along the existing pipeline centerline from the start of pipe to end of pipe.

not following these specifications will be rejected and the Contractor shall be required to re-CCTV the work.
7.The documentation of the work shall consist of PACP CCTV Reports, PACP database, logs, electronic reports, etc.
