We hired Dave to build the "inside" framing for one room of a sound studio. This entailed building, essentially, a "room within a room", with strict rules as to where and how the new framing could contact the existing building, so as to not compromise soundproofing. This kind of work requires great attention to detail that contractors are not used to at the framing stage. Dave exhibited a great attitude throughout, he and his crew were a pleasure to work with, and in the end I ended up with what I needed. There were a couple items that were specified in the plans and engineering drawings that didn't get done: four braces that I ended up installing myself; and rafter hangers that were specified in the drawings weren't installed (Dave brought this to my attention at the time & I was ok with it, but the inspector made me put the hangers up anyway). In addition, I had sent a "final" version of the drawings to Dave via email the week before he was to start, but these didn't make it into the hands of his crew, which caused some confusion (resolved, but some things had to be re-done). Issues aside, one big plus for Dave was: the plans called for a large soffit around some ductwork, and it was unclear as to how to build it such that the soundproofing would be maintained - Dave came up with a creative solution that fit the bill perfectly. Like I said, in the end it was a good experience and I got what I needed.
