The spatial parts of your project can be defined and specified in the tree Spaces & locations.
In building projects, this tree is usually the most important part of the project as spaces typically carry most of the project’s requirements (on indoor climate, elements that need to placed etc.). Basically, you are making a room book with room data sheets.
In infrastructure projects, this tree tends to be less extensive but still highly relevant for defining the locational and geometrical aspects of the project (e.g. road segments, traffic lanes, cable corridors).
Below we’ll explain the different kinds of objects that can be used in this tree.
Different types of objects
When creating this tree, you will be able to use different types of objects to help structure your tree:
Location
This object represents the specific site, address or plot where a building or infrastructural object is located or must be realised. The object can be used to capture, for example, zoning requirements.
Connection
This objects represents an infrastructural connection between two points. This can be a high-level object such as a road connection or rail track between two locations, but also a very specific connection such as a cable corridor or a street.
Segment
A segment is a specific functional or spatial part of an connection. E.g. a traffic lane or tunnel segment. Typically segments have a concrete width or length.
Civil structure
This object is the spatial and/or functional representation of a built structure other than a building. E.g. a pump station, offshore platform or water treatment facility. Just like a building (see below) it can be further subdivided into spaces and groups of spaces.
Building
This object can be used as a starting point for a breakdown of all the spaces that should be located in the same building.
Group of Spaces
This object can be used to indicate larger areas or parts of a building which can then be broken down or subdivided into individual spaces. Examples of grouping areas include departments in hospitals, the entrance area of a public building or a conference center at a campus.
Spaces
This object is the most basic unit of the project’s space tree. They are the actual volumes where user activities take place. Spaces are the most important objects of the model as they carry most of the requirements. They can have a size, capacity, particular room items, acoustic qualities, and so on.
Outdoor Spaces
This object is essentially the same as the regular spaces above, but specifically labelled as being outdoors. Examples of outdoor spaces are parking spaces, playgrounds, and bicycle storage. Linear elements, such as foot paths or roads can also be considered outdoor spaces.
Creating objects
Go to the Spaces & locations tree and click on the at the top of the page. This will allow you to create your first spatial object. A window will pop up offering you four options to choose from (as discussed above). Once you click on one of the options and a name for the object.

When creating and organizing the spaces for your project, it is good to know that you can easily move objects around, search for objects, rename them, delete them if necessary, and you can easily clone (copy/paste) them if you want to use the same type of space elsewhere in your break-down.
This can all be done by using the presented buttons in your screen. For a general explanation about these buttons, click here.
Structure for building projects
Typically, a spatial break-down for a building project is structured as follows:
- You often start with a building object as the top object of your tree.
- Next, there are likely to be one or two levels groups of spaces which can be used to cluster spaces of a particular kind (e.g. meeting spaces), or for a particular user (e.g. department A or B).
- And, ultimately, at the lowest level there will be spaces with all the specific requirements.
- Outdoor spaces are often located on the same level as the building, unless it concerns outdoor spaces that are part of the building (e.g. roof terrace).
Making such a break-down is also referred to as a processes of decomposition, in which you start with a top object (e.g. building), which is step-by-step, divides up until smaller parts. These parts become more concrete, more detailed and more ‘material’ as you work you way down the decomposition structure.
See for a simple example below.

Structure for infrastructure projects
There are obviously many different kinds of infrastructure projects, but if we focus on ‘connections’ (a road, a rail link, tunnel, …), you spatial ‘tree’ will typically look something like this:
- You probably start with a location object as the top object, indicating the area where the connection has to be realized and/or to indicate the actual locations that have to be connected.
- Next, there is the connection itself , which may be subdivided into a smaller parts and/or be linked to other connections (e.g. an existing road).
- At the lowest level of the connection’s spatial subdivision will be specific segments which typically carry concrete geometric requirements such as width or length, and can have relations to spatial elements such as traffic lights or road markings.
- Civil structures may be added to indicate the location or geometry of building-like entities such as pump stations or water reservoirs.
