Basement costs

Hi all. We are planning on building a home which we would like to have on a poured wall basement with 9’ walls. The plan is to have just under 1400 sq ft in basement area which will remain unfinished for the time being. My questions are, how much should we expect to pay for excavation and pouring the basement? We have been quoted 60k for the basement, but now the builder is asking us about meeting with our excavation/grading team. I assumed for 60k that would be the basement dug out and poured. We are in Georgia about 1.5 hrs east of Atlanta. Thanks for any insight.
