Gatwick Airport - Scan to BIM for PAVA System Design

Our team was tasked with creating an accurate 3D model of one of Gatwick Airport's gates to support the design of the PAVA (Public Address and Voice Alarm) system. Due to the lack of sufficient 3D data and the limitations of available 2D drawings, which could not capture the complex geometry of the gate, we proposed the use of the Scan to BIM process.

 

Being one of the busiest airports in the world, we decided to use the Navvis VLX, a cutting-edge 3D laser scanning system. This choice allowed us to capture the gate’s detailed data in less than 2 hours, minimizing disruption to operations and ensuring that the scan was completed without interrupting gate activities. The scan provided millions of data points, creating a precise point cloud representation of the gate’s structure.

 

The point cloud data was processed and used to generate a highly accurate BIM model in SketchUp, with specifications tailored to integrate seamlessly with the PAVA design software. This 3D model provides a comprehensive, digital representation of the gate, allowing for the optimal placement of the PAVA system and enhancing the overall design efficiency.

The Scan to BIM approach not only addressed the challenges posed by missing or outdated data but also offers a long-term solution for maintenance, upgrades, and future integrations at Gatwick Airport
