Is it safe to work in Karbala

Dear All,
I am working in a construction company and we are currently in the process of preparing a budget for a new building in Karbala.
I want to ask couple of things, your reply would be highly appreciated.
We must go to Iraq with a team up to 40 people.

How is the working environment there, is it safe to live without any security or it is necessary.
Thanks you!
