A topographic survey is an essential start for any planned development of an area. All ground features will be accurately mapped in three dimensions to provide a scaled plan to the requirements of the client. A survey may vary from, for example, a large scale at 1:1250 or 1:2500 for the purposes of locating a solar panel farm to a small scale of 1:100 for a single dwelling development. With our reflectorless survey instrument we can gain with ease ridge and eave heights of buildings, structure heights, overhead cables, tree heights and inaccessible detail such as neighbouring private properties, overlooking windows or bridge structures. With a variety of survey equipment we will endeavor to locate all information that is required for each individual site.
All surveys can be output in a number of formats to suit the client. Where the client has their own specific coding and layering system these will be used. All data can be shown in .DWG, .DXF, .PDF, MX Genio Moss or XYZ text listing. All surveys can be output in 2D or 3D format.
Benchmark Surveys uses Trimble total stations and Trimble GPS equipment for topographic surveys. The variety of equipment we use gives us the flexibility to carry out surveys on a local grid / local datum basis or tied to Ordnance datum via conventional benchmarks or more usually now tied to Ordnance Survey in coordination and level by GPS fix. For large scale surveys a scale factor can be applied to the survey data or a factor of 1 can be used.
