Perform Building Commissioning Inspection using eAuditor

Building Commissioning is a systematic and structured quality assurance process used during the planning, design, construction, and operation phases of a building project to ensure that all building systems are designed, installed, tested, and verified to perform as intended. The goal is to deliver a facility that operates efficiently, meets the owner’s project requirements, and provides a safe, comfortable, and sustainable environment for occupants.

Performing Building Commissioning Inspection using eAuditor ensures a thorough evaluation of building systems’ installation, operation, and integration while maintaining safety, functionality, and compliance with standards.

This document is a comprehensive, step-by-step eAuditor-ready guide for planning, executing, recording, and reporting Building Commissioning activities. It follows an owner-focused approach and maps Building Commissioning tasks to clear inspection items, test procedures, and digital workflows in eAuditor. Use this as a template to copy into eAuditor, tailor to project-specific OPRs, and convert into recurring inspections.

1. Scope & Objectives

1.1 Scope

Building commissioning encompasses all phases of a construction project where building systems are installed, tested, verified, and handed over. The scope includes:

• New construction and major renovations where commissioning is mandated by codes or required by owners.
• Core systems subject to commissioning, including:
  • Heating, Ventilation, and Air Conditioning (HVAC): AHUs, FCUs, chillers, boilers, pumps, VFDs.
  • Building Automation and BMS systems.
  • Electrical distribution: switchgear, UPS, standby generators, ATS systems.
  • Lighting and lighting control systems.
  • Plumbing, domestic hot water, and sanitary systems.
  • Fire and life safety systems, including alarms, sprinklers, and smoke management.
  • Vertical transportation systems, such as elevators and escalators.
  • Building envelope: roofing, fenestration, insulation.
  • Renewable energy systems (solar PV, geothermal, cogeneration, energy recovery).
  • Specialized systems (medical gases, laboratory exhaust, data centers).

1.2 Objectives

Commissioning ensures that the finished facility aligns with the Owner’s Project Requirements (OPR). Objectives include:

• Ensuring compliance with the OPR and Basis of Design (BOD).
• Verifying that equipment and systems are installed properly.
• Validating operational performance under both normal and emergency conditions.
• Documenting deficiencies, implementing corrective actions, and verifying rectifications.
• Delivering comprehensive training, manuals, and ongoing support for operators.

2. Owner’s Project Requirements (OPR)

The OPR serves as the backbone for commissioning. Using eAuditor, create a dedicated OPR checklist that contains:

• Energy targets: kWh/m²/year, demand load targets.
• Indoor environmental quality standards: temperature, humidity, CO₂ ppm thresholds.
• Redundancy expectations: e.g., N+1 chillers, dual electrical feeds.
• Operational conditions: building hours, occupancy profiles, load variations.
• Comfort requirements: noise levels, air quality parameters.
• Safety requirements: code compliance, fire protection standards.

Each inspection in eAuditor should trace back to a related OPR entry. For example:

• AHU-03 supply air test linked directly to OPR: Supply air between 20–24°C.
