  The Pixel Detector of the ATLAS experiment has shown excellent performance
during the whole Run-1 of LHC. Taking advantage of the long shutdown, the
detector was extracted from the experiment and brought to surface, to equip it
with new service quarter panels, to repair modules and to ease installation of
a new innermost layer, the Insertable B-Layer (IBL). An overview of the
operational experience, the refurbishing of the Pixel Detector and of the IBL
project as well as the experience in its construction, integration and
commissioning are described.
