A tendon reaches pressure but not the expected elongation
A post-tensioning team has reached the target gauge indication for a tendon, but its recorded elongation is outside the project's permitted range. The technician can identify the tendon, yet the available calibration sheet belongs to a different jack-and-gauge combination. A strand tail has not been cut. Another worker suggests increasing pressure until the elongation matches, then recording the target value to keep the job moving. Nearby, the grouting crew reports a damaged duct connection and asks whether extra mixing water can make the grout pass more easily. The supervisor must prevent unsupported corrective action, preserve the evidence needed for review, and keep the stressing and grouting processes within the authorized system requirements.
1. What should happen to the stressing discrepancy?
Read the worked answer
Hold the affected follow-on work, preserve the actual readings and tendon identity, and obtain the specified review. Confirm the correct equipment calibration and investigate measurement or system causes. Do not arbitrarily increase pressure, invent an elongation record, or cut the tail before required acceptance.
2. How should the duct and grout concerns be handled?
Read the worked answer
Assess and resolve the damaged connection through the approved system repair or disposition process. Grout proportioning and testing must follow the specified product and project limits; uncontrolled dilution is not a suitable response to an obstruction or poor duct condition.
