1/20/13 Update: Gasline and footer drains trenched.
Picked up the trencher at 7:30 Saturday morning and was trenching by 8:30am....it took roughly 3.5 hours to trench 500 feet of gasline in and backfilled, granted I went a little deeper than code. The ground was pretty hard in spots and the machine, while the being the largest they rent, just seemed to be lacking in power (I think these rental machines just get tired over the years and lose something).
Got the 120' of footer drain trenched in, tied in and backfilled. Today is the electric which only needs to run about 100 feet and with the cold temps, the top layer of ground should be good and stable to support the weight of the machine in the soft spots.
I will get some pics of the machine in action today.
All rough plumbing is now done and we start pulling water lines today.
