I hired this company to provide architectural and engineering drawings for my office renovation which included a computer server room. They would only return calls after I called them 3 or more times, if they chose to return phone calls. Their engineer under spec'ed the air-conditioner for the server room, so it fails every 3 weeks. This constantly puts my company's servers at risk of over heating. Also, I've had to have the server room A/C serviced about a half dozen times. I had to hire a second engineering firm to diagnose the problem. Now I have to hire an engineering firm again to figure out how to fix the problem.
