In Spain, the high levels of inexperienced workers and the long chains of subcontracting contribute to the poor quality of dwellings.
Althoughthe
Ley reguladora de la subcontratación en el Sector de la Construcción
(subcontracting law) has established quality measures, the
number of customer complaints is still increasing. In this paper, a total of 2,351 posthandover defects derived from four Spanish builders and
seven residential developments are classi
fi
ed according to their source and origin. The research reveals that the most common defects identi
fi
ed
by customers at posthandover were derived from bad workmanship and were related to construction errors and omissions. Typical defects were
foundtoincludeincorrectinstallation,appearancedefects,andmissinganitemortaskmainlyrelatedto

defects were caused by poor design because they are mainly detected and resolved during construction or become apparent after some years of
use. This study demonstrates the negative impact of redoing defective work during the
fi
nal stages of construction and provides knowledge to
de
fi
ne measures to improve the quality of the
fi
nished buildings, such as understanding customer expectations and preferences, training
programs for workers, specialization of subcontractors, and tightening external controls prior to handover. |
