here is some good info from Chapter 6

We’ve just published Chapter 6: Excavation Safety inside the classroom. This section covers some of the most important things every ground worker needs to understand before stepping into or around a trench — including trench hazards, protective systems, PPE, emergency response, and cave-in prevention. Excavation safety isn’t just theory — it’s knowledge that keeps crews going home at the end of the day. If you’re working around trenches, this is a must-know section of the course. Jump into the classroom and check it out. More modules coming soon as we continue building out the curriculum. 👊 ~Cody

Welcome to The Excavation Academy. This community is about how the work actually gets done — pipe, prep, compaction, grades, safety, and the details that separate clean jobs from call-backs. No influencer crap. No textbook theory. Just real-world excavation and civil knowledge. 👇 Drop a comment and introduce yourself: Where are you working (city / region)? What do you do right now? (laborer, operator, foreman, owner, etc.) What do you want to get better at this year? This group will grow based on real questions and real problems from the field. Let’s build it properly.

Way to go everyone it's been great week so far below I'm posting the current leaderboard. If anyone stuck on anything let us know.

I’m glad you had info on lasers. I learned how to grade with a peep scope and a pencil and paper. I was embarrassed to ask how to use one since I’ve been doing this for so long. Now I know how to use both.
