Benchmark Surveys will undertake a complete building survey to include, a topographic survey of the building footprint and its location, Utility survey, floor plans, sections and elevations or any combination of these elements to suit the clients requirements.


Buildings can be very irregular in shape, especially historic buildings that will have been altered over many years and constructed using various methods and materials.


Using our Trimble X7 & TX6 3D laser scanners, reflector-less survey instrument technology and traditional disto and tape methods, the shape of the building can be accurately measured with ease.

Roof details, chimneys and other difficult to access details can be easily and safely recorded using various survey instruments and our drone. Intricate roof detailing and trusses can also be measured as long as a clear line of site is available.

Benchmark Surveys uses 3D laser scanning to produce Point Clouds, 3D models and accurate elevations for Engineers, Architects, Planners, Developers and Contractors. We can also produce floor plans and sections using this method.


Using the laser scanner we can get upto 2mm point precision in Laser Survey projects.

Laser Surveys allow us to capture high quality data in less time, please see below ways we incorporate Laser Scanning into our surveying workflow.

3D Laser Scanning using the Trimble X7

  • Essential performance – effective high speed scanning with consistent accuracy over the full scan range. The Trimble X7 delivers superior performance compared to other similarly priced laser scanners

  • High quality data – quickly capture clean data even in bright sunlight or compete darkness. Be confident you will get the quality data you need with less setups to complete the project

  • Integrated HDR camera for colouring pointcloud data. provides fast image capture to colorize scans with minimal impact on field productivity

  • Survey grade self levelling for improved speed on site.

CAD drawn elevations from Orthographic images created from the 3D pointcloud. 3D Laser Survey points are accurate upto 2mm.

3D Laser Surveys Allow us to create correctly scaled image slices of building elevations, in high resolution formats. Autocad is then used for creating linework.
