    BIM with Location

    Manage your project in its real context and surroundings

    xD Twin manages project models in their real world locations. You can easily drag and drop models into their real locations. Global backgrounds like maps, aerial photos, terrain and buildings help you localize your project elements easier. 

    You can also integrate projects with city models which gives you the best digital understanding of how projects fit into their real surroundings. 

    City + Buildings + Infra 

    Manage all disciplines as one digital twin

    xD Twin is a unique digital twin solution because it integrates all project disciplines, phases and detail levels into one digital twin. With xD Twin you can manage projects that have city plans, buildings, infrastructure and transportation integrated into city models. Data can be from different project phases, detail levels and data formats.

    Multi-project digital twins

    Project to project coordination is becoming increasingly important

    Projects can share information to other projects which will help project to project coordination. You can for example share pipe networks from a street project to a building project, or you can combine one master digital twin from all sub-projects in a  large area construction project .

    You can even combine all city projects into one future digital twin of a city and manage whole city development as one digital twin.

    BIM + GIS

    Future of information management is BIM + GIS

    xD Twin combines BIM and GIS into one easily manageable information model. It is rare that a project would only manage BIM data. There is a lot of data needed from GIS too, for example land usage, land ownership, property limits, nature protection, noise, air quality and many kinds of location based data and gis analysis. You can overlay this data to your project from multiple data sources with open WMS / WFS interfaces.

    BIM + Time (4D)

    Future of digital twins is 4D

    Every project needs a schedule. xD Twin allows you to present your project schedule as a 4D simulation. This is useful for example to present how the city or city area plan will develop over time. You can also schedule design models and Sketch objects. This way you can make 4D simulations of the construction sites. 

    Sketch your ideas

    Successful project is based on good ideas

    xD Twin has simple and easy to use sketch tools that allows you to sketch your ideas directly to the models. This way you can instantly test for example how different size building volumes fit into the city scape. Or you can sketch construction site arrangements on top ot design models and site drone models. 

    Publish and collect feedback

    Successful projects are based on open citizen collaboration

    xD Twin allows you to publish your project as a public project which can be viewed by anyone without logins. This shortens the time from design to presentations and public hearings and improves transparency and collaboration with the citizens. 

    xD Twin has a location based feedback tool where project can customize what kind of feedback is collected and from what parts of the project. This kind of facilitated feedback can be much more valuable to the project than traditional generic feedback. 

    See your project On-Site

    Project data can be viewed on-site with GPS positioning and compass orientation. Users can automatically zoom into their location and view data around them from the birds eye view in correct orientation.

    With AR (Augmented Reality) users can view project data through the mobile device's display combined with the camera image.

    • Save time and access data on-site with automatic zoom

    • Save time and access data with simple point and click operation

    Everyone on-site can use this without any extra costs. This works with any smart device and doesn't need any external hardware or services.

    Easy and Fast

    • As easy to use as map apps: Everyone can learn and get benefits instantly. xD Twin works in ways most users are already used to.

    • Projects open in seconds:  Access information instantly without waiting. Intelligent web3d streaming loads only what you need. This allows accessing almost unlimited size datasets.

    • Anywhere, anytime, any device: xD Twin is completely browser based and mobile friendly. Everyone can access information anywhere and anytime even with slow connections. No need to worry about app installations, privacy settings or updates. xD Twin is always up to date.

    Data Fusion

    Combine multiple data sources and formats in a CDE (Common Data Environment) to manage all aspects of the project as one digital twin.

    • Global maps, aerial photos, terrain and buildings

    • City models (Mesh and CityGML)

    • GIS data (WMS, WFS)

    • City planning models

    • Visualization models

    • Building BIM models: IFC

    • Infrastructure BIM models: IFC, Inframodel

    • Construction production data

    • Survey data (point clouds, lines, points)

    • Drone photogrammetry models

    • As-built data

    Digital Twin of Data and Processes

    Projects have many processes and processes have a lot of data to manage, not to forget people who have jobs to be done. xD Twin goal is to link these into a production system that can simulate, optimize, manage and track these processes. This will result in improved production speed and cost savings. xD Twin manages this:

    • Planning, design and construction data fusion

    • Analyze and measure data to ensure quality and constructability

    • Communication and collaboration is done inside the digital twin

    • Tasks risks, ideas, notes, issues are managed inside the digital twin

    • Data is linked to tasks and workflows so they are easily available

    • Automatic reports and real-time project dashboards

    • Project can be virtually built with 4D scheduling

    • Design and as-builts can be combined for QA analysis

    • Drone and laser scan surveys create situational awareness to the site

    • Fast access to data anywhere, anytime with any device

    • Data is easily accessible on-site with GPS and AR

    Virtual Construction

    xD Twin goal is to make a digital twin of business processes. This means not only the digital twin of data, but also the digital twin of tasks and workflows. xD Twin links these together so that projects can be virtually constructed before actual construction. Virtual construction costs are only 0.001% of real construction costs. This allows a lot of optimization and improvements virtually before actual construction. This results in cost and time savings, sustainability and better functioning solutions.
