Questions Asked in Site Inspection and Commissioning Interview
Q 1. Explain the process of pre-commissioning.
Pre-commissioning is the process of verifying that all the individual components of a building system are installed and function correctly before they are integrated into the overall system. Think of it as a series of individual health checks before the system’s ‘big race’. It’s crucial because it helps identify and rectify issues early, preventing costly rework and delays later in the commissioning process.
- Component Testing: This involves testing each component—pumps, valves, sensors, etc.—individually to ensure they meet the manufacturer’s specifications. For instance, we might check a pump’s pressure and flow rate against its data sheet.
- Equipment Inspection: This phase focuses on verifying the correct installation of the equipment, checking for any damage during transport or storage, and ensuring that all necessary connections are made properly. This might include visually inspecting ductwork for leaks or verifying the proper grounding of electrical equipment.
- Documentation Review: This involves meticulously reviewing the manufacturer’s instructions, specifications, and as-built drawings to confirm that the installation conforms to the design intent. A discrepancy between the design and the installed system would be identified here.
- System Walkthroughs: This involves a physical walk-through of the system, identifying any potential conflicts or issues before full integration. This could reveal a clash between pipework and structural elements, for example.
By addressing problems during pre-commissioning, you avoid cascading issues during the later stages, saving both time and money. A simple example is finding a faulty sensor during pre-commissioning; correcting this then is far less disruptive than discovering it during the system’s functional testing.
Q 2. Describe your experience with commissioning HVAC systems.
