Thanks for the video. Great job

Skip the music, it’s annoying.

what weight and horsepower was require to put that line in?

There is a much better way to do tie-ins. As is being done here, the open trench that the excavator makes offers virtually no side support for the pipe due to the width of the trench and no groove to provide two point support for the pipe. If you've ever dug one up after a couple of years. you can se that the pipe is deflected 30-50% causing as significant loss of capacity.
