The messiest (dust!) part was the cutting, though the hardest part was the chiseling. A jackhammer would have been nice, but was not absolutely necessary for a run this short.
I basically cut two, 2.5" deep lines about 4-5" inches apart the length of the trench. I then made a perpendicular cut at each end. The key to keeping dust down is to keep the area wet and the shop vac nozzle running and as close to the saw as possible while it is spewing dust. It took about an hour to make the two primary cuts. Slow, but easy.
After making the cuts, I went to town with the cold chisel and sledge. It took me about 2 hours to get out enough material to be able to cover my PVC. I used 3/4" and 1/2" conduit, so I didn't need to take too much material out.
Once that was done, i mixed up the concrete and poured it in to trench and smoothed it out. I also wiggled the PVC around to made sure that they were completely surrounded by the new concrete.
