Commissioning—the process of verifying that building systems perform as designed—is one of construction's most coordination-intensive phases. Last planner system software provides the planning framework needed to execute commissioning successfully.
Why Commissioning Needs Last Planner
Commissioning challenges that collaborative planning addresses:
Sequence dependency: Tests must happen in order.
Multi-system: Systems interact during testing.
Coordination intensive: Many parties involved.
Time critical: Often on critical path to occupancy.
Lookahead schedule software manages commissioning complexity.
Commissioning Prerequisites
Work that must be complete before commissioning:
Installation: Systems fully installed.
Startup: Equipment energized and running.
Point-to-point: Controls verified connected.
Documentation: As-built information available.
Weekly work plan construction sequences prerequisites.
System-by-System Planning
Plan commissioning for each major system:
HVAC: Air handling, controls, balancing.
Electrical: Power, emergency, lighting.
Plumbing: Domestic water, waste, gas.
Fire protection: Sprinkler, alarm, smoke control.
3 week lookahead schedule details system testing sequences.
Integrated Systems Testing
Testing systems working together:
Fire alarm and HVAC: Smoke mode testing.
Electrical and fire: Emergency power transfer.
BMS integration: All systems communicating.
Sequences: Complete operating sequences.
Construction lookahead software coordinates integrated testing.
Coordination with Trades
Multiple trades supporting commissioning:
Mechanical: HVAC contractor present.
Electrical: Electrical contractor present.
Controls: BMS contractor running sequences.
TAB: Testing and balancing technicians.
Subcontractor management software coordinates commissioning attendance.
Commissioning Authority Coordination
Working with commissioning agents:
Schedule alignment: CxA availability.
Documentation: Required submittals to CxA.
Witness: Tests requiring CxA presence.
Issues: Resolution of commissioning issues.
4 week lookahead schedule includes CxA milestones.
Documentation Requirements
Extensive documentation in commissioning:
Pre-functional: Checklists before functional testing.
Functional tests: Test procedures and results.
Issues logs: Problems found and resolved.
Final reports: Commissioning completion documentation.
Field management software manages commissioning documentation.
Issue Resolution Planning
Problems found during commissioning:
Identification: Issues documented during testing.
Assignment: Responsibility for resolution.
Scheduling: Corrections in lookahead.
Verification: Re-testing after correction.
Rolling lookahead schedule includes issue resolution.
Training Coordination
Owner training during commissioning:
Scheduling: Training sessions in lookahead.
Documentation: Training materials ready.
Participants: Right owner personnel present.
Recording: Video documentation of training.
Look ahead schedule construction includes training milestones.
Seasonal Considerations
Testing dependent on conditions:
Heating: Cold weather for heating tests.
Cooling: Hot weather for cooling tests.
Deferred: Tests that must wait for conditions.
Substitutes: Alternative test methods when needed.
6 week lookahead schedule plans seasonal testing.
Authority Having Jurisdiction
Inspections during commissioning:
Fire marshal: Fire and life safety testing.
Building inspector: Final inspections.
Health department: Commercial kitchen testing.
Elevator: Elevator inspections.
Construction schedule app tracks inspection scheduling.
Enhanced Commissioning
For LEED or high-performance buildings:
Extended testing: Additional test requirements.
Review periods: Design review phases.
Monitoring: Post-occupancy monitoring.
Documentation: Enhanced documentation needs.
Foreman scheduling app coordinates enhanced requirements.
Commissioning Milestones
Key commissioning schedule milestones:
Pre-functional complete: Ready for functional testing.
Functional complete: Systems verified.
Integrated complete: Systems working together.
Final report: Commissioning documentation complete.
Project management software for construction tracks commissioning milestones.
Resource Planning
Resources needed for commissioning:
Personnel: Qualified technicians.
Equipment: Test equipment and instruments.
Time: Protected time for testing.
Access: Access to all spaces.
Crew scheduling software construction manages commissioning resources.
Punch List Integration
Commissioning and punch list coordination:
Priority: Commissioning items first.
Sequencing: Complete before final punch.
Access: Testing before finish work.
Coordination: Don't damage finishes during testing.
Construction software integrates commissioning and punch.
Closeout Coordination
Commissioning as part of closeout:
O&M manuals: Include commissioning documentation.
Warranty: Commissioning validates warranty items.
Training: Training completes before occupancy.
Turnover: Systems ready for owner operation.
Conclusion
Last planner system software provides the coordination framework commissioning demands. System sequences, multi-trade coordination, documentation, and issue resolution all benefit from collaborative planning discipline.
Start commissioning planning early. Your weekly work plan construction should include commissioning activities as soon as systems are being installed.
