Metro construction costs in Lisbon
The Violet Line tender, a key part of Lisbon Metro's network expansion plan, is currently under review by an international public tender jury [1]. The tender, launched on April 15, 2025, attracted four proposals, each offering a value between approximately 598.8 million euros and 716 million euros [1].
The Violet Line will span an 11.5-kilometer track, featuring 17 stations across the municipalities of Loures and Odivelas [1]. The stations will have various typologies, with 12 aboveground, three underground, and two in trenches [1].
The tender covers the design and construction of the light metro system, urban reorganization, studies for public utility expropriation, and the supply of vehicles [1]. The project aims for completion by 2029.
The first tender in March 2024 was invalidated due to all bids exceeding the base price by about 46%, leading to an updated higher investment cost by 150.2 million euros [1].
Among the companies that submitted bids, Mota Engil, Engenharia e Construção, S.A./Zagope - Construções e Engenharia, S.A./Spie Batignolles Internacional - Sucursal em Portugal proposed construction for €598.8 million. Another proposal, valued at €716.0 million, was presented by Teixeira Duarte - Engenharia e Construções, S.A./Casais - Engenharia e Construção, S.A./Tecnovia - Sociedade de Empreitadas, S.A./E.P.O.S. - Portuguese Underground Works Company, Inc./Somafel - Railway Engineering and Works, Inc./Jayme da Costa - Energy and Systems, Inc. [1]
The fourth proposal, submitted by the companies FCC Construcción, Inc./Contratas y Ventas, Inc./Comsa, Inc./Comsa Instalaciones Y Sistemas Industriales, Inc./Fergrupo - Technical and Railway Construction, Inc., advanced with a value of €629.9 million [1].
The identities of the companies that submitted the four bids were not specified in the available information. The current status of the tender is that no final decision has been announced yet [1].
In addition to the Violet Line, the Lisbon Metro network is also expanding with the Green Line, which will connect the city centre with the International Airport and the Expo 2020 site. The expansion is expected to improve the public transport system and reduce traffic congestion in the city.
