Why this method statement is used
This method statement is used to define and communicate the approved procedure for carrying out method statement: installation of final sanitary ware fixtures (wcs, wash basins, bidets, showers, urinals) 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 defines the detailed procedure for the final installation of sanitary ware fixtures including WCs (floor- and wall-hung), wash basins (wall-hung, pedestal, countertop), bidets, showers (mixers, heads/handsets, trays or floor gullies), and urinals (bowl and trough types). It covers:
- Brackets, carriers, and anchoring to substrates
- Connection of water supplies via isolation valves and flexible braided connectors
- Installation of traps (P-trap/Bottle trap), wastes, and pan connectors
- Silicone perimeter jointing and sealing at sanitary interfaces
- Functional testing (leak, flow, flush, trap seal, operation) and commissioning checks
- Protection of installed fixtures until handover and damage prevention measures
Exclusions
- Rough-in of concealed pipework and frames already installed and pressure-tested
- Waterproofing works beyond local sealing at fixture interfaces
- Electrical connections to sensor valves/flush valves (covered by electrical MS)
Objectives
- Achieve compliant, watertight, dimensionally accurate, hygienic installations without damage to finished surfaces
- Meet architectural intent, accessibility requirements, and performance standards [Verify per project specifications]
