Why this method statement is used

This method statement is used to define and communicate the approved procedure for carrying out method statement: installation and maintenance of erosion and sediment control (esc) measures 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.

7	Dewatering through sediment control	If excavation water present, pump to sediment bag or settling tank; discharge to vegetated area/trap. Use flow control to avoid scour. Add flocculant only with approved plan and jar tests. Monitor turbidity at discharge using calibrated meter.

Environmental Officer/Foreman	Ongoing; records kept
9	Environmental monitoring and reporting	Undertake visual turbidity checks during rain events. Where required, collect upstream/downstream or inflow/outflow samples for NTU/TSS; calibrate meters daily when in use. Submit weekly/monthly summary with exceedances and corrective actions.	Environmental Technician/Manager	Witness: first sampling event; Audits by Engineer
10	Demobilization and reinstatement	Once areas are stabilized (e.g., ≥70% vegetative cover or permanent surfacing) [Verify], remove temporary ESC progressively from upstream to downstream. Dispose of captured sediment to approved location; re-grade and seed/disturbance repaired. Final inspection and sign-off.	Foreman/Environmental Officer	Hold: final area inspection before removal
