When conducting a Fire Risk Assessment of External Wall (FRAEW) survey, a fire surveyor’s role is pivotal in assessing the safety of a building’s external wall systems. But what exactly does this process involve? Let’s break down the key steps and elements we focus on during an intrusive survey.
Pre-Survey Preparation
Before stepping on-site, preparation is essential:
1. Identifying Wall Types: We start by understanding the various wall types and determining strategic inspection locations.
2. Document Review: Reviewing building documentation, including drawings and specifications, provides context for the inspection.
On-Site Wall Assessment
Once on-site, we perform a thorough examination to uncover the entire wall build-up:
• Facade Materials: This includes examining components like vapour control layers (VCL), breather membranes, stud work, blockwork, structural elements, linings, insulation, outer wall leaf, cladding, and render.
• Critical Areas: Special attention is given to compartment floors, walls, window/door openings, balconies, service penetrations, and cavity edges.
Focus on Fire Safety Elements
The survey pays particular attention to passive fire protection measures:
• Cavity Barriers and Fire-Stopping: We check for the presence and condition of cavity barriers, fire breaks, and fire-stopping systems.
• Installation Accuracy: It’s crucial to verify these elements are installed correctly, following manufacturer guidelines.
Reporting the Findings
All findings are documented and compiled into a detailed report, which is shared with the Fire Engineer. This report supplements their assessment and ensures a comprehensive appraisal of the building’s external wall system.
