Construction spaceships are specifically built for construction, naturally, their efficiency is extremely high. They had tons of experience dealing with things like the ground covered by tree roots.
You have to know that all of the plants used to green and embellish the entire mountain peak for this noble academy were all valuable. Even though they were not as valuable as the ones specified by Finn Lewis, their value was still considerable. The client's request was to completely uproot the trees, how this was going to be done, they did not care. For these construction companies, they naturally would not waste the trees.
These trees, if sold, would also be a huge source of money, which is why six construction spaceships were sent.
