Hwang, B G and Yang, S (2014) Rework and schedule performance: A profile of incidence, impact, causes and solutions. Engineering, Construction and Architectural Management, 21(2), pp. 190-205. ISSN 0969-9988
Abstract
Purpose: Rework is a pervasive problem in the construction industry. While several studies have examined the relationship between rework and cost overruns, few have related rework to schedule performance impacts. As a result, the purpose of this paper is to assess rework in the construction industry and its impact on schedule performance. Additionally a discussion of the most probable causes for rework that affect schedule outcomes is presented, with some recommended solutions. Design/methodology/approach: To achieve the objectives of the study, a questionnaire was developed and the responses from 32 companies in Singapore were analyzed. Furthermore, face-toface interviews with six industry experts were conducted to get an in-depth understanding of the survey results. Findings: The findings of this study revealed that rework is a leading factor affecting schedule performance and its occurrence is relatively high in the construction industry, with a significant contribution to construction schedule growth. It also identified certain root causes, namely designrelated changes, poor design coordination and poor site management as factors that most negatively affect schedule performance. Originality/value: It is anticipated that once companies recognize the causes for rework and their impacts on schedule, they will develop strategies to manage and prevent rework, ultimately allowing the industry to improve on project delivery schedule performance. 0969-9988.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
