Design Procedures for a Building Foundation (Step by Step)
- Decide the Location of Columns & Foundation and Type of Loads Acting on Them.
- Estimate Allowable Bearing Pressure of Soil Using Ground Investigation Report.
- Decide Depth of Foundation.
- Calculate Foundation Area.

How do you design a foundation?
- Step 1: Transfer of axial force at the base of column.
- Step 2: Size of the footing.
- Step 3: Thickness of footing.
- Step 4: Minimum reinforcement.
- Step 5: Check for the gross base pressure.
- Step 1: Size of the footing.
- Step 2: Thickness of footing slab based on one-way shear.
- Step 3: Checking for two-way shear.
How do you determine your foundation design?
General factors to be considered for determining depth of foundation are:
- Load applied from structure to the foundation.
- Bearing capacity of soil.
- Depth of water level below the ground surface.
- Types of soil and depth of layers in case of layered soil.
- Depth of adjacent foundation.
Can I make my own house foundation?
Building a good foundation requires a lot more than digging a hole and pouring some concrete into forms. It must be tailored to its site like a custom suit, taking into account soil conditions, water tables, even the quality of the backfill.
What are the requirements of good foundation?
What are the Requirements of a Good Foundation?
- Permanence. It’s essential for foundations (and the building itself) to be placed in an area in such a way that it will not be affected by future construction work or projects.
- Stability and Cohesion.
What material is needed for foundation?
Concrete is the best material for foundation among all other materials used for foundation because it is hard, durable, and strong in compression. Concrete does not affect by moisture and can be made nearly watertight for basement walls. It can easily casted in any shape required for each foundation.
How deep should a foundation for a house be?
Depth of Footings Footings should extend to a minimum depth of 12 inches below previously undisturbed soil. Footings also must extend at least 12 inches below the frost line (the depth to which the ground freezes in winter) or must be frost-protected.
How is foundation depth measured?
Measure from where the concrete foundation starts above ground to where it meets the footer using a tape measure. This will give the measurement of the depth of the building’s foundation. Dig outward from the foundation until you reach the edge of the footing.
What are the two essential requirements of the design of foundation?
The foundation must be feasible, both technically and economically, and practical to build without adverse effects on surrounding property.
What are the 3 types of foundations?
Foundation types vary, but likely your house or home’s addition does or will have one of these three foundations: full or daylight basement, crawlspace, or concrete slab-on-grade.
What are the five types of foundation?
There are five main foundation types and a handful of important variations.
- Basement Foundation.
- Crawlspace Stem Walls.
- Concrete Slab Foundations.
- Wood Foundations.
- Pier and Beam Foundations.
How much of my foundation should be exposed?
Typically the codes say the amount of exposed foundation should be between a minimum of 4 and 6 inches above the finished soil that touches up against the foundation.
