Digital Twin is a digital replica of physical data, processes, systems and digital simulation of reality, which can be used for various purposes.

In order to create the Digital Twin we use Autodesk Revit together with Dynamo, empowering them with Python scripts for additional options and flexibility.

Autodesk Forge

One of the issues with Digital Twins is the fact that the power of Digital Twins stays trapped inside of original Revit model. Usually, only limited number of people have access to this original model, because they need to fulfill a number of requirements to be able to read data – they need to have installed and licensed version of Revit, a computer capable to work with such complex models, they need to know to use Revit software and to have access to Revit file and security privileges in order to use it.

So, to make a Digital Twin and its extensive data available to a large number of users, we have developed a Web application to make this simple and easily accessible.

Digital Twins - app development

The web application is based on a relatively new platform - Autodesk Forge. The building model was created in Revit, then converted to a Web acceptable form, using Autodesk Forge.

The rest of the development was done with some of the popular web development tools, such as JavaScript, jQuery, Bootstrap, Node, Node express…

With provided web application, users can access the Digital Twin from any modern internet browser - Google Chrome, Mozilla Firefox, Microsoft Edge. Our recommendation for the browser choice is Google Chrome.

Provided images are showing first Digital Twin in Serbia – shopping center “Sad Novi Bazaar”, created in cooperation with Matijevic company (owner of the building), from Novi Sad. More information about building and cooperation is available on our Digital Twins page.

The Digital Twin Web application is providing tools to access information about the object, to isolate parts of the object, walk through the model…

Digital twins Web app



TeamCAD engineers were involved in the creation and development of the first Digital Twin in Serbia. It was made for a well-known shopping center "SAD NOVI BAZAAR", located in the center of Novi Sad, in the pedestrian area. It is considered one of the go-to places for shopping, spread over 4 levels and 9.000 square meters of commercial real estate. Today, "SAD NOVI BAZAAR" Shopping mall is managed by Mat-real Estate, part of Matijevic company from Novi Sad.

What is „The Digital Twin“?

Before we describe challenges on a project and steps made to solve them, let us remind ourselves that "digital twin is an identical copy of the existing or designed building (or object) in digital format", as mentioned in the article „Digital Twins In The Construction Industry“.  Further in the article we can find out why they are used for: „Primarily, digital twins were used to estimate the cost of maintaining different components, systems, circuits, and buildings by making various simulations of phenomena and processes that would occur on existing objects using their digital format replicas.“

Project challenges

Some of the standard challenges when managing this type of objects were:

  • Providing energy efficiency of the object and lower AC costs
  • Having exact information about the quantity and locations of the equipment (AC systems elements, fire protection systems, electrical installations...)
  • Information about the warranties, service intervals, life expectancy for the above-mentioned equipment.
  • Real-time information about the real estate renting possibilities and vacancies for potential commercial clients.
  • In case that the clients adapt rented space, they need to promptly access information about the movable and immovable walls.
  • In case of any changes in the building or inside the building, accordingly entering new data in the 3D model and technical documentation.

The additional challenge was the fact that the original building was designed by an architect Milan Mihelič in the now distant 1972, so there was no existing digital documentation.

Solution for the problem

As TeamCAD and Matijević companies are successfully cooperating for years, while TeamCAD`s Novi Sad branch office is situated in the business part of the "SAD NOVI BAZAAR" Shopping mall, we have decided to continue our partnership on this project as well.

We have created the first phase of the building`s Digital Twin model and used the latest technologies, which enable the user to view and move through the Digital Twin object, using just an internet browser. There is no need whatsoever to install any type of 3D software. Technologies and software used for completing this project, amongst others, were: Autodesk Inventor, Autodesk Forge, Autodesk Vault.
