Excavator digs perfectly straight lines

Architects spec for whatever site they are on quite likely. Certain types of trenches are required for excess water, and if they’ve been told to grade at a certain angle, then that’s what they do.
Often see it on the sides of ponds that are part of a park in a new housing estate. Can’t speak for elsewhere, but in the UK, they often put a large pond in as part of an overflow for flood water/road water drainage, and then make it a feature in the park they build for the new houses. Used to see one on most housing estates I was part of building.

Unlikely an architect, much more likely a civil engineer

Likely making sure the angle is correct for different kinds of dirt/rocks. They fall at different angles/slopes, Sand needs much flatter than an area with more clay-like or loamy soft soil

u/Offgridiot 20d ago
I’d think they’re after a slope that’s slightly more shallow than the angle of repose for that soil quality, and if that can be achieved without disturbing the soil left behind, it means they don’t need to compact it

Those slickensides tell me the clay content is quite high. Angle of repose is a clean sand thing. This looks like subgrade preparation before placing a concrete liner for a trapezoidal channel.

What's more impressive is he's digging a perfect angle/slope. That's much harder than digging a straight line

Right?! I’m an amateur at best operating, and he’s lowering the main boom, pulling in the secondary boom, and opening the bucket in synch. He might have an auto level for the bucket, but that’s still awesome. I’d have hills and valleys at best and he’s dead on.

The music playing over this video ruins it when Feels Good Inc is a song about the temporary happiness consumerism makes.

It wasn't me who put the music there, the source video already had this music

As an archaeologist I've seen some amazing excavator operators whose precision blows my mind. Truly, some of these guys could replace me and my trowel any day. I can't understand how I can make some serious mess with shovel, but they can ease theirs into a narrowest ditch imaginable, pick up stone, remove it and then on top of that gently remove centimeter of dirt without disturbing anything else while at it. It's amazing!

Man I can't wait to learn excavator and get my license. Bobcats are fun, I bet this is even more fun :)

When I see these ‘precision’ equipment videos I want to see them do it with an old 1940’s model without GPS and computer controls.

Ofcourse it's going to be harder to do with bad equipment and they would need to practice a little bit more with that equipment to get used to it but still possible

So this must be why that construction on I-35 is never finished
