Baku Metro Expansion Project - Phase II (Green Line)

NOTICE OF INVITATION TO PARTICIPATE IN EARLY MARKET ENGAGEMENT Baku Metro Expansion Project (BMEP) — Phase II Green Line Extension (AIIB) | Purple Line Extension (ADB) Employer: Baku Metropolitan Closed Joint-Stock Company (Baku Metropolitan) Financing Partners: Asian Infrastructure Investment Bank (AIIB) — Green Line Extension Asian Development Bank (ADB) — Purple Line Extension Date of Event: April 30, 2026, at 10:00 (Baku Time, UTC+4) Format: Virtual Webinar (Microsoft Teams) — link to be provided upon registration 1. Background Baku Metropolitan Closed Joint-Stock Company (Baku Metropolitan), with the support of the Government of the Republic of Azerbaijan, is implementing the Baku Metro Expansion Project (BMEP) — Phase II. This is one of the most significant urban transport investments in the Caucasus region, with a total estimated project value of approximately USD 1.6 billion, financed by AIIB and ADB in parallel. Phase II involves the construction of two new metro lines in Baku, utilizing deep-level Tunnel Boring Machine (TBM) tunnelling through a dense urban environment: • Green Line Extension (AIIB): The Green Line Extension (7.0 km, 4 underground stations: Y-14 to Y-17), to be financed by AIIB — extending metro connectivity to the northwest and central corridors of Baku. • Purple Line Extension (ADB): The Purple Line Extension (8.2 km, 5 underground stations: B-5 to B-8), to be financed by ADB — extending metro connectivity along the east–west corridor, connecting major commercial and residential districts. For prospective bidders, it is important to note the following legacy condition on the Green Line: two TBMs from a prior construction attempt are currently located underground. . Additionally, excavation and construction of two of the stations on the Green Line had started and stopped in 2014, leaving the two stations partly constructed. Furthermore, tunnelling works on the Green Line would potentially come in contact with contaminated soil and ground water. It is also to be noted that the construction INTERNAL.

It may be shared outside ADB with appropriate permission. of two metro lines will exclude signalling and telecommunication systems, which are planned to be implemented under a different project. Site Access, Right-of-Way, and Utilities: Baku Metro is progressing site clearance, right-of-way acquisition, and utility diversion planning in parallel with EME preparation. Market participants are invited to share feedback on what information regarding site access, staging areas, utility interfaces, and surface clearance arrangements they would require at tender stage to prepare credible bids. This topic will be addressed during the webinar Q&A session. Prospective participants should also note that the Green Line alignment (particularly station Y-15) passes through historically industrialized areas where oil-contaminated soils and groundwater may be encountered. Additionally, given the dense urban environment, ground settlement risk to adjacent buildings and utilities is a key technical consideration. The construction methodology will need to address this, including potentially adapted TBM configurations, station drainage systems equipped with contamination monitoring, isolation valves and emergency shutdown protocols, and appropriate treatment and safe disposal of contaminated materials. Station Y-17 is adjacent to residential and commercial buildings on both sides of the station box. Soil-structure interaction at this location has been identified as a key consideration in the design review. Prospective participants should note the relevance of ground settlement risk at station level in addition to the running tunnel alignment. 2. Purpose of This Early Market Engagement This EME is an open, structured, and non-binding market consultation. It is not a formal procurement process, nor does participation constitute pre-qualification or affect any subsequent evaluation. What You Will Gain by Participating • Early, detailed insight into the project scope, scale, and procurement strategy before formal tender launch. • A direct opportunity to shape the procurement approach — your feedback on contract packaging, FIDIC contract form, evaluation criteria, risk allocation, and qualification thresholds will directly inform the final tender documents. • An opportunity to raise project-specific risks — including geotechnical conditions, the Green Line legacy TBM situation, regional logistics, and supply chain constraints — and to provide practical mitigation recommendations. • An opportunity to present your firm's credentials and gauge the scale of the opportunity before committing resources to bid preparation. • Access to both AIIB and ADB procurement staff and Baku Metro's Project Implementation Unit (PIU) in a single session, with the opportunity to ask questions directly. • An opportunity to identify potential joint venture partners, specialist subcontractors, or supply chain collaborators in advance of tendering. 3.
