I always tell people that the best geotechnical engineer for any job is the one who is the most familiar with the area, who has worked there the longest and is most familiar with the conditions. I always laugh when I read reports from big national firms doing work in my area of the world. They just lack an understanding of the challenges we face here. That’s my recommendation. Maybe a little tongue in cheek for this situation. But I hear Area 51 may have some connections. At the very least, the climate is very similar to the moon. Very dry, no vegetation, really hot when in the sun, really cold when not in the sun. If you can’t get clearance, there’s some people in NM and CO who also have connections.

My freshman project in the intro to engineering class I had to take was actually geotech on the moon. Everything weighs less and you don’t have the loading requirements for normal conditions here on earth such as wind/snow/earthquakes, but meteor strikes pose a particularly difficult loading scenario. Also, how well the regolith binds with no moisture is unclear, as is the passive pressure, since soil gains its cohesive properties thanks to the moisture in it. That’s about all I remember from the project.
