topographical survey

topographical survey

HCL’s topographical survey provides accurate measurement and recording of a site’s physical features of the survey area.

The topographical survey provides a very detailed and accurate mapping of things found within the boundary of the surveyed area, and would include the terrain, access chambers, street furniture, building footprint and height, as well as its ridges and eaves.

Our topographical surveyors are trained and qualified experts in their field, and can undertake surveys in commercial, industrial, and domestic markets.

Process for a Topographical Survey

Time is spent on site to complete the survey, using instruments to collect location data. This data is then analysed before a scaled drawing is completed to reflect the results of the analysis.

Topographical surveys provide accurate information on the levels of the site. These surveys are usually requested, and used by architects, engineers, civil contractors, and landscape gardeners, to help them to progress with their designs or drawings.

Types of Topographical Surveys

There are more than one type of topographical survey, depending on the purpose of the survey and the desired output. These are; general land survey, boundary survey, and construction surveys.

General Land Surveys

Land surveys are for determining distances and angles between points on the land, and is essential for civil engineering and construction projects. Land surveys determine the three-dimensional positions of points and the distances and angles between them.

Boundary Surveys

Boundary surveys are used to identify a property’s boundary lines and are used as a means of formally defining the limits of properties. This is an essential part of property ownership. If boundary lines are contradictory, landowners may need to carry out a boundary survey.

Boundary surveys are usually carried out prior to the purchase of land, and include the measurements of the land.

Construction Surveys

A construction survey is much like a land survey and involves looking at the natural habitat of the area. This survey is concerned with the layout of the project and involve markers and reference points on the site that instruct contractors where to start building a new structure.
