As well as more traditional survey methods, Trumetric regularly undertake digital 3D laser scan surveys to generate complete building models and Point Clouds that contain much more accurate and reliable data than traditional survey methods, supplemented by additional data gathered from an airborne drone mounted camera to fill in the gaps that cannot be measured from ground level.
A laser scanner is a highly accurate measuring tool that uses laser light and photographs to capture data in the built environment. Every time a laser hits a solid surface, a record of a point in 3-dimensional space is generated. Collectively over multiple laser points per scan and multiple scan locations per inspection, a spatially accurate 3D point cloud is generated. This can be used to prepare all necessary drawings and models for a site or building including plans, sections, and elevations, as well as generating orthographic photographs or 3D imagery as required.

Our survey techniques can be tailored to your needs, providing as simple or detailed deliverables as your situation requires. In addition to measured data, a laser scan or measured survey can assist in other practices such as:
• Defect Diagnosis
• Right to Light Assessments
• Volume Calculations
• Preparation of CGI + Visualisations
• Planning Applications + Pre-Planning Discussions
• Preparing Visual Records of Historic Buildings
Using a laser scanner to undertake a survey is a significantly less intrusive and disruptive survey method. It can also enable a building to remain in occupation while a survey is carried while limiting any interference between our inspections and the building users, which can be undertaken quickly and with minimal interruption.
Alongside our laser scan capability, where the scanner cannot view an area (such as a roof) then we supplement this dataset with further information gathered from a camera mounted to a UAV (drone). This data can then be transformed into a matching point cloud and can merge each dataset together to create a full and more complete model. A drone is also proven to be a far safer way of gathering data in inaccessible areas, reducing inherent risks and making the survey process far smoother in what could be a difficult scenario.
