Blue House Residence Restoration Project

I heard Heerim, the same company that worked on Kim Keon-hee's Yongsan residence,
is doing this. Is this true?
Isn't Heerim under investigation by the special prosecutor??
They were criticized so much for being a problematic company,
yet they even got the Blue House project...
I guess they are actually good at construction.
Then why have we been criticizing them all this time?
