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