How the formula works
Volume = Length × Width × Depth | Total Cost = Concrete + Labor + Excavation + Reinforcement
- Foundation Volume = Length × Width × Depth (cubic feet)
- Concrete Cost = Volume × Concrete Cost per Cu Ft
- Labor Cost = Volume × Labor Cost per Cu Ft
- Excavation Cost = Volume × Excavation Cost per Cu Ft
- Reinforcement Cost = Concrete Cost × (Rebar Factor / 100)
- Total Cost = Concrete + Labor + Excavation + Reinforcement
- Costs vary by location, foundation type, and soil conditions
- Strip foundations are used for load-bearing walls
- Raft foundations spread the load over a large area
- Pad foundations support individual columns
- Pile foundations are used for weak soil conditions
