Research by the Construction Industry Institute (CII) reveals that direct costs caused by rework average 5% of total construction costs (CII 2005 11). Considering that the U.S. construction industry expended $1,502 billion in 2004 for total installed costs (Bureau of Economic Analysis 2006 5), almost $75 billion was wasted on direct costs caused by rework in that year alone. Therefore, rework must be considered a significant factor affecting cost performance in the construction industry. Several research efforts (O’Conner and Tucker 1986 23; CII 1989 7; Davis et al. 1989 12; Burati et al. 1992 4; Love et al. 1999a 20, b 21; Love 2002b 16; Fayek et al. 2003 13; Love and Edwards 2004 17) have attempted to identify and classify the root causes of rework, and to quantify its overall extent. Employing the metric, total field rework factor, and the classification of rework sources developed by CII, this paper assesses the direct impacts of rework on construction cost performance using data from 359 actual projects. More specifically, the objectives of the research described in this paper were: (1) to identify the impacts of rework on construction cost performance for various cha
