The construction programme runs from site possession on Monday 22 June 2026 to Practical Completion on Friday 25 September 2026. The project is structured as three overlapping phases with sectional completion — L6 (reception floor) completes first, then L5, then L4. This allows the tenant's London-to-Manchester migration to begin in parallel with ongoing works on lower floors.
Strip-out (phased L6→L5→L4), partition first-fix, M&E first-fix. Concurrent working once L6 strip-out complete. Long-lead deliveries arrive: joinery Wk 8, switchgear Wk 9, raised floor Wk 7.
Ceilings, joinery install, M&E second-fix, lighting, floor finishes, paint, AV install. Sectional completions: L6 Wk 11, L5 Wk 13, L4 Wk 14. Commissioning runs concurrent with finishes.
M&E commissioning (witnessed), BMS integration with landlord, AV configuration, snagging, O&M documentation, tenant walkdown, handover. PC certificate issued 25 Sep.

Sectional completion LDs: £8,500 per working day per section. Tenant move-in scheduled Mon 12 October 2026 (2-week buffer post-PC for cleaning, FF&E install and IT migration).
Floors 1–3 remain occupied by existing tenants throughout the project. All logistics must work within the constraints of a live, occupied commercial building with a single goods lift and shared loading bay. These constraints are contractual — breach of noise or access protocols triggers the landlord's step-in clause.
Commissioning is phased to align with sectional completion. L6 commissions first (Wk 10), L5 next (Wk 12), L4 last (Wk 13–14). Each floor follows a four-step sequence: M&E testing, BMS point-to-point, snagging walkdown, handover sign-off.

These risks were identified during the Pre-Con Pack workflow and are now transferred to the delivery team with mitigations in place. The full risk register (11 items) is maintained in the Stage 05 (Green Light™) internal workflow document.
| Risk | Description | Impact | Mitigation | Owner |
|---|---|---|---|---|
| R-01 | Joinery long-lead (10–12 wk) delays programme | High | Order placed 13 Jun. Factory pre-fit visit Wk 6. Weekly progress photo from Holroyd. Buffer: 1 week built into programme. | Pre-Con / Procurement |
| R-03 | Landlord CHW capacity — late confirmation delays M&E first-fix | Medium | Letter of comfort received 18 Apr. Follow-up confirmation due Wk 8. Fallback: temporary cooling if delayed beyond Wk 12. | Site Manager / QS |
| R-05 | Goods lift availability — shared access limits material delivery throughput | Medium | Advance booking protocol (48hr). Bulk deliveries scheduled for early morning (07:30–09:00) before existing tenants' peak. Joinery delivery via external hoist if lift unavailable. | Site Manager |
| R-07 | Noise complaints from L1–L3 tenants trigger landlord step-in | Medium | Noise monitoring installed. Restricted hours enforced (10:00–16:00). 48hr advance notification protocol. Building Manager relationship managed weekly. | Site Manager |
| R-09 | Raised access floor — replacement rate exceeds 15% estimate | Medium | Survey complete (14 May) — 13% measured, 2% contingency. If exceeded: Threshold Floors NW confirmed 4-day lead on additional panels. Budget: provisional allowance held. | QS |
| R-11 | AV integration with tenant London HQ — network config delays | Medium | N. Bramwell (Wexley IT) confirmed Zoom Rooms platform 27 May. Network switching tenant-direct (excluded from scope). Pre-config session booked Wk 16. | Visualis AV / Wexley IT |
The Pre-Con Pack outputs don't end at mobilisation. They become the baseline data for three downstream Built AI workflow packs. This section maps what goes where — so the delivery team knows which documents are live inputs to other workflows, not just archived records.
