Why this method statement is used
This method statement is used to define and communicate the approved procedure for carrying out method statement: high‑voltage cable drum delivery, unloading, and yard storage on site. It ensures the work is planned in advance, the correct resources and controls are in place, and all personnel understand responsibilities, sequence, quality requirements, and safety controls before work begins. It aligns site execution with the documented scope and acceptance expectations.
Who uses this method statement
This method statement is used by contractors, site supervisors, project engineers, QA/QC engineers, HSE officers, consultants, and client representatives. It serves as a shared reference for planning, execution, supervision, inspection, and approval of the activity on site.
When it is prepared and submitted
The method statement is prepared before the work activity starts and submitted as part of the pre-construction documentation package for review and approval.
Who reviews or approves it
The method statement is usually submitted to the client representative, consultant, resident engineer, or project management consultant for review and approval before the work commences.
Important approval note
This method statement is an AI-assisted editable starting point, not a pre-approved document. Before use on any project, all content must be reviewed and approved by the relevant parties (superintendent, principal contractor, or client representative) in accordance with your contract and project quality plan.
For example: if your specification requires a departure from a referenced standard, that departure must be documented and approved separately — this method statement will not capture that automatically. Always verify against your applicable drawings, specifications, and regulatory requirements.

Frequently asked questions
No. Lifting via flanges or direct sling wrap around the drum risks structural damage. Use a rated heavy axle lifting shaft through the barrel with a spreader beam per the Lift Plan.
Quarantine the drum, record an NCR, and reseal within 2 hours using approved caps and mastic. Add desiccant and consult the manufacturer before further handling.
Only for short distances on level ground and strictly in the direction of the arrow, with banksman control, two tag lines, and wedges. Do not roll on slopes or uneven ground.
Follow crane OEM limits. As a benchmark, suspend standard lifts at sustained wind above about 9 m/s or gusts above 13 m/s. Verify per Lift Plan and OEM guidance.
Inspect weekly for general condition and monthly for detailed checks. For storage exceeding 3 months, rotate the drum about 90° monthly in the arrow direction [Verify].
