Abstract

A computer-implemented method for producing a data representation of a specific building, in particular in the form of a house instance building information model (house instance BIM), by using a processor. A set of house product configuration data and a configuration rule instruction are retrieved, a first configuration input is received, the first configuration input triggers (a) the application of the at least one configuration rule instruction to the set of house product configuration data by using a configuration program that is executed in the processor to instantiate a configured house instance structure (HIS) formed of a plurality of HIS elements, or (b) the retrieval of a pre-instantiated house instance structure (HIS) and the application of the at least one configuration rule instruction to the set of house product configuration data and to the pre-instantiated house instance structure by using a configuration program that is executed in the processor to produce a configured house instance structure (HIS) formed of a plurality of HIS elements. From a product BIM (PBIM) element data store (160) a plurality of PBIM elements are retrieved, each of which corresponds to a respective HIS element among the plurality of HIS elements. A BIM element instance is created for each retrieved PBIM element by applying to the retrieved PBIM element a parameter value or a relational property on the basis of information carried by the respective HIS element. A house instance BIM is formed by assembling the created BIM element instances.

Claims

1. A computer-implemented method for producing a data representation of a specific building, in particular in the form of a house instance building information model (100) (house instance BIM), by using a processor, which method comprises

[1] retrieving a set of house product configuration data (110);

[2] retrieving at least one configuration rule instruction (120);

[2.1] receiving a first configuration input,

characterized by

[3] responding to the first configuration input by

[3.1] applying the at least one configuration rule instruction (120) to the set of house product configuration data (110) by using a configuration program which is executed in the processor to [4.1] instantiate a configured house instance structure (HIS) (130) formed of a plurality of HIS elements (140);

or

[3.2] retrieving a pre-instantiated house instance structure (HIS) and applying the at least one configuration rule instruction (120) to the set of house product configuration data (110) and to the pre-instantiated house instance structure by using a configuration program that is executed in the processor to [4.2] produce a configured house instance structure (HIS) (130) formed of a plurality of HIS elements (140);

[5] retrieving from a (150) product BIM (PBIM) element data store (160) a plurality of PBIM elements (170), each of which corresponds to a respective HIS element among the plurality of HIS elements (140);

[6] creating a BIM element instance (180) for each retrieved PBIM element (170) by

[7] applying to the retrieved PBIM element (170) a parameter value (190) or a relational property (200) on the basis of information carried by the respective HIS element (140); and

[8] forming a house instance BIM (100) by [9] assembling the created BIM element instances (180).

2. A method according to claim 1, wherein the HIS structure (130) [10] is provided with information that determines a selection of PBIM elements (170) from the PBIM element data store (160).

3. A method according to claim 1, wherein the PBIM element (170) is arranged as a parametrized PBIM element (170) or a specific PBIM element (170).

4. A method according to claim 1, wherein at least one of the plurality of HIS elements (140) is a storey element, an axis element, cell element or an apartment element.

5. A method according to claim 1, wherein the BIM element instance (180) comprises geometric data which permits a visual presentation of the house instance BIM (100) that is formed.

6. A method according to claim 1, wherein applying the at least one configuration rule instruction (120) to the set of house product configuration data (110) comprises creating a HIS element with identification and location information which identifies and locates a respective PBIM element.

7. A method according to claim 6, wherein the identification and location information is provided by an entry in a reference work which holds identification and location information, as a result of executing one or more of the aforementioned rules, or as a result of a computation.

8. A method according to claim 1, wherein the retrieved PBIM element (170) is represented as a CAD model.

9. A method according to claim 8, wherein retrieving from a (150) product BIM (PBIM) element data store (160) a plurality of PBIM elements (170) is carried out by a CAD tool that is adapted to a CAD model.

10. A method according to claim 9, further comprising assigning through the use of the CAD tool a unique identifier to the CAD model which at any given time represents a retrieved PBIM element that is read into the CAD tool.

11. A method according to claim 1, wherein the parameter (190) comprises both a position determined by a set of coordinate values and a direction determined by a set of direction data.

12. A method according to claim 11, wherein the set of coordinate values is defined in a Cartesian coordinate system.

13. A method according to claim 1, wherein the HIS element is an object in an object structure or the like.
