Abstract
An investigation into nighttime construction operations at highway maintenance and reconstruction sites is presented in this paper. This investigation, which is part of a research project sponsored by the Illinois Department of Transportation (IDOT), involved two questionnaire surveys. The first survey is concerned with state Departments of Transportation (DOT's), while the other is concerned with IDOT districts. The surveys addressed issues pertaining to the different aspects of nighttime construction work such as the current practice in nighttime operations, construction-related factors, traffic-related factors, and social, economic, and environmental factors. Research results suggest that there is agreement between the two groups on many aspects of nighttime operations, however some other aspects received conflicting opinions. Many important findings were drawn from these surveys and are summarized in this paper. The study recommends the use of a more quantitative approach in dealing with some aspects of nighttime operations. This can easily be achieved on projects with dual shifts so as to exclude the effect of other affecting factors. The study also recommends the use of a separate bidding of nighttime pay items. This may not only prevent contractors from complaining about prices, but also result in more accurate and possibly lower bids. Also, any incentives provided in nighttime contracts should more reflect the expected benefits of nighttime work, particularly the savings in road user costs.

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
