Verified Quantities
| Category | Tag range | Qty | Source |
|---|
| Doors | D1 – D8B | 184 | Fusion + DXF ✓ |
| Glazed doors | GD1 – GD3 | 7 | Fusion + DXF ✓ |
| Windows | W6 – W15 | 25 | Fusion + DXF ✓ |
| Ventilators | V1 – V4 | 15 | Fusion + DXF ✓ |
| Total openings | — | 231 | SUM |
Quantity verdict: ACCEPTED — three independent methods (Fusion human take-off, DXF entity parse, rendered-plan visual) converge. Door tag-instances in DXF = 208 incl. schedule-table duplication; distinct openings = 184 (Fusion). Windows 25 / Vents 15 / Glazed 7 match DXF exactly.
Persona Review (BTI AI OS)
Two world-class personas delegated in parallel for zero-error QA:
Senior Quantity Surveyor / Costing — VERDICT: QUANTITY ACCURATE ✓
Arithmetic fully verified (184 + 7 + 25 + 15 = 231, all correct). Count-level accurate; corroborated by independent DXF parse. Missing for priced BOQ: leaf/slab sizes, frame material, glazing (incl. X-ray/RF shielding), fire rating (FD30/60/90 + smoke), ironmongery grade, supply+fix split, unit rates, wastage, prelims, VAT. Risks: 208→184 de-dup assumption, W1/W2/W3 exclusion, no compliance data, confirm AR-0210–0214 are latest revisions.
Lead Building Services Engineer (QA) — VERDICT: ACCEPTED-WITH-CONDITIONS
Counts independently corroborated by DXF parse — no counting error; defensible as a count. NOT a valid technical submittal until: fire/smoke + infection-control glazing confirmed, accessibility widths (900mm wheelchair / 1200mm stretcher) verified, W6–W15 operable-vs-fixed confirmed, and the ventilator anomaly resolved (15 louvres in clinical spaces contradict mechanical pressure-cascade ventilation — must confirm V1–V4 type/location; reject passive natural vents in clinical zones).
