3D Laser Scanning Buildings High Definition Surveying

Applications and uses of 3D Laser Scanning in surveying.


3D laser scanning is a versatile tool that can be applied to a multitude of surveying challenges.

Laser scanning can be used to complete traditional survey tasks to a new level of precision and detail.

In addition point cloud data can be used to map and model our surroundings for a host of new applications including:

Topographical land surveys showing building footprints, levels, surface features, trees etc

Detailed building elevation drawings, floor plans, sections, internal and street scene elevations.

Mapping of utilities including power lines, newly laid cabling and piping.

Accurate modeling of machinery, for example factory plant, ducting and for the oil/gas industry.

Engineering excavation models of land fill, mines and quarries for volume calculation.

Recording archaeological artefacts and features.

Archiving for historical records in event of a fire or other incident.

Business Information Modeling (BIM) using laser scanner. Avoid spatial conflicts when installing new plant systems to old buildings.

Railway infrastructure mapping and monitoring.

Coastal monitoring, capturing cliff recession over time, slope stability and beach profile changes.

Highway surveying with minimal traffic management required.

Accurate mapping of tree canopies, girth and crown heights.

Deformation surveys of buildings, bridges, power stations, refineries, dams etc.

3D visualisation and modeling.

Highway Road Corridor Surveying

Highway survey requirements are very detailed and can include road features and 3D level information, signage, line markings, boundaries and services. The terrestrial laser scanner captures all this data which is then extracted in the office to the specification requested, normally in the form of a multi layered 3D CAD drawing.

Coastal Erosion Monitoring and Recording

We are using point cloud data to monitor cliff recession rates and beach profile change on the North Norfolk Coast. The biannual laser scan survey enables engineers to compare data over time and gain an accurate picture of the cliff stability and recession. The cliff edge can be mapped from a safe distance .

Traditionally Difficult Buildings to Survey

Old buildings can set a difficult surveying challenge, containing many complicated and unique shapes and features, making them hard to measure and map precisely. Individual elements; beams, ceiling details, stonework and brick work can be accurately recorded in the office from the "collect all" point cloud approach.

Volume and Quantity Surveying

By comparing surface models of point clouds we can accurately calculate the volume of aggregates removed from a quarry over time more precisely than by using a total station. The remote nature of the laser scanner also enables access to difficult areas and reduces the risk involved to site workers and the surveyor.
