Working height describes the level at which the intended task takes place or the surface needs to be reached.
What does this mean for your project?
The term is sometimes confused with the height of the supporting platform. For an enquiry, identify the actual feature requiring access, such as a cornice or window head. The contractor performing the work can explain the position needed to carry out that task.
A standard difference between platform height and working height does not suit every activity. Tools, movements and reach vary with the method. Avoid prescribing a self-selected subtraction as a fixed technical requirement without assessment of the actual work and arrangement.
The planner uses an overall elevation height to illustrate the project brief. Final platform levels and access provisions do not follow automatically from that input. Record unusual work points and uncertainty in the message so the provider can consider them.

Does working height mean the level of my feet?
No; that is normally described as platform height. If uncertain, name both the target feature and the intended activity.
Does the planner calculate my reach?
No. It records overall dimensions without assessing a suitable or safe working position.
