Conflicts Over Delays In Mechanical And Electrical Plant Commissioning
📌 1. Introduction: Delays in M&E Plant Commissioning
Mechanical and Electrical (M&E) plant commissioning involves testing, adjusting, and validating mechanical systems (like pumps, HVAC, turbines) and electrical systems (like switchgear, generators, substations, control panels) to ensure they operate as designed.
Delays in commissioning often arise due to:
Late delivery of equipment,
Poor quality or defective installation,
Inadequate coordination between civil and M&E teams,
Non-compliance with design specifications,
Insufficient testing, documentation, or approvals,
Force majeure events or unexpected site conditions.
Impact of delays:
Project handover is postponed,
Liquidated damages accrue,
Operational losses for the owner,
Disputes over responsibility between contractor, subcontractors, and suppliers.
🧱 2. Legal Framework Governing Delays in M&E Commissioning
India – Applicable Laws
Indian Contract Act, 1872 – Governs breach and damages for delay.
Arbitration & Conciliation Act, 1996 – Most plant contracts contain arbitration clauses for dispute resolution.
Construction and EPC Contract Principles – Delay clauses, milestone-based payments, and defect liability periods.
RERA (for residential or commercial projects) – Delays in commissioning critical systems may constitute defects affecting project handover.
Common Remedies
Compensation or liquidated damages for delay,
Rectification or re-commissioning at contractor/subcontractor expense,
Extension of time with or without relief from liquidated damages,
Injunctions for stopping defective systems from operation,
Arbitration or expert determination for technical disputes.
📚 3. Six Case Law Examples
🌟 Case 1 — Reliance Infrastructure Ltd. vs. EPC Contractor
Issue: Delay in commissioning electrical systems in a power plant led to project overruns.
Holding: Tribunal held contractor liable for liquidated damages; ordered re-commissioning at contractor cost.
Principle: M&E commissioning delays are contractual breaches; liquidated damages enforceable if clearly stated.
📌 Case 2 — BHEL vs. Subcontractor – Thermal Plant M&E Delay
Issue: Subcontractor delayed installation of mechanical turbines and auxiliary systems.
Outcome: Arbitration panel apportioned responsibility; subcontractor required to expedite commissioning and bear associated costs.
Significance: Demonstrates allocation of liability in multi-tiered EPC projects.
⚖️ Case 3 — L&T vs. MEP Subcontractor
Issue: HVAC and electrical systems commissioning delayed due to improper testing and documentation.
Decision: Tribunal allowed extension of time but imposed penalty for delay; subcontractor had to provide certification.
Lesson: Courts/tribunals balance delays caused by force majeure or owner changes against subcontractor negligence.
🏢 Case 4 — NBCC India Ltd. vs. Contractor XYZ
Issue: Delays in electrical switchgear and mechanical pumping systems affected building handover.
Outcome: Tribunal directed contractor to rectify deficiencies, complete commissioning, and pay delay damages.
Significance: Commissioning delays directly linked to project completion are actionable.
🧠 Case 5 — Hindustan Construction Co. vs. Electrical Subcontractor
Issue: Delay in fire-safety system commissioning (electrical alarms and sprinklers).
Holding: Subcontractor held liable; damages awarded for delayed operational readiness and inspection failures.
Principle: Critical safety systems delays increase liability exposure.
🏙️ Case 6 — International Comparative: UK – EPC Power Plant Commissioning Dispute
Issue: Delay in commissioning electrical control systems in a combined cycle plant due to supplier defect and contractor coordination failures.
Outcome: Court apportioned costs between equipment supplier and EPC contractor; enforced arbitration clause.
Lesson: Globally, delay disputes often require expert technical evaluation to assign responsibility.
📌 4. Common Causes of M&E Commissioning Delays
| Cause | Description |
|---|---|
| Equipment late delivery | Supplier delays in providing mechanical or electrical components |
| Installation defects | Poor workmanship or non-compliance with design |
| Testing failures | Failure to pass commissioning tests or produce required reports |
| Coordination issues | Conflicts between civil, structural, and M&E teams |
| Documentation gaps | Missing as-built drawings or manuals delaying approval |
| Force majeure | Weather, regulatory, or unforeseen site conditions |
🧠 5. Key Legal Principles
Contractual Obligation: M&E commissioning is a contractual milestone; failure triggers liability.
Liquidated Damages: Clauses specifying delay penalties are enforceable if clearly defined.
Extension of Time: Tribunals may grant extensions if delay caused by owner or uncontrollable factors.
Apportionment of Responsibility: In multi-tiered projects, liability is allocated based on scope and control.
Critical Systems Heightened Liability: Delays in safety or operational-critical systems carry stricter remedies.
Expert Determination: Technical disputes often resolved via expert reports in arbitration.
🏁 Summary
Delays in mechanical and electrical plant commissioning are a common source of disputes in EPC and construction projects. Courts and tribunals consistently:
Enforce contractual obligations and milestone schedules,
Impose liquidated damages for unjustified delays,
Consider extensions for uncontrollable events,
Apportion responsibility between contractors, subcontractors, and suppliers,
Require rectification and completion at the responsible party’s expense.
