Systematic inspection, testing and commissioning of MEP systems prior to handover.
Work inspection requests and site inspections are coordinated so installed MEP works can be reviewed before concealment, testing or handover. Records are kept against the approved drawings and project inspection process.
Installed MEP systems are tested and commissioned in a planned sequence. The objective is to demonstrate that systems operate as installed, documented and ready for client use.
Applicable piping systems are hydrostatically tested in accordance with the project specification, with test sections, pressures and durations agreed before the test starts.
Pressure testing is used to verify the integrity of applicable MEP pipework before insulation, backfilling or concealment. Leaks are identified and rectified before the system proceeds.
Systems are flushed to remove debris and prepare pipework for operation, following the specified flushing method and cleanliness requirements.
Chilled water systems are tested for tightness, flow and operating conditions as required by the project, before they are placed into regular service.
Pumps are checked for rotation, operation, pressure and control interface so they can be accepted as part of the commissioned system.
Air and water systems are tested and balanced to the approved design values where specified, with adjustments recorded as part of commissioning documentation.
