I wanted to run this by some of you old "pipe hands" out there.
Specifically, i'm interested in the cost/benefit related to excavations for pipe work (eg, water, sewer, storm drain).
Do you guys have a rule of thumb (or preference even) to your backfill operations?
The following scenarios are most common in my mind (i'm not recognizing the "push dirt in trench and drive over with machine tires" method for purposes of this thread!):
1. compaction of backfill via excavator or backhoe with plate or sheepsfoot
2. compaction of backfill via trench roller or possibly ride on roller for larger , wider excavations.
I recognize other systems, but wanted to get feedback on the above two situations if possible. Specifically, do your firms have a break point when usings system 1 vs. system 2?
Tons of variables related to this i realize. In my minds' eye, if i can get an excavation wide enough for a given depth, i'd like to get a sheepsfoot ride on roller in the trench (for high PI material) in lieu of the backfill trackhoe as i expect that the cost of a second excavator for backfill work is pricey. Also begs the question: Have you ever placed a ride on roller in a trench deeper than the 5' OSHA shoring requirement w/o sloping sides or benching?
