Very nice project. I would have had the excavator grade the pad area to sit higher and/or develop drainage swales around the building to direct surface runoff away from the building. After 4 decades of managing poor surface drainage at my workplace, it is one of my pet peeves about building site development. It is so much easier to address it before the walls are up. My facility looks like a Corp of Engineers project with all the swale work I had to do post construction.
