Day 3 of the GEOBIM panel started with Ananya Narain, VP- Commercial Consulting, and Geospatial World, India talking about how cities in a built environment are a key engine for economic drivers. She talked about how by 2050 there will be rapid urbanization with 70% of the population of the world living in cities. She pointed out how 75% cities generate carbon emissions and 75% of raw materials are consumed in cities with 39% of the energy consumptions being in the AEC (Architectural Design, Engineering Design and Construction Services).This has all necessitated an urgent need to move towards digitalization.
Interoperability of BIM & GIS
The plenary session was moderated by Pieter Van Teeffelen, Director of digiGO who talked about how Geospatial and BIM should not be treated as different entities but as one, converging into GEOBIM.
The Key benefits in bringing these two technology are many. That includes faster plan approval and permits, improved coordination and collaboration, reduced construction cost and reduced material cost. GeoBIM is fundamental to Digital Twin.
The merging of geospatial and BIM technologies has brought a transformation in our approach towards the planning, building, and maintenance of structures.
When geospatial data is combined with BIM, it can lead to the creation of precise and intricate digital models of constructions and their surrounding areas.
Marek Suchocki, Head of Industry Associations Strategy, Autodesk, UK talked about how BIM supplies detailed information about built assets and GIS Provides information about assets in the context of the built and natural environments. He quotes on how, “GIS informs BIM and BIM fuels GIS.”
He touched upon the industry challenges and talked about project complexity and how projects are poorly delivered because data is not managed effectively.
There is an increasing demand for BIM and GIS interoperability and we are not leveraging readily available potential. With this convergence to GEOBIM, 13 days of an average project cost can be saved, with 90 days of construction time saved.
Predictive Digital Twin
The Moerdijk bridges in the Netherlands are bridges that connect the Island of Dordrecht with the Dutch province of North Brabant (Noord-Brabant) across the Hollands Diep. Roeland Allewijn, Chief Data Officer, Ministry of Water and Infrastructure (Rijkswaterstaat), Netherlands talked about predictive Digital twin for renovation and replacement of steel bridges, in the Moerdijk bridges. He talked about the need for replacement and renovation necessary for the 178 steel bridges in the in the upcoming decades. Timing of the replacement is important.
He talked of the four main system layers with the first layer being the asset layer where sensor techniques are used.
The subsequent layer is the data layer where there is access to metadata and BIM and here the important challenge is to store data.
Third is the Processing layer followed by the Visualization layer where Geospatial data in 3D layer is used.
The amalgamation of geospatial and BIM data can enhance collaboration among stakeholders and help them make better-informed judgments, leading to a more sustainable and efficient built environment.
