2. Current NRC [or Agreement State] License to possess and use the source(s) they plan to bring to onsite testing.

3. Agreement with the CT DEEP in terms of using their source(s) in the State of CT.

4. Radiation Safety Officer to respond to emergencies in a timely manner.

5. Multiple radiation detectors that are up-to-date and in calibration, to monitor themselves, the source, and the perimeter for radiation doses.

6. Passed ‘leak testing’.

7. Written emergency response plan in case the radioactive source doesn’t retract back into its shield, or for other emergencies.

8. A security plan to prevent loss or theft of the radioactive material.

9. Written method/plan for determining the size of the restriction area and provide drawing showing the restriction area. Evaluation of the restricted area needs to include floors above, and adjacent to the radiation imaging areas.

10. Signs, ropes, and other barriers to clearly define the restricted areas to keep people away.

q) Perform radiographic testing of 100 percent of the welds. All radiographs shall be reviewed and interpreted by an ASNT Certified Level III radiographer, employed by the testing firm, who shall sign the reading report.

r) Use only domestic construction material in compliance with the Buy American Act.

s) Provide Construction work plan, Schedule, Safety Plan (Accident Prevention Plan), Waste Disposal Plan, OSHA worker certifications and training, Welder Qualification, Safety Data Sheets (SDS), weld X-ray inspection report and pressure test data from start to finish recorded by digital pressure recorder with full record and data to be provided to the VA.

t) Material submittals shall include the applicable VA specification section with applicable paragraph identification and shall include clear identification of specific materials proposed for project.

1. Manufacturers’ Literature and Data including: Full item description and optional features and accessories of the complete system including, but not limited to, dimensions, weights, materials applications, standard compliance, model numbers, size and capacity. Submit Pipe and tubing, with specification, class or type, and schedule. Pipe fittings, including miscellaneous adapters and special fittings. Flanges, gaskets and bolting, Valves of all types, Strainers, Gauges, insulation, and all other steam system components.

The project shall be accomplished in compliance with all applicable standards and codes specified in the VA Design Guides and Manuals and all applicable VA requirements. VA specifications can be found at the VA Technical Information Library: Technical Information Library (TIL) - Office of Construction & Facilities Management (va.gov).

The most stringent requirements of the SOW, local codes or the specifications requirements shall always apply. Any conflicts shall be brought to the attention of the COR.
