The model covers an area of 34.8km2 within Oslo’s central city area. The Agency for Planning and Building Services of the City of Oslo completed a 3D printed city model of Oslo on October 1 last year. It is Norway’s largest entirely 3D printed model, if not the largest in northern Europe.
The model is located in the lobby of the agency and offers visitors and employees more than just a visual experience – it acts as an interactive information platform as well as a decision-making tool that can be used in aiding urban planning.
3D modelling is not exactly new to the City of Oslo. A 3D model had been on display at the agency for about a decade before this new city model was produced. But the previous version had one main challenge – it was expensive and difficult to update. So when the agency decided in 2010 to create a new 3D city model, it knew the solution would have to be innovative.
Research into possible methods of creating a new model began in 2010, based on experience of updating the old model. By 2012, the project team had decided on 3D printing technology as the solution. This was then followed by a period of development, once an A3 3D Printer had been bought, as the agency had neither all the required expertise nor many examples or reference projects to learn from, especially in Scandinavia. The creation of the model began in earnest in January 2014, using eight team members in all. Building the City Model directly from a 2D basemap combined with printing in small block parts enables it to be updated almost the day after an urban project has been added to the basemap. This means that what you see on the model is what currently exists in reality, making it a powerful city planning tool.
Indeed, planners, politicians, developers and the public get a different perspective of the city in 3D instead of the traditional 2D map. The benefits of a 3D model are very useful in the planning process since the important task of providing the different stakeholders with spatial information becomes easier. The agency chose to include approved future development projects and important areas of the city that are already under development. These selected areas are highlighted with a distinct colour and include both buildings and large urban areas.
The model is divided into 360 blocks of approximately A3 DIN size. Each block can be picked up and replaced when necessary. This too, contributes to the speediness of updating the model, since only a small section of the model needs to be reprinted. It is 7.6m x 4.5m. read the original article in PDF.
