Reclaiming the Subterranean No Man’s Land of Paris La Défense

In contrast with above-ground spaces, the underground layers of our cities are not extensively mapped. The Ville 10D National Research Project is developing a 3-D modeling tool to aid visualization of the subsurface layer, toward a more holistic and collaborative approach to future planning that can turn these unused voids into active settings for urban life connected with the rest of the city.

Innovative Technologies for Planning and Designing Underground Space

A project by AECOM and the Hong Kong Special Administrative Region’s Civil Engineering and Development Department (CEDD) showcases the power of strategically layering innovative technologies to create a more holistic picture of the space below ground. This article shares how a blend of VR, BIM, photogrammetry and 3D spatial data are being used for multi-dimensional analyses and enhanced collaboration during the design process of underground spaces.  

The key to enabling faster, better and smarter design, planning and delivery of the built environment lies in a new form of infrastructure. One that is built not with bricks and mortar, but with data and artificial intelligence based on Building Information Modeling (BIM) and enabled by ever-faster data transfer speeds.


Below-ground projects in Paris and Hong Kong provide a glimpse of two ways technology is enabling new approaches that utilize virtual and mixed reality to bring underground space to life.
