Abstract
The last decade has witnessed a proliferation of Off-Site Construction (OSC) operations and systems in the UK in response to persistent performance challenges in the construction industry. However, understanding the real influences of cost modelling for accurate project costing and cost performance remains limited. Consequently, this systematic literature review aims to identify the key parameters associated with effective cost modelling in OSC systems. Using literature in the last 10 years (i.e. 2011–2021) and keyword search terms, the review covers OSC aspects such as cost modelling and models, life cycle costing, cost analysis and taking off. Knowledge gaps are identified within literature and practice in cost modelling despite a backdrop of a proliferation of OSC systems and concomitant literature. Emergent findings uncover thematic clusters in analysed literature with the role of design, 88%, costs, 69% and modelling, 74% dominating the literature reviewed. Moreover, key influences to cost modelling in OSC (e.g. abnormal costs, factory-based preliminaries, and contractor’s overheads) do not feature prominently in any published research. This paper provides a cross-sectional snapshot of contemporary developments in the field and highlights the need for new research to support integrated cost modelling to support current OSC practice.

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
