As a practical civil engineer, I know that many projects — especially on weak or filled soil, waterlogged sites, or where the structural design calls for a rigid foundation — replace the traditional brick masonry foundation wall with a fully RCC wall on a strip footing. This gives better crack resistance, uniform load transfer, and durability compared to brick masonry below grade.
This RCC Foundation Cost Calculator helps you estimate the complete foundation cost where every foundation wall is cast in RCC instead of brick, resting on a strip footing 3 ft wide × 9 in thick. It covers excavation, PCC, RCC footing, RCC wall, plinth/tie beam, and labour.
Simply enter your total foundation wall length and the footing/wall dimensions, then click "Calculate Foundation Cost" to get a complete BOQ with quantities and costs.
Unlike a brick-masonry foundation (where quantities are usually scaled from covered area), an RCC wall + strip footing foundation follows the actual foundation layout, so this calculator works directly off your total foundation wall length (RFT) and the footing/wall cross-section you specify:
Concrete mix quantities use the standard 1.54 dry volume factor and a 1.25 Cft/bag cement conversion. All figures are based on common site practice in Pakistan and should be cross-checked against your structural drawings.
An RCC foundation wall resists differential settlement, moisture, and lateral earth pressure better than brick masonry, and is often preferred on weak, filled, or waterlogged soil, or where the structural engineer specifies a monolithic foundation.
A 3 ft wide × 9 in thick strip footing is a common size for low to medium-rise structures on reasonable soil bearing capacity. The exact width and thickness should always be confirmed by a structural engineer based on the soil bearing capacity and building loads.
Excavation depth is auto-calculated as Footing Thickness + RCC Wall Height — i.e., the trench is dug deep enough to cast the footing and then build the RCC wall up to plinth level within it.
This calculator assumes about 1.2% steel by concrete volume in the RCC wall (roughly 95 kg per m³), which is a common thumb-rule range for lightly to moderately reinforced foundation walls. Actual reinforcement must follow the structural drawing.
Yes — the footing width/thickness and RCC wall thickness/height fields are all editable. The defaults (3 ft × 9 in footing, 9 in × 3 ft wall) match the specification most commonly used, but you should adjust them to match your approved drawing.
These estimates are based on standard thumb rules and are accurate for preliminary budgeting and material procurement planning. For final procurement, always verify quantities with your structural engineer.
This RCC Foundation Cost Calculator is based on real-world construction data from Pakistan and follows common site practice for RCC wall foundations on strip footings. It is designed to help engineers, contractors, and homeowners quickly estimate foundation costs where brick masonry has been replaced with RCC.
It is particularly useful for:
