Every step sequenced, and gated on inspection
The works above Level 3 on an 18,400 square foot Cat-A fit-out: high-level containment, cable, pipework, ceiling grid, commissioning and handover, in seven inspection-gated steps over six weeks. Each operation is signed off before the next begins, and the method statement is issued only alongside the signed risk assessment.

Cat-A fit-out, Levels 4 to 6
18,400 square feet over three floors. Mechanical risers terminate at Level 3, so this method statement covers the works above that point: high-level containment, cable pull and termination, chilled-water and condensate pipework, ceiling grid, commissioning and handover. The programme runs six weeks, with mobilisation in week 1, M&E first fix across weeks 2 to 4, ceiling grid in weeks 4 to 5, and snagging in week 6.
The site supervisor holds the inspection register. Each operation is signed off before the next begins, and BuiltAI cross-references the register weekly against the QA checklist. Any substitution of resource or method is raised as a RAMS revision through the job intake, not decided on site.
Seven steps, inspection-gated
Each step lists its acceptance criteria. The hold before cable pull and the pressure test on the pipework are the two points where work stops until an inspection is signed.
| Step | Method and acceptance criteria |
|---|---|
| 01 Mobilisation and welfare set-up | Welfare in place, 110V supply tested, exclusion zones at lift lobbies, induction logged |
| 02 High-level cable tray containment | Perforated tray to layout, hangers at 1.5m centres, bonding tested, held for inspection before cable pull |
| 03 Cable pull and termination | Armoured for distribution, LSF for branch circuits, continuity, insulation and earth-loop tested to BS 7671 18th Edition |
| 04 Chilled-water and condensate pipework | Compression jointed to BS EN 1057, pressure test at 1.5 times working pressure for 60 minutes, condensate fall verified at 1 in 100 |
| 05 Ceiling grid installation | Exposed grid, level checked by laser to plus or minus 2mm, penetrations within 5mm, tiles loose-laid for snagging |
| 06 Commissioning and pre-handover snagging | Commissioning to BSRIA BG 49, chilled-water flush and flow balance, client snag list raised |
| 07 Handover and demobilisation | Final clean, O&M manuals issued, as-builts re-issued, welfare cleared, practical completion signed |
Personnel, plant and materials
The resource ceiling for this method statement. Daily allocation is tracked by the site supervisor against the weekly programme.
Personnel
1 supervisor (NEBOSH), 6 electricians (JIB Gold), 3 M&E fitters, 4 ceilings operatives, 2 general labourers.
Plant
2 mobile elevated work platforms (4m), cable-pulling winch (110V), hydrostatic test pump, multifunction tester, 2 rotating laser levels.
Materials
Perforated steel tray, armoured and LSF cable per schedule, copper pipework 22, 35 and 42mm, exposed ceiling grid, mineral-fibre tiles.
This method statement is issued only alongside the signed risk assessment for the site. Work does not proceed on the strength of the method statement alone.
Inspection and hold points
Each operation carries an inspection and an acceptance criterion, signed by the site supervisor before the next begins. Two are hard hold points where work stops until the inspection is signed.
| Operation | Inspection and acceptance | Point |
|---|---|---|
| Containment | Tray to layout, hangers at 1.5m centres, bonding continuity proven | Hold before cable pull |
| Cable installation | Continuity, insulation and earth-loop tested to BS 7671 18th Edition | Sign before energise |
| Pipework | Pressure test at 1.5 times working pressure held for 60 minutes | Hold, witnessed |
| Condensate | Fall verified at 1 in 100 along each run | Sign before close-in |
| Ceiling grid | Level checked by laser to plus or minus 2mm, penetrations within 5mm | Sign before tiles |
| Commissioning | Chilled-water flush and flow balance to BSRIA BG 49 | Client witness |
| Handover | O&M manuals, as-builts and test records issued and accepted | Practical completion |
The site supervisor holds the inspection register and signs each operation off before the next begins. BuiltAI cross-references the register weekly against the QA checklist, and any failed inspection stops that operation until it is corrected and re-signed.
