About Tom Haws and Atlas Land Surveying
Long ago (2014?) Bill Barry affiliated with me as his civil engineering department head. Now that I rarely do any work that I don't give to NPS, any work that Bill needs me to do is done by NPS. The Board of Technical Registration told me I am allowed to be the registrants for as many companies as I want, subject to other rules.

Why don't surveys and GIS match?
You may have wondered why surveyors in the 2020's don't deliver their dwg files on standard GIS projection coordinates, whether UTM, US State Plane Coordinates, or something else. The short answer is that standard GIS projections usually don't give correct distances to the level of precision that real estate surveys need. I explain more below.

Solving Riprap Problems With Concrete Strips
Well-constructed loose riprap beds with proper elevation, gradation, filter layer, and subgrade preparation are a good solution to erosion. But riprap beds have some problems. Because they are uneven both on top and bottom, they obstruct debris and water and they dry or drain slowly.

Be a CEO at NPS Global Engineers
Dear top prospective colleagues,
We hope for you to be an NPS CEO some day.
Though the unusual reason NPS has for existing makes growth for profit meaningless, careful growth makes sense because more engineers deserve the NPS experience. One of the safeguards of the NPS experience is our Small Companies identity value. The Small Companies value requires one-team companies, meaning that our companies ideally have 6 to 8 colleagues. So for every team of NPS engineers, there must be a CEO.
I would love to add colleagues to NPS endlessly. I love being an engineer, I love what NPS has become, and I love finding the smartest people in the world. Our customers love working with smart, diligent, and attentive people. Hire, hire, hire! But not without more CEO's.
NPS exists to make great jobs and to do cool stuff. If your idea of a great job doing cool stuff might include being an NPS CEO some day, we may be ready for each other.
Sincerely,
Tom Haws
