Abstract
For the most part, existing productivity forecasting models are based on extrapolating from historical data instead of considering the effects of project-related factors. These factors can change daily and can significantly affect the productivity of a labor-intensive activity. This paper describes a statistical model developed to forecast the productivity of masonry activities. The model is an additive regression model and is based on data collected from 11 masonry projects. The model was tested by predicting the productivity of the 11 projects, with seven of the 11 being predicted within 10% of the actual productivity. This is noteworthy, given that the projects included a number of different masonry activities and types of facilities. Other analyses of the model indicate that the model is statistically valid and reflects what would be expected. Construction managers could easily use the model to estimate the labor requirements for a project and then to better manage the project as it progresses. Other labor-intensive activities could be modeled using the same methodology.

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
