Why this method statement is used

This method statement is used to define and communicate the approved procedure for carrying out method statement: placement and compaction of concrete in deep vertical elements (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.

Tolerances (typical) [Verify per project]

  • Plumb: ±6 mm per 3 m height, not to exceed ±12 mm total per element.
  • Dimensions: ±10 mm (columns/walls typical).
  • Cover: As per drawings; tolerance −6/+10 mm (ACI 117 typical).
  • Surface quality: No honeycombing; bugholes within class finish limits; edges and arrises sound.

Frequently asked questions

Limit free-fall to 1.5 m without a trunk/hose. For deeper drops, use an elephant trunk or pump hose so the outlet stays within 300–600 mm of the rising surface [Verify per project specs].

Use smaller heads (25–32 mm), insert vertically, space at about 1.5× the radius of influence, penetrate 75–100 mm into the previous lift, and vibrate 5–15 seconds until air ceases.

Adopt the formwork designer’s limit. Typical values are 1.0–1.5 m/h depending on mix temperature and setting time [Verify per ACI 347R and supplier guidance].

Test slump and temperature on every truck; air content initially and then every 25–50 m³ or on changes; compressive strength sets per 50 m³ or per pour/day minimum [Verify].

When the concrete has reached adequate strength to support itself and imposed loads; timing per specification and ambient conditions [Verify].
