- Abstract
- Overtime in construction is usually defined as work performed over 40 hours per week, or in some instances, more than eight hours in one day. The construction industry has attempted to minimize scheduled overtime on most projects because it significantly increases the cost of construction. However, if an owner/contractor has to recover lost time or accelerates construction for any other reason, three basic alternatives exist: increase manpower, add shiftwork, or schedule overtime. Unfortunately, past studies generally have been inconclusive in qualntifying the effect these options have on productivity. For the purposes of this study, productivity is defined as output over input (quantities installed per work hour). The purpose of this report is to summarize to date the CII Overtime and Shiftwork Study. Background information on previous overtime studies is included, and the CII data collection and data processing methodologies are discussed. A summarization of data collected by CII researchers is presented.
