What are some common BCxP pitfalls that can hinder project success?

• A. Inadequate OPR/BOD, late Cx planning, insufficient testing, lack of independence for CxA, improper documentation.
• B. Overemphasis on energy savings beyond safety.
• C. Too early Cx planning.
• D. Too much testing.

Answer: (A)

The main idea here is that a successful BCxP relies on clear performance criteria, early and thorough planning, objective verification by an independent reviewer, and solid documentation. When these elements are missing or weak, commissioning can miss the mark and the project can fail to meet owner expectations.

Without an adequate Owner’s Project Requirements and Basis of Design, there’s no firm baseline for what the systems must achieve or how they should behave. The commissioning process uses those benchmarks to verify performance, so if they’re incomplete or not approved, you end up with misaligned goals, scope gaps, and difficulty proving that the final building actually meets the owner's needs.

Planning for commissioning late creates a squeeze: there’s not enough time to craft a robust test plan, coordinate sequence-dependent checks, allocate the right resources, and iterate based on findings. This often leads to rushed tests, incomplete defect identification, and testing that doesn’t fully validate operations before occupancy.

Insufficient testing means issues can remain hidden until after the system is in use. You need thorough, representative tests to confirm that equipment operates as intended, that control strategies deliver the required comfort and performance, and that energy targets are achievable in real-world conditions. Skimping on testing undermines confidence in the building’s performance.

A lack of independence for the Commissioning Authority undermines objectivity. When the CxA is too closely tied to the project team, there can be pressure to downplay problems or overlook deficiencies. Independence helps ensure discoveries are documented honestly and that all issues are resolved before occupancy.

Improper documentation leaves a trail of unanswered questions. Clear test procedures, results, issues, and resolutions must be recorded so operations staff can maintain and troubleshoot systems, and so future projects can learn from what was done. Poor documentation breaks the continuity between design, commissioning, and facility operations.

These interconnected pitfalls—weak performance baselines, late planning, insufficient testing, lack of independent verification, and poor documentation—consistently hinder BCxP success. While other scenarios (like planning too early or excessive testing) can matter in some contexts, they don’t embody the same broad impact on project outcomes as this combination.
