Construction on Shabbat

[yigael]

Hi,

If a non-jewish contractor is hired to complete a project, with out specific days of work identified, can work be done on shabbat by the contractor if they choose to do so on their own?

Thanks,
Yigael

No problem

Would I be correct that if this is done one one’s property by the contractor on Shabbat that it is asur?
