“We both were very impressed with the project. It had to be a very tough project because of the layout of the roofs, the fact people are living there and the project oversight with Irvine, ABB, etc.

Your foreman, Aurelio Garcia did a stand-up job and should be commended. Dan and I had to laugh as he brought his red pen and couldn’t find anything to mark up.”
