The excavator driver moves the Boom and arm very majestically
They are paving way for the drainage pipes
After done drilling he is trying to spread the gravel
He compresses it
He then moves in-front after paving his own way
He continues to drill it
It seems the rock is hard because we can see fumes
The boom and arm are at play
Its almost a minute the excavator driver drilling onto one place
But according to the look of things they will be able
To install one more drainage pipe
