  1. CE 303: Introduction to Construction Blueprint Lab

  2. Dimensioning 1’ - 8” 4” 8’ -

  3. Objectives • Dimension Lines • Reading Drawing Scales • Architectural • Engineering • Stationing • Line-types and Placement • Introduction to Quantity Takeoffs

  4. Drawing Scale • construction projects are drawn to a reduced scale • scale is defined as • architectural scale • 1/4” = 1’-0” this means every 1/4” on the drawing equals a one foot of actual length on the project • 1/8” = 1’-0” • engineering scale • 1” = 10’, or 20’ etc. • metric scale • 1:50

  5. Reading Scales architectural scale 2’ 1 inch 4’ 1 inch 2’ 2 inches 2 inches 16’

  6. Reading Scales 4” 2’ - architectural scale 20’-6”

  7. Reading Scales architectural scale 2’ - 8½”

  8. Reading Scales 3’-8” architectural scale 5 5/8”

  9. Reading Scales 100 feet 50 feet 1 inch 1 inch 10 feet engineering scale

  10. Reading Scales 2 meters 10 meters metric scale

  11. Stationing • Dimensioning of an alignment in 100 foot intervals. • Each 100 ft. is denoted as 1+00 • 100’ = 1+00, 200’ = 2+00, etc.. • Known as full stations • Intermediate stations are between full stations and are known as plus stations. • 147’ = 1+47, 357.24 = 3+57.24, etc…

  12. Line-types & Placement • Dimension and Extension Lines. • Marking device placed at end of dimension line • Arrows, dot, tick… • Extension lines are drawn perpendicular to dimension line to specify features between which the dimension applies.

  13. Dimension Lines

  14. Quantity Takeoffs • Quantities derived from drawings • Square footage, linear footage, cubic footage… • List of all materials • Requires understanding of geometry (calculations from straight lines, curves, angles...) • Accurate quantity takeoffs are required for detailed cost estimates. • Can include labor and equipment costs
