Abstract
Design changes are common in building projects. Design changes are almost inevitable during the lifecycle of a project; however, design change can be minor or major according to the result. Identifying the source and impact of each design change in the construction lifecycle could help manage all of the design changes associated with a project. Furthermore, such management of changes could help to define preventive measures and actions. A complete survey was conducted using interviews and questionnaires with professionals in three main groups involved in reinforced concrete building projects; all of the sources, causes and impacts were defined by their level of importance. Corrective and preventive actions were measured to avoid as many design changes as possible in this research. The results of this research encourage the implementation of preventive actions by the professionals involved in low-rise reinforced concrete building projects

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
