How to choose a civil engineer?

[Forrest Shealy]

This will be my first time needing a civil engineer, or any engineer. I will mostly need them to overcome some challenges getting sewer service to the property. It is a basically flat property with good drainage and we are using a standard size steel frame construction, so the other questions should be easy. It is only a 6000sf building and affordability is and affordability is a major concern. How do I choose? What questions should I ask? 

I understand I will have to spend money, but I want to know if these sewer issues push us over budget or just eat the margins, before we spend too much.

Thank you!

Call companies.  See if you can talk to engineers.  If you can, ask them what they think and how they price their services.  Ask them how much their projects cost, and who bids out the design docs.  Trenching, digging, etc... Isn't that bad.  As the guy at the equipment place said, 'live a little,' and rent it yourself.  Good plans let you do that.  Good plans also let you get <$1000 for the actual 'heady' plumbing work.
