Abstract
Several factors affect construction labour productivity, but one of the most important is buildability. Despite the plethora of research into labour productivity, a thorough examination of the literature revealed a dearth of research into the influence of buildability factors on the labour productivity of in situ reinforced concrete construction. Since walls form major parts of many reinforced concrete structures; especially slab-wall structural configurations, the objective of this research is to investigate the influence of the wall surface area and perimeter geometry on formwork labour efficiency. To achieve this objective, a sufficiently large volume of formwork productivity data were collected and analyzed using the multiple regression method. As a result, the effects and relative influence of the shutter surface area and the number of angles formed along the wall perimeter on formwork labour productivity were determined. The results obtained show significant influence of the factors investigated on the efficiency of the formwork operation that can be used to provide designers with feedback on how well their designs consider buildability, and the tangible consequences of their decisions on labour productivity. On the other hand, the findings provide guidance to construction managers for effective activity planning and efficient labour utilization.

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
