| # CivilSpatial | ||
|
|
||
| This schema contains the main classes to capture the Spatial Structure of Site projects. | ||
|
|
||
| NOTE: Currently under development. This schema should not be used for production workflows. Data created using this schema is not supported and may not be upgradable. | ||
|
|
||
| The following class diagram depicts the main classes in the CivilSpatial schema that extend the _Site_-related concepts from the `SpatialComposition` schema. | ||
|

|
|
||
| The following class diagram depicts the main classes in the CivilSpatial schema that extend the _Space_-related concepts from the `SpatialComposition` schema. | ||
|
|
||
|  | ||
|
|
||
| The following instance diagram depicts a simplified spatial hierarchy of a sample of a "Shopping Plaza", involving not only concepts defined in the `CivilSpatial` schema, but also the `BuildingSpatial` and `RoadSpatial` schemas - all of which are based on common rules and patterns defined in the `SpatialComposition` schema. | ||
|
|
||
|  | ||
|
|
||
| ## Entity Classes | ||
|
|
||
| ### Site | ||
|
|
||
| `Site`s must be contained in `SpatialLocationModel`s or `PhysicalModel`s. | ||
|
|
||
| ### ParkingArea | ||
|
|
||
| `ParkingArea`s must be contained in `SpatialLocationModel`s or `PhysicalModel`s. | ||
|
|
||
| Equivalent to [IfcSpace](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcSpace.htm) with a PredefinedType attribute set to [IfcSpaceTypeEnum.PARKING](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcSpaceTypeEnum.htm). | ||
|
|
||
| ### ParkingIsland | ||
|
|
||
| Instances of `ParkingIsland` are typically aggregated by instances of `ParkingArea` by using the `spcomp:SpatialStructureElementAggregatesElements` relationship. | ||
|
|
||
| `ParkingIsland`s must be contained in `SpatialLocationModel`s or `PhysicalModel`s. | ||
|
|
||
| ### ParkingRow | ||
|
|
||
| The number of Parking-spaces modeled in a single instance of `ParkingRow` is captured by its `ParkingSpaceCount` property. | ||
|
|
||
| `ParkingRow`s must be contained in `SpatialLocationModel`s or `PhysicalModel`s. | ||
|
|
||
| ### PondArea | ||
|
|
||
| Uses of permanent `PondArea`s include: to manage stormwater runoff, for protection against flooding, for erosion control, and to serve as an artificial wetland and improve the water quality in adjacent bodies of water. | ||
|
|
||
| When needed, a `PondArea` may aggregate smaller areas within their boundary, modeled as instances of `GenericArea`. | ||
|
|
||
| `PondArea`s must be contained in `SpatialLocationModel`s or `PhysicalModel`s. | ||
|
|
||
| ### Sidewalk | ||
|
|
||
| A `Sidewalk` instance may be aggregated by a `RoadwayPlateau` when defined as part of a `rdsp:Road`, or may be defined parallel to other `spcomp:Facility` instances. | ||
|
|
||
| When defined as part of a `rdsp:Road`, a sidewalk may accommodate moderate changes in grade (elevation) and is normally separated from the vehicular section by a curb. There may be a central reserve between the sidewalk and traffic lanes. | ||
|
|
||
| `Sidewalk`s must be contained in `SpatialLocationModel`s or `PhysicalModel`s and can be linearly located, typically along an *Alignment*. An instance of `Sidewalk` typically holds the `bis:PhysicalElement`s (e.g. *Course*s) comprising its *pavement* structure. | ||
|
|
||
| Equivalent to [IfcFacilityPart](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcFacilityPart.htm) with its PredefinedType attribute set to [IfcRoadPartTypeEnum.SIDEWALK](https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcRoadPartTypeEnum.htm). | ||
|
|
||
| ### GenericArea | ||
|
|
||
| `GenericArea`s must be contained in `SpatialLocationModel`s or `PhysicalModel`s. | ||
|
|
||
| ### SiteType | ||
|
|
||
| Instances of `SiteType` provide an additional classification that can be applied to `Site`s. | ||
|
|
||
| ### ParkingAreaType | ||
|
|
||
| Instances of `ParkingAreaType` provide an additional classification that can be applied to `ParkingArea`s. | ||
|
|
||
| ### ParkingIslandType | ||
|
|
||
| Instances of `ParkingIslandType` provide an additional classification that can be applied to `ParkingIsland`s. | ||
|
|
||
| ### ParkingRowType | ||
|
|
||
| Instances of `ParkingRowType` provide an additional classification that can be applied to `ParkingRow`s. | ||
|
|
||
| ### PondAreaType | ||
|
|
||
| Instances of `PondAreaType` provide an additional classification that can be applied to `PondArea`s. | ||
|
|
||
| ### SidewalkType | ||
|
|
||
| Instances of `SidewalkType` provide an additional classification that can be applied to `Sidewalk`s. | ||
|
|
||
| ### GenericAreaType | ||
|
|
||
| Instances of `GenericAreaType` provide an additional classification that can be applied to `GenericArea`s. |
