From Reality to Documentation: Mobile Mapping Revolutionising As-Built Documentation


As-built documentation

In construction, accurate and up-to-date documentation is vital for successful project management. Traditional methods of capturing as-built data are often time-consuming, prone to errors, and limited in providing comprehensive information. However, mobile mapping technology is revolutionising the process. By utilising advanced sensors like LiDAR scanners and high-resolution cameras, mobile mapping enables real-time data collection, resulting in increased accuracy, efficiency, and accessibility of as-built documentation.

High-Precision Data Capture: Traditional methods, such as manual measurements and photographs, are labor-intensive and can lead to fragmented and outdated documentation. Mobile mapping offers high-precision data capture, allowing for detailed measurements of physical structures and their surroundings. It integrates high-resolution imagery to provide a comprehensive representation of the environment.

Efficiency and Time Savings: Mobile mapping significantly improves efficiency and time savings. It enables rapid data collection in a single scan, eliminating the need for multiple site visits. Simultaneous capture of multiple data types streamlines the process, removing the requirement for separate measurements and documentation.

Informed Decision-Making: Accurate and comprehensive as-built documentation plays a crucial role in project management and maintenance. With mobile mapping, project managers can make informed decisions based on accurate data, reducing errors and rework. Detailed documentation simplifies future modifications and renovations, saving valuable time and resources.

Enhanced Accessibility and Visualization: Accessibility and visualisation are enhanced through mobile mapping. Stakeholders can remotely access digital representations of the captured data, facilitating exploration and analysis from various devices. The 3D visualisation capabilities offer a realistic representation of the environment, improving understanding and communication among project teams.

Mobile mapping technology revolutionises as-built documentation by providing accurate and comprehensive data capture, improving efficiency, enabling real-time updates, and enhancing accessibility. It addresses the limitations of traditional methods, transforming the construction industry’s approach to documentation.


  1. Mobile Laser Scanning: Use mobile mapping technology with LiDAR sensors to rapidly capture highly detailed point cloud data of the project site.
  2. Drone Mapping: Deploy drones with high-resolution cameras to capture aerial photographs and generate precise 3D models and orthomosaic maps through photogrammetry, ensuring a complete 360° dataset of the project site.
  3. Cloud-Based Processing: Process the collected data, including point cloud data from laser scanning and imagery from drone mapping, using cloud-based software for efficient analysis and faster results.
  4. Exporting Point Cloud Data and Alignment: Export the processed point cloud data in standard file formats, ensuring compatibility with different software applications. Perform alignment of multiple scans to create a cohesive representation of the entire project site.
  5. Registration and Model Creation in Autodesk Revit: Register the exported point cloud data within Autodesk Revit. Create the as-built model in Autodesk Revit, incorporating dimensions, materials, and annotations to accurately reflect the real-world environment.
  6. Quality Check: Conduct a thorough review to ensure accuracy and completeness of the modelled elements, comparing them with the captured point cloud data and 360° Reality Model. Address any discrepancies or errors to ensure a reliable representation of existing conditions.
  7. Deliverables: Delivery of Model, Floor Plans & 360° Reality Model: Prepare deliverables, such as the finalised as-built model, floor plans, sections, elevations, and a 360° reality model combining the as-built model with high-resolution imagery. Distribute these deliverables through various platforms to facilitate ongoing management, maintenance, and future modifications.
