This part of ISO 4463 deals with the progressive stages of setting-out work in building construction, i.e. acquisition of information establishing the primary System, setting-out the secondary System, vertical transfer of Points in the secondary
System to other levels, and setting-out the Position Points and the establishment and transfer of levels (bench marks). In addition it gives values of permitted deviations and guidance on independent check measurements (quality control) using instruments and methods currently in common use at each Stage of the setting-out process.
