Managing Variations, Delays and Payment Claims

Construction projects depend on clear contracts, effective project management and timely decisions. Yet even well-planned projects can encounter unexpected changes, delayed approvals, payment disputes, design issues and disagreements over contractual responsibilities.

For developers, contractors, consultants and investors in the UAE, these issues can have significant commercial consequences. A variation that is not properly documented, a delay that is not notified in accordance with the contract, or a payment claim that lacks supporting records can quickly become a contractual dispute.

Effective construction contract management begins before problems arise.

Understanding contractual obligations, following the correct procedures and maintaining reliable project records can help parties manage risk, protect their contractual rights and support successful project delivery.

WHY CONSTRUCTION CONTRACT MANAGEMENT MATTERS

Construction contracts establish the commercial and legal framework for a project. They typically address the scope of work, programme, payment arrangements, responsibilities, variations, extensions of time, defects, termination and dispute resolution.

However, signing a contract is only the beginning.

Throughout the project, parties must administer the contract properly, comply with applicable notice requirements, document decisions and respond to changing circumstances.

Weak contract administration can create problems even where a party has a legitimate contractual entitlement.

For example, a contractor may have incurred additional costs because of a design change but may struggle to recover those costs if the contractual variation procedure was not followed. Similarly, a developer may face difficulties assessing a delay claim if the relevant records are incomplete.

A structured approach to construction contract management helps reduce these risks.

1. UNDERSTAND THE CONTRACT BEFORE WORK BEGINS

The first step is to understand the contract and the obligations it imposes on each party.

Construction contracts may be based on FIDIC forms, bespoke agreements, EPC arrangements, design-and-build contracts or other contractual structures.

Before work begins, the parties should review:

• Scope of work and technical specifications
• Contract drawings and bills of quantities
• Contract price and payment terms
• Commencement and completion dates
• Milestones and project programme
• Variation and change procedures
• Extension of time provisions
• Delay damages and other remedies
• Notice requirements and contractual deadlines
• Defects and warranty obligations
• Suspension and termination rights
• Governing law and dispute resolution provisions

The parties should also identify inconsistencies between the main agreement, appendices, technical specifications, schedules and other incorporated documents.

Where documents conflict, the contractual order of precedence and applicable interpretation rules may become important.

A contract review at the beginning of a project can help identify these issues before they affect performance.

2. MANAGING VARIATIONS AND CHANGE ORDERS

Variations are common in construction projects. They may arise from design revisions, changes in specifications, additional work, site conditions, regulatory requirements or instructions from the employer or its representative.

Although a variation may be commercially necessary, it can create uncertainty regarding scope, price and completion time if it is not properly managed.

What should a variation address?

Depending on the contract, the parties should consider documenting:

• The description and scope of the change
• The reason for the variation
• The person authorised to instruct or approve it
• The effect on the contract price
• Any extension of time required
• The impact on resources and sequencing
• Supporting quotations and cost records
• The effect on other contractual obligations
• The required approval and implementation process

Why written approval matters

A verbal instruction or informal message may not adequately establish the contractual status of additional work.

The parties should follow the contract’s procedures for instructions, quotations, approvals and variation orders. Where urgent circumstances require immediate action, the relevant contract should be checked to determine the appropriate procedure and how the instruction should be recorded.

Contractors should avoid assuming that all additional work will automatically be paid for simply because it was performed.

Developers should likewise ensure that changes are assessed and authorised through the appropriate contractual channels.

Practical point: Maintain a variation register showing each proposed change, its status, approval date, cost impact, time impact and supporting documentation.

3. MANAGING DELAYS AND EXTENSIONS OF TIME

Delays can arise from many sources, including late access to the site, design changes, delayed approvals, late information, variations, supply-chain disruption, unforeseen site conditions and contractor performance issues.

The contractual consequences depend on the circumstances, the applicable contract and the evidence available.

Identify the cause of the delay

A delay should not be assessed solely by reference to the completion date.

The parties may need to examine:

• The contractual programme and approved updates
• The activity affected by the event
• Whether the affected activity was critical to completion
• The cause and duration of the delay
• The parties’ respective contractual responsibilities
• Any concurrent or overlapping delays
• Mitigation measures
• The effect on completion milestones

A proper assessment can help distinguish between delays that may justify an extension of time and delays for which a party may remain contractually responsible.

Comply with notice requirements

Many construction contracts contain specific procedures for notifying delay events and submitting extension of time claims.

These procedures may prescribe the required form, recipient, supporting information and time for notification.

The relevant contract must be checked carefully. Parties should not assume that informal correspondence or a general progress report satisfies a contractual notice requirement.

Maintain contemporaneous records

Useful records may include:

• Daily site reports
• Updated construction programmes
• Meeting minutes
• Site instructions
• Correspondence
• Design submissions and approvals
• Delivery records
• Photographs
• Resource and productivity records
• Weather records where relevant
• Records of mitigation measures

These documents can be important when assessing the cause, duration and consequences of a delay.

4. PAYMENT CLAIMS, CERTIFICATION AND RETENTION

Payment disputes can place considerable pressure on construction projects. Delayed payments may affect cash flow, subcontractor payments, procurement, labour and the overall programme.

The contract should establish a clear process for valuing work, submitting applications, assessing claims, issuing certificates where applicable and making payments.

Review the payment mechanism

Depending on the contractual arrangement, payment provisions may cover:

• Advance payments
• Interim payment applications
• Measurement and valuation
• Milestone payments
• Payment certification
• Variations
• Retention
• Deductions and set-off
• Final accounts
• Supporting invoices and records
• Payment deadlines
• Disputed amounts

The parties should understand the documents required to support each payment application and the procedure for addressing disputed items.

Maintain complete supporting records

A payment claim may require more than an invoice.

Depending on the contract, relevant evidence may include approved measurements, progress reports, variation records, delivery notes, inspection records, certificates and other supporting documents.

Contractors should maintain an organised record of submitted applications, amounts certified, payments received, disputed deductions and outstanding balances.

Developers and employers should likewise maintain clear records of assessments, approvals, reasons for disputed items and payments made.

Address retention and final accounts

Retention and final account provisions should be reviewed carefully.

The contract may specify when retained amounts become due, what conditions apply to their release and how outstanding variations, defects or other adjustments are to be addressed.

The parties should avoid leaving final account reconciliation until the very end of the project. Regular review can help identify unresolved issues before they become more difficult to settle.

5. CONTRACTUAL NOTICES AND CORRESPONDENCE

Contractual notices can be critical to preserving rights and complying with the agreed procedures.

Depending on the contract, notices may relate to delay, variations, payment, defects, suspension, termination or other events.

A practical notice management system should identify:

• The event triggering the notice
• The applicable contractual provision
• The notice deadline
• The required recipient
• The permitted method of service
• The information to be included
• Supporting records
• Follow-up submissions and responses

The parties should use the notice and communication procedures specified in the contract rather than relying on assumptions about how a notice should be delivered.

Why informal communication can be risky

Project teams frequently communicate through email, messaging applications and site meetings. Such communications may be relevant evidence, but they should not automatically be treated as substitutes for formal contractual notices.

A disciplined approach should distinguish routine project correspondence from communications intended to exercise contractual rights or satisfy a formal notice requirement.

6. SUBCONTRACTORS, CONSULTANTS AND SUPPLIERS

Construction projects often involve several contractual relationships operating simultaneously.

The main contract may be supported by subcontractor agreements, consultant appointments, procurement contracts, supply agreements and specialist service arrangements.

Problems can arise when these agreements do not align.

For example, the main contractor may be subject to a particular completion deadline while its subcontractor operates under different milestones or notice requirements. A delay in the subcontract may then affect the main contractor’s performance of its obligations to the employer.

The parties should review whether key provisions are appropriately coordinated, including:

• Scope and technical requirements
• Programme and milestones
• Notice requirements
• Variations
• Payment arrangements
• Defects and warranties
• Indemnities and liability
• Insurance obligations
• Suspension and termination
• Dispute resolution

Contractual coordination cannot eliminate every project risk, but it can reduce gaps between the obligations owed under related agreements.

7. DEFECTS, WARRANTIES AND COMPLETION

Defects and incomplete works can create disputes over responsibility, rectification costs, handover and payment.

The contract should establish the procedures for inspections, testing, completion, handover, defect notification and rectification.

Project teams should maintain clear records of:

• Inspections and test results
• Outstanding works
• Defect notices
• Rectification instructions
• Completion documentation
• Handover records
• Warranty documents
• Maintenance obligations
• Outstanding payment and retention items

The parties should distinguish between contractual completion requirements, any applicable defects notification or rectification period, and other legal obligations that may apply.

The precise rights and responsibilities will depend on the contract and the applicable law.

8. TERMINATION AND SUSPENSION

Suspension and termination can have significant financial and operational consequences.

A party considering either action should first review the relevant contractual provisions and the circumstances giving rise to the proposed action.

Relevant considerations may include:

• The contractual ground for suspension or termination
• Notice and cure requirements
• Required approvals
• Outstanding payments
• Site security and protection of completed work
• Materials and equipment
• Subcontractor arrangements
• Records and handover
• Valuation of work performed
• Potential damages or other remedies

A party should not assume that a contractual breach automatically permits immediate termination in every circumstance.

The relevant procedure, applicable law and potential consequences should be assessed before action is taken.

9. CONSTRUCTION CLAIMS AND DISPUTE PREVENTION

Many construction disputes develop gradually.

A disagreement over a variation may become a payment dispute. A delay claim may lead to disagreement over delay damages. Unresolved defects may affect completion or retention. Over time, several separate issues can become a substantial commercial dispute.

Early identification and documentation of the issues can help the parties assess their positions and explore practical solutions.

A structured claims process

A construction claims process may involve:

1. Identifying the contractual event or issue.
2. Reviewing the relevant contract provisions.
3. Checking applicable notice and submission requirements.
4. Establishing the factual chronology.
5. Gathering supporting documents.
6. Assessing entitlement and potential financial or time consequences.
7. Evaluating the other party’s position.
8. Considering negotiation or settlement.
9. Following the agreed dispute resolution procedure where necessary.

Where specialist technical, delay or quantum analysis is required, appropriate experts may need to be involved.

10. DISPUTE RESOLUTION AND THE UAE LEGAL CONTEXT

Construction contracts should contain a carefully considered dispute resolution mechanism.

Depending on the contract and circumstances, this may involve negotiation, mediation, adjudication where contractually or legally available, arbitration or court proceedings.

The clause should be reviewed for consistency with the contract’s governing law, the chosen forum, any procedural preconditions and the nature of the parties’ relationship.

UAE construction projects may involve different contractual forms, governing laws and dispute resolution arrangements. The appropriate approach should therefore be assessed on the facts of the particular project.

Specific Dubai development: Dubai Law No. 8 of 2025 establishes a dedicated process for certain disputes arising from housing construction contracts involving UAE-national homeowners in Dubai, subject to its scope and jurisdictional requirements. It came into force on 1 January 2026. It should not be assumed to apply to every commercial construction dispute or project. The law’s applicability should be checked against the specific contract and parties.

Where litigation, arbitration representation or another regulated legal service is required, the parties should obtain support from appropriately qualified and authorised counsel.

PRACTICAL CONSTRUCTION CONTRACT MANAGEMENT CHECKLIST

Developers, contractors and project managers should consider the following throughout the project:

• Has the contract been reviewed and understood before work begins?
• Are the scope, specifications and contractual documents consistent?
• Are responsibilities and approval authorities clearly defined?
• Is there a reliable process for managing variations?
• Are delay events documented promptly?
• Are contractual notice deadlines tracked?
• Are payment applications supported by adequate records?
• Are disputed deductions and outstanding amounts recorded?
• Are subcontractor and consultant obligations aligned where necessary?
• Are defects, completion and handover requirements monitored?
• Are contractual correspondence and project records organised?
• Are potential claims identified early?
• Have governing law and dispute resolution provisions been reviewed?

A consistent process helps project teams identify problems earlier and make better-informed commercial decisions.

COMMON MISTAKES IN CONSTRUCTION CONTRACT MANAGEMENT

Proceeding With Changes Without Proper Documentation

Additional work can create disputes if its scope, approval, cost and time consequences are not properly recorded.

Missing Contractual Notice Deadlines

A party may encounter difficulties where it fails to follow applicable notice procedures or submit required information within the contractual period.

Treating Every Delay the Same Way

The cause, effect and contractual allocation of responsibility must be assessed rather than assuming that every delay produces the same legal consequences.

Submitting Incomplete Payment Claims

Missing records or inadequate supporting documentation can delay assessment and create unnecessary disagreements.

Keeping Poor Project Records

Incomplete correspondence, programme updates, approvals and site records can make it harder to establish what happened and when.

Reviewing Disputes Too Late

Allowing contractual disagreements to accumulate can increase financial exposure and make settlement more difficult.
