POST TENSION INSPECTION
Post Tension inspection varies depending on the size of the slab, amount of PT and the level of inspections required by the structural engineers. The scope of services for a typical PT slab of about 100 cubic meters concrete are as follows:
- Observations regarding material handling and storage
- Pre pour visit to ensure PT tendon placement in accordance with shop drawings
- Pour monitoring to ensure protection of the PT tendons during concrete placement
- In situ concrete strength determination by Lok Testing prior to stressing
- Monitoring of strand pull force and corresponding elongation during stressing
- Monitoring tendon end capping and patching after stressing operation
- Supply of inserts and calibrated Lok test machine
- Provide PT summary report at the end of each slab pour reviewed by a senior technologist or a professional engineer
