I am calculatin a schedule for a tunnelling sewer (10 ft). A maintenance shaft (70ft) will be augered vertical from surface installing a steel pipe direct into the sewer. I require som data about the advance rate of this procedure.

ingseven, geotechnical / geologic / groundwater data is needed as well as information on the tunneling equipment. contact a tunneling contractor, review the data with him (on-site if possible) and you will get your answer
