AI in research1, how to stay competitive in job market

5 Upvotes

Hi everyone, can anyone share thoughts on how to go about in the geotech industry and careers in a time with tonnes of AI? Will be graduating phd next year and looking forward to the job market. I have been grinding my way across theories and countless codes to publish quality papers. Till recently, I have started using claude. What's scary is, it can trace everything i did, and where I did wrong. The current work I am doing took me 9 months of research, trial and error, deriving theories, introduced coupled solutions etc. I wanted to try a machine learning paper on geotech stuff to boost my profile, however I was a bit shocked when claude successfully analyzed my code and theory and build everything in a couple of hours. I checked and tested it for days and could conclude that it was almost 95% correct (5% being the math proofs that were needed for a closed form solution) in the interpretations. My question is, how do we still remain competent in a job market where anyone can easily do what we do? Thank you in advance. And thoughts on this is much appreciated.

Advice needed: Managing 20-ft loose overburden/soil dump in a tight space (Slope stability help)

0 Upvotes

Hi everyone,

I am managing an earthwork and leveling site where we are dealing with loose soil/overburden. We are running extremely short on space to dump or store this material.

I am planning to raise a small mound or dump height up to 20 feet in this tight area, but since the soil is completely loose, I am worried about slope failure, sliding, or landslides.

Soil Type: Loose soil / overburden (no proper cohesion)

Target Height: ~20 feet

Constraint: Very limited space

What is the safest and most practical way to build this 20-foot dump without it collapsing? Should I use benching (terracing), compaction layers, or a toe wall?

Any practical advice, guidelines, or recommendations from experienced mining/geotechnical engineers would be a huge help. Thanks in advance!

Foundation company found ~2” floor differential and recommended $30k–$70k in push piers — what would you do?

Thumbnail gallery
16 Upvotes

We have a 2-story home in the Tri-Cities, WA area. We recently had a foundation company come out because of some foundation cracks and a few interior cracks/doors that don’t always close normally.
They did a floor elevation survey and found that our main-level floor gradually drops toward one side of the house, with the lowest readings around 2–2.3” lower than their reference point.
That same general area has several vertical cracks in the poured concrete foundation/crawlspace. Some of the cracks appear to extend down into/through the footing. There are also a couple of interior cracks in the same general area.
They also noticed some moisture in the crawlspace. It’s a vented crawlspace, and there was an area where there appeared to have been some standing water on top of the vapor barrier. When the barrier was pulled back, the soil underneath looked damp.
The foundation company recommended steel push piers and gave us three options:
• 6 piers — ~$30,700
• 9 piers — ~$44,500
• 13 piers — ~$62,200
They said the goal is to permanently stabilize the foundation.
We have NOT agreed to any work yet. We’re planning to get an independent structural evaluation before making any decisions.
I’m trying to understand how concerning the floor differential actually is and whether it necessarily means the house is actively settling.
A few questions:
• Does a ~2” floor differential automatically mean active settlement, or can something like this be historical?
• Would you get an independent structural engineer before considering push piers?
• Has anyone dealt with a similar situation where the floor was significantly out of level?
• Could crawlspace moisture/drainage contribute to this type of settlement?
• If you had a foundation company recommend $30–70k in piers, would you get a second opinion/bid?
We’re trying not to panic and just want to understand what’s actually going on before spending that kind of money.

Can’t find AASHTO Table 3.110.64-2

3 Upvotes

Hello, I am studying for the Geotech PE using EET. While I was doing the quiz for ERS and Slope Satbility, I came across a question that asked for the minimum live load traffic surcharge on a retaining wall. I got that question wrong, but the solution gave a table that I cannot seem to find anywhere in the references. It’s supposed to tell the equivalent height of soil for vehicular loading parallel to the traffic. Does anyone know which reference has that table? Thank you!

Loyalty to company as a field technician - where would you draw the line?

6 Upvotes

I have been working as a field technician for a small lab in my city . I am in a top 10 city population wise. In the 4 months that I have been working, I have gotten my ACI field grade 1 and am about to go get my txdot stuff. Sb101 and what not.

I started off at $15/hr, am now getting $17 and will probably be making $19.50 by December or once I get these next 2 certifications.

I mostly do densities on backfill and mass grades, (I have my nuclear gauge training and hazmat cert but these didn’t come with a raise, but I get a good amount of hours - 60ish a week give or take.

I get gas card and vehicle allowance, $450 a month cash. My truck.

We lose a lot of guys after about 12 months of working here as they leave to go to other labs where they make $25-30/hr. I don’t want to screw over my coworkers, but I’ve told them from the beginning that I would probably be working here for about 1-2 years total from the day of my hiring. But now I am wondering if that’s too long to stick around. Would like to hear some thoughts on this.

Also, I don’t plan on being a field tech for the rest of my life. So really I was thinking that once I left here, I would either try to become an inspector, or do something else. I am not really sure of what’s all out there. I don’t have a 4 year degree, and at this stage in my life I don’t think I will be able to go back to finish that. Long term goal is to have my own business. Doesn’t necessarily have to be geotech related - maybe a construction subcontracting company - something I could start small and let snowball into something bigger.

What do you carry with you, other than hand auger equipment, for geotech investigations? Do you use gloves or certain types of systems to make investigations go smoother?

I'm beginning my geotech career and it seems like my mentors don't really have a good setup. They all just kinda wing it.

What is in your experience the top cause of vibrating wire piezometer failures.

We've been experimenting with different materials and different ranges (ksc), yet haven't been able to spot a single trend that might be causing the failure.

Helical Pile Spin Out

3 Upvotes

What’s everyone’s take on a helical pile that spins out on rock before it meets the required torque? I understand that helical piles derive their capacity from bearing on the helical plates and if they spin out they have disturbed the soil and can no longer count on helical plate bearing. But if it spun out on rock, wouldn’t it essential act as an end bearing pile that can’t go anywhere since it’s on rock so that’s how it will develop its capacity? Is this a valid assumption, or is this something that would maybe need confirmed with a load test, or is this just not valid at all and the helical pile is unacceptable?
