Drawing Longitudinal & Cross Sections

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

Architectural Sections

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

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

Longitudinal Sections Note – Scales Vertical is always larger

Notations RL 100.000 – 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 100.000

Formation Height Formation Height is the bulk excavation finished height

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.
