Is a group of activities that commence during the construction phase of a project .These activities
prepare and enable the facility to move to the main commissioning phase.
The range of ASE services that may apply include:

Can be seen as the stage the various systems and equipment are put into initial operation.Utility
systems, instrument air, cooling water and general-purpose water are made live and the core process
systems are first made operational.It should be noted that Pre-Commissioning and commissioning can
be seen by some clients as one and the same thing
