Sankaran, B and O'Brien, W J (2018) Bayesian second-order factor model for maturity assessment of CIM technologies and practices at highway agencies. Journal of Construction Engineering and Management, 144(4): 04018015, ISSN 0733-9364
Abstract
The work processes for highway infrastructure projects are undergoing significant transformations because of the advent of digital technologies for project delivery and asset management. Civil integrated management (CIM) encompasses the digital tools and practices that facilitate the collection, organization, and use of accurate project information throughout the facility lifecycle. With the increasing reliance on CIM technologies due to their proven benefits, there is a growing need to formalize a CIM maturity model that helps agencies gauge their CIM utilization activities. Through a survey of state transportation agencies and other CIM experts, this paper develops a quantitative approach to benchmark an agency's CIM capability. A multistage Bayesian factor analysis technique was used in this study. The study jointly analyzes the information from the relevant literature and the collected data on relative importance and actual implementation levels of 16 attributes related to CIM utilization. Results suggest the existence of three latent factors that adequately indicate the measurements on these attributes related to technology, processes, and organization. Furthermore, results demonstrated an overall CIM maturity score exists at second-order and can adequately summarize the measurements along the first-order latent factors. The empirical validity of the second-order model was demonstrated by applying this framework to the usage data of six U.S. highway agencies to benchmark their CIM maturity. The mathematical framework of this study can help highway agencies develop customized applications for maturity assessment and support decisions for prioritizing CIM investments.

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
