What is Topographical Survey?
Topographical Survey is a measurement of the land and showing exact psition of features on and around the area being mapped, levels of the ground being surveyed, building footprints, permanent structures, any building remains, onsite building heights: Ridge, Eaves, Flat Roofs; surrounding building heights: Ridge, Eaves, Flat Roofs; individual trees, all services covers/utility covers where visible
The survey will produce 2D / 3D drawing with contours and confirm with band A in both height and plan accuracy (from Measured Surveys of Land Building and Utilities 3rd Edition-RICS guidance)
The survey coordinate, and datum is based on permanent control stations that are established on and around the unit. These is referenced to the Ordnance Survey (OS) National Grid and Datum using GPS measurements. Station heights will be cross checked to the local recorded benchmarks in the area, if still available.
Our surveyors using precise Leica instruments for measurements and latest software for data processing and drafting can produce fast and cost effective surveys.
