Qiao, Y; Fricker, J D and Labi, S (2019) Influence of project bundling on maintenance of traffic costs across highway project types. Journal of Construction Engineering and Management, 145(8): 05019010, ISSN 0733-9364
Abstract
Maintenance of traffic (MOT) is the process of providing transportation management and traffic control at highway work zones. MOT work is an essential part of any construction project and can constitute a significant fraction of overall project cost. It is hypothesized that MOT costs can be reduced significantly through project bundling (consolidation of several separate projects into a single contract). However, no existing study has quantified the impact of bundling on MOT costs. In addressing the issue, this paper develops statistical models that take into account the effects of bundling and other influential factors. Six construction work categories that involve 36 different project types were considered. Several significant variables were identified including the project cost, bundle size, geographical proximity, functional class, traffic volume, and letting season; It was found that the impacts of these variables on MOT cost varies significantly by project type. The study results can provide construction managers with knowledge on projects of specific attributes for which MOT cost could be reduced significantly by project bundling, and those for which bundling would have no such effect.

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
