Tools › User guides › Boundary Wall Estimator
The Boundary Wall Estimator works out the materials and cost of a brick compound wall with RCC columns and plinth beam the way it is done on Indian sites: excavation, PCC, footings, columns, beams, brickwork, plaster, cement, sand, aggregate and a steel schedule.

| Field | What to enter | Typical value | Tip |
|---|---|---|---|
| Plot length / Plot width | Outer size of the plot along the wall line. | e.g. 30 × 40 ft | Perimeter = 2 × (L + B). |
| Wall height above ground | Height of the wall above ground level. | 5 – 7 ft | |
| Gate / gap width (deducted) | Total width of gates and openings. | 10 – 12 ft for a car gate | Deducted from the perimeter. |
| Spacing between columns | Centre-to-centre spacing of RCC columns. | 8 – 10 ft (2.5 – 3 m) | Number of columns = perimeter ÷ spacing, rounded up. |
| Open run, not a closed loop | Tick if the wall does not close on itself (e.g. one side only). | Unticked | Adds one end column. |
| Field | What to enter | Typical value | Tip |
|---|---|---|---|
| Excavation depth below GL | Depth of the foundation pit. | 3 – 4 ft | |
| Footing size L × B | Plan size of each column footing. | 3 × 3 to 4 × 4 ft | |
| Footing thickness | In the section unit. | 9 – 12 in | |
| PCC thickness | Lean concrete under the footing. | 4 – 6 in | |
| PCC mix | 1:3:6, 1:4:8 or 1:2:4. | 1:4:8 |
| Field | What to enter | Typical value | Tip |
|---|---|---|---|
| Column size b × D | RCC column size. | 9 × 9 or 10 × 10 in | |
| Plinth beam b × D | Beam size. | 9 × 12 in | |
| Number of beam levels | Plinth beam only = 1; with a top tie beam = 2. | 1 – 2 | |
| Wall thickness | Brick wall thickness. | 5 in (half brick) or 10 in | |
| Concrete grade | M15 – M35. | M20 | |
| Deduct columns from brickwork | Removes the column volume from the wall. | Ticked |
| Field | What to enter | Typical value | Tip |
|---|---|---|---|
| Bricks per cum of masonry | Number of bricks in 1 m³ with joints. | 450 – 500 (modular) | |
| Mortar as % of masonry volume | Wet mortar volume. | 25 – 30 % | |
| Masonry mortar ratio | Cement : sand. | 1:6 | |
| Plaster thickness (mm) | 12 – 20 | ||
| Plaster faces | 1 or 2. | 2 | |
| Plaster mortar ratio | 1:4 – 1:6 | ||
| Dry volume factor for mortar | Wet to dry volume. | 1.27 – 1.33 | |
| Wastage on materials (%) | Added to all materials. | 2 – 5 |

| Footing bars: dia & spacing | Mesh in each footing. | 10 mm @ 150 | |
| Column main bars: nos & dia | 4 – 12 mm | ||
| Column ties: dia & spacing | 8 mm @ 150 | ||
| Beam through bars: top & bottom nos, dia | Continuous bars. | 2 + 2, 12 mm | |
| Extra bars: nos & dia, run over % of length | Extra bars at supports or mid-span. | 2 – 12 mm over 30 % | |
| Beam ties: dia & spacing | 8 mm @ 150 | ||
| Cover: footing / column / beam | 50 / 40 / 25 mm | ||
| Tie hook allowance | Hook length per tie. | 20 × dia | |
| Column bar bend into footing | L-bend length. | 200 mm | |

The right side shows Quantities (excavation, PCC, RCC by member, brickwork, plaster), Materials (cement bags separately for concrete, mortar and plaster, then totalled; sand; aggregate; bricks), the Steel schedule (bar-wise length and weight) and an Abstract. One cement bag is taken as 50 kg = 0.0347 m³.
The tool divides the wall length (perimeter minus the gate) by the column spacing and rounds up; an open run adds one more column. Keep the spacing around 8–10 ft.
Yes. Change Length input to metre and Section input to mm in the units bar.
It gives the material quantities and abstract; multiply by your local rates, or use RCC Estimator Pro for a full building.
