41Actions raised

Key finding: Evidence is strong for structure, sprinklers and smoke control. Fire stopping, cavity barriers and fire doors have gaps that can still be closed while areas are accessible. Waiting until commissioning would risk opening up finished work and delaying the application.

2. Evidence status by element

Element	Evidence required	Available	Status
Structural frame	Pour records, cube results, engineer sign-off	All floors	Green
Compartmentation walls	ITPs, pre-close inspections, photos per wall	L1–L14 only	Amber
Fire stopping (penetrations)	Per-penetration record, product data, installer certs	~55% of penetrations	Red
Cavity barriers (façade)	Location plan, install photos before closing, inspection	No photos L10–L13	Red
Façade system	Fixing inspections, product certs, test evidence	Complete to L17	Amber
Fire doorsets	Certification, install inspection, gap checks	Install checks 40%	Red
Sprinklers	Install, pressure tests, commissioning plan	Tests to L18	Green
Smoke control	Install records, commissioning plan	Complete to date	Green
Dry riser	Install, pressure test	Test L1–L19	Green
Fire alarm & detection	Install, cause & effect, commissioning	Install 80%	Amber
Firefighting lift	Install, test plan	In progress	Amber
As-built information (golden thread)	Linked drawings, change log, O&M	Structure agreed, partly populated	Amber

3. Priority actions

#	Action	Owner	Due	Priority
1	Survey and record all open penetrations L10–L19 before ceiling close-up; one record per penetration in Field View	Fire stopping sub + QA	27 Mar	High
2	Cavity barriers L10–L13: intrusive sample inspection (min. 10 locations) to confirm installation; record findings	Façade sub + QA	13 Mar	High
3	Fire doorsets: complete install inspections incl. gaps, hinges, seals; link certification to door schedule	Joinery sub + QA	10 Apr	High
4	Compartmentation L15–L19: pre-close inspections at hold points before boarding	Drylining sub + QA	Ongoing	Medium
5	Golden thread: agree folder structure and naming; link each record to location and drawing revision	Principal Contractor	20 Mar	Medium
6	Fire alarm cause & effect sign-off with commissioning programme	M&E contractor	24 Apr	Medium

4. Sample verification on site

Floor	Items checked	Matched records	Comment
Level 3	24	23	1 penetration sealed but no record → recorded
Level 9	24	21	3 penetrations with no record; 1 incorrect product (NCR raised)
Level 16	18	12	Records not yet uploaded by subcontractor

5. Recommendation

Set a 12-week evidence recovery plan with weekly reporting against the actions above, and make closed-up areas conditional on a completed Field View record. Re-run this analysis at Rev B (target 22 May 2026) to confirm readiness for the Gateway 3 application.
