An international consortium led by US-headquartered Hill International has been awarded a contract by Attiko Metro SA to provide technical consultancy services for metro and tram projects in the Attica Region of Greece, comprising greater Athens.
Hill will first provide consultancy services for the design, construction, and commissioning of the Athens Metro Line 4. Section A of that line, from Alsos Veikou to Goudi, will be 12.8km long with 15 stations 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.
Estimated to cost €1.5bn, Section A of Line 4 is considered one of the most important transport projects in the Athens, Hill said, as it will serve densely populated areas with health, education and public administration centres. The section is scheduled for delivery in 96 months.
The Hill Consortium will also participate in the ongoing Athens Metro Line 3 extension from Haidari to Piraeus. Work includes a 7.6km tunnel, six stations and seven ventilation shafts.
Costing around €730m, the entire Line 3 extension is expected to be commissioned this summer (2022), and will shorten the journey between Piraeus Port and Athens International Airport to 55 minutes.
The extensions are intended to increase total ridership on the Metro network by 132,000 passengers a day, taking the equivalent of 23,000 cars off the road daily.
Manolis Sigalas, Hill’s Southern Europe managing director, said the extensions were “of profound significance for the city of Athens and one of the largest infrastructure programs currently underway in Europe”.
