Digital Twin

A quick insight into the construction of Karlskrona Municipality's City Information Model

It started with a 3D model

  • 3D group consisting of representatives from plan, building permit and GIS.
  • From ESRI's ArcGIS platform, we built up LOD1 from point clouds from Lantmäteriet's flight scan, LOD2 with boxes that were refined by hand application to get the roof shape. Now we are working on LOD3 which is to texture the boxes using our drone and AI program.
  • The digitized detailed plans are submitted and are the basis for the digital twin for community building. For us, the digital detailed plans are not the end product, but are further developed into three-dimensional detailed plans to, among other things, offer citizens automated building permits in the future.

Drones, AR and VR equipment are used internally and externally in civil dialogues.

The 3D model will be a digital twin

"The vision of the digital twin is to create, test and build everything in a virtual environment. Only when we are satisfied with the result, that it lives up to our goals, we will build the physical environment. Via sensors, the built environment will then be linked back to the digital twin so that all the information about it can be found there as a basis for further improvements "

In order for a digital twin to truly benefit from community planning and contribute to new smart and socially sustainable solutions, it needs to be filled with relevant and current data that is continuously updated and can be used for analysis and simulations. The ambition is to combine different technologies such as IoT, GIS and BIM to develop and further develop them in real time.

Trees, lampposts, parking lots, bathing buoys, information about World Heritage buildings and other cultural-historical buildings, BIM models etc. are entered with information / data about the objects.

Connected bins

  • Connected objects such as dustbins, parking spaces, lighting poles, public transport and company cars are connected to the model.
  • Temperature monitoring of walkways to monitor temperature and alarm when slippery control is needed.
  • Monitoring of electrical cabinets to directly detect power outages and disturbances in the network.
  • Measurement of water temperature at several bathing sites and water level under bridges.
  • Measurement of air quality in office environments
  • Monitoring of Archipelago traffic's boats to detect leakage and temperature changes.
  • Welfare technology projects are being carried out where a number of apartments have been digitized to create security through connected technology.
  • IoT points for noise measurement, wind, water, sewage etc.
  • Movement patterns via mobile data.
  • Parametric design in urban planning

The purpose of creating a real-time twin?

  1. The municipality - a tool to get a current and overall visual overall picture of the city and the countryside right now, past and future. An instrument for being able to make simulations and analyzes of different future scenarios and enable streamlining of the municipality's decision-making processes. Where all data and GIS data are in one place to then further distribute fast and secure analyzes for decisions to competent officials, politicians and authorities, which becomes significantly more cost- and time-efficient.

    • Citizens, companies, academies, etc. - Gets and provides a clear, transparent and fast democratic citizen dialogue and service in both directions. Where the exchange of data in society is created and new innovations and services can be formed.

    • Developing the whole society - Exchanging information between cities and countries to develop aids using AI. Patterns between cities and countries are found to learn and improve and not repeat mistakes over and over again. "Self-healing cities"!

On the way to real-time twins.

Parametrisk / Generativ design - André Agi

Our next step is to start using more parametric design in detailed plans, to calculate the best proposal from both the hard and soft world from exploitation figures with shadow and noise investigations to bring in social factors such as security and the child perspective.

We also need to organize, structure data and test run open data and Big data.

In parallel, AI, AR, VR, IoT, mobile data and more e-services are further developed to have an even more efficient planning process and to be able to use the digital twin as a "crash test doll" before the detailed plans are approved.

Imagine when the building permit becomes an automatic process, that this can be reversed until the "builder's" proposal is translated into an automatic detailed plan - of course with a hand-laying at the beginning until AI has learned how to build a good built environment!

This would provide a faster work process and safer democratic decisions.

But to get there, you need more knowledge, computer power and money.
