The world's top 20 contractors 2014 - 10 to 1
10. China Metallurgical Group
The first of five Chinese contractors to make up International Construction's top 10, China Metallurgical Corp is also one of the newest. It was formed in 1982 but is the biggest metallurgical contracting company in the world, with a presence in over 90 countries and a listing on the Hong Kong and Shanghai stock exchanges.
The company builds everything from big, industrial complexes and power plants in its home country to hotels and leisure projects on the island of Guam in the Pacific Ocean to road projects in Bangladesh and the Hassan Sports City stadium complex in Jordan.
Recently, the company's deputy general manager, Zhang Zheying, was expelled from the Communist Party of China after allegations of corruption were made against her. According to the official Xinhua News Agency, the State-owned Assets Supervision and Administration Commission is investigating charges of "serious disciplinary and legal violations", including bribery allegations.
The firm was recently forced to temporarily close a mine in Papua New Guinea, after machinery and workers were attacked by local villagers. It has since reopened and the firm said that it did not expect there to be any financial impact from the stoppage.
Hochtief is based in Essen, Germany and is one of the world's biggest contractors in its own right, but it has also acquired sizeable stakes in other construction firms from around the world. For instance, it now owns Leighton Holdings (13th on this list) and Turner Construction in the US.
Contracting work therefore largely goes through the HLG venture in the Middle East, although Hochtief retains its own construction management arms based in Abu Dhabi and Qatar, as well as its own BIM consulting arm, Hochtief Vicon.
Hochtief's origins dates back to 1874 and includes engineering feats such as the transplantation of the Abu Simbel rock temples in Egypt (saving them from the rise of the River Nile caused by the Aswan High Dam) and infrastructure projects like the new Athens International Airport and Germany's first nuclear power plant.
Subsidiary of the Bouygues group, Bouygues Construction is a global player in the building, civil works, energies and services sectors.
Organised as seven complementary entities, it has proven expertise in financing, designing, constructing, maintaining and operating buildings and structures, offering its customers a vast range of innovative solutions.
In the Middle East, Bouygues recently has focussed its efforts on Qatar, where it is carrying out construction of the new QP district containing Qatar Petroluem's headquarters.
The work is being carried out through its Bouygues Batiment International arm, which specialises in complex construction projects and also has offices in Dubai and Abu Dhabi. The firm also owns post-tensioning specialist VSL, which has carried out lots of bridge and infrastructure projects, as well as a facilities management arm, Ecovert, with operations in the UAE and Kuwait.
Privately-owned, US-based contractor with a major presence right across the region - most notably in Saudi Arabia, where it has been working with the Royal Commission for Jubail and Yanbu on the development of Jubail Industrial City and, more recently, Ras Al Khair Industrial City.
The firm has been operating in the Kingdom for 70 years and is currently working on a number of significant projects, including the Riyadh Metro network, the King Abdullah project for Waad Al Shamaal city development, and the Economic Cities Authority on the development of four new economic cities across the Kingdom (alongside Atkins).
In the UAE it is working up a new masterplan for the expansion of Sharjah airport, while in Qatar the firm recently completed the handover of the Hamad International Airport, which Europe, Middle East and Africa (EMEA) president David Welch recently told CW was a "stunning building of enormous space and character".
"The project has changed in scale, complexity and ambition during its development in order to meet the growing capacity demands," he said.
Worldwide, Bechtel employs 53,000 employees in nearly 40 countries.
Grupo ACS is another major construction company with wide-reaching tentacles. It is not only the parent firm of companies such as contractors ACS and Dragados, it also owns almost half (49.9%) of the eight-biggest company on this list (Hochtief), with sovereign wealth fund Qatar Holding (10%) as a partner.
The company was founded in 1997 through the merger of OCP Construcciones, S.A. and Gines Navarro Construcciones, S.A. and is one of the leading construction companies in the world.
It owns engineering consultant Tecsa, which was part of the FCC consortium that bagged the Riyadh Metro contract, while Dragados last year picked up a $400m contract to build a polyacetel plant in Saudi Arabia.
Indeed, the group now earns around 96% of its overall revenues outside of Spain and in the past 12 months has won an EPC project to install 10 Ethylene Oxide Reactors in different SABIC-affiliated companies in Saudi Arabia, a facility to treat, manage and store naturally-occurring radioactive waste that occcurs during drilling for Abu Dhabi National Oil Company and a deal to build and renovate warehouses in a plant owned by Saudi Arabian Mining Company, Ma'aden.
5. China Communications Construction (CCC), China
China Communications Construction (CCC) is a transport and infrastructure specialist which has grown through activities in ports, dredging and railways, building more than 70 national railway lines including services between Beijing-Shanghai, Lanzhou-Chongqing amd Harbin-Dallan, among others. Within the past year, the firm has seen its backlog of projects double to $120bn.
CCC now operates in 120 countries worldwide and said that 23.4% (%$16.5bn) of its revenues last year came from overseas contracts. Some 12% of this was from the Middle East, where it is running the $611mn East Corridor project in Qatar and the $506mn contract to build a new flood control network in Jeddah, Saudi Arabia.
CCC has more than 30 different business units involved in infrastructure, buildings, dredging, heavy machinery manufacturing and other types of business.
The firm owns ZPMC - the manufacturer of heavy-duty cranes that are now lining more of the Middle East's new container handling terminals, while dredging subsidiaries such as China Harbour Engineering Co and CCC Guangzhou Dredging Company, have picked up major deals in Qatar (at the New Port Project) and Kuwait (Subiya Crossing) successively.

The company has operations throughout the Middle East, where it operates under a number of brands including contractor Freyssinet, environment engineering consultancy DEC, Dredging International, vibro-compaction company Menard and Sainrapt Contracting Co.
It is perhaps best known in the region, though, for its contracting joint venture with state-backed property investor Qatari Diar, QDVC.
It has won two major projects during the first six months of this year. In June, it picked up a $2.7bn (€2bn) project to build the final phase of the Lusail Light Rail Transit network as part of a joint venture with Alstom. The pair are currently delivering an earlier phase of the project, which is due to come into service over a phased period between 2018-2020.
In April, its joint venture with Qatari firm Bin Omran Trading & Contracting won a $1.16bn contract from Qatar's public works authority, Ashghal, to deliver a stretch of the New Orbital Highway and Truck Route under a three-year deal.

The company has generated a significant amount of its revenues from property development projects on land at or close by to new railway projects.
1. China State Construction Engineering Co
The state-backed Chinese construction giant has become the first contractor to earn revenues of more than $100bn.
The firm is also the one contractor to have made significant inroads into the Middle East region.
In Dubai, it built the Shoreline apartments at Palm Jumeirah, where it is also building (and investing in) the new, $1bn Palm Viceroy hotel.
Last month, the contractor announced that it had won contracts to build two further new hotels at Palm Jumeirah
