Osuizugbo, I C; Onokwai, A O and Faleti, O O (2025) Principal factor analysis of project designers' roles in improving construction projects buildability in Nigeria. Journal of Engineering, Design and Technology, 23(1), pp. 88-107. ISSN 1726-0531
Abstract
Purpose: Construction industry is a vital sector for economic and national development. However, the industry suffers buildability problems. Improving construction projects buildability is the duty of every key stakeholder. Thus, this study aims to identify and evaluate the project designers' roles in improving construction projects buildability in Nigeria. Design/methodology/approach: This study adopted quantitative research method. A purposive sampling approach was used in identifying the representative sample for the administration of the questionnaire survey. A total of 122 questionnaires were distributed to the targeted construction professionals, out of which 93 questionnaires were sufficiently filled and returned, representing a response rate of 76%. This study used descriptive and inferential statistics for data analyses. Findings: The results from factors analysis show that the roles of project designers in improving construction projects buildability in Nigeria can be categorised into two constructs: "discuss fully the design objectives with builders" and "prepare cost effective and buildable designs". Originality/value: This study contributed to more effective buildability studies by highlighting the roles of project designers in improving construction projects buildability in the construction industry. An understanding of these roles is vital for reducing buildability problems as well as for improving and embedding buildability as a practice in construction management.

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
