Topographic Surveys

South West Surveys is the first port of call for topographical surveys. We travel throughout the UK offering highly detailed and precise surveys to every sector at affordable prices. Each site we visit is different, yet what we record is the same throughout whether it be natural or manmade features, our survey shows every piece of detail.

Our surveys are delivered in PDF & DWG files and can be produced in 2d or 3d.

What are Topographical Surveys

A topo survey, also known as a land survey, provides an accurate representation of natural and manmade features within a specified area. They are usually undertaken by land surveying companies by using a range of survey equipment that can be used to measure and identify angles and distances effectively.

To obtain precise measurements, land survey companies will often use GPS survey equipment in order to locate fixed points of an area of land. These points are used as reference markers and they are used to demonstrate the height and base of the specified area. With these markers you can produce a CAD (computer-aided-design) drawing, which illustrates a highly detailed and accurate topographical map of your land.

Why You May Need a Topographical Survey

Topographical surveys are typically developed for architects, contractors, engineers and designers. However, they can be useful for anybody who requires a survey. They are most useful when working on land progress projects, and they can help to avoid any complications in the process of development. When working on a design a land survey can provide you exact and precise plans and coordinates to help you get creative in the planning and layout process.

The Benefits of a Topographical Survey

Topographical building surveys serve many purposes and when compared to other survey techniques, they can be just as or even more beneficial:

-Can identify existing conditions and issues with a site

-Illustrate how building features can be constructed electronically, by using CAD

-Demonstrates any obstacles that may cause problems with the site’s development

-It provides information that can help designers create suitable designs fitted to the specified land

How We Conduct Topographical Surveys

The type of equipment for a topographic survey varies depending on the land and preferences of the surveyor. Environmental conditions will be considered when selecting the appropriate tools in order to attain ultimate accuracy. In wider and more open spaces, the assessor will utilise a GPS signal as it is less likely that large obstacles will interfere with the survey.

In industrial areas, a GPS system is not suitable. Therefore, a robotic total station instrument will be used instead, which is used to measure horizontal and vertical angles as well as sloping distances. However, if an area is inaccessible or too dangerous to collect data, we use reflector-less technology.

We can carry out basic surveys, picking up only key features if required, but surveys usually include all detail including trees, shrubs, roads, paths, inspection chambers, drainage covers and invert levels etc.

Once the data has been collected from either one of the survey techniques, it will be stored electronically. The data is then processed on a computer to produce the final drawing on CAD.

The Types of Sites We Survey

We are equally adept at producing surveys for green sites and urban sites. Sites benefitting from a topo survey vary from private residential alterations to large scale developments, roads, railways, farmland, civil engineering projects etc.

Clients include private property & land owners, architects, engineers, utility companies and developers. Whether you are looking to develop a small plot of land for a new home or undertaking a major infrastructure project that spans hundreds of acres, our surveyors can create the plans you need to move your project forward.

Topographical survey drawings are provided in CAD 2D and/or 3D as required and in PDF format. Paper and film copies can be supplied if requested.

Getting a Topographical Survey

We work on projects throughout the whole of the UK, but our close proximity to the South West means we’re perfectly positioned to carry out topographic surveys in and around Bristol, Bath, Cheltenham and Gloucester.
