Even an old derelict building deserves a knowledgeable opinion as to its actual conditions, by an experienced Structural Engineer. How else will an inexperienced owner/buyer know what they have to deal with, and whether it is worth trying to buy or save? All of the above admonitions about contract language and our obligations, responsibilities, abilities and liability are absolutely applicable. But, owners still need an opinion from a knowledgeable third party who does not have a particular ax to grind. While there are plenty of good contractors out there, way too many of them will bias their opinions to the products or type of contracting services they offer. They are not really lying or acting fraudulently, but their opinion is not unbiased either. For example, you don’t often have a roofer tell you that you don’t need a new roof, after his free inspection. Although, this particular bldg. may actually need a new roof. Of course, you do have to be careful about what you offer or promise to do, about claiming what you can and can’t do, and about the wording of your report.
