Help! rehab delayed 4 months already

[Amy Hu]

Our contractor was doing well with our SFH. So we continued to use her for our apartment building rehab. The contract sets 180 days for completion. Things seemed to go well at first then started to slow down due to utility problems. It's been almost 4 months past the expected completion date. Still not finished! We're told another month is needed!

How long does it usually take to get all utilities set? (inspection, meter etc for electricity, gas, water) 

I can't believe 5 months delay for this project when we were told it's 6 months' renovation. What shall I do? Help.  Thanks
