Below is a ready-to-paste set of review comments you can give to the planner /
scheduler.
Each line tells them exactly what to change in the master programme so that Level-5
IST and Punch-List Administration now satisfy every item in the AWS pre-energisation
checklist you showed earlier.
A. General Review Comment (put this in the transmittal e-mail)
“Level-5 IST tasks are generally captured, but sequencing and gating do not yet align
with the AWS Pre-Energisation Checklist Rev-1.
Please action the detailed remarks in the attached mark-up so that all checklist
prerequisites are logically tied to the ‘Ready for Energisation’ milestone and no
safety-critical task remains after the system is live.”
B. Detailed Mark-Ups (line-by-line)

D. Logic Links to Add
1. Oil BDV → HYPACT Soak (F/S)
2. HYPACT Soak → Ready for Energisation (F/S)
3. Ready for Energisation → Switching of 33 kV Incomer (F/S)
4. Switching 33 kV Incomer → Overall Commissioning (F/S)
5. Overall Commissioning (start) → O&M Training (F/S)
6. Post-Energisation Punch Close → As-Built Submission (F/S)
E. Duration / Resource Reality Checks
GIS + Tx Soak: minimum 24 h continuous monitoring – give it 2 calendar days so
the schedule reflects a night shift.
TNB End-to-End: utility witness often slips; insert 1 day free float ahead of
Ready for Energisation.
Training: 15 days appears long; confirm with the client – may be 5 days
classroom + 5 days on-site is enough.

How to Deliver These Comments
1. Export the Primavera bar chart to PDF, turn on Activity ID + Activity Name +
Start/Finish columns.
2. Redline exactly the changes above (use call-out bubbles; reference the
comment numbers).
3. Attach this table as “Comment Register – Rev 0”.
4. Ask the planner for a re-run of the schedule logic and an updated critical-path
report within 48 h.
That gives the scheduler clear, unambiguous instructions and ties every amendment
back to the AWS checklist, so nothing gets lost in version churn.
