E-mail: caldas@ (Accepted 23 September 2008) Introduction Construction projects often experience cost and schedule overruns and rework is a significant factor that directly contributes to these overruns. Research by the Construction Industry Institute (CII) reveals that direct costs caused by rework average 5% of total construction costs (CII 200511). Considering that the U.S. construction industry expended $1,502 billion in 2004 for total installed costs (Bureau of Economic Analysis 20065), 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 198623; CII 19897; Davis et al. 198912; Burati et al. 19924; Love et al. 1999a20, b21; Love 2002b16; Fayek et al. 200313; Love and Edwards 200417) 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.
