BCxA Certified Commissioning Professional (CCP) cheat sheet

Commissioning (Cx) is a quality-focused process applying documented methods to verify that all building systems perform interactively according to the Owner's Project Requirements (OPR) and the design intent.

The Cx process spans five phases: pre-design/planning, design, construction, occupancy/handover, and ongoing operation; each phase produces defined deliverables and gate reviews.

A Commissioning Plan (Cx Plan) defines scope, systems to be commissioned, roles and responsibilities, schedule, budget, documentation, and acceptance criteria; it is a living document updated each phase.

The Commissioning Team typically comprises the Cx Authority (CxA), Owner, design team, contractor(s), and specialty vendors; the CxA's independence from the design and construction contracts preserves objectivity.

Systems typically commissioned: HVAC, plumbing, electrical, fire protection/life safety, building envelope (if in scope), controls/BAS, elevators, and renewable energy systems.

Total Building Commissioning integrates envelope, structural, mechanical, electrical, plumbing, fire protection, and interior systems into one coordinated process rather than isolated system checks.

Key performance metric: Cx cost typically ranges 0.5% to 2% of total construction cost depending on scope and building complexity; benefits include reduced change orders and improved energy performance.

The Cx schedule must link to the master construction schedule; functional testing should be scheduled before substantial completion to allow correction of deficiencies.

A commissioning program for an Owner establishes standard templates, requirements, roles, and QA procedures applied across multiple projects.

The OPR is a written document that details the functional requirements of a project and the expectations of how it will be used and operated, including program, schedule, budget, environmental, and operational criteria.

OPR content typically includes: project goals, measurable performance criteria, cost and schedule constraints, occupancy and use, environmental and sustainability goals, IEQ requirements, energy efficiency targets, and O&M expectations.

The Basis of Design (BOD) is the designer's written explanation of the assumptions, calculations, and decisions that support the design; it must be traceable to the OPR.

Design review compares BOD against OPR to confirm alignment; any OPR element not addressed in the BOD is flagged as a gap for resolution.

The OPR is owned by the Owner (often authored with the CxA's assistance) and updated as project goals evolve; BOD is owned by the design team.

Measurable OPR criteria (e.g., temperature setpoints, ventilation rates, lighting levels, energy use intensity) become the acceptance benchmarks for functional performance testing.

OPR should address future flexibility, expandability, and operational staffing assumptions because these drive system selection and controls strategy.

A design review report documents discrepancies, omissions, and conflicts between OPR and BOD and is issued to the design team for resolution before construction documents are finalized.

OPR/BOD updates must be version-controlled; late changes affecting design or construction require formal change management and Cx Plan updates.

Pre-construction Cx activities include design review, development of the Cx Plan, Cx specification review, contractor procurement input, and pre-construction/pre-bid meetings.

Design reviews typically occur at schematic design, design development, and construction documents stages, with a final review before bid/award.

Design review checks: OPR-to-BOD traceability, system sizing and redundancy, controls sequences, accessibility for maintenance, energy code compliance, and constructability.

The CxA reviews construction documents for commissioning-related content: testing requirements, sensor/access provisions, TAB scope, controls points, and O&M deliverables.

A pre-bid or pre-construction meeting communicates Cx scope, roles, schedule, and documentation requirements to bidders and contractors to reduce later disputes.

The CxA prepares a preliminary Cx schedule and a systems list (commissioned vs. non-commissioned) during pre-construction to define scope boundaries.

Design review comments should be tracked in a log with responsible party, due date, and resolution status; unresolved items escalate to the Owner.

The CxA verifies that the Cx requirements are incorporated into the project specifications before bid issue; missing requirements are added via addendum.

The Cx specification (typically Division 01, Section 01 91 00 or equivalent) defines Cx scope, team roles, contractor responsibilities, submittal requirements, testing procedures, and acceptance criteria.

The Cx specification must require contractor participation in pre-functional checklists, functional performance tests, TAB, controls point-to-point verification, and O&M/training deliverables.

Contract documents should clearly allocate responsibility for deficiency correction, retesting costs, and schedule impacts to avoid disputes.

The CxA is typically procured directly by the Owner (not through the design or construction contract) to preserve independence and objectivity.

The Cx specification requires a Cx kickoff meeting, submittal review of Cx-related submittals (e.g., controls, TAB, test plans), and contractor-prepared test procedures.

Procurement should verify that bidders acknowledge Cx requirements; failure to include Cx scope in bids often results in change orders later.

The specification defines acceptance criteria and documentation deliverables: pre-functional checklists, functional test reports, issues log, systems manual, and training records.

Warranty and O&M requirements (e.g., 11-month warranty review) should be specified in the contract to support ongoing commissioning.

Construction-phase Cx includes submittal review, pre-functional checklists (PFCs), installation verification, TAB oversight, controls point-to-point verification, and startup documentation.

Pre-functional checklists confirm that equipment is installed per manufacturer requirements and design before functional testing begins; contractor completes and CxA verifies.

Installation verification includes checking clearances, access, labeling, pipe/duct insulation, seismic restraint, electrical connections, and controls wiring.

TAB (Testing, Adjusting, Balancing) reports verify design air and water flows; the CxA reviews TAB for completeness and consistency with design values.

Controls point-to-point verification confirms each sensor, actuator, and output is correctly wired and mapped to the BAS before sequence testing.

Startup reports from manufacturers document equipment condition at energization; the CxA reviews for anomalies before functional testing.

The CxA maintains a construction-phase issues log with severity, responsible party, and resolution status; unresolved issues block functional testing.

Seasonal testing constraints (e.g., heating in summer) require deferred testing provisions documented in the Cx Plan and specifications.

Functional Performance Testing (FPT) verifies that systems and components perform interactively according to the OPR, BOD, and contract documents under simulated and actual conditions.

FPT procedures specify: system/equipment tested, prerequisites, instrumentation, test steps, expected results, acceptance criteria, and documentation.

Test methods include: normal operation, part-load, full-load, failure/mode simulation, alarm verification, and sequence-of-operation verification against the controls narrative.

Acceptance criteria must be measurable and traceable to the OPR/BOD (e.g., setpoint ± tolerance, flow within ±10% of design, response time).

The CxA witnesses and documents tests; the contractor operates equipment and corrects deficiencies; the Owner's representative observes critical tests.

Test results are documented in FPT reports with pass/fail status, observed vs. expected values, and deficiency references; retesting is required after corrections.

Seasonal/deferred testing is scheduled when weather-dependent conditions cannot be achieved during initial testing; results are appended to the Cx record.

Sample-based testing may be used for repetitive equipment (e.g., VAV boxes) with a statistically defensible sampling rate approved by the Owner.

The issues log (deficiency log) tracks each issue with ID, description, location, responsible party, severity, due date, status, and resolution evidence.

Deficiencies are categorized by severity (critical, major, minor) and by type (design, installation, controls, TAB, documentation) to route correction correctly.

Critical deficiencies affecting life safety, code compliance, or major function must be resolved before substantial completion; minor items may be tracked to closeout.

Retesting is required after correction of any deficiency that failed an FPT; retest results are recorded and linked to the original issue ID.

Acceptance is documented via a Certificate of Acceptance or substantial completion letter confirming that Cx requirements are met or that remaining items are tracked.

The CxA recommends acceptance to the Owner based on completed FPTs, resolved critical issues, and delivered documentation; the Owner makes the final acceptance decision.

Closeout documentation includes the final issues log, FPT reports, PFCs, TAB reports, and a summary of deferred/seasonal tests.

A punch list (separate from the Cx issues log) addresses cosmetic or minor construction items; the Cx log focuses on performance and functional compliance.

The Systems Manual compiles OPR, BOD, as-built drawings, equipment schedules, controls sequences, TAB reports, FPT results, warranties, and O&M data for Owner operations.

Systems Manual content should be organized by system and include narrative descriptions of operation, control sequences, setpoints, and troubleshooting guidance.

Training requirements are specified in the contract: audience, topics, duration, format (classroom/hands-on), and documentation (agendas, attendance, recordings).

Training should cover normal operation, emergency procedures, controls/BAS use, maintenance tasks, and warranty procedures; it is verified by the CxA.

Handover includes a Cx final report summarizing process, results, outstanding items, and recommendations for ongoing commissioning.

The CxA verifies that as-built documents, O&M manuals, spare parts, and warranties are delivered and consistent with installed equipment.

An Owner orientation session familiarizes facility staff with the Systems Manual and the ongoing Cx plan.

Handover documentation supports future retro-commissioning by providing baseline performance data and design intent records.

Ongoing Commissioning (OCx) is a continuous process integrated into facility operations to maintain performance and identify degradation over time.

Retro-Commissioning (RCx) applies the Cx process to existing buildings not previously commissioned, focusing on low-cost operational improvements.

RCx phases: planning/scoping, investigation (data collection, trend analysis, walkthrough), implementation of findings, and ongoing monitoring/handover.

Key RCx metrics: Energy Use Intensity (EUI), energy cost savings, simple payback, and persistence of savings; typical savings range 5% to 15% of total energy use.

Monitoring-Based Commissioning (MBCx) uses continuous BAS trend data and analytics to detect faults and prioritize corrective actions.

The Cx Plan for OCx defines monitoring scope, frequency, KPIs, reporting, and responsibility for corrective action.

RCx investigation includes reviewing OPR (or developing a current-facility OPR), trend data, TAB records, and interviewing operators.

Findings are prioritized by savings potential and implementation cost; low-cost/no-cost measures are typically implemented first.

Persistence of savings requires periodic re-verification and updating of setpoints, schedules, and sequences as occupancy changes.
