In the past, going underground was a journey into unchartered territory, but the combination of technologies such as Virtual Reality, photogrammetry, Building Information Modeling (BIM) and 3D spatial data is making below ground development a much less risky prospect.
Normally there is a long history of using underground space for parking and facilities, many of these projects are simply an extension of the building on top of them, with limited connection to the city around them.
As urbanization continues its upward trend and our perceptions of space — personal and public — are constantly evolving, this use of layered technologies to explore the underground holds the potential to revolutionize urban liveability and create synergies with the surrounding urban context.
COSMOS IVICSA has undertaken a study of underground development in an urban space, has explored ways of integrating the latest innovative technologies, including Virtual Reality (VR) and photogrammetry technologies with more widely used techniques in the industry, such as Building Information Modeling (BIM) and 3D spatial data to improve communication among the different parties involved in the planning and design process of underground space.
This novel combination of technologies has resulted in time savings, increased efficiency and cost benefits as well as greatly enhanced cooperation and the ability to virtually collaborate without the need for travel to a project site. On one project, outlined below, the use of photogrammetry technology to create a 3D model of the existing site saved three weeks time from the site survey, while sharing the site reality model with the designer for performing the parametric design saved another two weeks. Integrating various feature models into a visualization model for the Virtual Reality simulation saved another two weeks by amalgamating information to form a holistic review with different parties. Further, it saved client comment time as 3D visualizations facilitate the design detail and constraints of the project.
