"I was wrongly sued and needed a property survey for building and zoning permit applications and a letter by an Engineer licensed to do work in Philadelphia. Alta Design was responsive to my time frame needs and testified in my case as an expert witness. If it were not for their expertise, I would have lost my case. I highly recommend this company, not only for your backyard project engineering needs but also for any property disputes and expert testimony at court hearing needs."
