Pour Aghajan, Marjan (2025) Supporting early decision-making between precast and in-situ concrete in construction industry. PhD thesis, Queensland University of Technology, Australia.
Abstract
This thesis examines decision-making in concrete construction, focusing on selecting between in-situ and precast concrete methods. Through literature review, surveys, and case studies, it identifies key decision factors, industry trends, and stakeholder roles. Using the Entropy-TOPSIS method, a decision-support model was developed to assist professionals in evaluating construction methods based on project-specific priorities. Findings emphasize scheduling, quality, environmental considerations, and logistical challenges. Validated through case studies in Queensland, the model enhances efficiency, sustainability, and project outcomes. This research bridges the gap between traditional and off-site construction, contributing to improved decision-making in the construction industry.

| Descriptive scope: | 5 PCTEA |
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
