Provision of Services for Independent Performance Testing and FAT Verification of Pump–Motor Sets in China for UNOPS Afghanistan..

New clarification added: Question (4) Dynamic Balancing Testing:Dynamic balancing testing falls under the category of component inspection and is normally conducted before final assembly at the production facility. Alternatively, the equipment may be sent to a laboratory for disassembly and testing, which may pose a potential risk of damage.In the previous clarification, it was mentioned that the manufacturer could provide inspection records for review. Could you please confirm whether reviewing the manufacturer’s balancing records and documentation is still acceptable for verification?Response (4): Yes, for dynamic balancing and any other destructive inspection, reference the manufacturer’s documentation and traceable records to verify that the pump–motor sets comply with the contractual specifications. While the primary focus is on performance testing, the materials used and quality of assembly of pump-motor components are also critical for us; however, non-destructive testing methods are preferred wherever feasible.Question (5) Material Hardness Testing:Material hardness testing is typically a destructive test for raw materials and may involve damaging components such as the impeller. In such cases, the manufacturer would normally need to provide raw material samples as substitutes for testing.Previously, it was indicated that verification could be performed through the manufacturer’s material certificates and traceability documentation. Could you kindly confirm whether reviewing the manufacturer’s material certificates and traceability records is still acceptable for this requirement?Response (5): For material testing, we seek your expert advice. Our current understanding is that the inspection should focus on verifying the authenticity of the raw material test reports used in the production of the pump–motor sets, along with traceable evidence confirming that these materials were actually used for the units produced under our order. While material testing is recommended, we prefer to avoid damaging assembled components to obtain samples. Instead, it is recommended that material samples be taken from the manufacturer’s raw material stock (intended for production) for verification and testing.Thank youUNOPS Procurement Team

New amendment added #1: Dear Bidder,Kindly take note of the following changes made to this tender:The subject description of this tender has been changed from Provision of Services for Factory Acceptance Testing (FAT) Witnessing and Compliance Verification of 97 Pump–Motor Sets in China to Independent Performance Testing and FAT Verification of Pump–Motor Sets in China for UNOPS Afghanistan.The scope of services has been changed in section II: Schedule of Requirements.The price schedule description has been changed. The bid submission deadline has been extended from 07 March to 09 March 2026, and the due date for clarification requests has been extended from 03 March to 05 March 2026.If you have already submitted your offer, kindly recall it and make the required adjustments.Thank you,UNOPS

New clarification added: Question (1): Overall FAT Schedule and Time PlanningKindly confirm the expected overall completion timeline for FAT activities across the three manufacturers.Please confirm whether FAT activities at the three manufacturers will be conducted simultaneously or sequentially.In the event that re-testing is required due to non-conformities, will the additional witnessing time be considered within the original schedule, or will the overall completion timeline be extended accordingly?Response (1): Overall FAT Schedule and Time PlanningAs per the suppliers’ production plans, Factory Acceptance Testing (FAT) will be fully completed within ten (10) days after pump production is finalized.In accordance with the TOR, three (3) expert teams shall witness FAT simultaneously at each manufacturer’s facility. The FAT duration at each location may vary depending on the number of pumps per manufacturer.Re-testing shall be required only in cases of non-compliant results across multiple models or in the event of a critical failure (e.g., significant deviation from the approved technical specifications). Any additional time required will depend on the bidder’s timeline for reporting the issue.Question (2): FAT Testing RequirementsPlease confirm the required continuous operating duration per pump–motor set during FAT (for example, whether approximately 4 hours of continuous operation per unit is required).Kindly confirm the expected number of pump–motor sets that can be tested per day at each manufacturer.Please confirm whether FAT witnessing is required for all 97 individual pump–motor sets, or whether representative testing per model or batch is acceptable.Please provide the detailed breakdown of the 97 pump–motor sets by model and specification, in order to properly assess the testing setup and duration.Response (2): FAT Testing RequirementsAs per our QA procedure, the minimum continuous operation duration for the pump mechanical integrity test is two (2) hours.The exact schedule is not available at this stage; however, the maximum duration allocated for the Factory Acceptance Test (FAT) for each manufacturer is expected not to exceed ten (10) days.Yes, the FAT will be conducted for all 97 pump units, and the process will be fully witnessed.In total, there are 97 pump-motor sets with varying capacities ranging from 11 kW to 30 kW. Detailed technical specifications will be provided to the awarded bidder.Question (3): Testing Location and Capability ConfirmationFor standard pump performance testing items, please confirm whether all required tests will be conducted within the pump manufacturing facilities.Since electric motors are typically externally procured, and motor performance testing is usually conducted at the motor manufacturer’s facility, please confirm whether verification of the motor manufacturer’s test reports and certificates is sufficient.If independent laboratory testing of motors is required, kindly note that our facility can conduct testing for motors below 1.5 kW only. Higher power ratings would require engagement of an external accredited laboratory. Please confirm the expected approach.Dynamic balancing testing is generally conducted at the component stage prior to final assembly within the production facility. Please confirm whether verification of the manufacturer’s balancing records is sufficient.Material hardness testing is a destructive test for raw materials and may involve damage to components (e.g., impeller). Kindly confirm whether such destructive testing is required under this RFQ and whether manufacturer consent will be provided.Response (3): Testing Location and Capability ConfirmationThe testing checklist has already been shared with all manufacturers, and they have confirmed their agreement to conduct these tests at their respective facilities.Motor testing is included as part of the FAT checklist, and the manufacturer agreed to test it.No, all tests will be conducted at the manufacturer’s facility; no third-party laboratory testing is planned.All FAT activities will be carried out after production. Manufacturer-provided test records and documentation, with proper traceability, will be considered sufficient evidence.No destructive testing is recommended. Instead, all material certificates and their traceability documents will be reviewed to verify that the materials used in the manufactured pumps comply with the material specifications defined in the contract’s technical specifications.Thank you
