Please confirm whether an Indian Preference Plan is required. If it is, please provide further details regarding this requirement.

Page M-4 has been updated and replaced with this Amendment 0008.

3. Please confirm what grade Stainless Steel (SS304 or SS316is required as specified in Table 33 12 78B - Materials of Construction.

Contractor to recommend materials that are suitable for the conditions (operating, climate, water, etc.).

4. Table 33 12 78B identifies Pump Shafts and Flanges to be Stainless Steel, please confirm if this is the upper and lower bearing flanges.

This applies to all shafts and flanges that make-up the shaft-line.

5. Specification section 33 12 78 2.05 B requires 100% of the weds to be tested. 100 % of the weld test excessive, usually we go with a smaller % like 10% to 25% Magnetic Particle Examination ISO 17638, and 10%- 25% of the welded connection of the center tube to end flanges 0 tested by Ultrasonic Examination in accordance with ISO 17640.

Refer to section 33 12 78 2.05 D.4. If Contractor is awarded the contract, the Contractor can submit a RFI to modify the flange to end plate connection method. This process is done during the Contract phase, not Solicitation phase.

6. Specification section 33 12 78 2.05 D.4 states "Connect shaft flange to end plate with high-strength fasteners." Please confirm the following is acceptable: Use standard EDT threaded nuts and screw-threaded shafts to attach the upper and lower bearings to the screw tube. The quality of these shafts is C45, which is based on DIN EN 10083-2 and AISI 104 standards.

Refer to section 33 12 78 2.05 D.4. If Contractor is awarded the contract, the Contractor can submit a RFI to modify the flange to end plate connection method. This process is done during the Contract phase, not Solicitation phase.

9. Specification Section 33 12 78 2.17 Pump Factory Assembly and Test Requirements - full testing of the complete installation is not feasible at the factory as the assembly will be installed in a concrete trough. Please confirm lower bearing fit ups is sufficient for this requirement.

Refer to section 33 12 78 2.17. The concrete trough is not considered part of the assembly.

10. Specification Section 33 12 78 2.19 requires food grade non-petroleum lubricating oil and great. We will consult the manufacturers of the bearings, motors, and gear reducers.

However, if food-grade lubrication is not available or not recommended, will petroleum-based lubricant be acceptable.

Refer to section 33 12 78 2.19. If Contractor is awarded the contract, the Contractor can submit a RFI to modify the lubrication materials. This process is done during the Contract phase, not Solicitation phase.
