Notes & assumptions
- Default 14 × 12 m × G+3 = 168 m² per floor × 4 floors = 672 m² total built-up. Configurable 100-400 m² per floor across G+3 / G+4 / G+5. For larger apartment blocks or commercial complexes scale dimensions accordingly.
- **Column section guidelines** per IS 456 + IS 13920 (ductile detailing): G+3 → 400×400 mm (M25); G+4 → 450×450 mm (M30); G+5 → 500×500 mm (M30+). Smaller sections may be acceptable for short spans + light loading but rarely used in practice.
- **Steel ratio 170 kg/m³** is the appropriate average for G+3 to G+5 with seismic ductile detailing (IS 13920). Footings ~80 kg/m³, columns ~200-250 kg/m³, beams ~180-220 kg/m³, slabs ~80-100 kg/m³, stairs ~120 kg/m³.
- **Beam sections**: 230 × 500 mm for span 5-7 m; 230 × 600 mm for span 7-9 m. Stirrups 8 mm @ 100 c/c near supports (ductile zone) + 8 mm @ 150 c/c at midspan.
- **Lift shaft** is MANDATORY per NBC 2016 + accessibility guidelines for G+5 and above (6+ floors total). Strongly recommended for G+3 / G+4 for accessibility. 1.8 × 2.0 m clear shaft with 200 mm RCC walls all around. Lift car + machinery is separate procurement (₹8-15 lakh for 6-person passenger lift).
- **Cost target** for G+3 standard 14×12 m apartment (672 m² total): approximately **₹85 lakh - 1.10 crore** per CPWD DSR 2023 for basic civil + finishes (excluding GST + contractor profit). Market private rate: ₹1.20-1.50 crore turnkey (₹1,800-2,200 per sqft of total built-up).
- Excludes: lift car + machinery (₹8-15L for 6-person), electrical distribution + 100+ fittings (₹6-10L), plumbing + sanitary fittings + WC pans + wash basins + taps (₹8-12L for 6-8 bathrooms), kitchen platforms + dado + chimney (₹3-5L for 4 kitchens), modular wardrobes (₹2-4L), water tank + pump + plumbing fitouts (₹2-3L), DG-set backup (₹3-6L for 25-50 kVA), CCTV + intercom + access control (₹1-2L), compound wall + gate + landscaping (₹5-10L).
The **Multi-Storey RCC Frame (G+3 / G+4 / G+5)** is the workhorse of urban Indian residential + small-commercial construction — small apartment blocks, office buildings, mixed-use developments in tier-2/3 cities. Per **IS 456 + IS 1893 + IS 13920 (ductile detailing) + NBC 2016**, the standard construction uses isolated/combined RCC footings + 400-450 mm columns + 230×500 mm primary beams + 150 mm floor slabs + RCC dog-leg staircase + optional lift shaft + 230 mm brick infill walls + finishes. Higher steel ratio (~170 kg/m³ of total RCC) than low-rise buildings due to seismic ductility requirements. This Builder generates the complete BOQ from your dimensions + floor count; defaults to G+3 with 14 × 12 m footprint (168 m² per floor).
When G+3 / G+4 / G+5 — and what changes
**G+3 (4 floors total)** is the most common urban small-apartment / office configuration — 8-16 dwelling units, doesn't always need a lift (recommended), simpler structural design. Columns typically 400×400 mm M25. **G+4 (5 floors total)** crosses the lift-strongly-recommended + foundation-deepening threshold. Columns 450×450 mm M30. **G+5 (6 floors total)** is the lift-MANDATORY boundary per NBC + accessibility guidelines; also crosses the IS 13920 ductile detailing strictness threshold (now mandatory at every joint). Columns 500×500 mm M30. **Beyond G+5** (G+6 and above), structural design moves into 'mid-rise' territory: combined footings or raft, seismic isolation considerations, fire-fighting tank + dedicated stair pressurization. Use specialised structural-design + this template no longer fits — switch to a high-rise design course / consultant.
Per-sqft cost reality check
**CPWD DSR 2023 rates**: ₹1,250-1,650 per sqft of total built-up area for basic civil + finishes shell. **Market turnkey rates** for residential apartment buildings in 2026: ₹1,800-2,200 per sqft (tier-2 city, premium finishes) / ₹1,500-1,800 per sqft (tier-3 city, basic finishes) / ₹2,400-3,200 per sqft (tier-1 city, premium-to-luxury). The 30-50% gap vs DSR is the same as for G+1 — DSR excludes contractor profit, fittings, fixtures, market premium. The 672 m² (~7,200 sqft) default G+3 from this Builder at DSR comes to ~₹90 lakh civil shell; market turnkey for the same building is ₹1.25-1.55 crore.
Frequently asked questions
**~170 kg per m³ of total RCC** with seismic ductile detailing (IS 13920). For the default 14×12 m G+3 with ~120 m³ total RCC, that's ~20 tonnes of steel. Bar sizes typically: 20-25 mm in columns (main bars), 16-20 mm in beams (top + bottom), 12 mm in slab + beam stirrups + column ties (8 mm at midspan, 100 c/c stirrups near beam supports for ductile zone). Use **Fe500D per IS 1786** mandatory for seismic + corrosion durability.
