Firestop services for vertical shafts, risers and service zones where rated continuity and access conditions can be challenging.
Scope and Field Conditions
Shaft & Riser Firestopping should be approached as a system condition rather than a generic material application. The wall or floor assembly, penetrant, opening geometry, movement, insulation and surrounding construction all influence how the condition should be coordinated.
Typical Scope
- Riser floor penetrations
- Shaft wall interfaces
- Dense service coordination
- Access planning
Our Project Workflow
We organize the work around pre-installation condition review, field sequencing, controlled installation, punch-list response and closeout documentation. This makes it easier for general contractors and trade partners to understand what has been completed and what still needs attention.
Documentation Matters
Where project requirements call for system references, location tracking, photographs or closeout packages, those records should be captured while the work is accessible. The NYC Firestop CMS includes dedicated content and lead workflows that support this documentation-first positioning.
