Abstract
Achieving efficient craft time utilization in the execution of construction projects is of great interest to project stakeholders. Craft time utilization assessment methods, such as work sampling and five-minute rating, measure the effectiveness of labour utilization, expose excessive non-productive time in the execution of construction activities, and reflect the soundness of workface planning. Onsite time utilization studies were conducted on 98 construction projects during the period 1972-2009. Statistic analyses were performed on the collected data to investigate the evolution of direct work rates and crew effectiveness over time, to gain understanding on craft time utilization patterns, and to identify improvement opportunities. The results of analyses suggest that, among other findings, the direct work ratio in construction projects and crew effectiveness in various construction activities have not improved during this period, and there is a statistically significant difference on crew effectiveness across different types of activities as well as in activities with different team size. The findings provide baselines to support the definition of craft time utilization targets in productivity improvement initiatives.

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
