GENERAL PROCUREMENT NOTICE

Project ID No.: P509952

The Republic of Türkiye has applied for financing in the amount of US$ 2.0 billon equivalent from the World Bank towards the cost of the İstanbul North Rail Crossing Project. This project will be jointly co -financed by the Asian Infrastructure Investment Bank, Asian Development Bank, European Bank of Reconstruction and Development, Islamic Development Bank and OPEC Fund for International Development. The total amount of financing will be US$ 6.75 billion. The Ministry of Transport and Infrastructure, which is the Implementation Agency of the Project, intends to apply part of the proceeds to payments for works, and consulting services to be procured under this project.

The project will include the following components:

Component 1. Design, Infrastructure, and Superstructure Construction Works

This component will finance goods, works and services to deliver the following outputs:

• Preparation of detailed engineering designs for all construction and installation works, which will be conducted under a Design-Build implementation approach (FIDIC Yellow Book). This is expected to improve infrastructure quality outcomes and accelerate physical progress by integrating these interdependent functions under the same provider.
• Construction of 122.3 km of double-track main line connecting the Çayırova and Çatalca stations and 4.7 km of single-track connections to this mainline, totaling 127 km of electrified, fully signalized high-speed railway infrastructure with a top design speed of 160 km/hr.

Component 2. Design Supervision and Construction Supervision Services

This component comprises the provision of consulting services to review all design and supervise construction/installation works under Component 1, including supervision of the procurement process for Design-Build civil works contracts. These services will review design and supervise installation, and construction works across the full length of the project line, i.e. covering all construction phases and contracts.

Component 3. Project Implementation and Oversight Support and Project-level Support to Alleviate Labor Market Gender Gaps

Component 3 will enhance project implementation by mobilizing a Project Management Consultant to provide direct implementation support to Implementing Agency, and by engaging an independent Project Implementation Oversight Consultant to support both Implementing Agency and Project Lenders. In addition, a set of qualified individual consultants will be recruited to complement through targeted, task-specific expertise.

A brief description of the works and consulting services to be procured through open international competitive procurement:

• Works and electrification (Design-Build) of 122.3 km of double-track main line connecting the Çayırova and Çatalca stations and 4.7 km of single-track connections to this mainline,
• Design, supply and installation of signaling, and telecommunication works of the lines
• Consulting services for Project Management to provide direct implementation support to Implementing Agency and capacity building.
• Consulting services for construction supervision of all works contracts
• Consulting services for implementation oversight, including technical support and quality assurance to help meet Implementing Agency and lenders’ requirements.
