3D scans of Forth Bridges to power educational games and learning.

Incredibly detailed 3D scans of the Forth Bridge will form the basis for interactive games promoting engineering skills for school children, it has been revealed.

First announced in 2014, the £300,000 scanning project was one of the most challenging and complex 3D scans undertaken anywhere in the world. It has amassed a data-cloud of many billions of dimensionally accurate points on the structures of the Forth Bridge, Forth Road Bridge and the partially built Queensferry Crossing.

Now a further grant of £425,000 from Transport Scotland has enabled Scottish digital heritage experts to start work on learning games, augmented reality apps, real-time interactive models for virtual headset tours and video fly-throughs for release in 2018, all aimed at developing STEM skills among pupils in Scottish schools.

In the meantime, the project has released a stunning animation of the “point cloud” data of the Forth Bridge and Forth Road Bridge https://youtu.be/ikLjgXXAMas 

Transport Scotland funded the project on behalf of the Forth Bridges Forum and the laser scanning and digital development work has been carried out by the Centre for Digital Documentation and Visualisation (CDDV), a partnership between The Glasgow School of Art’s School of Simulation and Visualisation and Historic Environment Scotland.

Transport Minister Humza Yousaf said:

“The Forth Bridges represent Scotland’s industrial past, creative present and our dynamic and innovative future. They are the pinnacle of world-leading design and engineering and it’s right that we conserve and protect them and also seek to inspire and educate the young engineers of the future.

“If the bridges are a globally unique showcase of Scotland’s world-class engineering skills, this amazing 3D scanning project also showcases the world-leading design, research and innovation in our Higher Education institutions.

“The possibilities for this comprehensive digital data are almost endless. It allows the production of detailed information and tools for conservation, educational resources, improving accessibility and delivering virtual records to help health and safety training as well as promoting tourism.

“It is already delivering early benefits. Our commitment to the work was a crucial element in securing World Heritage status for the Forth Bridge last year (2015). In addition, the Forth Road Bridge scans had only just been undertaken when maintenance issues forced the prolonged closure of the structure last winter. I understand the engineers were able to use the scans as part of diagnosing and solving the problem with the truss-end links.

“But now, rightly, our focus is education and creating learning tools to educate and inspire the young engineers of the future.”

The laser scanning work began in May 2015 and involved a total of 90 days digitally documenting the bridges on foot, from ropes, vehicles and boats. Mobile mapping was undertaken in partnership with Leica Geosystems UK. It has created a huge point cloud mapping the structures and their overall physical footprint over 3.6 square kilometre.

It has also been one of the most complex 3D scanning projects undertaken anywhere in the world given the vagaries of the three different structures and physical and environmental challenges faced by the team.

Alastair Rawlinson, Head of Data Acquisition at The Glasgow School of Art and CDDV said:

“Laser scanning each of the three bridges has posed unique challenges for our team. We have had to use our combined experience, gained through digitally documenting globally iconic structures such as the Sydney Opera House and Mount Rushmore to create innovative methodologies to allow us to capture these incredible bridges in great detail.

“We will now use this specialised 3D dataset to develop interactive learning resources based on advanced gaming technologies and virtual reality to make the information accessible to school children across Scotland and beyond.”

Miles Oglethorpe, Head of the Industrial Heritage team at Historic Environment Scotland which was responsible for preparing the successful World Heritage nomination of The Forth Bridge, said:

“Having such an extraordinary, detailed and accurate 3D record of The Forth Bridge is a tremendous advantage for us as we set about sharing Scotland’s sixth World Heritage Site with the World.

UNESCO expects us to celebrate our World Heritage, and to convey it to as big an audience as possible. The latest digital technologies not only make this possible, but also allows us to consider ways of tackling some of the wider recording issues facing other World Heritage Sites across the world.”

A panel of experts, including school teachers, Napier University and the Institute of Civil Engineers, is helping CDDV develop options for the data. The work is now focusing on highly detailed models of the bridges and a suite of education materials including two digital learning games based on building the Forth Bridge for school children, an augmented reality app to showcase the industrial heritage of the bridges and a virtual reality headset-based “virtual tour” of the Forth Bridge and Forth Road Bridge. The materials are expected to be rolled-out in mid-2018.
