Why this method statement is used
This method statement is used to define and communicate the approved procedure for carrying out method statement: fireproofing inspection and itp for composite steel deck floor systems (soffit of trapezoidal galvanized deck) 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 | Pre-Inspection of Substrate | Inspect galvanized deck: verify fixings complete, surfaces free of oil, laitance, wetness, and debris. Conduct SSPC-SP 1 solvent clean where oil is present; assess dust per ISO 8502-3 if blasting/grinding occurred. | PFP Superintendent / QA-QC | Visual and touch check; solvent wipe test; moisture check |
| 2 | Surface Preparation for Galvanized Substrate | Prepare surface per ASTM D7803 and TDS: solvent clean; if required by manufacturer, apply compatible bonding agent/primer uniformly to all soffit surfaces of deck including ribs/flutes. Light abrasive sweep (SSPC-SP 7) only if permitted by deck and PFP manufacturers. | Applicator | Wet film thickness (WFT) spot checks for bonding agent; coverage verification |
| 3 | Environmental Controls | Measure ambient and substrate temperatures, RH, and dew point before and during application. Ensure ventilation; prevent condensation, water spray, or freezing conditions. | QA/QC | Meter readings every 2 hours and on change of shift/area |
| 4 | Masking and Protection | Protect adjacent elements (glazing, equipment, MEP) with poly sheeting and tape. Establish drip control at perimeter; isolate live electrics. | Applicator | Visual |
| 5 | Mixing and Pump Setup | Batch SFRM per TDS using clean water; maintain consistent water ratio and mixing time. Verify pump pressure and nozzle configuration suitable for deck ribs to achieve keying without rebound. | Applicator | Batch tickets and observation |
| 6 | Application—Scratch/Key Coat | Apply initial pass aimed into rib flutes at 30–60° nozzle angle to ensure keying; build thin scratch layer across webs and crests. Control rebound and shadowing by cross-pass technique. | Applicator | In-process visual; supervisor sign-off |
| 7 | Application—Build to Thickness | Build SFRM in multiple passes to achieve specified dry thickness over trapezoidal profile: measure at rib valleys, webs, and crests. Avoid heavy single-pass application leading to slumping or cracking. | Applicator | Spot depth checks during application |
| 8 | Detailing—Edges, Penetrations, and Interruptions | Treat edges, terminations at beams/walls, hangers, and openings. Install lath/mesh only where specified to maintain thickness. Provide neat arrises without feathering below minimum thickness. | Applicator | Visual check of details |
| 9 | Initial Cure and Protection | Maintain area free from impact, water spray, condensation, and freezing. Provide ventilation; prevent premature concealment. | Applicator / Site Team | Periodic check |
| 10 | Thickness Testing (ASTM E605) | After sufficient cure, perform dry thickness measurements across representative areas: for trapezoidal decks include readings at crests, webs, and valleys. Establish test lots per floor/zone. | QA/QC / Testing Agency | Randomized sampling |
| 11 | Density Testing (ASTM E605) | Obtain cores/scrapings per ASTM E605 to verify dry density where required by UL/EN design. | Testing Agency | Sampling witnessed by QA/QC |
| 12 | Cohesion/Adhesion Testing (ASTM E736) | Conduct pull-off tests at representative locations, including on galvanized deck ribs/valleys. Patch test locations after testing. | Testing Agency | Witness by QA/QC/Consultant |

- Records: Substrate acceptance forms, batch logs, WFT checks for adhesive, thickness/adhesion/density reports, environmental logs, NCRs/Corrective Actions, final acceptance certificate.
- Nonconformance: Stop work in affected area, raise NCR, investigate cause (surface contamination, curing/condensation, application technique), implement corrective action plan, re-test.
- Calibration: Verify calibration status of gauges/meters within 12 months; keep certificates on file.
- Traceability: Link batch numbers to areas applied; as-built plans showing tested locations.
- Interfaces: Establish hold point release prior to ceiling grid or MEP installation in each area; any damage by follow-on trades to be reported and repaired with re-inspection.
