Abstract
Purpose: Prefabricated construction technology enables relatively faster and easier construction of building structures at a lower project cost, providing improved quality control with minimal material waste. Despite the advantages of prefabricated construction systems, they are not extensively used in Turkey because of specific yet largely undefined challenges. Therefore, the purpose of this study aims to determine the factors currently affecting the extensive use of prefabricated construction systems in Turkey. Design/methodology/approach: The reasons for such systems not being used extensively in Turkey were examined using responses to a questionnaire distributed amongst architects working at design firms, prefabricated-building manufacturers and contractors. The obtained survey data were statistically analysed using the SPSS 22 and LISREL 8.7 software to rank the severity of the identified challenges and determine the most critical factors. Findings: Eight critical factors groups affecting the use of prefabricated construction systems and their associated factors were identified according the responses provided by the participants. Potential solutions and recommendations were proposed based on these factor groups that are expected facilitate the implementation of prefabricated construction systems in Turkey. Originality/value: Little previous research has provided insight into the specific factors limiting the use of prefabricated construction systems. This study accordingly approaches the subject considering all phases of prefabricated construction systems and presents a structural model of the factors obtained by a confirmatory factor analysis for application to expand the use of prefabricated construction systems.

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
