Why this method statement is used

This method statement is used to define and communicate the approved procedure for carrying out method statement: final integrated systems testing (ist) demonstration for project completion 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.

Frequently asked questions

To demonstrate end-to-end integration of life-safety and building services functions in accordance with the approved Cause & Effect Matrix and test scripts, achieving acceptance by the Engineer/Client/AHJ.

All life-safety interfaces must be 100% tested. For repetitive non-critical integrations, representative sampling (e.g., 25–50%) may be accepted if allowed by project specifications and Engineer approval.

Failures are logged with unique IDs and categorized A/B/C. Category A must be rectified immediately. Retesting is requested via formal RTT, with evidence recorded and cross-referenced.

Typical targets are alarm annunciation within 10 s, lift recall within 60 s, and generator load restoration within 10 s for Type 10 systems. Always verify per project specifications and codes.

Commissioning team, discipline leads, OEM vendors, QA/QC, HSE, and witnesses from the Engineer/Client. AHJ attendance is required where mandated.
