Indicators for Building Process without Final Defects -: methodology and theoretical foundation

This article introduces the preliminary data analysis, as well as the underlying theories and methods for identifying the indicators for building process without final defects. Since 2004, the Benchmark Centre for the Danish Construction Sector (BEC) has collected information about legal defects in connection with Danish construction enterprises that have been handed over. The project aims to utilise the knowledge potential available in BEC´s database in order to locate key performance indicators of construction failures and defects. The empirical data from BEC is applied in a more academic context than has been the case until now. The idea is to survey which indicators differentiate good construction and processes of construction from bad ones. The method is a retrospective analysis, which is based on data on the handing over. The data used has been partly that which BEC has already collected and partly additional focused data collected through interviews and electronic questionnaires directed to developers, designers and contractors. The first results from the data collection will be available in spring 2011 and will be able to indicate the differences between construction without or with only a few defects and construction that is handed over with many and serious defects.
