Model integrity & coverage
The model is machine-checked against its own invariants before anything is rendered. Diagnostics are shown, never hidden.
CONSISTENT — all scope, area, unit, BOQ, rate, cost, financing, revenue, profit, schedule and traceability invariants hold.

Forward derivations (project scope → engineering inputs)
- Identity from scope: 30 storeys × 600 m² = 18000 m² above-grade GFA; 3 basements × 600 m² = 1800 m² basement GFA; total GFA 19800 m² over 33 levels.
- Unit program from scope: 182 units, 11250 m² sellable, 2376 m² service/core, 4374 m² common (GFA − sellable − parking − service/core).
- Building footprint 600 m² at a 2.5:1 aspect ratio → perimeter 108 m (used for facade and hydrant layout, never the land perimeter).
- Cut = footprint 600 m² × basements 3 × 4 m per basement × working-space/slope factor 3 = 21600 m³. Fill = cut ÷ 18 reused around footings = 1200 m³ (demonstration derivation).
- Columns = 24 per storey (core + perimeter) × 30 storeys = 720 (demonstration derivation).
- Slabs = 31 (30 storeys + roof) of 30 m × 20 m footprint (600 m² divided at 30 m length, demonstration derivation).
- Rebar bar schedule = slab area 18600 m² ÷ 1.0333 m² per bar ≈ 18000 bars (demonstration schedule — NOT a structural design).
- Partitions = 1200 m run (40 m per storey × 30, demonstration) with 540 m² openings (18 m² per storey, demonstration derivation).
- Structural frame = 4 beam lines/floor × 30 m × 33 levels (0.4 × 0.65 m) + core/shear walls 90 m² × 0.3 m × 33 levels + 2 stair flights/level (3.2 m rise @ 0.28 m going, 1.4 m wide). Screening-level, not a design.
- Basement works over 3 levels: base slab 600 m² × 0.6 m, retaining walls 108 m × 3.2 m × 0.35 m, columns at 1 per 60 m², grade beams 0.35 m/m², ramp 120 m², tanking + 1 sump per level. Derived from the same footprint and perimeter as the building.
- Lifts sized on 182 units × 2.4 persons × 1.1 population factor, 5-minute handling interval, 13-person cars, 110 s cycle; shafts over 99 m.
- Facade = perimeter 108 m × 30 storeys, 60% glazed / 40% opaque panel; parapet 1.2 m; roof 100% of the 600 m² plate. Facade is geometric, not a share of sellable area.
- mep electrical = TOTAL GFA 19800 m² (basements included) × 50 W/m² = 990.0 kW connected; diversity 60% → 594.0 kVA max demand (demonstration).
- Transformer sized on the 594.0 kVA computed max demand + 15% allowance, rounded up to a standard rating; generator on 35% critical load; luminaires at 14 m² each and emergency luminaires at 22 m² each over 19800 m².
- mep plumbing = 182 units × 4 FU/unit = 728 FU; cold water 15 m/floor, hot 10 m/floor, drainage 12 m/floor (demonstration).
- Plumbing demand = 182 units × 2.4 persons × 180 L/person/day → storage sized on a 12-hour drawdown (min 120 m³); booster set on 12 L/s at 58 m head; stormwater from roof 600 m² + hardstanding at 180 L/s/ha.
- mep mechanical = TOTAL GFA 19800 m² × 3 m × 2 ACH = 118,800 m³/h air; cooling 1980 kW (demonstration).
- fire safety = TOTAL GFA 19800 m² (basements included) ÷ 12 m²/head = 1650 sprinkler heads; riser 96 m; hydrants every 30 m along the 108 m building perimeter.
- Fire water & egress = occupant load at 12.5 m²/person over 19800 m²; design flow 0.15 L/min/m² over 60 min, tank floored at 150 m³; 2 pump zones (duty + standby each); 2 escape stairs serving 33 levels with rated doors to every served floor.
- Finishes = 11250 m² sellable (from the unit program) × 3 for wall surface = 33750 m² internal wall area; plaster 15 mm = 506.3 m³; tiles 30%, flooring 11250 m² (demonstration).
- Site infra = site 2400 m² (from the scope) − footprint 600 m² − landscaping 360 m² = 1440 m² paving; fencing ~196 m (demonstration).
- testing = 7 systems × 50 pts = 350 test points; 7 systems × 5 days = 35 commissioning days (demonstration).
