I am often asked how long I have been in the land survey business. Although I have made my living in surveying for over 35 years, I actually started when I was 7 years old. My father, Charles Douglas Irvine, was both a Registered Civil Engineer and a Professional Land Surveyor, and it was my great privilege to learn and work at my his side.  He taught me how to survey using a slide rule and drafting by hand. He also taught me the importance of integrity in doing my best work.

At I/WS Surveying, our staff and partners hold these standards of excellence and span backgrounds not only in surveying, but in design, drafting, building, and business. We combine state of the art technology with old-fashioned principles I learned from my father.
