Why this method statement is used

This method statement is used to define and communicate the approved procedure for carrying out method statement – building management system (bms) testing & commissioning 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.

Method statement content

Scope

Overview

This method statement covers the complete testing and commissioning (T&C) of the Building Management System (BMS), including:

Pre-commissioning installation readiness (control panels, field devices, cabling, labeling, earthing, network infrastructure).
Controller power-up, firmware/configuration, addressing, database loading, time sync and backups.
100% point-to-point I/O testing and calibration of sensors/actuators.
Graphics verification, naming conventions, alarm classification/priorities, trend logs (intervals and retention), and schedules (occupancy/holiday).
Functional Performance Testing (FPT) of sequences of operation for HVAC plant (AHUs, FAHUs, VAVs/FCUs, Chiller/Boiler plants, pumps, cooling towers) and control loops.
Third-party interfaces (e.g., BACnet/Modbus devices, fire alarm shutdowns, power meters, elevators status, lighting via gateways) and interlocks.
Witness testing with Consultant/Employer’s Representative, snag rectification, re-testing, and progressive acceptance.
Final documentation: as-built controls drawings, point lists, database/graphics source, commissioning records, O&M manuals, training, and handover.

Exclusions

TAB (Testing, Adjusting, Balancing) of air/water systems (performed by TAB contractor) but coordinated for BMS testing.
Life-safety system commissioning other than BMS interfaces (e.g., fire alarm cause/effect calibration performed by fire system contractor).

Locations
