Abstract
Construction duration of a highway project depends on many factors, such as type of project, project size, weather conditions, project location, manpower, equipment, and construction management. It is important for a highway agency to be able to estimate reasonably the construction durations of highway projects. The highway agencies need to determine factors for construction durations so that they can be used to provide a contract estimation model that would be both accurate and usable. This article presents the research results on construction durations of highway construction projects. Through statistical analysis, we identified the effects of major factors on construction durations. Regression techniques were utilized to develop a contract time estimation model. The model contains regression equations, prediction intervals of construction durations with 95% confidence intervals, and adjustment coefficients of the major affecting factors.

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
