8. Scope of Work: Offeror shall quote each of the following CLINs.

8.1. CLIN 001 – Transport, Evaluation & As-found Reporting

• Take possession of CO2 cylinders at Albeni Falls Dam. Total quality may vary depending on the number of cylinders available. There will be at least 48 cylinders and at most 62 cylinders.

• Transport the cylinders to Contractor’s facility.

• Empty each cylinder, reclaiming the CO2.

• Remove valve, visually inspect cylinder inside and out for pitting, corrosion or other damage.

• Fill each cylinder with water and hydrotest each cylinder to 150% of the normal working pressure.

• Measure the expansion of each cylinder. If the allowable limit of permanent deformation is exceeded, mark the cylinder as unserviceable.

• Make the overall determination of each cylinder’s integrity and fitness for service and document accordingly.

• Evaluate each valve, determine if rebuilding is possible. If not, note that valve replacement is required.

• Compile an as-found inspection report for each cylinder. One report is adequate for the entire lot, but each cylinder shall be identified by serial number or most recent recertification stamp.

• Submit the As-Found Report for all cylinders and valves to the Albeni Falls POCs.

8.2. CLIN 002 – Rebuilding of Kidde Type “I” Valves

• Quote parts (rebuild kit) and labor for one (1) valve rebuild.

8.3. CLIN 003 – Replacement of Kidde Type “I” Valve

• Quote price for one (1) new complete valve.

8.4. CLIN 004 – Replacement of 75-Pound Cylinder Assembly

• Quote price for one (1) new complete cylinder with valve.

8.5. CLIN 005 – Replacement of 75-Pound Cylinder

• Quote price for one (1) new cylinder (cylinder only, no valve).

8.6. CLIN 006 – Documentation and Recertification of Cylinders & Valves

• Quote price for complete documentation of work performed.

• The recertification record(s) shall identify each cylinder assembly, describe the work performed on each cylinder, and state that cylinder and valve are serviceable.

• It is permissible for Contractor to submit one record for each cylinder and valve, or to submit one document that contains the individual recertification information for the full lot of cylinders and valves.

9. Quality Control:

9.1. The cylinders will be inspected by the AFD Quality Assurance Representative (QAR) prior to the contractor taking custody of the cylinders.

9.2. To the extent possible, the QAR will ensure that the cylinders are not damaged, are serviceable, and are suitable for testing, refilling, and re-certification.
