Foundation Plans Mr. Sackett
Foundations • What is a foundation? What does it do? • Lowest structural component of a building upon which all other members rest • How are foundations built? • Depends on the nature of the soil, slope of the terrain, the size and weight of the structure, the climate, building laws, and relationship of the floor line to the grade line.
Types of Foundations • Wood post piles • Steel and concrete piles • Wood post columns • Masonry columns • Concrete columns • Concrete piers • Slab foundation • T-foundation
Footings • Footings-the bases of foundations and foundation walls. • Two Types: • Continuous-extend under walls, distribute weight around perimeter foundation; often wider than foundation wall • Individual-support vertical structural members
Concrete Slab Foundation • Use floor plan dimensions to lay out exterior edge of the slab. • Lots of concrete and rebar used • Can be one piece or multiple pieces
Foundation Detail (Finished Basement) • Finished basements have stairs • Label Floor Joist Sizes • Make sure to have supportive columns for your floor beams • Dimension, Dimension, Dimension • Notice Different Widths • 8”=Concrete Block • 12”=Poured Concrete Wall • 20” (Could be 24”)=Footer
Foundation Detail (Crawl Space) • No stairs • Additional support for floor beams • Vents and Access areas
The Reason We Use 8” Block on Top • If you want Brick Veneer you have to leave room for it on your foundation
Plan Out Your Drawing • Use your floor plan to outline your foundation plan • From there figure out how you will lay out your floor joists so that you will know where to put your supportive columns • Make your footers 24” and decide what foundation style you will use
Think About Your Floor Plan • Figure out how your floor joists will span your foundation and where you will need supportive columns (pg. 498)
