A working drawing (also called execution planning) is the fifth phase of a total of nine work stages of HOAI. Working drawings contain all the information required for the construction or reconstruction of a building.
Execution planning includes further development of an approved design under detailed technical aspects. As a basis for the execution solution, all calculations and dimensioning must be performed.
For a comprehensible display of the results, table overviews are provided. Examples of this include door lists to describe all the required properties of doors, and valve lists in the field of plumbing and heating planning, for coordinating the properties with the building automation.
