Construction & Commissioning Support
Bridging construction completion and commissioning sequences with structured pre-startup verification.
Independent Technical representation & Field Support
The transition from construction completion to pre-commissioning is the primary source of project delays. Out-of-sequence handovers, system boundary confusion, and unorganized punch-listing lead to friction between construction and commissioning teams, delaying hot startup.
Kafaah provides field-tested engineers who integrate with EPC construction teams to align progress with commissioning priorities. We divide the plant into logical, commissionable subsystems, compile punch-lists, and manage system handovers.
Scope of Deliverables & Core Execution
Deliverable 01
Defining system boundaries, markup of P&IDs, and subsystem commissionability analysis
Deliverable 02
Developing pre-commissioning test packages (hydro-testing, flushing, air-blowing)
Deliverable 03
System-by-system mechanical completion walkdowns and punch-list generation
Deliverable 04
Verification of piping cleanliness, instrument calibrations, and valve alignments
Deliverable 05
Management of construction-to-commissioning handover documentation and boundary control
Deliverable 06
On-site field safety audits, safety-barriers validation, and initial loop check tracking
Service Engagement & Execution Workflow
System Boundary Definition
Markup P&IDs to divide the plant into distinct, commissionable packages (by system, not just area).
Pre-Commissioning Setup
Draft detailed protocols for piping flushes, chemical washes, mechanical tests, and loop checking.
Walkdown & Punch-listing
Perform joint inspections with construction and owner teams to list outstanding tasks (Category A/B/C).
System Turnover Tracking
Manage the sign-off of mechanical completion dossiers, ensuring all test sheets are compiled.
Pre-Startup Verification
Oversee loop checks, valve configurations, safety equipment readiness, and pressure tests.
Proven Field Capabilities & Technical Depth
Commissioning-Driven Construction: We guide construction teams to finish systems in the exact order required for a logical startup sequence.
Field Integrity: We perform thorough inspects of complex piping, critical refractory installations, and specialized chemical liners.
Critical Risks Managed & Mitigated
Out-of-Sequence Completion
Prevent construction teams from finishing non-critical systems first, which leaves the main commissioning path blocked.
Outstanding Category A Defects
Ensure no critical safety or pressure containment items remain unresolved before piping is pressurized.
Piping Internal Contamination
Avoid damage to compressors, pumps, and catalyst beds by enforcing rigorous piping flushing and blowing protocols.
