Procurement of Five 30 kVA UPS Units with Installation and Commissioning at CATI Hyderabad

This corrigendum issued by **Pakistan Airports Authority (PAA)** modifies the bid submission date and time for procurement of uninterruptible power supply equipment and associated commissioning services at CATI Hyderabad. Bidders should treat this notice as an amendment to the original Invitation to Bid and should review the original bidding documents for the complete technical, commercial, contractual, and eligibility requirements. Mandatory item list: Sr. 01; EPADS No. 20071940550; procurement of 30 kVA UPS, quantity 05 units; scope includes installation and commissioning at CATI Hyderabad; Bid No. HQPAA/1992/682/XXLN. No unit price, estimated cost, model specification, warranty period, delivery schedule, or technical compliance parameters are stated in this corrigendum. The UPS systems should therefore be offered strictly against the specifications, drawings, schedules, and bill of quantities contained in the original bidding documents. The corrigendum does not state any change to bidder eligibility, bid security, tender fee, registration, tax status, or Active Taxpayer List requirements. No deposit, CDR, earnest money amount, or ATL condition is printed in this amendment. Prospective suppliers should confirm these requirements in the original tender dossier and ensure that all required legal, tax, manufacturer authorization, warranty, and after-sales service documents are enclosed. Any clarification should be obtained from the issuing logistics branch before submission. The revised bid submission deadline is **19 August 2026 at 11:00 Hrs**. Bids are to be submitted at Log. Center (S), Log. ANS Branch, while bid submission is recorded for opening at **19 August 2026 at 11:30 Hrs**. The notice does not provide a street address or electronic submission instruction, so bidders should use the address and procedure specified in the original tender documents. Practical tip: clearly mark the EPADS number and Bid No. on the package, verify that all five UPS units comply with the original specifications, and deliver the sealed bid well before the revised deadline. All other clauses remain unchanged. The corrigendum is also available through PPRA, EPADS, and PAA websites.
