Fire & life safety and circulation
How everyone gets out safely, and how guests, staff and vehicles move without crossing.
Fire & life safety
SBC 801 and NFPA 101, fully sprinklered. Escape routes lead to protected fire stairs, final exits at ground level and the assembly points.

| FLS-01 | Basement | 8 | 94.9 m | 122 m (car park) | ✓ OK |
| FLS-02 | Ground floor & site | 11 | 63.9 m | 76 m | ✓ OK |
| FLS-03 | Mezzanine | 7 | 36.1 m | 76 m | ✓ OK |
| FLS-04 | First floor | 8 | 91.4 m | 76 m | Review – longer than the limit; resolved in the R17 FLS set |

Circulation & function
Separate entries for guests, banquet guests, VIPs and service; two guest lift lobbies and separate service lifts.
- Guests: porte-cochère → lobby → reception → lifts A or B → rooms and amenities.
- Banquet guests: own pedestrian entry → pre-function → halls, without crossing the hotel lobby.
- VIP: west entry and garage → VIP lobby → dedicated VIP lift.
- Service: north service entry and loading → back-of-house corridor → service lifts → housekeeping on every floor.
- Vehicles: drop-off loop at the fountain; basement ramp down (north lane) and up (south lane).

Lifts – traffic analysis
CIBSE Guide D round-trip-time method with hotel criteria (interval 30–50 s, 5-star ≤ 40 s; 10–15 % of population in 5 minutes).
| Guest lifts | 6 (2 groups × 3 – Lobby A and Lobby B) |
| Car | 1,275 kg · 17 persons · 2.0 m/s |
| Floors served | B, G, M, 1F, 2F–6F, Roof |
| Round trip time | 117.8 s |
| Interval per group | 39.3 s ✓ (5-star ≤ 40 s) |
| Handling capacity (5 min) | 37 % of population ✓ (≥ 12 %) |
| With only 2 lifts per group | 58.9 s ✗ – so 3 per lobby are kept |
| Keys per guest lift | 38 |
| Service lifts | 3 ✓ (minimum 2 for 228 keys) |
| Fire-fighting lift | 1 per fire-fighting shaft (SBC 801) – service car, protected lobby |
Car size to be confirmed by the lift supplier; one stretcher car (1.1 × 2.1 m) per core.
