Proposal

Introduction of additional cross-corridor fire-rated walls incorporating fire door sets to match the style of existing adjacent door sets, fire-rated ceiling with (hidden) bulkhead, which continues the plane of existing adjacent ceilings wherever new door set locations cause a step in the fire compartment line and localised investigatory works may be necessary to inspect and potentially remedy earlier construction methods, materials and fire-stopping details and install and integrate a new cooling system.
