Wang, T and Feng, J (2023) Optimal review strategy for concurrent execution of design-construction tasks in DB mode. Journal of Construction Engineering and Management, 149(1): 04022139, ISSN 0733-9364
Abstract
In traditional design-bid-build (DBB) mode, due to the sequential execution of design and construction, the review method of construction documentations is a one-time review at the beginning of the construction phase. However, in design-build (DB) mode, to realize the concurrent execution between design and construction tasks, the review method of construction documentations is multiple reviews during the concurrent execution, and the problem of when and how to review under this review method has not been solved yet. Therefore, dynamic and static decision models are creatively constructed to solve when and how to review. Based on the dynamic decision model, the influence of the execution of the review strategy on the preparation duration, review duration, executable tasks and rework duration during construction was discussed. Based on the static decision model, the influence of design accuracy, construction sensitivity, and review efficiency on the review method under different time ratios was discussed. The research achievements provide operational countermeasures for exploring the principles of developing review strategies in the concurrent execution process from the perspective of quantitative analysis, and also provide directional suggestions for the way of applying concurrent engineering in DB mode.

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
