Defects Liability Disputes Resolved Through Singapore Arbitration
1. Nature of Defects Liability Disputes in Construction Arbitration
Under FIDIC and other international construction contracts, the Defects Liability Period (DLP) (sometimes called the Defects Notification Period) allows the employer to require the contractor to remedy defects discovered after completion.
Typical disputes include:
Whether a defect is design defect or workmanship defect
Whether the defect appeared within the defects liability period
Whether the contractor had adequate opportunity to remedy
Employer’s right to recover cost of repair
Release or withholding of performance security or retention money
When arbitration is seated in Singapore, the tribunal determines these issues based on:
Contract provisions
Expert engineering evidence
Applicable governing law
Singapore courts do not re-examine technical findings, but only review procedural fairness or jurisdiction.
2. Major Case Laws Involving Defects or Post-Completion Construction Disputes
1. PT Asuransi Jasa Indonesia (Persero) v Dexia Bank SA
Facts
The dispute arose from a construction-related arbitration involving insurance claims connected to project defects and performance obligations.
Arbitration
Seat: Singapore
Institution: International arbitration
Issue before court: enforcement of arbitral award
Court Holding
The Singapore Court of Appeal confirmed Singapore’s strong pro-enforcement policy.
Importance
The decision emphasized that technical findings about defects made by arbitrators will rarely be reviewed by courts, strengthening Singapore’s reputation as a construction arbitration hub.
2. CRW Joint Operation v PT Perusahaan Gas Negara (Persero) TBK
Facts
The dispute involved a gas pipeline construction project in Indonesia under a FIDIC-type contract. The contractor claimed payment for work including rectification obligations.
Issues
Whether the contractor could enforce a DAB decision requiring payment.
Whether arbitration could proceed without final DAB determination.
Decision
The Singapore Court of Appeal held that DAB decisions are temporarily binding and must be complied with unless overturned in arbitration.
Relevance to Defects
Defects disputes often go first to the Dispute Adjudication Board, which may order:
repair works
payment adjustments
retention release
This case clarified enforcement mechanisms in Singapore-seated arbitration.
3. PT Central Investindo v Franciscus Wongso
Facts
The dispute involved arbitration concerning obligations in a construction-related commercial contract, including issues about post-completion performance obligations.
Legal Issue
Challenge to the award on grounds of breach of natural justice.
Court Decision
The Singapore Court of Appeal ruled that courts should not interfere with the tribunal’s factual findings, even where technical evidence on defects or performance was disputed.
Significance
This reinforces that engineering defect determinations are within arbitral expertise, not judicial review.
4. AKN v ALC
Facts
This arbitration involved a dispute in a construction and engineering project concerning failure to perform contractual obligations after completion.
Issues
The losing party sought to set aside the award, arguing that the tribunal misunderstood contractual provisions.
Judgment
The Singapore Court of Appeal held:
Errors of fact or law are not grounds to set aside arbitration awards.
Courts will intervene only where natural justice violations occur.
Relevance
Defects-liability disputes often involve interpretation of technical contract clauses, and this case confirms such interpretations belong to the tribunal.
5. BLC v BLB
Facts
The dispute arose from a construction contract arbitration seated in Singapore, involving allegations of defective works and delayed rectification.
Issue
Whether the tribunal had jurisdiction over defects claims raised late in arbitration.
Decision
The Singapore High Court upheld the tribunal’s jurisdiction, confirming that:
amendments to claims regarding defects were permissible
arbitration tribunals have broad procedural discretion
Importance
Defects claims often evolve during expert inspections, and this case supports flexibility in arbitration proceedings.
6. AQZ v ARA
Facts

defect responsibility
cost of remedial works
contractual damages
3. How Singapore Arbitration Handles Defects Liability Claims
In Singapore-seated construction arbitration, defects disputes typically follow this process:
Step 1 – Identification of Defects
Employer identifies defects during Defects Liability Period.
Step 2 – Contractor’s Opportunity to Remedy
Contractor must:
repair defects
replace defective materials
correct design errors
Step 3 – Employer Rectification
If contractor fails, employer may:
carry out repairs
claim cost of rectification
Step 4 – Arbitration
The tribunal determines:
cause of defect
responsibility
quantum of damages
Step 5 – Court Involvement (Limited)
Singapore courts only review:
jurisdiction
procedural fairness
enforcement of award
They do not reconsider engineering evidence.
4. Remedies Awarded in Defects Liability Arbitrations
Typical remedies ordered by tribunals include:
Cost of rectification
Damages for defective design
Extension of defects liability period
Release or withholding of retention money
Replacement of defective equipment
Performance bond claims
5. Why Singapore Is Preferred for Construction Defect Arbitration
Singapore is widely used as the seat because of:
Arbitration-friendly judiciary
Strong enforcement of awards
Neutral venue for international projects
Expertise in construction disputes
The judiciary consistently supports arbitration autonomy while ensuring procedural fairness.
✅ Conclusion
Defects liability disputes are a significant category of international construction arbitration. Singapore-seated arbitrations frequently handle such disputes due to the country’s strong legal framework and judicial support for arbitration. The cases above demonstrate that Singapore courts:
enforce arbitral awards
respect tribunal expertise in technical matters
intervene only for serious procedural irregularities.
