Your surveillance agreement with PSC provides you with single-source service and accountability for: field technical assistance, labor, equipment, material, engineering, quality assurance/quality engineering/quality control, calibration, and training. Depending on your needs, we will tailor a program involving one or more of these areas.
PSC's field staff is composed of experienced construction superintendents with extensive backgrounds in both the installation of original nuclear post-tensioning systems as well as surveillances.
 |
| Trained personnel skilled in operating field equipment provide the physical manpower to conduct the in-service inspection. |
Our field personnel will:
- Perform and/or supervise the surveillance work
- Determine equipment needs
- Interpret and execute engineering guidelines
- Troubleshoot
On-site crews will provide the physical manpower to conduct the in-service inspection and perform any repairs or adjustments to the system that may be required, including the installation of replacement components.

| Hydraulic stressing jacks precisely monitor the force in post-tensioning tendons |
PSC has more stressing equipment and support scaffolding available than any other source in the industry. We have jacks ranging from 500 to 1,400 ton capacity. This broad range of equipment enables us to use the most cost-effective tools for a given job.
We can adapt our specialized surveillance equipment to any unusual circumstances your facility may have, providing you with important flexibility and accuracy.
 |
| Complete accesssibility to all types of tendons in a containment structure is made possible with versitile scaffold systems. |
Should your containment system need replacement components, PSC can supply gaskets, grease, shims, bearing plates, anchors, wires, and grease cans. This material will meet all original manufactured or approved equal requirements, whether safety or nonesafety related.
You will be able to verify the performance of your post-tensioning system by relying on our experienced engineering staff to provide a complete analysis of the system. The results are supplied to you in a final engineering report. Our reports have been used by utilities as the report of record or have been incorporated in the owner's documentation for the NRC.
Because of our experience in post-tensioned nuclear containment systems, we have a vast statistical database to which we can compare your current data. If a problem exists, we can recommend and implement corrective action as well as isolate possible future problems.
We can reduce the complexity of surveillance work and help achieve your safety and management objectives by assuming responsibility for each of the following areas:
-Procedure writing
-Review of technical specifications
-Calibration control
-Inspection, testing, and documentation of materials
-Training of personnel
 |
| PSC has the largest inventory of field equipment available in the industry to meet your exact needs. Shown here are 500-ton,1000-ton,and, 1400-ton jacks. |
PSC leads the industry in setting standards for jack calibration. There is industry-wide acceptance of our standards among major engineers and utilities. All equipment can be calibrated, traceable back to the National Institute of Standards and Technology (NIST). PSC has the largest first-generation load cell in the industry with a capacity of 3,500,000 lbs.
To enable you to become more knowledgeable, and participate in surveillance work, PSC will train utility personnel on site. The training includes classroom and field instruction, documented by PSC.
PSC is the only company with enough experience to get your post-tensioning surveillance completed efficiently and effectively.
