Professional Drone Surveys for Construction and Earthworks

UAV Surveys UK provides professional drone surveying services for construction, civil engineering and earthworks projects across the UK.

​

Using drone LiDAR, photogrammetry, aerial mapping and GNSS survey control, we capture detailed information about existing ground conditions, buildings, structures, earthworks and site progress.

​

Our surveys can provide accurate, repeatable data for planning, design, construction monitoring, quantity measurement and as-built records.

Construction Site Surveys

​

Drone surveys provide an efficient way to capture detailed information across construction sites, from initial site surveys through to completion.

​

Typical applications include:

​

  • Existing site and topographical surveys

  • Pre-construction surveys

  • Construction progress surveys

  • Earthworks monitoring

  • Cut and fill calculations

  • Stockpile and material volumes

  • Site level monitoring

  • As-built surveys

  • Contractor progress records

  • CAD and GIS mapping

  • 3D site models and point clouds

  • ​

Drone surveys can also be repeated at regular intervals, providing a consistent record of how a project is progressing.

Earthworks Surveys

​

Earthworks projects often involve large areas where ground levels change throughout construction.

Drone LiDAR and photogrammetry can capture detailed terrain information for:

  • Cut and fill analysis

  • Excavations

  • Embankments

  • Bunds

  • Quarries

  • Land remediation

  • Development platforms

  • Road and infrastructure projects

  • Aggregate sites

  • Construction compounds

​

The resulting terrain data can be used to compare existing and designed surfaces, calculate volumes and monitor changes over time.

​

Cut and Fill Surveys

​

Accurate ground models can be used to assess cut and fill requirements and monitor earthworks against a design.

​

Survey data can include:

  • Existing ground levels

  • Design surfaces

  • Difference models

  • Cut and fill volumes

  • Contours

  • Spot heights

  • Cross-sections

  • 3D terrain models

​

The accuracy and suitability of volume calculations depends on the survey method, ground conditions, control, surface definition and required measurement tolerances.

​

Stockpile and Volumetric Surveys
​

Drone surveying can provide rapid measurement of stockpiles and bulk materials without requiring surveyors to physically access the pile.

​

Applications include aggregates, soil, spoil, waste, minerals and construction materials.

Surveys can produce 3D models and calculated volumes, providing a repeatable method for monitoring material quantities and changes between surveys.

Construction Progress Monitoring

Repeat drone surveys can create a visual and measured record of construction progress.

Depending on the project requirements, surveys can provide:

  • Orthomosaic imagery

  • Point clouds

  • 3D models

  • Terrain models

  • Progress photographs

  • Contours

  • Volumetric measurements

  • CAD and GIS data

Repeat surveys can also be compared to identify changes in site levels, earthworks and completed structures.

​

LiDAR and Photogrammetry for Construction

Different projects require different survey methods.

Drone LiDAR uses laser scanning to capture three-dimensional information about the ground and surrounding environment. It can be particularly useful on complex terrain and sites containing vegetation.

Photogrammetry uses overlapping aerial photographs to produce orthomosaics, point clouds, surface models and 3D models.

Where appropriate, LiDAR, photogrammetry and GNSS surveying can be combined to provide a more complete dataset.

Survey Control and Accuracy
​

Survey quality depends on the equipment, survey methodology, GNSS positioning, ground control, check points, flight parameters, terrain, processing and required deliverables.

​

Where appropriate, UAV Surveys UK can incorporate ground control and independent check points into the survey.

​

There is no single accuracy figure that applies to every drone survey. Survey requirements are assessed against the intended use of the data before work begins.

As-Built Surveys

Drone surveying can be used to document completed construction works and provide a measured record of site conditions.

Depending on the project, deliverables can include:

  • As-built topographical information

  • Orthomosaics

  • Point clouds

  • DTM and DSM surfaces

  • Contours

  • 3D models

  • CAD drawings

  • GIS datasets

  • Cross-sections and profiles

  • Survey reports

Construction Survey Deliverables
​

Typical deliverables include:

​

  • LAS / LAZ point clouds

  • GeoTIFF imagery and elevation data

  • Orthomosaics

  • DTM and DSM models

  • Contours

  • Spot heights

  • CAD drawings

  • 3D models

  • Digital terrain data

  • Cross-sections

  • Volume calculations

  • Survey reports
