Ham, N; Moon, S; Kim, J H and Kim, J J (2018) Economic analysis of design errors in BIM-based high-rise construction projects: Case study of Haeundae L project. Journal of Construction Engineering and Management, 144(6): 05018006, ISSN 0733-9364
Abstract
Design errors are one of the major risk factors causing rework and delay. Therefore, accurate cost analysis of potential economic losses attributable to design errors is crucial from a practical point of view. This paper proposes a basis for establishing building information modeling (BIM) investment strategies by quantifying the various costs associated with design errors for error prevention. The design errors were classified into three basic types: simple design (Type 1); rework-related (Type 2) that may lead to demolition and rework; and delay-related (Type 3) likely to prolong the construction period. To evaluate the effects of BIM application quantitatively, the performance potential of BIM-assisted identification of individual design errors was examined. A comparison of the influences of classified design errors on the project revealed that the total cost of the design errors leading to schedule delay was 194.69% higher than that of the simple design errors and the direct design error costs due to errors leading to demolition and rework.

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
