Method Statement

Step-by-step procedure for a construction activity — safety, equipment, sequence, QC checkpoints.

Also calledmswork method
Definition

A Method Statement is a written description of the step-by-step procedure for executing a construction activity, listing the equipment, materials, manpower, safety precautions, sequencing, and quality checkpoints. Used in formal QA/QC systems and major construction projects to ensure consistent execution, training of workers, and provision of an audit trail. Per ISO 9001 + IS 14687 + project Quality Plans, Method Statements are mandatory for major activities and recommended for all non-trivial work.

A typical Method Statement includes: (1) Activity title — e.g., 'Concrete Placement for Floor 7 RCC Slab'; (2) Reference standards — IS codes, project specifications, drawings; (3) Manpower — number of workers, skill levels, supervision required; (4) Equipment — type, capacity, condition; (5) Materials — specifications, quantities, source; (6) Safety precautions — PPE, exclusion zones, fire prevention, emergency procedures; (7) Step-by-step sequence — pre-work checks, execution steps, post-work activities; (8) Quality checkpoints — inspection and testing requirements; (9) Hold and Witness Points — mandatory checkpoints requiring sign-off; (10) Acceptance criteria — measurable outcomes; (11) Approvals — signed by Method Statement preparer, structural engineer, contractor, third-party inspector.

Indian construction practice: (a) Government and PSU projects — Method Statements mandatory for major activities and submitted to client for approval before commencing. (b) Major commercial and infrastructure projects — typically required for concrete pours, structural steel erection, post-tensioning, special activities. (c) Private residential — rarely formalised; workers' skill and supervision substitute for written procedures. The Method Statement is most valuable for repetitive activities (every floor pour follows the same procedure) and for dangerous or skill-intensive activities (post-tensioning, pile installation, bored piling). The most-overlooked aspect: Method Statements should be reviewed and updated when conditions change (new equipment, worker turnover, season change, schedule pressure). Outdated Method Statements provide false comfort while reflecting old conditions.

Where used
  • Concrete placement — every pour, especially major rafts and transfer slabs
  • Pile installation — bored or driven, including specialised methods
  • Post-tensioning operations — strand placement, jacking, grouting
  • Structural steel erection — lifting, alignment, welding sequence
  • Pre-stressed concrete — sequence-critical operations
Acceptance / threshold
Per ISO 9001 + IS 14687 + project Quality Plan: signed approvals from preparer, structural engineer, contractor, third-party inspector. Submitted to client before commencing the activity. Reviewed and updated when conditions change.
Site example
Site reality: a Bengaluru post-tensioning project's Method Statement was approved at design stage (March 2025) but the contractor changed jacking equipment in October. The original Method Statement specified one jack model; the new model had different friction characteristics. The first 4 floors of post-tensioning had 8% lower effective pre-stress than design — discovered through routine elongation measurements. Re-approval and re-stressing required. ₹14 lakh remediation cost. Method Statements must be updated for equipment changes; outdated MS provides false assurance.
Frequently asked
What is a Method Statement?
A Method Statement is a written description of the step-by-step procedure for executing a construction activity, listing equipment, materials, manpower, safety, sequencing, and quality checkpoints. Used in formal QA/QC systems for ensuring consistent execution and providing audit trails. Mandatory in government and major commercial projects in India.
When is a Method Statement required?
Required for: (1) Concrete pours, especially major rafts, transfer slabs, mass concrete. (2) Pile installation — bored or driven. (3) Post-tensioning operations. (4) Structural steel erection. (5) Excavation and shoring. (6) Pre-stressed concrete. (7) Specialised techniques (jet grouting, diaphragm walls). (8) Repair work. Recommended for all non-trivial activities. In private residential, rarely formalised; in major projects, mandatory before activity commences.
Who prepares a Method Statement?
Typically prepared by the contractor's site engineer or QA/QC engineer, based on the project specification, drawings, and IS codes. Reviewed by the structural engineer and submitted to the client/third-party inspector for approval. Approval sequence: contractor → structural engineer → client → 3rd-party inspector. Once approved, the Method Statement governs site execution; deviations require re-submission and approval.
