- Difficult retrofit and reinstatement
技术范围
Coordinate movement, services and barrier continuity before site conditions collide.
Joints and penetrations are different firestop conditions. Joints must accommodate defined movement; penetrations must account for the services, insulation, supports and opening geometry.
Complex conditions should be identified before closing works or procurement. Early mapping reduces emergency substitutions and inspection failures.
