Simple construction surveying for rural applications

This booklet has been conceived as an attempt to present surveying in a generic form by applying geometric concepts without using mathematics. Though abstractions are deliberately not shunned, the presented line of thought is definitely a practical one. Construction surveying offers a very practical context within which to illustrate what surveying is about. The qualification ‘simple’ has been included in the title to express the idea that the technological level of measurement techniques presented is ‘intelligible’ and ‘understandable’. This qualification certainly does not imply an ‘unsophisticated’ or ‘naive’ approach to underlying surveying concepts.

‘To construct’ means ‘to build’ or ‘to put together’. The purpose of construction surveying is to carry out surveying measurements required for the realisation of a construction on a site. Such a construction might be a road, a school, a canal, a storage dam, or the like. What has to be ‘surveyed’, and how the required measurements must be accomplished, depends on both the construction and the site. A site cannot be described geometrically by means of a site map alone. A map describes a site geometrically, but in a horizontal sense only. In many cases, a site needs also to be described geometrically in a vertical sense. This is enabled via so-called ‘sections’.
