If you are considering property developing, contour surveys should become your new best friend. It is important to understand the contours of land. It is found that many of clients do not understand what a contour survey is and why it's necessary.

In the property world, a contour is an outline of a mass of land. A contour or detailed survey is done by a surveyor and required before starting on the design of your buildings. Contour lines will be marked on the survey. Below are some important points covered in an contour survey:

• All points on a contour line are of the same elevation.

• No two contour lines can meet or cross each other except in the rare case of an overhanging vertical cliff or wall

• Closely spaced contour lines indicate steep slope

• Widely spaced contour lines indicate gentle slope

• Equally spaced contour lines indicate uniform slope

• Closed contour lines with higher elevation towards the centre indicate hills

Once the architect or draftsperson has a contour survey then they can begin work on the plans and the survey will indicate how much site works may be required. The surveys conducted by Dolphin engineering services give you the exact data that you need so as to start developing your site.
