Commissioning Specification

Division 01 contract language that assigns commissioning responsibilities to the contractor and defines submittal, testing, documentation, and training obligations. It makes commissioning requirements enforceable under the construction contract.

Related: Commissioning Plan, Functional Performance Test
Pre-Functional Checklist

A verification form used before energizing or starting equipment to confirm installation matches approved submittals and manufacturer requirements. Completed checklists must be submitted and accepted before functional performance testing begins.

Related: Functional Performance Test, Installation Verification
Functional Performance Test (FPT)

A documented, repeatable procedure that operates a system through specified modes and conditions to demonstrate it meets the owner's project requirements and design intent. Results are recorded, witnessed, and retained as commissioning records.

Related: Pre-Functional Checklist, Test Procedure, Seasonal Testing
Test Procedure

A step-by-step written script listing prerequisites, instrumentation, actions, expected responses, acceptance criteria, and data to record for a functional test. It is reviewed and accepted before execution so results are objective.

Related: Functional Performance Test, Acceptance Criteria
Acceptance Criteria

Predetermined, measurable conditions that a tested system must satisfy for the test to pass. Criteria should be stated in the test procedure and traceable to the owner's project requirements or design documents.

Related: Test Procedure, Functional Performance Test
Commissioning Issues Log

A tracked record of problems, questions, and deficiencies found during commissioning, including owner, location, responsible party, status, and resolution date. It is reviewed at progress meetings until every item is closed.

Related: Deficiency, Design Review
Deficiency

A condition where work does not conform to contract documents, manufacturer instructions, or the owner's project requirements. Deficiencies are documented, assigned to a responsible party, corrected, and retested before acceptance.

Related: Commissioning Issues Log, Retesting
Retesting

Repeating a failed or incomplete test after corrective work to confirm the system now performs as required. Retest results are documented and attached to the original test record for a complete audit trail.

Related: Deficiency, Functional Performance Test
Installation Verification

Systematic confirmation that equipment and systems are installed per approved submittals, manufacturer instructions, and contract documents. It typically uses pre-functional checklists and visual inspection before functional testing.

Related: Pre-Functional Checklist, Submittal Review
Submittal Review

The commissioning team's examination of contractor product data, shop drawings, and samples for compliance with design intent and owner requirements. Comments flag discrepancies early, before equipment is fabricated or installed.

Related: Installation Verification, Basis of Design
Systems Manual

A consolidated reference containing design and as-built information, equipment data, control sequences, operating procedures, and maintenance guidance. It supports efficient operation and is a required commissioning deliverable at handover.

Related: As-Built Documents, Training Plan
Training Plan

A document identifying who needs training, on which systems, in what format, and when, with measurable learning objectives. It is developed early so training content and verification align with the systems manual.

Related: Systems Manual, Handover
Handover

The structured transfer of a completed facility to the owner, including verified systems, closeout documents, the systems manual, training completion, and open-item lists. Successful handover confirms readiness for occupancy and operation.

Related: Systems Manual, Substantial Completion
Substantial Completion

The stage when the work is sufficiently complete for the owner's intended use, triggering warranty start, punch list work, and final commissioning closeout activities. Commissioning status is typically reported at this milestone.

Related: Handover, Punch List
Punch List

A list of minor incomplete or corrective work identified near completion that does not prevent occupancy. Punch items are tracked to closure alongside commissioning issues before final acceptance.

Related: Substantial Completion, Deficiency
Seasonal Testing

Deferred functional testing performed when weather allows verification of heating, cooling, or part-load performance not achievable during initial testing. It is scheduled and budgeted in the commissioning plan.

Related: Functional Performance Test, Commissioning Plan
Retro-Commissioning (RCx)

A commissioning process applied to existing buildings not previously commissioned, focused on tuning and low-cost operational improvements. It typically begins with assessment and investigation rather than design review.

Related: Ongoing Commissioning, Monitoring-Based Commissioning
Ongoing Commissioning

A continuing effort using monitoring, trend analysis, and periodic checks to sustain performance after initial commissioning. It aims to catch drift and faults early rather than waiting for a later retro-commissioning study.

Related: Retro-Commissioning (RCx), Monitoring-Based Commissioning
Monitoring-Based Commissioning

An ongoing commissioning approach that uses permanent metering and building automation trend data to detect faults and verify persistence of savings. Analysis findings feed a prioritized list of operational corrections.

Related: Ongoing Commissioning, Retro-Commissioning (RCx)
Readiness Review

A pre-testing check confirming prerequisites such as completed checklists, calibration records, balanced systems, and available witnesses before functional testing proceeds. It prevents wasted effort from testing unprepared systems.

Related: Pre-Functional Checklist, Functional Performance Test
Controls Sequence of Operation

A written narrative describing how control devices and equipment respond to conditions and commands. Testers use it to design functional tests that confirm actual control behavior matches design intent.

Related: Functional Performance Test, Basis of Design
Trend Logging

Recording time-stamped sensor and equipment data over a period to verify performance and diagnose problems. Trends support functional testing, seasonal verification, and ongoing commissioning analysis.
