  1. Plans and Specifications Reading to Build

  2. Starting Your Project • Determine your needs • Plans • Materials • Tools • Plans are needed to determine materials • Once you have materials, you can decide on tools needed

  3. Building Plans • Collection of original drawings showing • How to build • Specifications of the build • Materials to use • Also known as blueprints • Can plans be the same size as the project? • What do you do? • Draw to scale!

  4. Reading Scale • Think about a ruler • How do you use it? • Think of how you break down an inch

  5. Reading Scale • We have a building that is 100 feet long. • How big of a piece of paper would we need? • Full size • 100 feet • 1 inch = 1 foot • 100 inches • ½ inch = 1 foot • 50 inches • ¼ inch = 1 foot • 25 inches • 1/8 inch = 1 foot • 12.5 inches

  6. Reading Scale • Difficult to always try to measure with a ruler and convert • Architect’s Scale • Special type of ruler to help you make the conversions in one easy measurement

  7. Reading Scale • Scale has numerous sides with numerous scales • Scale marked on the side • Align the number on the scale with the scale your drawing is • Numbers printed will then help you determine feet

  8. Reading Scale • Numbers tell you whole feet • Not everything is in whole feet • Use the small hashes at the end • Be sure you know the division! • Look at number of marks • See the relationship to 1 foot

  9. Reading Scale • ¼ scale • Each hash mark = 1 inch • 12 hash marks  12 inches in a foot  12 ÷ 12 = 1

  10. Reading Scale • 1/8 scale • Each hash mark = 2 inches • 6 hash marks  12 inches in a foot 12 ÷ 6 = 2

  11. Building Plans • Pieces of a Plan • Plot plan • Foundation plan • Floor plan • Elevations • Sections • Details
