This type of survey involves measuring all the buildings, structures, fences, improvements and services on a block of land and producing an accurate survey plan with levels and contours . The surveyor will place a datum nail in a suitable position such as the road bitumen and this will provide a reference point for which all heights on the survey plan can be referred to. If you are building / extending a new home or commercial building, constructing boundary walls or subdividing a property, a feature survey will be required as part of the design process . A feature survey plan is an important tool used by builders, designers, architects and developers and will usually be an initial requirement to obtain a building development approval or building license.
