Pattison Sign Group had us do 4 surveys on some Holiday Stations in Michigan months ago we send a follow up to see what the issue was and they said they were not adaquate for their needs. We are a sign company I guess they wanted the size of every logo on the gas pumps and we did not

measure every single sticker and we did not verify every color on all the pump stand and so on.  Like I said we are a sign company and all the measurments for the signs, canopy & building will be there and correct.   They can pick any reason they need to say that so be CAREFUL if you think you are going to be paid that might not be the case, like I said we are a sign company not an everything company. Just thought you might want to do some research before you get in to deep. We live in a very distant area from any larger cities so when it comes time to get their work done it will all come out in the wash. Believe the cost will be much more then if they were a straight  company.  Keith
