Abstract
In the quest to shorten project delivery time, construction professionals have the option of overlapping design and construction activities. Although time savings can be achieved by overlapping, conducting design and construction operations in a nonnatural sequence can carry significant risks. To mitigate these risks and make more appropriate overlapping decisions, concurrent engineering concepts can be used to classify upstream design activities in terms of design evolution and downstream construction activities in terms of sensitivity to upstream design changes. The focus of this work is to determine the factors that contribute to the sensitivity of construction activities. A series of semistructured interviews with experienced construction professionals show that the level of transformation, lead time, modularity, and the interaction of built components are some of the factors that determine the amount of sensitivity in construction activities to upstream design changes. These determinants provide for a quick assessment of an activity's sensitivity, which can help practitioners limit risk when planning the overlapping of design and construction activities.

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
