How We Surveyed 13 Industrial Units UK wide in 4 Days

How We Surveyed 13 Industrial Units UK wide in 4 Days


Conducting a measured survey of industrial units across the UK demands precision, efficiency, and accuracy. This case study outlines the successful execution of a measured survey encompassing 13 industrial units scattered across the UK within a tight timeframe of 4 days, leveraging advanced technology such as the GeoSLAM laser scanner.

The client, a property management firm, required comprehensive measured surveys of their industrial units situated in different regions of the UK. Traditional survey methods would have been too time-consuming, prompting the adoption of innovative solutions like the GeoSLAM laser scanner. This cutting-edge technology offers rapid data capture with high precision, ideal for large-scale surveys within constrained timelines.

Project Planning:
Prior to the survey, meticulous planning was essential. The team outlined the logistics, scheduling, and necessary resources to ensure a smooth execution. Each industrial unit was geographically mapped to optimize travel routes and minimize time spent commuting between locations. Additionally, tenant permissions for accessing the properties were required to facilitate seamless operations.

Equipped with the GeoSLAM laser scanner, a team of surveyors embarked on the ambitious project. Upon arrival at each industrial unit, preliminary inspections were conducted to identify key areas for scanning. The GeoSLAM scanner, known for its portability and ease of use, was deployed to capture detailed 3D data of the interior spaces. The scanner’s rapid data acquisition capabilities enabled efficient coverage of all areas within each unit.

Data Processing:
Following the completion of scans at all 13 industrial units, the acquired data was processed using specialized software. The software facilitated the registration and alignment of individual scans, ensuring seamless integration into a unified 3D model. Advanced processing algorithms corrected for distortions and noise, enhancing the accuracy and fidelity of the final dataset.

Analysis and Deliverables:
With the 3D models generated from the scanned data, comprehensive analyses were conducted to extract valuable insights. Measurements were undertaken in CAD software. Floor plans were derived from the 3D models, providing comprehensive documentation for future reference and decision-making.

Results and Benefits:
The measured survey of 13 industrial units across the UK was completed within the stipulated timeframe of 4 days, showcasing the efficiency and efficacy of the GeoSLAM laser scanner. The client received accurate, detailed, and actionable plans and floor area values essential for property management, maintenance, and planning. By leveraging advanced technology, the project not only met but exceeded expectations, demonstrating the potential of innovative solutions in the field of surveying.

The successful execution of the measured survey using the GeoSLAM laser scanner underscores the importance of leveraging cutting-edge technology to streamline operations and achieve superior results. By embracing innovation, surveying firms can overcome challenges associated with large-scale projects while delivering exceptional value to clients.

This case study highlights the transformative impact of advanced surveying technologies in optimizing efficiency, accuracy, and productivity in the built environment sector.

NIA & GIA – What’s Included?

What is GIA and NIA and what is the difference?


Gross Internal Area (GIA)– is the area of a building measured to the internal face of the perimeter walls at each floor level. The building area is reported as the sum of all floor areas.

This includes all internal areas and features such as:

  • Columns
  • Toilets, shower rooms etc.
  • Voids over stairwells
  • Lift rooms
  • Corridors and circulation areas

The Areas of the building excluded for Gross Internal Area are:

  • Perimeter wall thickness
  • External balconies
  • Canopies

Gross Internal Area has several applications these are:

  • Building Cost Estimation
  • Valuation
  • Rating
  • Property Management/Service Charges


Net Internal Area (NIA) – is the usable area of a building measured to the internal face of the perimeter walls at each floor level. The building area is reported as the sum of all floor areas.

The areas included are:

  • Office/Workspace area
  • Areas occupied by nonstructural walls
  • Kitchens
  • Built in cupboards
  • Areas occupied by skirting and trunking


As NIA provides the usable floor area of a building it means that there are features and areas which must be excluded from the total floor area to calculate NIA. These include:

  • Entrance Halls used in common
  • Toilets, shower rooms etc.
  • Stairwells
  • Corridors and circulation used in common
  • Internal structural walls
  • Areas under 1.5m
  • Unusable areas which distance between opposite faces of walls is less than 0.25m
  • Heating and cooling apparatus extruding more than 0.25m into the usable area.
