Abstract
At state transportation agencies (STAs), construction inspection is pivotal to ensuring infrastructure quality. Due to current challenges, STAs have been exploring a risk-based inspection strategy. However, the lack of a systematic approach for risk identification and assessment at the construction activity level is the main limitation. Therefore, this paper introduces an integrated risk-based construction inspection framework by developing a risk breakdown matrix (RBM). Using RBM, critical risks are identified and assessed at the construction activity level. The overall framework is evaluated by using the concrete pavement project as a test case. Results show that the framework could provide risk information (e.g., risk rankings) of construction activities as well as the overall project risk level. The major contribution is that the proposed framework can be applied to various infrastructure projects at STAs, allowing for effective inspection resource allocation, reduction of the inspector's workload, and consistency in inspection practices.

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
