You know the blokes with the tripod and guy with a long measuring stick.
Anyone do it ? What are they doing what's the tripod what you checking for ?
Relative heights.Anyone do it ? What are they doing what's the tripod what you checking for ?
The height above ground level of the instrument on top of the tripod is known. That height is then compared with the height of the stick. You now know how much the road rises or falls between the two points.
This ‘long measuring stick, is it a tall thin box shape with graduations or a shiny pole with a prism on top? Depending on which depends on the type of survey. The former will just be a leveling exercise as described by the poster above to determine relative road levels, the latter would probably be a full blown topographic survey to determine not only relative levels but positions too thus producing a full 3D plan of the carriageway showing road crown, channel and kerb levels as well as the position of street furniture and the carriageway’s boundaries.
Uses of the finished survey range from below ground works to determine or improve services such as drainage and utilities, a redesign of the road layout due to new building works that need access to and from the carriageway plus other stuff such as GIS applications.
As an ex land surveying business owner we used to carry out road surveys all the time.
