How does one handle the following problem…Completed 2 FATs at 2 seperate suppliers successfully,(more of a component check as the 2 units are 12 000km apart) installed the equipment, (chiller unit and AHU.) Start up no problem but
1-AHU could not attain the design temperature and humidity levels. It was discovered that the calculated heat load for the area was insufficient so extra heating was installed.
2-Chiller unit kept shuting down. The supplier made 7 changes over a period of 3 weeks to their standard set-up (including change of hardware) to prevent this from occuring.
It now seems that the systems are “behaving”.
How would one handle these changes to the design specs. Drawings need to be altered, etc
As for the documentation part!!! the Commissioning/IQ/OQ protocols have already been approved for use as per the design specs and the commissioning docs are 3/4 executed when this was noted.
Change Control? Deviations? How? The design has been altered already!
HOpe someone can be of assistance.
