2. Issue Identification and Tracking

• Capture problems in an issues log
• Follow through until resolution
• Ensure each item is closed by the responsible party

3. Safety and Load Protection

• Maintain safety standards and never allow tests to endanger staff, equipment, or live load

4. Objective Reporting

• Report findings factually and transparently to owners, contractors, and vendors
  Stay impartial — advocate only for the facility’s operational reliability.

What a Cx Engineer Is Not Responsible For

1. Correcting Issues

• Cx engineers do not repair, rewire, or adjust systems
• Responsibility for correcting deficiencies lies with vendors, contractors, or installers

2. Altering Design

• If a test exposes a design flaw, the solution belongs to the EOR

3. Operating Equipment

• Cx engineers do not operate or take ownership of systems
• They may direct or witness vendors performing actions during tests, but they do not manipulate equipment themselves

4. Owner’s Business Decisions

• Budget, schedule, or contractual impacts remain outside the Cx engineer’s role
• Their authority is technical, not financial

Industry Standards Backing

This philosophy is not just opinion - it is reinforced by multiple professional associations and standards bodies:

• ASHRAE - Guideline 0 and Standard 202 define commissioning as a quality-focused process of evaluation and documentation to verify that systems meet the Owner’s Project Requirements (OPRs). The Cx Authority plans, tests, and reports - but does not correct or redesign.
• BCxA (Building Commissioning Association) - Positions the Cx professional as the owner’s advocate, responsible for impartial verification and documentation. Their code of ethics emphasizes independence and neutrality.
• ACG (AABC Commissioning Group) - In their Guidelines for Total Building Commissioning, ACG defines the Cx role as ensuring systems are installed and function per OPRs, with corrections belonging to contractors and vendors.
• NEBB (National Environmental Balancing Bureau) - Through certification programs, NEBB reinforces that commissioning professionals test and validate systems, but installation and correction remain the contractor’s responsibility.
• USGBC / LEED – Commissioning is required for certification, and the CxA must be independent of design and construction teams. The CxA verifies and documents, while designers and contractors correct deficiencies.
• Uptime Institute (Data center-specific) - Their Tier Certification of Constructed Facility (TCCF) process depends on commissioning to prove redundancy and resiliency. The Cx team’s role is to verify Tier compliance - not to alter equipment or correct vendor work.
