LAND / TOPOGRAPHIC SURVEYS

Techsol carry out a range of topographic surveys. A land survey for a one-off house would be relatively straightforward for example, where a topographic survey for an infrastructural project would generally follow quite a strict client specification.

We generally encourage our clients (or their advisors) to provide us with a survey specification of some sort as this ensures that all the required data is gathered and presented in a format that is instantly useful to them. Once we have provided a topographic survey for a client once, we can set up a template for that client so that subsequent surveys are similarly formatted and presented. 

In the survey specification the issues that would be addressed would include; the required accuracy of the survey, whether a particular grid system is to be employed, the features that are to be surveyed, and the manner in which data is to be presented.

Many clients now require that our topographic surveys are referenced to ITM coordinates. This is the new Ordnance Survey grid of Ireland. We use a GPS system to tie survey data to this grid. On large projects the advantages to having the topographic survey referenced to a common grid are numerous. This system facilitates ease of exchange of information between surveyors and engineers, correlation of survey data with OS mapping and setting out from design drawings.
