Created by 3D technology and creative production company Inition, the interactive platform offers an insight into how the tunnel will be constructed.
London's existing sewerage system was designed in the Victorian era, and when it rains heavily, an estimated 39million tonnes of untreated water overflows into the River Thames.
The Thames Tideway Tunnel Scheme is designed to absorb this excess water, greatly improving the river quality and achieving European environment standards.
Visitors to Stand C80 at the 2013 Engineering Design Show will be able to see a physical model of a cross section of a typical riverside London street area, from above ground to below the Thames river, along with the underground tunnel structure underneath.
The mixed media tool allows people to 'Build the Thames Tideway Tunnel' for themselves using an iPad app to trigger various construction stages, such as driving a tunnel boring machine, building a CSO inception site and landscaping the public areas.
Finer, above ground details such as buildings, cars, lamps and Boris bikes have also been 3D printed by Inition to enhance the user experience.
"The Thames Tideway Tunnel is an incredibly ambitious engineering project that will affect many aspects of the community," said Stuart Cupit, Inition's technical director. "By mixing augmented reality, 3D printing and traditional model making, visitors can engage with the proposals in an intuitive, accurate but entertaining way."
