Ghella is an Italian and international civil engineering company,[1][2] specialized in the construction of large public infrastructural works and underground excavations through the use of tunnel boring machines.[3][4] The company builds rapid transit systems (subways), railways, highways and hydraulic works.[5] Ghella is also active in the renewable energy sector, with photovoltaic and hydroelectric power generation plants. The company has built, in joint venture with Acciona, the first stage of the Mohammed bin Rashid Al Maktoum Solar Park.[6][7] Today Ghella employs more than 3.600 people, lives 14 countries[8] and operates in 4 continents, especially in Europe, the Far East, the Americas and Oceania.[5]
History
The company was founded in 1894 by Domenico Ghella.[9] Before this date, Domenico worked as a miner in France, in the construction of the Suez Canal in Egypt, in the funicular tunnel in Istanbul and to build the Trans-siberian railway.[10] Today, the company is led by the fifth generation of the Ghella family.[9]
Ghella has 150 years of experience and builds, for sustainability and with innovation, through the use advanced technologies and cutting-edge construction methods. Over the years it has built more than 130 tunnels and connected over 1000 km of highways, railways and subways around the world.[8]

Major projects
Completed projects
Legacy Way Project (formerly Northern Link)] - Brisbane, Australia
The Legacy Way Project (2011-2015) is a 4.6 kilometers [1] (2.9 miles) long tunnel in the city of Brisbane connecting the Western Freeway[11] at Toowong and the Inner City Bypass at Kelvin Grove. The work consists of two tolled tunnels [4] inaugurated on 25 June 2015 carrying approximately 20,000 vehicles per day, reducing travel time between the Centenary Bridge and the inner ring road of the city by 71%.
Sydney Metro City & Southwest - Sydney, Australia
The Sydney Metro City & Southwest (2017-2021) consists in the construction of 15.5 km of twin tunnels [12][13] that cross the inlet and a series of new stations on the line towards the City Business District.[14]
Follo Line - Oslo, Norway
The Follo Line is a 22 km high-speed railway line (2015-2022) that links Oslo and Ski,[15] reducing traffic on the outskirts of the capital and halving commuter travel time. It is the longest railway tunnel in Scandinavia.[4][16]
Ongoing projects
Brenner Base Tunnel - Metro of Europe, Italy
The Brenner Base Tunnel project started in 2016 and it is part of the trans-European TEN-T network and it will be the longest underground rail link in the world. It consists of two main tunnels and one of investigation, made with both mechanized and conventional methods and thanks to the use of 3 TBMs. With the 55 km between the Innsbruck portal and the Fortezza portal, the Brenner Base Tunnel will reduce current travel times by 55 minutes, playing a crucial role in European mobility.[17]
Cross River Rail - Brisbane]], Australia
The Cross River Rail project (2019 - ongoing) includes a new 10.2 km underground railway line - of which 5.9 km are under the river - and four new metro stations in the Brisbane Central Business District.[18]
Central Interceptor - Auckland, New Zealand
The Central Interceptor is a large infrastructural project (2019 - ongoing) built fifteen meters below the seabed of Manukau Harbour in central Auckland, where a large tunnel will significantly reduce wastewater overflows due to rain. At 14.7 km, it will be the longest tunnel in New Zealand.[19]
Started in 2020, the Broadway Subway project consists in two 5 km tunnels to extend the Millennium Line in Vancouver[20] and six new stations. Elsie and Phyllis are the names of the two TBMs that are involved in the excavation: both of them are named after two decorated British Columbians who were leaders in engineering.[21][22]
To improve the connection of the southern area of the city, the M6 Stage 1 (2021 - ongoing) foresees the construction of two twin tunnels of 4 km, ramps between the main tunnel and a new surface intersection at President Avenue, a tunnel stub for a future extension of the auxiliary infrastructure, operational structures and new pedestrian and cycle paths.[23]
The work (2021 - ongoing) consists in the executive design and construction of a railway track that develops for approximately 20 km. The contract for the project was awarded to the Joint Venture, by the Italian Rail Network (RFI) in 2021.[24] The Naples–Bari High Speed Railway is an integral part of the European TEN-T Scandinavian-Mediterranean Railway Corridor and it will reinforce the rail network in the south of Italy.
The new metro (2022 - ongoing) consists of 9.8 km of twin rail tunnels in two sections and will offer frequent service and driverless trains as well as six new stations along the alignment between St Marys and Aerotropolis [25]
Turin-Lyon Lot 1 Saint Jean de Maurienne AV - France
The Turin-Lyon (2022 - ongoing) is a new railway line that extends for 270 km: 70% in France and 30% in Italy. It is the central part of the Mediterranean Corridor, one of the 9 axes of the TEN-T network. The 65 km cross-border section between Italy and France constitutes the central part of the project[26]
Sydney Metro West - Eastern Tunneling Package - Australia
This project is the final major tunneling package of the city-shaping Sydney Metro West project. Two TBMs will excavate 3.5 km of metro rail tunnels from The Bays to Sydney's Central Business District.[27][28] This work also includes the dig of caverns and shafts at Pyrmont and Hunter Street [29]
Other activities
The company is involved as partner in the promotion of cultural projects. During the pandemic period, Ghella supported the exhibit and catalog INSIEME, a project conceived by Gianni Politi and promoted by Roma Capitale, Sovrintendenza Capitolina ai Beni Culturali. The exhibit was realized inside the Aurelian Walls to display the works of 19 artists and build a dialogue between monument and contemporary[30]
In 2021, Ghella commissioned a series of photographic campaigns on construction sites in Europe, the Far East and Oceania. The works were collected in the catalog “Di roccia, fuochi e avventure sotterranee” curated by Alessandro Dandini de Sylva [31] and displayed in an exhibit at the MAXXI museum in Rome.
