Line C:

The project for Line C of the Rome Metro, the third line envisaged by the Town General Plan, aims to directly connect currently distant areas and neighbourhoods by crossing the city from northwest to southeast. Once completed, Line C will increase the development of the existing metro network by more than 50%.

The "Fundamental Route" of Line C, extended over a length of 25.5 km and equipped with 29 stations, begins on the surface in the territory of the Municipality of Monte Compatri and follows the route of the existing Termini-Pantano railway. Subsequently, it descends underground just before the Grande Raccordo Anulare, crossing the historic centre to the Mazzini neighbourhood. Along its route, Line C intersects Line A (San Giovanni and Ottaviano), Line B (Colosseo), the future Line D (Venezia) creating an effective "network effect".

The route, now fully funded, is divided into sections whose construction began with those further east: T2 under design, T3 under construction, T4-T5, T6 and T7 with the Granite Depot/Workshop, completed and operational. The subdivision of the Fundamental Route into sections derives from the different progress state of the designs at the time of the inclusion of the work in the Objective Law (2003), with the consequent approval and financing procedures. 

The route of the T3 Section, which falls entirely within a historical-monumental context unique in the world, develops for a total length of about 3 km from Piazzale Appio to Via dei Fori Imperiali. The project includes 2 stations, Porta Metronia and Colosseo/Fori Imperiali, two multifunctional shafts, respectively in the gardens of Via Sannio and Piazza Celimontana, and 2 line tunnels of 5.8 m in diameter each, almost entirely made with TBM.

The part of Section T3, which includes the line tunnels from San Giovanni to Via Sannio (built using the traditional method), the multifunctional shaft in Via Sannio, and the section of the line tunnels to Porta Metronia Station (built using mechanised excavation through TBM), has already been delivered to the Administration with minutes of advance delivery art. 200 Presidential Decree 554/99 dated 18/06/2021, and was then subject to the authorisation for operation by Lazio Region Decree No. G10991 dated 11/08/2022. The early completion of this part made it available to the Merchant a railway communication (at the multifunctional shaft) through which the reversal of the trains upstream of the current provisional terminus of San Giovanni can take place, thus allowing the use of both station platforms.

At the moment, the construction of the remaining part of the Section is being completed, with the two stations and the Celimontana shaft: the civil works are substantially completed and progress is being made with the architectural finishes and the plant part, both station and line. As of 31/12/2023 (SAL 63 as of 31/08/2023) there is a total accounted amount of € 583,118,525.58 plus VAT, which represents about 86% of the total contractual amount (€ 676,601,467.92 plus VAT). The net amount accounted for the works only is € 492,322,455.73 plus VAT, corresponding to about 89% of the total reference amount from the updated Economic Framework, which amounts to € 553,539,226.11 plus VAT.

In particular, the value of the works of the stations with respect to the total works (about 550 million euros) amounts to: about 90 million for the Porta Metronia station, 120 for the Colosseo/Fori Imperiali station, 200 for the line tunnels, 80 for the plants, and 60 for the remaining items (shafts, special works and more).

Colosseo/Fori Imperiali Station:

The Colosseo/Fori Imperiali station of Line C of the Rome metro extends below Via dei Fori Imperiali, positioning itself between the Colosseum and the area in front of the Basilica of Maxentius. This station will be equipped with two distinct entrances: one on the Clivo di Acilio side and the other on the Clivo di Venere Felice side, thus allowing an interchange with Line B.

The Colosseo/Fori Imperiali station will provide access to the platforms of the Colosseo station of Line B via a direct underground link, part of which will overpass the tunnel of the Colosseo station of Line B and enter the Colosseum Shaft (Pozzo Colosseo). This new structure, made with the top-down method between reinforced concrete diaphragms, extends for about 240 metres, with a width ranging from 30 to 60 metres and a depth of 32 metres from the street level, divided into five levels.

The area where the station is located is of considerable historical importance, being next to the Flavian Amphitheatre, the Basilica of Maxentius, the Temple of Venus and Rome, and the areas of Villa Rivaldi. The construction of the station involved the ancient hill of Velia, largely removed for the construction of the Via dei Fori Imperiali in 1932, bringing to light several archaeological structures.

Although these excavations have compromised much of the archaeological pre-existence underground, archaeological investigations and excavations of the station and the Colosseum Shaft (Pozzo Colosseo) have brought to light, among other things, "archaic" shafts for the collection of groundwater, parts of buildings of the late Republican and early imperial ages, remains of a large circular structure (probably a fountain) and a rectangular basin with marble coating attributable to the Flavian era. In addition, on the Clivo di Acilio and Villa Rivaldi side, the stratigraphy and structures saved by the cutting of the Velia and preserved behind the containing wall of Antonio Muñoz, pertinent to the imperial age residential buildings of the southeastern slope of the hill, were exhibited. Below the filling levels of the early modern age, the remains of an articulated complex of structures dating from the early imperial age to late antiquity emerged.

The project of the station includes two variants during construction due to archaeological findings: one concerning the exhibition arrangement and the other the Clivo Acilio side. The first consists in the relocation of the archaeological findings discovered during the excavations inside the station, with display cases and dedicated routes, while the second involves the relocation of the ancient walls found along the Clivo di Acilio, under the responsibility of the Archaeological Park of the Colosseum.

In summary, the museum spaces of the station will be organised into five areas: transformations of the area of the Imperial Forums, shafts from the archaic era, the ancient landscape of the Velia, ritual shafts, and a "Forum" of the station.

RFI is currently carrying out a project aimed at opening the second front of the Trastevere station. The intervention in question is conceived as a preliminary phase of a larger project, which involves the construction of a second station front equipped with a hypogeal square and a linear park. The initial phase of the work includes the following activities:

• Reopening and extension of the second sub-step of the station up to the fourth sidewalk: the reopening and extension of the second sub-step of the station is planned in order to improve its accessibility and usability.
• Construction of a driveway and pedestrian entrance from Via del Fornetto: A new driveway and pedestrian entrance will be built from Via del Fornetto to facilitate access to the station and facilitate intermodal exchange.
• Redevelopment of the existing staircase on Via Portuense: We will proceed with the redevelopment of the existing staircase on Via Portuense in order to allow further access to the station and improve the user experience.

This design configuration is designed to provide a significant improvement to the Trastevere station in view of the Jubilee, anticipating and preparing the infrastructure for the increase in passenger flow expected on the occasion of the event.

The redevelopment of the Roma Aurelia station is part of the interventions aimed at improving services in railway stations in view of the 2025 Jubilee, with the aim of enhancing the accessibility, safety and decorum of stationary environments. The intervention on the station is closely related to the transformation of the current parking spaces of the buses in front of the station into a bus terminal, with the aim of facilitating the intermodal iron-rubber exchange in view of the jubilee events. An increase in user turnout is expected as a result of this transformation. Therefore, during the jubilee period the following interventions are planned:

• Interventions on the Traveller Building: it is planned to expand the spaces at the service of travellers through the reconversion of the premises currently in disuse into areas intended for parking and waiting for passengers. New toilets will also be built to improve user comfort. In addition, the connection with the station underpass will be restored, in order to ensure easy and safe access for passengers.

In view of the upcoming Jubilee, a preliminary phase of interventions on the Tuscolana station system is planned, which will mainly focus on specific interventions and maintenance. The planned activities will include:

• Refunctionalisation of the internal spaces of the Traveller Building: the internal spaces of the Traveller Building are expected to be adapted to improve their functionality.
• Cleaning of internal and external surfaces: cleaning operations will be carried out on the internal and external surfaces of the Via Adria Building, the underpasses and the Accessory Building, in order to guarantee a more welcoming and cared-for environment for travellers.
• Restoration of sidewalk shelters 2-3-4: The shelters on sidewalk 2-3-4 will be restored in order to improve protection from atmospheric agents and ensure greater comfort for passengers while waiting.

The main objective of these interventions is to preserve and improve the conditions of the Tuscolana station system, ensuring a clean, functional and welcoming environment for passengers and visitors.

In view of the upcoming Jubilee, a preliminary phase of interventions on the station system is planned, which places us inside the Archaeological Park of the Appia Antica. The interventions aim at the redevelopment of the existing passenger building, the adaptation of accessibility and the arrangement of the external station areas belonging to the railway territory. The planned activities include in particular:

• Transformation of the current premises of the building into reception spaces: the current premises of the building will be reconverted into welcoming spaces for passengers and visitors, ensuring a comfortable and functional environment.
• Improvement of parking routes and waiting areas on the sidewalks: interventions will be carried out aimed at improving parking routes and waiting areas on the sidewalks, ensuring a better organisation of the space.
• Reorganisation of the parking and rest areas of the TPL service: we will proceed with the reorganisation of the parking and rest areas of the local public transport service (TPL), in order to optimise the use of the available space and improve the efficiency of the service.

The main objective of these interventions is to improve the overall experience of passengers and visitors to the station, making it more welcoming, accessible and functional.

Improvements and expansion of the Val Cannuta Nursery School, located in the territory of Municipality III, are planned.

The building currently houses a nursery school, and the intervention activities will aim to expand it to make it accessible to a greater number of children.

The objective is therefore to reorganise the existing premises to increase the capacity of the building, paying particular attention to structural safety and energy efficiency of the structure. 

Project objectives will include:

• the increase in the current surface area (from 960 sqm to 1,160 sqm);
• the increase of the seismic safety index to 0.815;
• the improvement of the energy class up to letter D;
• fire-fighting adaptation.

The completion process of the Porta di Roma neighbourhood, which was interrupted in 2018 due to an urban planning agreement, has been restarted. The program includes various activities, including the construction of new housing units, in addition to various interventions for the restoration and completion of the well-known Parco delle Sabine. There will also be a kindergarten, which can accommodate up to 60 children, a nursery school with three sections, a senior centre with bowls club and a green area with sports equipment.

Among the other projects included, there will be the creation of a cycle path that will connect Porta di Roma to the Parco delle Sabine, in combination with new equipped naturalistic and archaeological routes. Extraordinary maintenance works to restore the road network and related infrastructure are already underway.

The Space Smart Factory project is aimed to build an advanced, digitised and highly flexible factory, ranking among the greatest in Europe. This factory will be included into a system of interconnected space factories, located in different Italian cities. The Space Smart Factory will use state-of-the-art technologies to produce satellites of several classes and for several fields of application.

The Space Smart Factory initiative is the results of an investment of more than EUR 100 million, and also involves the Italian Space Agency (ASI) through the funds included in Italy's National Recovery and Resilience Plan (NRRP). Leonardo Global Solutions supported the whole building project, from land acquisition, through tender management, to the launch of the construction work. The preliminary activities and the executive design of the buildings started at the end of September, with the aim of having the factory operational by mid-2025.

The Space Smart Factory will implement process automation and digitisation systems to ensure a high production capacity of the next-generation space assets. Special attention will be given to the micro and small satellite segment, including the PLATINO and Nimbus projects, satellite constellations and Thales Alenia Space's modular platforms for commercial and institutional programs.

Through the use of modular clean rooms and digital technologies, the Space Smart Factory will be able to adapt to the required production needs, enabling the integration and testing of a wide range of satellites of various classes and space applications, such as those dedicated to Earth Observation, Navigation and Telecommunications.

The centre will be a digital hub using state-of-the-art technologies such as numerical modelling, Digital Twins, virtual and augmented reality, integrated simulators and highly automated systems. Moreover, it will host the Space Joint Lab, a space for innovation and collaboration, designed to the training of new professionals in the space industry and the development of innovative ideas and products in partnership with SMEs, start-ups, vendors, industrial partners and research centres.

The entire project will be inspired by the principles of sustainable architecture, with a focus on energy saving and the efficient use of renewable energy through the adoption of new digital technologies.

The new "Hyper Cloud Data Center" will be set up by Aruba in the Tiburtino Technopole. The campus, designed specifically for the data centre over an area of 74 thousand square meters, will comply with the highest standards of resilience and infrastructure quality. Upon completion it will be certified, like IT1 and IT3 standards, with a Rating 4 compliant to standards ANSI/TIA 942-A. In addition of being connected with the major Internet networks, it will have multiple interconnections with the campuses located in Arezzo (IT1 e IT2) and with the Global Cloud Data Center (IT3).

The main goal of the Hyper Cloud Data Center is to become the main reference point for data centre services and solutions - both physical and cloud-based - designed for businesses, Public Administration, Local Bodies, as well as for banking and finance. The Hyper Cloud Data Center in Rome will provide business continuity and disaster recovery solutions for Enterprises and Public Administration.

This project is also of particular importance form an environmental point of view, as it includes a fully sustainable Data Centre. It will be powered exclusively by renewable energy, certified at European level through the Guarantee of Origin (GO), thus minimising the environmental impact and ensuring greater sustainability in its operation.

A new Urban Transformation Program called "Cecchignola Ovest" has been launched in Municipality IX. The intervention will include various activities, among which the construction of private buildings, roads, car parks and public sewage systems. 

Furthermore, there will be included the construction of a park of approximately 22 hectares and new public services, including two kindergartens for 60 children, two nursery schools with three sections each and an elementary school with 10 classrooms.

Private construction, amounting to approximately 425,000 cubic metres, is currently underway. Some buildings, known as "Città Verde” (Green City), are following the certification program according to the GBC Quartieri energy-environmental protocol, respecting the criteria of the GBC Home protocol. This approach aims to encourage socialization and cultural exchange, helping to give the new neighbourhood its own urban identity.
