Cutter;
The answer is yes. Yes you can hammer the pipe down through the cement and yes you can dig up under the floor under the pipe. The job is not the tough if you know what to do.
To dig out under the pipe place a waterhose on the end of a 4' piece of 1/2-3/4" PVC pipe and use the water pressure to clear the dirt out from under the pipe. You can also use a pressure washer. Filling the area above the pipe may be a problem but if you disturb only the earth necessary you should not weaken the floor much.
You should be able to hammer the pipe down with a mallet. I recently build 2 ICF structures and had to move the through pipes some 2 inch. I found I could hammer the pipe though the 6 1/2 inch concrete to adjust the amount extending throught the walls.
Do you need an engineer? No you need a plumber. Unfortunately I am also an engineer, but with advanced degrees.
Incidently I plumbed the water lines my barn with the crosslinked polyethylene. In this part of the country it was like taking your like in your hands as PVC is king. I plumbed around the exterior walls of the 40 x 60 ' barn to put in exterior taps and put in a bathroom. I turned the thing on and looked for leaks. I did not have one. The system was frozen a couple of times last winter but did not crack any fittings. We do not get to hard of a freeze here though. I understand it will with stand a hard freeze though.
