EXPP: PROTECTED STRUCTURE: 1. Upgrades to existing internal doors. 28no. existing timber panelled doors will receive upgrades to permit their certification as 30 minute fire-resisting doors with smoke-seals. The nature and location of these doors, and the method statement for upgrade are detailed. 2. Replacement of modern internal doors. 18no. existing, late twentieth century, flush door-sets are to be replaced with new certified fire-resisting solid-core door-sets. 3. Existing walls along escape routes will have fire stopping installed where services penetrate them. Fitting may require limited taking down of ceilings. 4. At third-floor level a section of existing internal walling will be removed to permit the formation of a corridor to the external escape stair. 5. The third-floor access to the external escape stair is currently provided through a painted timber, one-over-one sliding-sash window. This has been deemed inadequate as a storey exit, and it is proposed to replace the upper and lower sashes with an outward opening casement. The proposed casement will preserve the proportions and profiles of the existing sash to minimise the visual impact of this change, and the casement will be fitted to the existing sash-box. 6. Some late twentieth century stud partition walls at ground floor will be over-boarded with fire-rated plasterboard to improve their compartment rating. 7. A late twentieth century glazed screen at first floor will be replaced with a fire-rated, plasterboard stud wall.
