There are limited LIDAR sites available in some areas. We use one to help determine whether a mapped earthquake fault is in the vicinity of a project site.
Some county offices have rough contours available on their GIS maps. My experience is that these are slightly better than using the USGS Topographic maps. Most of the civils I work for just trace the county contours onto the plan to start, until the survey crews can get to the site.
A graduating engineer with zero experience is going to start at the bottom and work their way through the foundational portions of the industry. Some of these tasks can seem mundane, unpleasant, and just plain miserable. Without some of these experiences, you won't turn into a good engineer...
Tell us more about these micropiles. Does their load carrying ability come exclusively from the soil to grout interaction? Are they end bearing into a stronger layer of soil/bedrock? Are the loads all compressive, or are there some tensile loads? What about steel within the element (size...
Sounds like you have a free-draining sand that will be placed similar to a "rock" fill. 5 cycles of vibratory compaction should give sufficient stability of the material. Will there be a pavement on top of this sand? How is it supposed to remain dry after placement?
I think the point has been missed. Nobody seems to like the update. This site used to be a great forum to discuss various topics and help one another find solutions.
Now, we can't find anything that we are used to viewing.

If you construct a big block of concrete as shown in the above diagrams, where do you drain the water to from behind the wall?
The wall should have been constructed to a couple feet below finished grade. You may need to do some localized grading to bury the first couple rows of block, again...
The suppliers I have dealt with in the past try to make the fewest products that meet the widest range of standards. Example: they produce a #67 stone that can be used in concrete, or as drain rock.
Once everything has passed through the grinder pump, do you really have solid particles? The last one I designed was treated as regular water for all the calculations.
In any discipline, there are those clients that will always claim, "But company X says they can do this project for less."
Even in public works projects, you will encounter project managers that try to bid the design services, despite the requirement of following QBS guidelines. When working...
Most of the samples I ever tested were a processed concrete sand. The particles are quite rounded in shape and very durable. The test is tedious at best. I just sit down and start picking up individual particles from the pan, rolling them, and placing them in the second container. I set up to be...
If memory serves me correctly, your sample size should be small enough that it doesn't take long. C142 includes a table specifying the size of sample to be tested for fine aggregate. I think it's about 25 grams, could be more.
You can have a PE license with a status of "Inactive" in several states. I never understood the reason for such a status. I have let 3 state licenses lapse, since I'm no longer engaged in those markets.
The amount of roots shown in your images would not concern me. Any further consolidation due to decay of root matter is not likely to manifest to the top of a 14 meter embankment.
When you say a layer of rock, are you referring to gravel, or a rock fill material including cobbles and boulders...
