What Is Payment Certification in Construction?
Payment certification is the process of measuring completed work and issuing payment certificates that authorize progress payments to contractors. In UAE construction, this typically follows FIDIC contract provisions with specific local practices.
Understanding and managing this process efficiently is critical for project cash flow and stakeholder relationships.
The UAE Payment Certification Workflow
Step 1: Progress Measurement
Contractor prepares claim based on work completed:
- Measured work against BOQ quantities
- Materials on site (if contractually allowed)
- Variations approved to date
- Preliminary and general items
Step 2: Contractor Application
Contractor submits Interim Payment Application (IPA):
- Cover letter requesting certification
- Detailed breakdown by BOQ section
- Supporting documentation
- Variation claims
- Daywork if applicable
Step 3: Consultant Review
Engineer/quantity surveyor reviews application:
- Verify quantities claimed
- Check against approved variations
- Review supporting documentation
- Site verification as needed
Step 4: Certificate Issuance
Consultant issues Interim Payment Certificate (IPC):
- Certified amount (may differ from claimed)
- Breakdown by category
- Deductions (retention, previous payments)
- Net payment due
Step 5: Client Payment
Client processes payment based on certificate:
- Review and approval
- Payment within contractual timeframe
- Record keeping
Key Components of Payment Certification
Bill of Quantities (BOQ)
The BOQ forms the basis for payment:
- Measured items priced in tender
- Unit rates applied to completed quantities
- Provisional sums for uncertain items
- Daywork rates for additional work
Retention
Percentage withheld to ensure completion:
- Typically 5-10% of certified amounts
- First half released at substantial completion
- Second half at end of defects liability period
- May have cap (e.g., 5% of contract value)
Variations
Changes to contract scope:
- Must be approved before claiming
- Valued per contract variation provisions
- Impact on program considered
- Often contentious area requiring documentation
Preliminaries and General Items
Time-related and method-related costs:
- Site establishment
- Staff costs
- Equipment
- Often certified on time basis
Common Payment Certification Challenges
Quantity Disputes
Problem: Disagreement over measured quantities
Solution: Clear measurement methodology, joint measurements, photo documentation
Variation Valuation
Problem: Disputes over variation pricing
Solution: Timely variation approval, clear basis for valuation, documentation
Late Certification
Problem: Delayed certificate issuance affecting cash flow
Solution: Adherence to contractual timeframes, escalation procedures
Supporting Documentation
Problem: Incomplete or missing documentation delaying certification
Solution: Standardized submission requirements, checklists
Retention Release
Problem: Delayed retention release at completion
Solution: Clear completion criteria, documented handover, timely processing
Best Practices for UAE Payment Management
1. Establish Clear Procedures
Document payment process at project start:
- Submission deadlines
- Required documentation
- Review timeframes
- Approval authorities
2. Maintain Accurate Records
Keep detailed documentation:
- Daily records of quantities
- Photo documentation of progress
- Approved variation orders
- Correspondence on contentious items
3. Submit Complete Applications
Reduce review cycles with complete submissions:
- All required supporting documents
- Clear breakdown and calculations
- Reference to approved variations
- Consistent format
4. Track Progress Systematically
Implement systems for:
- Quantity tracking against BOQ
- Variation register maintenance
- Progress photo documentation
- Issues flagging
5. Communicate Proactively
Address issues before they become disputes:
- Early notification of variation entitlement
- Discussion of measurement methodology
- Resolution of queries promptly
Digital Tools for Payment Certification
Quantity Tracking
Software can automate:
- Progress measurement against BOQ
- Cumulative tracking across certificates
- Balance remaining calculation
- Comparison of claimed vs certified
Variation Management
Digital systems support:
- Variation request workflow
- Approval tracking
- Valuation documentation
- Integration with payment certification
Document Management
Centralized storage enables:
- Payment certificate archive
- Supporting documentation library
- Audit trail of submissions and responses
- Easy retrieval for audits or disputes
Reporting
Automated reporting provides:
- Cash flow forecasts
- Payment status dashboards
- Variance analysis
- Trend tracking
Payment Terms in UAE
Contractual Timeframes
FIDIC-based contracts typically specify:
- Contractor submission: Monthly (by specific date)
- Engineer certification: 28 days from receipt
- Client payment: 56 days from receipt (or per contract)
Late Payment Considerations
Late payment is mainly governed by the contract. FIDIC-based contracts, for example, provide for:
- Financing charges on delayed payment (Sub-Clause 14.8)
- The Contractor's right to suspend work (Clause 16)
- Termination provisions (Clause 16)
Clause numbers differ between FIDIC editions and amended contracts, and whether any statutory interest applies depends on the circumstances under UAE law.
Note: Take legal advice on specific contract terms and disputes.
How Arkan Supports Payment Certification
Arkan's financial modules support efficient payment management:
BOQ management: Upload BOQs from Excel, break items down, and track progress and budget health. See BOQ management.
Variation tracking: Record BOQ variations with their value impact, approval status and comments. See variation management.
Payment requests: Build payment requests in a step-by-step wizard linked to BOQ items and advance payments. See payment certificates, including a worked example from BOQ progress to net payable.
Approval workflow: Route payment requests through appropriate approvers.
Retention and advance payments: Track retention balances and releases, and advance payments and their recovery.
Reporting: A finance dashboard with financial overview cards and analytics, plus Excel and PDF exports.
To check a certificate's arithmetic yourself, use the free IPC calculator and the retention calculator.

Frequently Asked Questions
What is an IPC in construction?
An Interim Payment Certificate (IPC) is a document issued by the engineer/consultant certifying the amount due to the contractor for work completed during a payment period.
How often are IPCs issued?
Typically monthly, with specific dates defined in the contract. The contractor submits an application, and the consultant issues a certificate within the contractual review period.
What is retention in construction contracts?
Retention is a percentage of payments withheld to ensure satisfactory completion. Typically 5-10%, it's released partially at substantial completion and the balance after the defects liability period.
Why do payment certifications get delayed?
Common causes include incomplete documentation, quantity disputes, variation valuation disagreements, and consultant resource constraints.
How can I speed up payment certification?
Submit complete applications with all required documentation, maintain accurate progress records, resolve queries promptly, and implement digital systems for efficient workflow.
Conclusion
Payment certification is critical to construction project cash flow and relationships. Understanding the process, maintaining accurate records, and using digital tools for efficient management helps ensure timely payments and reduces disputes.
