The ITP and commissioning procedures found in

Appendix A of this manual provide the detailed instructions for commissioning the IP Turbine-

Generator #4 Switchgear and associated equipment.

4.2 CONSTRUCTION TEST PHASE

During the construction test phase, the Contractor will perform the necessary inspections and tests to ensure that completed installations are acceptable and in accordance with the latest engineering and design information. The results of construction testing will be documented by the Contractor.

4.3 PRE-OPERATIONAL TEST PHASE

The Contractor will perform all pre-operational testing. The Commissioning Director and staff will witness the checkout and testing during this phase to ensure that tests are conducted in accordance with approved procedures prior to commencing the operational testing phase.
