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 metal parapet coping caps and flashings 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 Sequence
| Step | Activity | Description | Responsibility | Inspection / Hold Point |
|---|---|---|---|---|
| 1 | Set-out and Verification | Verify parapet dimensions, straightness, and slope. Mark coping centerline and cleat lines. Confirm coping width covers parapet plus required drips; typical overhang 25–40 mm each side [Verify]. | Site Engineer / Surveyor | Dimensional survey |
| 2 | Substrate Preparation | Clean parapet top and faces; repair voids; ensure dry. Install isolation layer over masonry where specified to avoid galvanic action with metal. | Foreman | Visual |
| 3 | Underlayment Installation | Apply self-adhered underlayment over parapet top and down both faces ≥150 mm; roll firmly to bond; lap per manufacturer (typically 75–100 mm). Tie into roof membrane or leave shingle-lap for later tie-in. | Roofer/Sheet Metal Installer | Adhesion check; lap inspection |
| 4 | Fabrication Check | Confirm coping, cleats, splice plates, and corners match approved shop drawings. Dry-fit one bay if necessary. | QA/QC | Visual, measurement |
| 5 | Install Continuous Cleats | Fix continuous cleats to both parapet faces per profile. Fastener spacing: 200–300 mm o/c [Verify]; 50–75 mm from ends. Embedment: wood ≥30 mm; steel full thread; concrete/masonry per anchor approval. Stagger fasteners vertically. Maintain straightness ±3 mm per 3 m. Do not distort cleats. | Installers | Fastener spacing/edge distance check; torque spot checks |
| 6 | Corners and Terminations | Install pre-formed internal/external corners and end caps. Provide end dams ≥25 mm at terminations. Seal concealed laps with butyl tape; solder/weld only where specified and permitted. | Installers | Fit-up and sealing check |
| 7 | Internal Splice Plates at Joints | Place splice plate centered under each joint with butyl tape both sides of joint. Fix splice plate to one coping section only; maintain designed slip on adjacent section. Do not fasten through coping top. | Installers | Joint preparation check |
| 8 | Coping Section Placement | Place coping over cleats; engage hems uniformly along length. Ensure even overhang/reveal both sides. Protect finishes during handling. | Installers | Alignment check |
| 9 | Thermal Expansion Gaps | Set expansion gap between coping sections based on α·L·ΔT. Typical joint gap 6–12 mm for 3–4 m long aluminum sections; 4–8 mm for steel/stainless [Verify]. Do not seal the gap rigidly; allow concealed movement over splice. | Site Engineer/Installers | Measure gap at each joint |
| 10 | Drive Cleat Jointing | Fit drive cleat across joint to lock both coping hems without penetrating top. Tap in progressively to achieve snug fit; avoid paint damage. Apply discrete sealant only where specified and not restricting movement. | Installers | Engagement check |
| 11 | Counter-Flashings/Tie-ins | Install counter-flashings/reglets to tie coping to roof membrane upstand per roofing detail. Sealant per ASTM C920 where exposed. | Installers/Roofer | Compatibility and lap check |
| 12 | Final Fix, Protection, and Cleaning | Remove protective films; clean surfaces with approved cleaner; remove swarf. Install temporary protection if other trades ongoing. Record as-builts. | Installers/QA | Final visual inspection |
Health, Safety, and Environment – Safety Controls
Task-Specific Hazards and Controls
1) Hazard: Working at height at roof edge

- Required PPE: Full body harness with double lanyard SRL where applicable, helmet with chinstrap, non-slip safety footwear.
- Collective preventive measure: Guardrails and toeboards prioritized over personal fall arrest.
- Inspection/permit/supervision: Work at Height Permit; daily inspection of harness and MEWP; supervisor to monitor wind limits. [Verify per project HSE plan and local regulations].
2) Hazard: Manual handling of long, sharp-edged coping sections in windy conditions
- Likely consequence: Musculoskeletal strain, lacerations, dropped objects.
- Engineering/procedural control: Team lifts with coordinated commands; use panel carriers/suction cups; avoid handling above 10 m/s wind; store flat on dunnage; use tag lines when lifting.
