receiving a plurality of representative drawings that comprise a portion of a building, the plurality of representative drawings including Computer-Aided Design (CAD) drawings;

extracting a number of layers from the CAD drawings, one of the extracted layers including a Heating Ventilating and Air Conditioning (HVAC) related layer;

extracting CAD data from the CAD drawings;

extracting equipment parameters from the CAD drawings;

fusing the extracted CAD data and the extracted equipment parameters from the CAD drawings into a Construction Operations Building Information Exchange (COBIE) table for at least the portion of the building;

assigning the extracted number of layers into a number of categories; and

merging the categories together to form the BIM model to correspond with the COBIE table.

2. The computer-aided method of claim 1 , wherein one of the number of categories comprises a floor plan category.

3. The computer-aided method of claim 1 , wherein one of the number of layers comprises one of a door layer, a wall layer, a room tag layer or a stair layer.

4. The computer-aided method of claim 1 , wherein one of the number of layers comprises one of a diffuser layer, a Variable Air Volume (VAV) layer or a ductwork layer.

5. The computer-aided method of claim 1 , wherein the extracted number of layers correspond to a single floor of the building.

6. The computer-aided method of claim 1 , wherein the extracted number of layers correspond to a plurality of different floors of the building.

7. The computer-aided method of claim 1 , wherein extracting a number of layers from the CAD drawings comprises extracting a single layer type or a single object at a time.

8. A non-transitory computer readable medium, comprising instructions to:

receive a plurality of representative drawings that comprise at least a portion of a building, the plurality of representative drawings including Computer-Aided Design (CAD) drawings;

extract CAD data from the CAD drawings;

extract equipment parameters from the CAD drawings;

fuse the extracted CAD data and the extracted equipment parameters from the CAD drawings into a Construction Operations Building Information Exchange (COBIE) table for at least the portion of the building; and

form a Building Information Model (BIM) that correspond with the COBIE table.

9. The non-transitory computer readable medium of claim 8 , further comprises instructions to:

extract a number of layers from the CAD drawings, one of the extracted layers including a Heating Ventilating and Air Conditioning (HVAC) related layer;

categorize the extracted number of layers into a number of categories; and

merge the categories together to form the Building Information Model (BIM) that correspond with the COBIE table.

10. The non-transitory computer readable medium of claim 8 , wherein one of the number of layers comprises one of a door layer, a wall layer, a room tag layer or a stair layer.

11. The non-transitory computer readable medium of claim 8 , wherein one of the number of layers comprises one of a diffuser layer, a Variable Air Volume (VAV) layer or a ductwork layer.

12. The non-transitory computer readable medium of claim 11 , wherein extracting a number of layers from the Computer-Aided Drawing (CAD) drawings comprises extracting a single layer type or a single object at a time.

13. The non-transitory computer readable The medium of claim 8 , further comprising instructions to identify a number of objects including: spaces, doors, stairs, and elevators.

14. The non-transitory computer readable medium of claim 13 , wherein the number of objects includes Heating Ventilating and Air conditioning (HVAC) data including: diffuser data, Variable Air Volume (VAV) data, Air Handling Unit (AHU) data, and ductwork data.

15. A system for building a Building Information Model (BIM) for at least part of a building from a plurality of Computer-Aided Design (CAD) drawings, comprising:

a computer memory; and

a computer processor configured to execute executable instructions stored in the computer memory to:

receive a plurality of CAD drawings that each comprise a portion of a building with a corresponding number of objects;

extract a number of objects from each of the plurality of CAD drawings including object data and object parameters;

determine a boundary of each of the plurality of CAD drawings;

determine a location of the number of objects within the building;

stitch the plurality of CAD drawings into a BIM representation of the building based on the boundary and the location of the number of extracted objects within the building; and

associate extracted object data and extracted object parameters with the number of extracted objects, the number of extracted objects including Heating Ventilating and Air Conditioning (HVAC) objects; and

creating a Construction Operations Building Information Exchange (COBIE) table for at least the portion of the building based at least in part on the extracted object data and the extracted object parameters.

16. The system of claim 15 , wherein the object data from the extracted objects includes one or more of: a corresponding name, a corresponding object number, a corresponding serial number, and object usage data.

17. The system of claim 15 , wherein the instructions to associate extracted object data and extracted object parameters includes instructions to bind the object data and object parameters to a corresponding object.

18. The system of claim 15 , further comprising instructions to align a CAD drawing from the plurality of CAD drawings that represents a bottom floor of the building with at least one other CAD drawing from the plurality of CAD drawings.

19. The system of claim 15 , wherein the number of extracted objects includes a particular layer of devices that interact to provide a system for the building.
