To draw Cross sections of a proposed road from obtained level data.

Object: To draw Cross-sections of a proposed road from obtained level data.

Theory:

The term cross-section generally refers to a relatively short profile view of the ground, which is drawn perpendicular to the route centerline of a highway or other types of linear projects. Cross-sectional drawings are particularly important for estimating the earth volumes needed to construct a roadway; they grade elevation for the road base.

Instruments required:

Field book, Graph sheet, Pencils, etc.

Procedure:

1. There is no difference in procedure between profile and cross-sectional leveling except for the form of field notes.
2. Cross-section rod shots are usually taken during the route profile survey in the same instrument positions used to take rod shots along the centerline.
3. Cross-section data are obtained at the same locations along the route that are used for the profile rod-shot stations.

Result:

The Cross-sectioning is carried out as specified and the obtained level data is used to plot the profile on a Graph sheet in MS Excel.
