excavation question for contractors
(OP)
Let's say an excavation is proposed. Prior to excavating, secant pile walls are installed to create a bathtub. Proposed depth of excavation is 30'. Water table is at 10' depth, but dewatering with wellpoints is expected. The excavation will be performed in the middle of a multi-lane local road. The excavation will be 55' long, measured in the direction of traffic.
What type(s) of excavator would you use? How much time would it take you if the cut took up one lane only? What if it took up three lanes?
Please spell out the sub-tasks. This is the excavation portion only. No dewatering, no installing support of excavation.
Thanks.

As the excavation gets deeper, wet soil is more likely to resist digging, if the crane has to swing full arc (180 degrees) to unload (carefully) into dump trucks, the rate will slow down significantly. Maybe 1 cycle per minute.

Does traffic have to be maintained?
The answer will determine whether large, speedy equipment is practical for this project.

What are you building, a sewer for DDC? Out of curiosity, is the city giving you long term lane closures of the usual daytime & nighttime hours?
Two days to move an oil static line might be optimistic.
