excavation

That is going to be one toxic excavation, I hope they wear the proper protective clothing.

But I know Italy and other places in Europe have laws that require an excavation to be done to look for historical stuff.

Two weeks into excavation, the project engineer tells the contractor "oh, that tunnel needs to be built 20 feet deeper and moved 15 feet to the south.

Judging the type of ground of the excavation site at the photo, it seems to contain a rather high amount of clay, which is a terrible foundation.

Major underground excavation isn't really possible when ground level is only 10m or so above sea level/the water table.

Some excavation could possibly be automated on probably on greenfield sites.

The ground conditions in Seattle require that the machine be able to control the rate of excavation at all times such that a large sink hole does not form due to uncontrolled loss of ground.

It's an interesting little bit of historical excavation.

In my time designing lunar excavation equipment, much of our problems arose from the intended location: permanently shadowed regions of craters.

3D printed houses are still going to need some conventional building work -- they need stable foundations, just like any other building, which means some excavation and levelling, and piles in unstable or waterlogged ground.

However, excavation was abandoned as a result of uncontrollable ground-water flooding.

While reading this, I kept thinking to myself that while excavation seems an insurmountable task at this time, if things started via a tunnel excavation from the coast that was already 150' below the surface, then building up from there wouldn't necessarily have been a major endeavor at all.
