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.
Method statement content
Scope
Overview
This method statement defines the procedures, responsibilities, HSE controls, QA/QC, and Inspection & Test Plan (ITP) for commissioning of building standpipe systems (wet and dry). Activities include pre-functional checks, flushing, hydrostatic testing, pneumatic supervision testing (where applicable), flow and pressure testing at roof hydrants and hose connection valves, PRV setting/verification, fire brigade inlet (FDC) testing using a pumper or test pump, documentation, and handover.
Systems Covered
- Class I, II, and III standpipe systems (automatic wet, automatic dry, semiautomatic dry, manual wet, and manual dry) [Verify per project design].
- Associated appurtenances: roof hydrants/manifolds, hose connection valves (1-1/2 in. and 2-1/2 in.), pressure-reducing valves (PRVs), isolation valves, check valves, gauges, drains, test headers, and fire department connections (FDCs).
- Interfaces with fire pumps (if present), water supply mains, and fire alarm/supervisory systems.
Objectives
- Demonstrate system integrity (no leakage), operational readiness, and performance compliance.
- Verify minimum residual pressure and required flow at hydraulically remote outlets and roof hydrants.
- Verify FDC delivers required flows/pressures to remote outlets.
Exclusions
- Permanent fire pump acceptance testing beyond integration steps (separate method if required).
- Permanent building water mains disinfection.
- Structural works or modifications.
Key Acceptance Targets [Verify per project specifications and AHJ]
- Hydrostatic test: 200 psi (13.8 bar) or 50 psi (3.4 bar) above maximum system working pressure, whichever is greater, for 2 hours, no leakage (per NFPA 14).
- Flow testing: Achieve required standpipe total flow and residual pressure at topmost outlets: typically 100 psi (6.9 bar) for Class I/III, 65 psi (4.5 bar) for Class II. Total required flow typically 500–1000 gpm depending on number of standpipes/high-rise classification.
- PRVs: Outlet pressure at rated test flow per design, stable within ±5 psi [Verify per design and NFPA 14].
- Dry standpipe supervision (if used): Stable air/nitrogen supervision pressure over test duration within acceptable drop limits [Verify per project HSE plan and NFPA guidance].
