Introduction of BIM Quality Standard for Quantity Take-off

As high-rise and irregularly shaped building structures have become a trend at home and abroad, BIM technology is now being developed and accepted widely. However, the BIM data and information generated in the design phase cannot be actively reutilized in the construction stage. This is because the major interests of construction companies include working process and cost estimation, while there is not usually enough BIM data created to support these activities. In order to resolve this issue, we need to set up BIM modeling guides that make it possible to extract correct quantity take-off from BIM data. Quality checks are also necessary to ensure that the resulting BIM data is correct. This study suggests ways of securing BIM quality for correct quantity take-off, which is critical for BIM technology applied to the building construction process and its cost estimation.
