Using 4D simulation to support decision making

If you manage a business unit which impacts a city over time, chances are you are constantly confronted with the unexpected, the unpredictable.

Cities experience variations in demographics, land use, urban development. Cross the street, and you're faced with a new set of dynamics. Behaviour patterns, new projects, competition,  the domino effect of interactions are exponentially increasing the pace at which our environments are changing.

Decision makers can feel blindsided when it comes to looking into the future. Long term vision and planning is critical to your business, but current practices or technology don't allow you to master that complexity and its constant evolution.

A digital replica for perspective planning

Our platform consists in a web-based 3D visualisation engine fuelled by complex systems modeling capable of computing the impact of affecting factors. Through these models we provide our clients with long term prediction capabilities, in other words the 4th dimension of our solution.

ForCity offers a suite of sector-specific applications which allow users to play out infinite amounts of scenarios over a 20 to 30 year time frame. Our applications provide unparalleled insight into potential development and strategic support for smart, collaborative and sustainable planning.


Widen your range of action and simplify decision making

Add external yet critical factors to your model

By applying this systemic approach to simulation over time we go beyond typical projection methods in order to deliver much more finer tuned scenarios. This allows our users to detect both strong and weak signals early in the decision making process.

Each ForCity application allows the platform user to run simulations in real time, anywhere, by accessing a non-technical, user-friendly interface. Thanks to its 2D-3D visualization engine and ease of use, the platform enables our users to facilitate communication, greatly reducing risk and unknowns, be it for master planning or committing to an investment.
