Abstract

Determining productivity targets based on actual potential for productivity improvement; is essential for fostering continuous improvement. Developing realistic and work specific productivity targets has proven a huge challenge in on-site construction. The present research exemplifies how work measurement techniques can be used to identify improvement potential and develop such targets. Two work measurement techniques; work sampling and continuous time study have been applied during a five day period, where the installation of prefabricated concrete elements have been observed at a single project case. The study revealed high fluctuations in daily utilization and productivity rates; moreover, a strong relationship between direct work and productivity at work task level were identified (R2 =.827). Additionally, four managerial strategies for improving productivity were identified: (1) Enhance production start and stops; (2) improve flows; (3) optimize utilization of manning and avoid absenteeism; (4) shield the production from weather. To develop a realistic productivity target, the observed productivity day-curves have been modified, by adjusting for effects of variation and declines in productivity, revealing an improvement potential of 19.4%. The present study demonstrates how realistic productivity targets can be developed to support managers' and managerial decisions and thus act as a starting point for continuous improvement.

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
