New clarification added: QUESTIONDear Sir/Madam:We wish to raise a critical concern regarding the compatibility between the mandatory component brands and the mandatory delivery timeline:Supply Chain Constraint: Current market data confirms that the specific Tier-1 European and Japanese sub-components mandated in the technical specifications are currently experiencing a global production backlog of 32-36 weeks. This duration for sub-components alone already exceeds the total 28-week project delivery window.Impact on Project Success: As this is a systematic industry constraint, any manufacturer adhering strictly to these brands will inevitably face a project delay of 4-6 months, regardless of their internal production efficiency.Clarification on Liquidated Damages (LDs): If UNOPS maintains the restriction to these specific brands despite the verified global shortage, will UNOPS provide a formal waiver or exemption for Liquidated Damages (LDs) caused by the lead-time of these mandated components? From a contractual fairness perspective, bidders should not be penalized for delays resulting from specific brand requirements that are mathematically impossible to fulfill within the current tender timeline.Risk Mitigation Proposal: To avoid the aforementioned delays and potential LDs disputes, will UNOPS allow "Internationally Certified Technical Equivalents"? By using equivalent high-tier components that meet all IEC standards and are available for delivery within 30 days, we can guarantee total factory completion within 150 days (approx. 21 weeks), ensuring the PNG power grid mission is completed on schedule.Our Question: Will UNOPS allow for certified equivalent brands for these critical components to ensure the 196-day timeline is met, or alternatively, will UNOPS waive LDs associated with delays caused by the mandated brands?Best regards,ANSWER Thank you for your comment. Please be informed that we have adjusted the requirement as follows: Bidders shall include Hitachi/MR brands in their bid as a mandatory requirement, and include other OLCT brands as an optional item. Bidder to quote for both types (time and cost).Delivery time will not be included as a pass/fail assessment. Bidders are allowed to offer alternative offer for OLTC between MR/ Hitachi/ Other equivalent brands Assessment of Alternative Offers:Technical Compliance: Every item must first pass a "Pass/Fail" technical evaluation. Delivery Timelines: If two items are technically compliant, the one that aligns best with the project’s critical path (delivery schedule) may be prioritized. Final Selection: Upon client acceptance, UNOPS will select the item that offers the best balance of technical compliance, cost, and lead time.

New clarification added: QUESTIONRegarding the transformers under Lot 2:The connection group is YNd11, which requires a high-voltage neutral bushing. However, the bidding document only specifies parameters for the LV neutral bushing (36kV, 600A, 25mm/kV) and does not mention requirements for the HV neutral bushing.We kindly request clarification:Is a HV neutral bushing required?If yes, shall it follow the same parameters as the LV neutral bushing above?Thank you for your clarification.ANSWER Yes, a High-Voltage (HV) neutral bushing is required.Please note there is a typographical error in the bidding document. Based on the specified YNd11 vector group, the HV side (33 kV) is Star-connected with a neutral while the LV side (11 kV) is Delta-connected.Yes, it shall follow the same 36kV, 600A, 25mm/kV.
