Concreting of the shaft is the final step in the construction process itself. Up until this time, the Contractor has been willing to spend time with the Inspector but often this changes once the concrete is on the way. There are generally time limits, slump requirements, etc., a whole host of issues or potential problems that can occur during this phase. Remember, if concreting goes bad, the shaft is lost and everything the Contractor has done up until this point is essentially lost.
The Inspector needs to perform their duties promptly and efficiently. Speed is of the essence, but do not sacrifice quality and thoroughness.These duties may, depending upon the specifications, include performing standard field concrete tests, monitoring concrete placement and development of the placement curves.
