I put in a call to our PM yesterday. He returned my call around 5pm. He answered all of my questions and addressed all of my concerns. Our basement is still gravel, so we don't have to worry about water damage to the floor.. whew! He said the sub flooring and framing should be fine. I'm confident that he'll double check to make sure it's ok.
Obviously, they lost a few days of work because of Sandy. They were scheduled to start back to work today. Our PM said the framing should be finished on Friday. That's really exciting! We should be ready for our pre-drywall walk through in about 2 weeks.
As a side note:
Our PM is awesome! At our pre-construction meeting he outlined the system he has for communicating with the home buyers (Is that what we would be called?). He does NOT give out his cell phone number. Instead, he has a number for us to call and leave a voice mail. He returns all calls on his drive home. He also gives out his email address, but he will only respond during the work day if it's a quick answer. If it requires him to type a lot, he will return the email from home in the evening.
I really appreciate his system! He also does a weekly update call every Friday to let us know what progress has been made along with what they plan on working on the following week.
