This paper empirically studies the importance of managing design changes in dealing with
time delay and cost overruns in construction projects. The main objective of this paper is to …

The complexity and uncertainties associated with construction projects mean that contracts
invariably provide sufficient flexibility for changes in design as the work proceeds. However …

During many construction projects frequent changes often result in time delays, cost
overruns, quality defects and other negative impacts. In recent years, many researchers …

Cost is one of the major considerations throughout the project management life cycle and
can be regarded as one of the most important parameters of a project and the driving force …

Isolation of design phase from construction has made the design changes inevitable in
construction projects. Extensive literature appraisal has acknowledged the detrimental effect …

Rework is positively linked with increased safety risks. As a precursor to decreased rework
and enhanced safety performance, this study appraised the correlative causes of rework and …

Productivity, defined as output per input, is a key performance indicator. Construction is one
of the least productive industries, and in this paper we explore how productivity …

Changes almost always occur on construction projects. Among other things, they can hurt
labor productivity. The relationship between change and labor productivity, though …

The purpose of this study is to investigate the mutual interactions between the causes of
design changes using Interpretive Structural Modeling (ISM) and to classify the causes using …

Changes are the main causes of delays and cost overruns in construction projects. Various
change management systems have been developed to minimize the impacts of changes …
