Why this method statement is used
This method statement is used to define and communicate the approved procedure for carrying out method statement: qa/qc hold points for facade alignment and tolerance verification 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.

Safety Controls
Task-Specific Hazards and Controls
1) Hazard: Work at height from MEWP/scaffold near facade edges

- Collective preventive measure: Guardrails/toeboards on platforms; fall arrest systems; barricades and signage
- Inspection/permit/supervision: PTW for work at height; daily MEWP/scaffold inspection log; competent operator and supervisor; weather check for wind limits [Verify per project HSE plan and local regulations]
2) Hazard: Falling objects during measurement/adjustment
- Likely consequence: Struck-by injury to persons below; facade/glass damage
- Engineering/procedural control: Tool lanyards; secure small parts in pouches; exclusion zone beneath work area; debris nets where required
- Required PPE: Hard hat, safety footwear, eye protection
- Collective preventive measure: Physical barriers and spotters controlling access below
- Inspection/permit/supervision: Daily inspection of lanyards/attachments; supervisor to enforce exclusion zones
3) Hazard: Glass/metal sharp edges during joint gauge use
- Likely consequence: Lacerations to hands/forearms
- Engineering/procedural control: Use cut-resistant gloves; avoid sliding hands along edges; maintain protective films where possible
- Required PPE: Cut-resistant gloves (EN 388 level per risk), long sleeves, safety glasses
- Collective preventive measure: Briefing on safe handling; dedicated handling points
- Inspection/permit/supervision: Supervisor checks PPE compliance; first-aid kit available nearby
4) Hazard: Laser exposure from TS/laser level
- Likely consequence: Eye irritation/injury
- Engineering/procedural control: Use Class 2/3R lasers only; avoid beam at eye level; post laser-in-use signs
- Required PPE: Eye protection as needed
- Collective preventive measure: Controlled survey line-of-sight; restrict bystanders
- Inspection/permit/supervision: Verify laser class; operator training; equipment calibration records
5) Hazard: Pinch/crush during panel adjustment
- Likely consequence: Hand/finger injuries; musculoskeletal strain
- Engineering/procedural control: Use designed adjustment points and tools; no hands in pinch zones; team communication and spotter
- Required PPE: Impact/cut-resistant gloves; safety boots
- Collective preventive measure: Method briefing; lock-out of lifting equipment not in use
- Inspection/permit/supervision: Supervisor oversight during adjustments; stop-work authority if unsafe
6) Hazard: Weather (high winds, heat)
- Likely consequence: Loss of control of access equipment; measurement errors; heat stress
- Engineering/procedural control: Suspend works above equipment wind limits; schedule checks in stable conditions; hydration and rest breaks
- Required PPE: Weather-appropriate PPE; sunscreen where applicable
- Collective preventive measure: Shade/water stations
- Inspection/permit/supervision: Monitor wind speed/temperature; supervisor to pause works if limits exceeded
7) Hazard: Manual handling of straightedges and equipment at heights

- Engineering/procedural control: Use tether points for long straightedges; team lifts; store equipment securely on platform
- Required PPE: Gloves, safety footwear
- Collective preventive measure: Equipment racks on platforms
- Inspection/permit/supervision: Pre-use checks; supervisor verification
Note: Apply further controls required by the project HSE plan and local regulations.
Environmental Controls
- Protect facade surfaces from staining or adhesive residue; use non-staining tapes and remove promptly after checks.
- Prevent debris from falling to public/landscaped areas; use debris nets/exclusion zones and clean-down at end of shift.
- Manage MEWP emissions/noise per site rules; avoid idling; schedule noisy activities within permitted hours [Verify per local regulations].
- Collect and segregate packaging waste from targets/spacers; dispose via designated recycling streams.
- Do not discharge wash water or cleaning solvents to drains; if cleaning is required for accurate measurement, use approved products and capture waste [Verify per project EMP].
- Avoid measurements during direct facade heating that may cause thermal bow; record ambient temperature and wind to contextualize as-built data.
- Protect biodiversity and adjacent properties by preventing object drop and dust; maintain housekeeping standards.
QA/QC
Measurement Methods
- Position: Total Station set-out and independent check-back per ISO 4463-1. Use resection/backsight checks; apply least-squares adjustment where appropriate.
- Level: Digital level double-run; close levelling loops; record misclosures.
- Plumb: Digital inclinometer on mullions; cross-check with plumb laser over representative height.
- Levelness: Laser/digital level on transoms.
- Joint width: Calipers or joint gauges at top/mid/bottom of each joint; record min/avg/max.
- Planarity: 2 m straightedge with feeler gauges across panel seams and within panel fields.
Sampling and Frequency [Verify per project]
