4. INTRODUCTION TO FOUNDATIONS
Function of a foundation is to transfer the structural loads from a building safely into the ground.
A larger and heavier building of masonry, steel, or concrete would require its foundations to go deeper into earth such that the soil or the rock on which it is founded is competent to carry its massive loads.

5. Foundation Components
Footing

6. Foundation Components
(to attach wood stud sill plate)
(moves water away from building)
(to keep water off of foundation wall)
(separates slab from foundation wall)
(to keep water off of slab)
(to keep water off of slab & moisture barrier)
(moves water away from building)

7. Site Preparation Remove trees and any debris
Remove top soil (4-6” below surface)

8. Site Layout Ensure lot lines are known & setbacks are complete
Layout building perimeter
Use batter boards
Establish building corners & building perimeter
Use surveying instruments

9. Excavation Excavate foundation along line created by batter boards
Excavate remainder of soil inside perimeter
Don’t excavate inside soil if slab on grade
If deep foundation, taper edges to prevent collapse
If soil unstable, or very deep - use shoring

10. Pour Footings Construct formwork (if required)
Install reinforcement (rebar) for footings
(protrudes above footing to tie-into foundation wall)
Pour concrete footings
Smooth / finish surface

11. Rules of Thumb Footing shall be below frost line
Footing width usually 2x height
Typical size (24” wide x 12” tall)
Rebar is usually 3” from edge of concrete
Crawl spaces should have rigid insulation along the interior face of the foundation wall

12. TYPES OF FOUNDATION Major Building Parts Superstructure Substructure

13. TYPES OF FOUNDATION Two types foundations : Shallow and Deep –
Depends on whether the load transfer is at deeper depths or shallower depths
- Need for these two types (soil strength, ground water conditions, foundation loads, construction methods and impact on adjacent property)

14. TYPES OF FOUNDATION
Shallow foundations (column footings without or with tie/grade beams, individual or combined wall footing, slab on grade, raft)
- Deep foundations (caissons with or without sockets, end bearing or friction piles, pile groups), made of concrete (regular or site-cast) or steel or wood

15. Shallow Foundations Requirements Suitable soil bearing capacity
Undisturbed soil or engineered fill
Basic types or configurations
Column footings
Wall or strip footings
