Micropile Clearance
Micropile Clearance
(OP)
How close can you install micropiles (100 ton; 9 5/8" pipe; approximately a 100' long) next support of excavation?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

"For a vertical micropile, the micropile centerline can be located within approximately 375 mm (15 in.) of the face of an adjacent wall. This distance may need to increase for micropiles larger than approximately 175 mm (7 in.) in diameter."
As said above, they can be placed even tighter to the wall obstacle (I have seen it), but the installers won't do usually except when under designer's pressure, and simply in other cases they can't (without supplementary defacing works). If one is not following closely the question, installers quite likely will drift to cozier tolerances, placing the micropiles 20" axis to wall or so, average.
