Qualitative and Quantitative Analyses on Project Deficiencies in Flat-Roof Design in Extremadura, Spain

Abstract
The present paper reports on the analysis performed over a set of 44 final designs projected in the period 2000 to 2007, and is aimed at performing a quantitative and qualitative analysis on the prevalence of project deficiencies in flat roofs in construction building projects. The methodology is based on the study of a set of control parameters to point out the most frequent deficiencies in flat-roof designs. Out of the total number of sample projects, only eight (18.18% of total number of projects) were categorized as high-quality projects, while 17 (38.63%) and 19 (43.18%) were finally regarded as intermediate and low-quality, respectively. The use of accurate methodologies at former project stages to identify potential failures or construction deficiencies in advance is a successful predictive strategy, which directly enhances infrastructure sustainability. It provided they might prevent between 70 and 80% of the standard pathologies addressed for flat roofs, and might moreover achieve annual saving rates as high as during building use.
