Generally, measured building surveys comprise an external survey at a scale of 1:100 to 1:500, a set of floor plans (which may also include reflected ceiling detail and a roof plan) at 1:50 or 1:100, and sections through the building which might include elevational detail. If the output is principally to a CAD system the scale of the output is effectively a function of the zoom factor in use. In this case the client specifies a "target" scale of say 1:50 which determines the required accuracy, level of detail and text sizes. The drawing however, is produced at a convenient scale so that the whole floor or facade fits onto a single sheet, with text, detail, and symbols scaled down such that, when enlarged to the target scale, everything appears at the specified size. This avoids the unnecessary production of large numbers of drawings, but gives the client the ability to plot out all or part of the drawing as required. The level of detail is specified by the client, and usually ranges from structural outline only, through to full detail of windows, doors, sanitary fittings and services.
