40Seven is dedicated towards providing comprehensive and accurate topographical surveys to a range of high profile clients. We pride ourselves on being able to deliver a high quality product and meeting clients delivery requirements without compromise. 

Topographical Surveys provide a detailed picture of an area of land. All features are shown to a level of detail and scale appropriate to the individual project. Surveys can be related to National (OS) Grid and Datum, generally by the use of GPS. Each surveyed point is positioned in 3 dimensions, allowing drawings to be shown with contours and spot levels, which then allow us to produce accurate ground models and 3D visualizations if required.

Dedicated software is used to turn site data into a visual representation of the area surveyed. The finished plans are generally provided in digital format, such as Autocad, which can be delivered quickly and efficiently by e-mail.

Typical Topographical surveys that 40Seven carry out are:

• Global Positioning System (GPS) surveys
• Highway surveys
• Railway surveys
• Flood plain surveys
• Water treatment works
• Pipeline surveys
• Green/Brownfield Development sites

40Seven has surveying teams based throughout the UK to enable topographical surveying services to be delivered quickly and efficiently, using the latest in modern technology. A combination of Reflector-less and Robotic Total Stations are used in conjunction with high accuracy GPS systems and modern digital levels to ensure that all our surveys meet the high standards expected by our clients.
