Why this method statement is used
This method statement is used to define and communicate the approved procedure for carrying out method statement: fixing and tying of vertical reinforcement cages for structural columns and shear walls 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.

Health, Safety, and Environment (HSE) – Task-Specific Safety Controls
Key Hazards, Consequences, Controls, PPE, and Requirements
1) Hazard: Struck-by or crush during lifting/erection of cages
- Likely consequence: Serious injury/fatality from dropped/ swinging load
- Engineering/procedural control: Engineered lift plan; certified rigging; taglines; exclusion zone; weather limits (suspend lifts above safe wind threshold [Verify per site policy, typically 9–12 m/s])
- Required PPE: Hard hat with chin strap, gloves, safety boots, high-vis, eye protection
- Collective preventive measure: Barriers and banksman control; radio communication; no access under suspended load
- Inspection/permit/supervision: Pre-lift inspection checklist; Lifting Supervisor in control; valid PTW for lifting
2) Hazard: Cage instability/topple before concreting

- Control: Temporary bracing designed/checked by Site Engineer; base clamps; guying; routine re-check after wind or impact
- PPE: As above
- Collective measure: Physical bracing, secured anchors, exclusion zone maintained
- Requirement: Daily brace inspection and after adverse weather; recorded on brace checklist
3) Hazard: Falls from height while tying upper lifts
- Likely consequence: Major injury/fatality
- Control: Provide working platforms/scaffold with guardrails; fall arrest only if collective protection not feasible; maintain three points of contact on ladders (work from ladder prohibited for tying beyond brief access [Verify])
- PPE: Full-body harness with double lanyard if fall arrest used
- Collective measure: Mobile towers/podiums, edge protection
- Requirement: Scaffolds tagged after inspection; PTW for work at height
4) Hazard: Rebar impalement and lacerations

Environmental Controls
- Steel and tie-wire waste: Segregate and send to licensed recycler; collect tie-wire offcuts in bins at workface.
- Oils/grease from equipment: Store spill kits at lifting and assembly zones; drip trays under hydraulic tools; immediate spill containment and report.
- Noise: Schedule high-noise cutting/bending to daytime; use acoustic barriers near sensitive receptors; monitor if required by permit.
- Dust/particulates: Minimize dry cutting; wet wipe bars if dusty; maintain housekeeping; no abrasive blasting without permit.
- Visual and site tidiness: Stack bars on dunnage; maintain clear walkways; remove protruding offcuts promptly.
- Waterways/drain protection: Keep work away from drains; fit silt socks; no washout into stormwater.
- Material provenance: Retain mill certs to demonstrate responsible sourcing if required (e.g., BES 6001 equivalent) [Verify].
- End-of-shift: Remove loose wires, empty bins, secure cages against wind, and close exclusion zones.
Quality Assurance and Quality Control
