Topographic Surveys

This type of survey is commonly produced at the initial stages of construction and engineering works. The entire design and planning of a project is usually based on the topographic survey therefore it is essential that the accuracy and content of the plan are sufficient for the proposed development. If the data is not correct at this stage it is quite possible that you will encounter time consuming and costly delays throughout the rest of the development.

The scale of the plan determines the amount of detail to be included. For instance a 1:1250 scale plan printed on an A1 size drawing sheet will include a large area of land but will not usually include smaller points of detail such as service covers, trees and street furniture. On the other hand a 1:100 scale plan of the same area of land can include a very large amount of detail and descriptive text but has the disadvantage of needing many more drawing sheets when printed to paper or film. The RICS scale guide gives a very good insight into the choice of scale and is well worth a read.

Since CAD programs are now used to design most projects the effects of scale are not so much of a concern. Each element of the drawing is coloured and layered in a logical sequence. This enables the Architect to produce the design directly over the survey and switch layers on and off as desired.

For most small to medium sized developments we recommend our standard specification for detailed land surveys at 1:200 scale. Please read this and have a look at the example shown which has been produced to this specification.

Don't forget that topographic surveys are not just used for construction purposes. We can also survey areas of land for landscaping, conservation, archeaology, wildlife protection, navigation and just about anything that needs a map or a plan!
