I notice that construction workers around my condo have been doing construction works during public holiday and sometime on Sunday.
The construction work is very noisy and we don't care if they do it for 1-2 hours only.
But sometimes they do their construction work from 10am to 6 pm during public holiday.
Is this allowed?

I think saturday is still ok.
But sunday and public holiday are bad, because everyone is at home and not working.
