This relocation shall be submitted to the engineer for approval and shall be coordinate with plant operations to ensure they are not impacted in any way. This work could include wet tapping of existing lines to relocate them to allow them to remain in service. The program shall include hand digging of electrical conduit and chemical piping and other small piping and machine excavation for larger pipes with hand digging once exposed. The test pit program shall also locate any valving to be replaced. The program shall be conducted at the initiation of the project to allow the Contractor to properly plan work while maintaining plant facilities and operations.
