the modifications introduced during the site works have been already implemented in the AutoCAD soft files. That mean that the AutoCAD layer of that installation have been modified according to the reality, but doesn´t mean that the drawing have been printed into pdf soft file: the acrobat file will be prepared only once for the handover date (still not set), but cannot be done before because another modifications in another pending drawings can indirect affect to the main pattern (and consequently, to the drawing).
