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.

10. Cross Section
Measurements taken from Centreline

11. Notation
