Hdb Rectification Considered Dong Tu?

[jopp 0]

Hi, need some urgent advise here.

Understand dat it's impt to get an auspicious date for commencement of renovation works aka. Dong Tu.

For my new house, i need to get HDB contractor to rectify some defects first though.

Is this considered Dong Tu? Do I need to adhere to Dong Tu date?

Thanks a lot!
