1 Drawing Longitudinal & Cross Sections

2 Architectural Sections
As we can see in Figure 1 the section shows us that the building has, 4 levels deep piers columns

3 Architectural Sections

4 Conventions with scale
The Horizontal scale is usually greater than of the Vertical scale e.g. Horizontal Scale 1:100 Vertical Scale 1:10

5 Longitudinal Section A section through the longer length of the job
On a Road or Driveway, a section along the direction of the road

6 Longitudinal Sections
Note – Scales Vertical is always larger

7 Notations RL – is the origin for vertical dimensions for the drawing. Chainage – is the horizontal measurements from the origin. Existing Ground Level – the ground level +/- above Datum – Is the height above the origin in this case RL

8 Formation Height Formation Height is the bulk excavation finished height

9 Notations Design Level – Is the finished level required.
Cut – Noted on this line if the existing ground is higher than the design level. Fill – Noted on this line if the existing ground is lower than the design level.
