Quantities and Bill of Quantities (BOQ)
The Quantities workspace generates automated material take-offs and a customizable, rate-book-based Bill of Quantities (BOQ) directly from your building model.
Unlike manual spreadsheet estimations that take days and break whenever a wall moves, Jodu recalculates exact lengths, areas, volumes, and material breakdowns automatically on every model change.
What is in the Estimate & BOQ workspace?
The workspace is organized into four tabs:
- Overview: A dashboard summary showing priced vs unpriced items, total estimate, and readiness status at a glance.
- BOQ (Bill of Quantities): Itemized schedule of works with unit rates (material, labour, and total rates in ₹), quantity takeoffs, subtotals, and GST calculations.
- Material statement: Contractor-facing bulk procurement quantities:
- Cement: Total 50 kg bags required.
- Sand & Coarse Aggregate: Brass (100 cu ft) volume for masonry, plaster, and RCC.
- Reinforcement Steel: Total weight in kilograms (kg) and Metric Tonnes (MT).
- Brickwork & Blocks: Total number of standard modular bricks or AAC blocks.
- Measurements & assumptions: Traceable calculation breakdown and configurable costing assumptions (concrete mix ratios, steel density, wastage factors, GST rates, overhead & profit margins).
What building elements are measured?
| Construction Item | Unit of Measurement | Measurement source |
|---|---|---|
| Excavation & PCC | Cubic metres (m³) / Brass | Column footings and plinth trenches |
| RCC Structural Frame | Cubic metres (m³) / Brass | Footings, columns, plinth beams, floor beams, and slabs |
| Brick Masonry (230 mm) | Cubic metres (m³) / Square metres (m²) | External structural wall geometry minus openings |
| Partition Masonry (115 mm) | Square metres (m² / sq ft) | Internal room division walls |
| Internal Plaster (12 mm) | Square metres (m² / sq ft) | Internal wall and ceiling surface area |
| External Plaster (15-20 mm) | Square metres (m² / sq ft) | Exterior building shell surface area |
| Flooring & Tiling | Square metres (m² / sq ft) | Room carpet area assigned in Finishes |
| Skirting (100 mm) | Running metres (Rmt / Rft) | Room perimeter length minus door openings |
| Doors & Windows | Number of units (Nos) / Area (m²) | Count and area from Opening schedule |
| Painting & Primer | Square metres (m² / sq ft) | Wall and ceiling plaster coverage area |
How do I price and customize the BOQ?
- Open the Estimate workspace from the navigation bar.
- Switch to the BOQ tab.
- Review the matched rate-book items for each measured construction stage.
- To customize a rate, click Edit rate (or + Add rate for unpriced items) on any line item and enter your local contractor rate (split by material and labour, or combined total rate).
- Switch to the Measurements & assumptions tab to configure project-wide parameters:
- Concrete mix: M20 (1:1.5:3), M25 (1:1:2), etc.
- Wastage factors: E.g. 5% for bricks/tiles, 3% for concrete.
- Steel assumption: Rule-of-thumb ratios (e.g. 80 kg/m³ for slabs, 130 kg/m³ for beams, 160 kg/m³ for columns) if detailed rebar is unauthored.
- Taxes & Margins: Works contract GST (typically 18%), contractor overhead & profit (e.g. 10–15%).
- Click Save Assumptions — quantities are automatically recalculated. Use the Refresh button in the header to reload data after model changes.
What do the status indicators mean?
- "X of Y priced" (yellow badge): One or more rate-book rows have no rate entered. Jodu never treats a blank rate as zero-cost work to prevent underquoting.
- "X of Y priced" (green badge): All or most items have valid rates. Optional finish lines or minor fixtures may still be unpriced.
- "Ready to issue/share": All required items in the active building model have verified rates and all assumptions are saved.
Contractor procurement statement cheat-sheet
| Material | Conversion factor | Example for 100 m² (1076 sq ft) G+1 house |
|---|---|---|
| Cement | ~28.8 bags per m³ of M20 concrete; ~1.4 bags per m² of 230mm brickwork | ~450 to 550 bags total |
| Sand | ~0.45 m³ per m³ concrete; ~0.03 m³ per m² brickwork | ~12 to 16 Brass |
| Coarse Aggregate (Gitti) | ~0.85 m³ per m³ concrete | ~10 to 14 Brass |
| Steel (TMT Fe500) | ~2.5 to 3.5 kg per sq ft of built-up area | ~3.0 to 4.0 Metric Tonnes (MT) |
