Under the contract, Hill will first provide consultancy services for the design, construction, and commissioning of the Athens Metro Line 4. Section A: Alsos Veikou – Goudi of Line 4 will be approximately 12.8 km long and will also include a tunnel connecting Line 4 with Lines 2 and 3, as well as an access tunnel to the train stabling and maintenance yard at Katehaki. Other project features include 15 underground stations and 9 intermediate and/or terminal shafts. Section A of Line 4 is one of the most important in the Athens mass transit system and was designed to serve a number of densely populated areas and several important public buildings and facilities, such as hospitals, educational institutions, courthouses, and public organizations and ministries. Section A of Line 4 project has an estimated cost of €1.5 billion and is scheduled for delivery in 96 months.

The Hill Consortium will also participate in the ongoing Athens Metro Line 3 extension, section Haidari – Piraeus. Construction of the project, which includes a 7.6 km long tunnel, 6 new modern stations, and 7 ventilation intershafts, is well underway. Once complete, the total ridership for the Metro network is expected to increase by 132,000 passengers per day, thus reducing the circulation of private vehicles by 23,000 cars daily and associated carbon dioxide emissions by 120 tons per day. The line will also facilitate travel from Piraeus Port to Athens International Airport in just 55 minutes. With an investment of more than €730 million, the entire Line 3 Extension is expected to be commissioned in summer 2022.
