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

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