Phased mandatory application of BIM based on project scale
o 2023 : mandated for public projects valued at over 100 billion Korean Won (roughly 70 million USD).
o 2026 : Extend to 50 billion KRW (≈ 40 million USD)
o 2028 : Over 30 billion KRW (≈ 23 million USD)
BIM Strategy of Korea Mandatory application of BIM in the design and construction phases
BIM required for public projects over 30 billion KRW
BIM required for public projects over 100 billion KRW
BIM required for public projects over 50 billion KRW
From 2023
Construction of first-class facilities such as roads and railways
Construction of second-class facilities such as bridges and tunnels
Construction of third-class facilities such as buildings
From 2026 From 2028

Survey: Will the introduction of BIM eliminate the need for paper drawings at construction sites?
It won’t be necessary
It will be necessary for the time being
It will continue to be needed
