the performance period or termination.
This is a significant area, but it should not be treated as a general escape route from a commercially difficult contract.
Construction projects routinely experience price changes, procurement difficulties and operational challenges.
The statutory threshold and the specific circumstances must be established.
The contract itself should also be reviewed for provisions dealing with exceptional events, changes in law, price adjustment and similar risks.
Project Records Convert Commercial Position Into Evidence
Delay disputes are often decided years after the relevant event occurred.
The people who managed the project may have moved on.
Memories become less reliable.
Emails are archived or deleted.
Programme files become difficult to locate.
The quality of the contemporaneous record can therefore determine whether a position that was obvious to the project team can later be proved to a tribunal, court or expert.
A well-managed project should preserve records showing:
what work was planned, what work occurred, what prevented progress, who was notified and what additional time or cost resulted.
Daily reports should record meaningful project facts rather than merely repeating generic descriptions.
Meeting minutes should identify outstanding decisions and responsibility.
Instructions should be retained.
Programme files should be preserved in their native format as well as PDF.
Cost records should allow claimed expenditure to be reconciled against the accounting system.
The objective is not to create documents for litigation.
It is to maintain a reliable project history.
WhatsApp and Informal Communications Can Become Evidence
Modern construction projects generate substantial informal communication.
Project decisions may be discussed through WhatsApp, Teams or other messaging platforms before formal correspondence is issued.
Those communications can later become relevant evidence.
Businesses should therefore ensure that commercially significant directions and agreements are captured properly in the contractual record rather than remaining exclusively within informal messages.
Once a dispute is reasonably foreseeable, relevant electronic communications should also be preserved.
A legal team trying to reconstruct years of project decisions from individual employees' mobile phones begins from an unnecessarily difficult position.
Experts Should Explain the Project, Not Replace the Evidence
Delay experts and quantum experts can play an important role in major construction disputes.
Their value lies in analysing complex information objectively and presenting it in a form that allows the decision-maker to understand causation and loss.
The expert should not be expected to manufacture an entitlement that the contemporaneous documents do not support.
Counsel and experts should therefore work together early enough to identify evidential gaps.
A good technical report should remain consistent with the contractual case.
A good legal case should remain consistent with the technical evidence.
Where they diverge, the problem should be identified before submissions are finalised.
Senior Management Should Know the Real Exposure
Construction disputes can become disconnected from the commercial people responsible for the project.
Legal teams argue entitlement.
Planners argue critical path.
Quantity surveyors argue valuation.
Meanwhile, senior management may not have a clear picture of the overall exposure.
A significant delay claim should therefore be translated into business terms.
Management should understand:
the strongest claims, principal weaknesses, likely delay range, damages exposure, recoverable cost, expected dispute cost, settlement options and effect on project completion.
That allows commercial decisions to be made before positions become unnecessarily entrenched.
Settlement Does Not Require Abandoning Contractual Rights
Many construction delay disputes are best resolved while the project is still live.
The parties may need to continue working together for months or years.
A negotiated arrangement concerning extensions of time, acceleration, milestone revisions or interim payment can sometimes preserve greater value than allowing every issue to accumulate into the final account.
Negotiation should nevertheless be informed.
The parties should understand the contractual position and preserve the evidence supporting it before agreeing commercial compromises.
Without that preparation, settlement negotiations can become a process in which neither side understands what it is giving up.
The Dispute Route Should Be Reviewed Before the Claim Hardens
Where a commercial resolution is not achievable, the dispute-resolution provisions should be reviewed early.
UAE construction contracts may provide for:
court litigation, institutional arbitration, dispute boards, expert determination or tiered procedures requiring negotiation before formal proceedings.
Arbitration clauses frequently refer to institutions such as DIAC or ICC, while international projects may use other institutions.
The relevant questions include:
the governing law, seat of arbitration, tribunal composition, language, pre-arbitration requirements and mechanisms for multi-party or multi-contract proceedings.
The current DIAC Arbitration Rules are the DIAC Arbitration Rules 2022.
ICC introduced revised ICC Arbitration Rules 2026, effective for arbitrations commenced from 1 June 2026 subject to the Rules' applicable provisions.
The procedural route should therefore be checked against the current institutional framework rather than an outdated precedent.
Subcontractor Delay Claims Need to Be Managed Alongside the Main Contract
A main contractor may face an employer claim while simultaneously pursuing corresponding relief against subcontractors.
The two contractual positions are not automatically identical.
Notice requirements, delay-damages provisions, caps and extension-of-time mechanisms may differ between the main contract and subcontract.
A contractor should therefore avoid assuming that recovery from a subcontractor will mirror liability to the employer.
Where possible, the contractual chain should be reviewed together.
The timing of notices and dispute proceedings should also be coordinated so that the contractor does not resolve one claim in a manner that prejudices another.
A Delay Claim Should Be Built While the Project Is Still Alive
The strongest time to assess a construction delay claim is generally when a material event first threatens completion.
At that stage, the project team can still:
issue the required notice, preserve the correct records, update the programme, identify the affected activities, record actual cost and consider realistic mitigation.
Waiting until the final account significantly reduces those opportunities.
The project then becomes an exercise in reconstruction.
A construction lawyer or delay expert brought in early does not necessarily need to turn the project into a dispute.
The opposite is often true.
Early analysis can identify which events genuinely matter, prevent weak claims from distracting the project team and give senior management a clearer basis for commercial negotiations.
A Commercial Approach to Construction Delay Claims in the UAE
The most persuasive construction delay cases tend to be straightforward in concept even when the underlying project is highly complex.
They identify:
the contractual obligation, the delaying event, the party carrying the relevant risk, the required notice, the effect on programme completion and the financial consequence that followed.
Every additional layer of analysis should support that chain.
The objective is not to produce the largest possible claim.
It is to produce a claim or defence that can withstand scrutiny from the other party, the engineer, an expert, a tribunal or a court.
For developers and employers, the same discipline applies when assessing delay damages.
The project record should show why completion was delayed, which periods were contractor-responsible and how any employer-caused events were treated.
For contractors, an extension-of-time claim should demonstrate causation rather than simply identify a long list of events that occurred during the project.
For both sides, the earlier that analysis begins, the greater the ability to preserve commercial options before the dispute becomes the dominant feature of the project.
How Kadernani & Company Legal Consultants Can Assist
Kadernani & Company Legal Consultants provides strategic, commercially focused legal advice to developers, contractors, subcontractors, consultants, investors and project stakeholders involved in construction contracts and disputes throughout Dubai, Abu Dhabi, the wider UAE and international markets.
For professional advice regarding construction delay claims in the UAE, extensions of time, liquidated delay damages, FIDIC contracts, variations, prolongation and disruption claims, acceleration, construction arbitration, DIAC or ICC proceedings and construction contract disputes, contact Kadernani & Company Legal Consultants to discuss the legal and commercial strategy appropriate to the project.
Our approach begins with the project record and the contract actually signed.
Delay disputes should first be reduced to a clear chronology identifying the relevant contractual obligations, notice requirements, alleged delay events, programmed impact, claimed costs and competing causes of delay.
For live projects, early advice can help the project team preserve entitlement without unnecessarily escalating the commercial relationship. Notices, reservations of rights and responses to claims should protect the legal position while allowing the parties to continue addressing completion.
Where delay has already occurred, the legal analysis should be coordinated with appropriate planning and quantum expertise. The contractual case, delay methodology and financial claim should tell the same factual story.
Current UAE law should also form part of the assessment. Following the entry into force of Federal Decree-Law No. 25 of 2025 on 1 June 2026, construction claims should be reviewed against the updated Civil Transactions Law, including the revised provisions affecting contracts of works, agreed compensation and exceptional circumstances.
For employers seeking contractual delay damages, the analysis should address both the agreed damages provision and the current statutory framework governing predetermined compensation.
For contractors seeking an extension of time or prolongation costs, the review should separately examine time entitlement, monetary entitlement, contractual notice compliance, actual critical delay and proof of the resulting costs.
Concurrent-delay allegations require particular scrutiny. Two events occurring during the same period should not be treated as concurrent merely because their dates overlap. The analysis should establish whether each event independently affected critical completion and what contractual consequence follows.
Where settlement is commercially appropriate, a properly developed delay position can provide the basis for a negotiated solution involving extensions of time, revised milestones, acceleration, payment, final-account resolution or other commercial arrangements without surrendering the client's underlying rights unnecessarily.
Where formal proceedings become necessary, the dispute strategy should be coordinated from the contractual claim through expert evidence, arbitration or litigation and eventual enforcement.
A construction delay dispute cannot always be avoided. Its financial and legal consequences can, however, be materially influenced by what the parties do when the first serious delay occurs.
For boards and senior project decision-makers, the practical test is straightforward: the delay position should be capable of explaining what happened, who carried the contractual risk, how completion was affected and what legally recoverable consequence followed.
Where the project records cannot presently answer those questions, a senior-led review while the evidence remains available is usually the more prudent course.
