Key Points. Rework factors are categorized into four broad categories: project, human, organizational, and complexity. Rework impacts cost, schedule, and, importantly, morale and trust. Strategies exist to reduce the potential for required rework. Forty-eight control points are suggested.
Rework costs have been found to range from 5% to 20% of the contract value in construction and engineering projects, and changes in the scope of the design account for as much as 50% of the rework that occurs (Barber et al., 2000; Love and Edwards, 2004).
Rework is defined as work measures that have to be completed more than once. Burati J.L. et al. (1992) described rework as a “non-conformance;” Peter E.D. Love1 characterized rework as the “unnecessary process of redoing a work activity that was incorrectly carried out the first time.”.
Aug 25, 2021 · Rework in construction is inevitable. It has a direct impact on the cost and the time of the project. Therefore, finding the factors that lead to rework can help control the extra cost and time as well as preventing from design problems among architects, construction engineers, contractors and users.
Jan 3, 2020 · Simpeh (2012) studied the causes of the rework in construction projects in South Africa. He identified 43 causes of rework and categorized them into four groups related to client, design,...
The objective of this paper is to: Categorize rework factors into four broad categories – project, human, organizational and complexity. Identify rework impacts not just on cost and schedule but importantly morale and trust. Recognize that strategies exist to reduce the potential for required rework.
Institute database, this paper assesses the impacts of rework on construction cost performance for projects in various categories. In addition, it identifies the sources of this rework, permitting further analyses and the development of rework reduction initiatives.
