Abstract
Purpose: The construction sector suffers significant challenges which are intertwined with processes and products of the traditional onsite construction approach. The quest for a lasting solution to these problems is heralding the change toward offsite construction. Amid the scaling drive, to date there are no official reports and contribution to knowledge on the drivers of offsite construction in Ghana. This study models the structural paths of the critical drivers of offsite construction in Ghana. Design/methodology/approach: Data were collected through a questionnaire from 95 respondents in the Ghanaian construction industry. Exploratory factor analysis and Partial least squares structural equation modeling were employed to analyze the data. Findings: The results revealed that industry dynamics are the governing drivers of offsite construction in Ghana. As such, factors such as the rocketing housing deficits, high cost of acquiring land permanently, high cost of cast-in-situ construction, the utilization of prefabricated shipping containers for construction and construction market demand constitute the governing drivers of offsite construction in Ghana. Similarly, concern for higher productivity is a critical driver of offsite construction in the Ghanaian construction industry. On the contrary, findings show that performance-related drivers, government policy and regulation, and technological innovation exert little influence in driving offsite construction in Ghana. Practical implications: The appreciation of the drivers may help stakeholders to understand the important mechanisms underlying offsite construction in Ghana, and thereafter help them to make more informed decisions regarding its implementation. Originality/value: The findings contribute some interesting dimensions to the global debate on offsite construction by discovering and adding two drivers of offsite construction peculiar to developing countries (high cost of acquiring land permanently, and the utilization of shipping containers for construction) to the literature.

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
