Abstract
Buildability is one of the most important factors that influence labour productivity. Nevertheless, a thorough literature examination revealed a dearth of research concerning the effects of buildability on labour productivity of in situ reinforced concrete construction. Beams are major components of building floors, and the objective of this investigation is to explore the buildability factors that influence their micro-level formwork labour productivity. Therefore, a large volume of productivity data was collected and analysed using a categorical interaction-regression method. As a result, the main and interaction effects of beam repetition, size, intersections and span geometry were determined. The obtained results indicate that the investigated factors significantly influence the forming operation labour efficiency and substantiate the importance of applying design rationalisation, standardisation and repetition concepts to the design stage of construction projects. The findings satisfy the explored activity buildability knowledge gap, which can be used to provide designers with feedback on how well their designs consider the buildability principle requirements, as well as their decision consequences on the forming operation productivity.

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
