20 Largest Construction Companies in the World: Powerful Leaders Driving Growth

Twenty companies now generate a combined USD 20 trillion in annual construction revenue, led by China State Construction Engineering Corporation at approximately USD 300 billion. Chinese state-owned enterprises hold five of the top six positions, while European and North American groups compete in data centres, energy transition, and semiconductors. This ranking draws on the latest audited annual reports, ENR’s 2026 Top 400 Contractors list, and company investor disclosures.

Technical Snapshot: Global Construction Industry Leaders

Scale alone no longer decides who leads construction. Backlog quality, data centre exposure, and international diversification now set the world’s largest construction companies apart from firms simply chasing volume.

Introduction: World’s Largest Construction Companies

The world’s biggest construction companies sit at the centre of a market reshaping itself around artificial intelligence infrastructure, energy transition, and government-backed rebuilding programmes. Total revenue across ENR’s Top 400 contractors climbed 11.8% to USD 671.4 billion in 2025, and the gains are not evenly spread. A handful of state-owned Chinese conglomerates, French concessions groups, and American data centre specialists now capture a disproportionate share of new contract value.

This pillar ranks the top global construction firms by their most recently reported annual revenue, then breaks the field down by region, ownership structure, and specialism. It complements a broader look at the consolidation and M&A strategies reshaping the sector, which examines how firms on this list grow through acquisition rather than organic contract wins alone. This global view also serves as the starting point for a deeper dive into any single market: every regional and country-level ranking referenced below expands on how these global leaders, and the local contractors competing against them, stack up in that specific market.

Company size on this list reflects contracting revenue, not necessarily project quality, safety record, or client satisfaction. A firm ranked fourth among the world’s biggest construction companies may still lose ground in a specific country to a leaner, better-connected regional contractor. Readers using this ranking of the largest construction companies in the world to benchmark suppliers, evaluate joint venture partners, or assess market entry should treat revenue as one input among several, alongside backlog composition and geographic exposure, which are covered later in this article.

Methodology: How These Rankings Are Built

This is a list of top construction companies ranked by revenue rather than by profitability, safety record, or backlog size. Readers comparing the largest EPC companies globally ranked here against sector-specific lists should expect some divergence. Revenue figures come from each company’s most recently published annual report, investor disclosure, or regulatory filing, and are cross-checked against ENR’s 2026 Top 400 Contractors list and Fortune Global 500 data, where available.

Fiscal years vary: most Chinese state-owned enterprises report on a calendar-year basis with a reporting lag, while some companies, including Larsen & Toubro, report on an April-to-March cycle. Currency conversions to US dollars use approximate rates at the time of each company’s results release, so figures should be read as directional rather than exact.

Subsidiaries owned by a parent already on this list, such as Turner Construction under HOCHTIEF and ACS, or CIMIC under HOCHTIEF, are counted separately because each reports revenue independently and competes for contracts under its own brand. Group-level revenue for diversified conglomerates like Bouygues includes non-construction divisions such as telecommunications and media, which inflates the group figure relative to pure-play contractors. Where a construction-specific segment figure was available, this ranking uses it instead of total group revenue.

The table below lists the top global construction firms ranked by most recently reported annual revenue, along with their headquarters, workforce, and core specialism.

Ranking Criteria for Kenya’s Largest Construction Companies

China’s State-Backed Construction Giants

Five Chinese state-owned enterprises top this ranking, reflecting decades of domestic infrastructure spending combined with an aggressive push into Belt and Road markets. All five trade at a discount to their Western peers on international investor markets, largely because state ownership and thin backlog reporting make their forward pipelines harder to verify.

1. China State Construction Engineering Corporation (CSCEC)

• Founded: 1982, building on a predecessor construction bureau established in 1957
• Website: cscec.com
• Founders: Established directly by the State Council of China, with no individual founders
• Ownership today: Wholly state-owned, supervised by SASAC
• 2025 Revenue: ~USD 300 billion
• Workforce: 300,000+
• Major projects: Shanghai Tower; Beijing Daxing International Airport; New Administrative Capital towers, Egypt

China State Construction Engineering Corporation remains the largest construction company in the world by a wide margin, having built more than 90% of China’s skyscrapers above 300 metres. The group is targeting 50% overseas revenue by 2030, a shift that would fundamentally rebalance a currently domestic-heavy revenue base.

2. China Railway Construction Corporation (CRCC)

• Founded: Traces to the People’s Liberation Army Railway Engineering Corps of 1948; incorporated as CRCC Limited in 2007
• Website: crcc.cn 
• Founders: Established through military-to-civilian reorganisation under the Chinese state, with no individual founders
• Ownership today: Wholly state-owned, supervised by SASAC
• 2025 Revenue: ~USD 161 billion
• Workforce: 336,000+
• Major projects: Mecca-Medina Haramain High-Speed Railway, Saudi Arabia; Mombasa-Nairobi Standard Gauge Railway, Kenya; Lagos-Ibadan Railway, Nigeria

China Railway Construction Corporation ranks second globally by revenue and has built roughly two-thirds of China’s rail network over the past three decades. It now exports that expertise across Southeast Asia and the Middle East, competing for the same high-speed rail contracts that Western engineering firms increasingly avoid on price.

3. China Railway Group (CREC)

• Founded: Traces to 1950 predecessor units under the Ministry of Railways; listed as China Railway Group Limited in 2007
• Website: crecg.com 
• Founders: Established through state railway-sector reorganisation, with no individual founders
• Ownership today: Majority state-owned via the State Council, with a Hong Kong and Shanghai-listed arm
• 2025 Revenue: ~USD 110 billion
• Workforce: 282,000+
• Major projects: China-Laos Railway; Addis Ababa-Djibouti Railway, Ethiopia; Karakoram Highway upgrade, Pakistan

China Railway Group shares CRCC’s rail heritage but has pushed harder into overseas markets, including Africa and Central Asia, work that overlaps directly with the contractors covered in Chinese firms expanding across Africa. Domestically, it remains one of the two dominant bidders on any major Chinese rail tender.

• 2025 Revenue: ~USD 101 billion
• Workforce: 134,000+
• Major projects: Hong Kong-Zhuhai-Macau Bridge; Colombo Port City, Sri Lanka; Lekki Deep Sea Port, Nigeria

China Communications Construction Company dominates port, dredging, and marine infrastructure through subsidiaries, including China Harbour Engineering, giving it a footprint in coastal and island construction that none of its domestic peers can match. Its marine dredging fleet is widely regarded as the largest of its kind globally.

5. Power Construction Corporation of China (POWERCHINA)

• Founded: 2011, through the merger of Sinohydro, HydroChina, and provincial power engineering units
• Website: en.powerchina.cn 
• Founders: Established by State Council approval, with no individual founders

• 2025 Revenue: ~USD 97 billion
• Workforce: 184,500+
• Major projects: Karot Hydropower Station, Pakistan; Merowe Dam, Sudan; Julius Nyerere Hydropower Station, Tanzania

POWERCHINA has built more than 65% of the country’s large and medium hydropower stations and now applies that expertise to wind, solar, and grid infrastructure abroad. Its energy focus sets it apart from the other four Chinese giants, which lean more heavily toward buildings, rail, and marine work.

Europe’s Engineering and Infrastructure Leaders

European contractors compete less on raw scale and more on concessions, energy transition, and defence-linked infrastructure, a strategy that trades headline revenue for steadier, higher-margin income.

6. VINCI SA

• Website: vinci.com 
• Founders: Alexandre Giros and Louis Loucheur
• Ownership today: Publicly listed on Euronext Paris, widely held with no controlling shareholder
• 2025 Revenue: ~USD 81 billion (€74.6 billion)
• Workforce: 280,000+
• Major projects: Grand Paris Express; global airport concessions network including Gatwick and Belgrade; Lusail Expressway, Qatar

VINCI posted €74.6 billion in FY2025 revenue, up 4% year on year, and now operates the world’s largest private airport network alongside an 8,200-kilometre motorway concession portfolio. That concession base gives it a recurring revenue stream that pure contractors on this list lack.

7. Bouygues Group

• Founded: 1952
• Website: bouygues-construction.com 
• Founders: Francis Bouygues
• Ownership today: Family-controlled through the Bouygues family’s SCDM holding, chaired by Martin Bouygues
• 2025 Revenue: ~USD 61 billion (€56 billion)
• Workforce: 200,000+
• Major projects: Channel Tunnel (as part of the TransManche Link consortium); Stade de France; Flamanville EPR nuclear reactor

Bouygues blends construction with telecommunications, media, and energy services under one group structure, which inflates its headline revenue relative to pure-play contractors but also insulates it from any single sector’s downturn.

8. Grupo ACS

• Founded: 1997, through the merger of OCP Construcciones and Ginés Navarro Construcciones
• Website: grupoacs.com 
• Founders: Florentino Pérez led the founding team of engineers behind the merger
• Ownership today: Publicly listed on the Bolsa de Madrid; Florentino Pérez holds the largest individual stake, alongside CriteriaCaixa
• 2025 Revenue: ~USD 54 billion (€49.9 billion)
• Workforce: 135,000+
• Major projects: I-4 Ultimate highway upgrade, Florida; extensive North American toll-road P3 portfolio via Flatiron Dragados; European rail concessions

Grupo ACS reported a record €92.9 billion backlog in FY2025, driven heavily by its Turner and HOCHTIEF subsidiaries, giving it close to two years of secured work at current revenue levels.

9. HOCHTIEF AG

• Founded: 1873, as Gebrüder Helfmann
• Website: hochtief.com  
• Founders: Philipp and Balthasar Helfmann
• Ownership today: Majority owned by Grupo ACS, which holds close to 80%
• 2025 Revenue: ~USD 42.3 billion
• Workforce: 53,000+
• Major projects: Elbphilharmonie, Hamburg; West Gate Tunnel, Melbourne (via CIMIC); hyperscale data centre developments across Europe and the Americas

HOCHTIEF entered Germany’s DAX index in 2026 on the strength of €16.8 billion in new data centre orders, a move that rewarded its backlog quality over its comparatively modest revenue rank.

10. Eiffage SA

• Founded: 1993, through the merger of Fougerolle and SAE, with roots tracing to Fougerolle’s 1844 origins
• Website: eiffage.com 
• Founders: Formed by a corporate merger rather than a single founder
• Ownership today: No controlling shareholder; employees collectively hold one of the largest blocks of shares of any CAC 40 company
• 2025 Revenue: ~USD 24 billion (€22 billion)
• Workforce: 100,000+
• Major projects: Millau Viaduct; multiple Grand Paris Express lots; French motorway concessions network

Eiffage mirrors VINCI’s model on a smaller scale, blending construction with energy services and public-private partnerships to build recurring concession income that a pure contractor cannot access.

11. Ferrovial SE

• Founded: 1952
• Website: ferrovial.com 
• Founders: Rafael del Pino y Moreno
• Ownership today: Publicly listed with the del Pino family as the largest single shareholder bloc
• 2025 Revenue: ~USD 22 billion (€20 billion)
• Workforce: 68,000+
• Major projects: 407 ETR toll road, Toronto; I-77 Express Lanes, North Carolina; former stake in Heathrow Airport

Ferrovial, having relocated its listing to Amsterdam and then to the United States, now weights its portfolio toward toll roads and airports rather than traditional contracting, a deliberate shift away from lower-margin construction revenue.

12. STRABAG SE

• Founded: 1835, tracing to the Austrian craftsman’s business that became ILBAU, with its German STRABAG arm dating to 1895
• Website: strabag.com 
• Founders: Anton Lerchbaumer founded the Austrian ILBAU predecessor
• Ownership today: A shareholder syndicate led by the Haselsteiner family alongside Raiffeisen and UNIQA
• 2025 Revenue: ~USD 19.5 billion (€18 billion)
• Workforce: 86,000+
• Major projects: Semmering Base Tunnel, Austria; multiple EU-funded Central and Eastern European motorway programmes

STRABAG leads in tunnelling and transport infrastructure across Central and Eastern Europe, a regional specialism that has made it the contractor of choice for EU-funded rail and motorway programmes.

13. Skanska AB

• Founded: 1887, as Skånska Cementgjuteriet
• Website: skanska.com 
• Founders: Rudolf Fredrik Berg
• Ownership today: Publicly listed on Nasdaq Stockholm, widely held with no controlling owner
• 2025 Revenue: ~USD 16 billion
• Workforce: 27,000+
• Major projects: Mario M. Cuomo Bridge, New York; multiple US hyperscale data centre builds; UK hospital construction programmes

Skanska closes out the European tier with record construction-segment operating income in FY2025, built on a sustainability-led client base across the Nordics, UK, and the United States.

North American and Asia-Pacific Contenders

American contractors have grown fastest on the back of data centre and semiconductor construction, a shift that has pulled revenue away from traditional commercial and civil work.

14. Turner Construction Company

• Founded: 1902
• Website: turnerconstruction.com 
• Founders: Henry C. Turner
• Ownership today: Wholly owned subsidiary of HOCHTIEF, itself majority owned by Grupo ACS
• 2025 Revenue: ~USD 29.2 billion
• Workforce: 12,000+
• Major projects: Multiple hyperscale data centre campuses across the United States; healthcare and sports facility construction nationwide

Turner Construction reported record 2025 revenue of USD 29.2 billion, up 40% year on year, with a USD 44.3 billion backlog in which data centres account for roughly 37%, the clearest evidence on this list of how thoroughly AI infrastructure has reshaped contractor priorities.

15. Bechtel Corporation

• Founded: 1898
• Website: bechtel.com 
• Founders: Warren A. Bechtel
• Ownership today: Privately held, controlled by the Bechtel family across five generations, currently chaired by Brendan Bechtel
• 2025 Revenue: ~USD 19.5 billion
• Workforce: 55,000+

Bechtel, the largest privately held engineering and construction firm globally, grew its 2025 revenue to USD 19.5 billion while delivering semiconductor fabrication plants for TSMC and Intel through its Manufacturing and Technology business unit.

16. AECOM

• Founded: 1990 as a management buyout of Ashland Oil’s engineering and construction units
• Website: aecom.com 
• Founders: Formed by a group of senior managers rather than a single founder
• Ownership today: Publicly listed on the NYSE, widely held with no controlling shareholder
• 2025 Revenue: ~USD 22 billion
• Workforce: 52,000+
• Major projects: London 2012 Olympic Park infrastructure; HS2 high-speed rail programme, United Kingdom

AECOM leans toward consulting, programme management, and government infrastructure work rather than direct contracting, a positioning that produces higher margins but lower headline revenue than the pure builders above it.

17. Jacobs Solutions

• Founded: 1947
• Website: jacobs.com 
• Founders: Joseph J. Jacobs
• Ownership today: Publicly listed on the NYSE, widely held with no controlling shareholder
• 2025 Revenue: ~USD 16 billion
• Workforce: 60,000+
• Major projects: HS2 design and engineering services, United Kingdom; long-running NASA space programme engineering support

Jacobs Solutions follows a similar advisory-led model to AECOM, generating revenue from technical and professional services rather than construction execution, which keeps its headcount lean relative to its revenue.

18. Fluor Corporation

• Founded: 1912
• Website: fluor.com 
• Founders: John Simon Fluor Sr.
• Ownership today: Publicly listed on the NYSE, widely held with no controlling shareholder
• 2025 Revenue: ~USD 15.5 billion
• Workforce: 23,000+
• Major projects: Gorgon LNG facility, Australia; Canadian oil sands processing plants

Fluor has narrowed its focus to energy, mining, and advanced technologies EPC work after several years of deliberate workforce reduction, reporting USD 15.5 billion in 2025 revenue against a leaner 23,000-person headcount.

Emerging Global Players to Watch

Two firms outside the traditional China-Europe-America axis complete this ranking and illustrate where the next wave of growth is concentrated.

19. Larsen & Toubro

• Founded: 1938
• Website: lntecc.com 
• Founders: Henning Holck-Larsen and Søren Kristian Toubro
• Ownership today: Publicly listed and professionally managed, with no promoter family; Life Insurance Corporation of India is the largest institutional shareholder
• 2025 Revenue: ~USD 33.8 billion
• Workforce: 100,000+
• Major projects: Statue of Unity, India; Mumbai Trans Harbour Link; multiple Gulf Cooperation Council infrastructure contracts

Larsen & Toubro posted a record ₹7.40 lakh crore order book for FY2025-26, with international orders now accounting for 52% of the total as the company expands aggressively into Gulf Cooperation Council markets alongside its dominant position in India’s own infrastructure cycle.

20. Samsung C&T Engineering & Construction Group

• Founded: 1938 as Samsung Trading, with its construction arm established in 1975
• Website: samsungcnt.com 
• Founders: Lee Byung-chul founded Samsung; the construction division grew out of the wider Samsung Group
• Ownership today: Part of Samsung Group, controlled through the Lee family’s cross-shareholding structure
• 2025 Revenue: ~USD 15 billion
• Workforce: 9,000+ (E&C division)
• Major projects: Burj Khalifa, Dubai; Petronas Towers (Tower 2), Kuala Lumpur; THE LINE infrastructure, NEOM, Saudi Arabia

Samsung C&T’s Engineering & Construction Group has built a specialised niche in semiconductor fabrication plants and Middle East mega-projects, including signature developments tied to Saudi Arabia’s NEOM programme, giving it outsized influence relative to its headline revenue figure.

What Separates the Top Tier from the Rest

Comparing the biggest construction firms in China against Europe’s leaders shows why revenue rank alone understates the gap between the five Chinese state-owned giants and everyone else on this list. The five Chinese firms generate a combined USD 769 billion, well over half of the entire Top 20’s USD 1.24 trillion, largely through domestic infrastructure spending that dwarfs any single Western national programme. Backlog transparency and international revenue share, however, tell a different story, and this is where the next tier of contractors closes the gap.

Comparison: Top-Tier Chinese SOEs vs the Rest of the Top 20

The practical takeaway for investors, joint venture partners, and project owners is that backlog quality and disclosed pipeline visibility now matter more than raw revenue rank when assessing which of the largest engineering and construction firms globally can actually deliver on a specific contract. A contractor ranked 15th among the world’s largest infrastructure contractors with a fully disclosed, diversified backlog may represent a safer counterparty than one ranked 4th with opaque domestic exposure. Anyone asking who the largest construction companies in the world actually are, by delivery certainty rather than headline revenue, should weigh this backlog data as heavily as the rankings themselves.

Regional Rankings: Explore Every Market

Global rankings only tell part of the story, because construction remains fundamentally a local delivery business even when the parent group operates across dozens of countries. This section serves as the index for that local view, gathering every regional and country ranking that Construction Frontier has published, each built on the same revenue-first methodology used for this global list.

Africa: Continental and Country-Level Rankings

Step outside the top 20 and the geography changes fast. Nowhere is that more visible than in Africa, where state-backed multinationals still win the biggest contracts, but a growing set of local and regional contractors is closing the gap fast enough to earn their own ranking, tracked continent-wide among the 25 largest construction companies in Africa.

Nigeria

Nigeria is a good example of how quickly that balance can shift. Chinese-backed contractors have moved in aggressively over the past decade, yet legacy names like Julius Berger still hold their ground against the newcomers, a competitive picture laid out in full in the profiles of the 15 largest construction companies in Nigeria.

Egypt

Egypt runs on a different logic again. State-linked firms and foreign joint ventures dominate the market there, with Arab Contractors and Petrojet still anchoring domestic delivery decades after their founding. See the 12 largest construction companies in Egypt for the full breakdown.

South Africa 

South Africa’s ranking barely resembles the one this cluster would have shown a year ago. Murray & Roberts entered liquidation in January 2026, and that single event reshuffled the country’s entire competitive order, a shift covered in depth in the 15 largest construction companies in South Africa.

Morocco

Morocco takes a different path again, having grown a genuinely homegrown cluster of contractors that now wins regional infrastructure work well beyond its own borders. That cluster, alongside a growing pipeline of foreign-backed rail and port projects, is profiled in the 10 largest construction companies in Morocco.

Kenya

Kenya remains East Africa’s most closely watched market, where public infrastructure spending has kept growth steady even as fiscal conditions have tightened elsewhere in the region. That dynamic is explored fully in the ranking of Kenya’s top 20 construction companies.

Asia’s Construction Giants

Asia barely needs an introduction on this list, since five of its companies already sit inside the global top 20. What that world ranking can’t show is how Japanese and South Korean contractors compete against those same Chinese state-owned firms on their own turf, which is exactly the gap the 20 largest construction companies in Asia set out to close.

North America and Europe

The United States remains the largest single-national construction market in the world by output, and its leading firms look nothing like the global top five. Turner, Bechtel, and the rest of the American field are broken down in full in the top 20 largest construction companies in the USA.

Europe plays a different game entirely, one built increasingly on concession income rather than contracting revenue alone. That shift now separates the region’s leaders from the rest of the field, and it is covered in length in the report on the 10 largest construction companies in Europe.

Australia and Oceania

Australia closes out the regional picture, and CIMIC’s dominance there tells its own story about how quietly ACS and HOCHTIEF have built one of the most complete footprints in global construction. The full ranking places it among the top 20 largest construction companies in Australia.

Inside the Numbers: Revenue, Backlog, and Market Concentration

Understanding this ranking requires looking beyond headline revenue to the mechanics that determine whether a company’s position is stable or vulnerable to a single bad contract cycle.

1. Revenue Concentration Among the Top Five

The five Chinese state-owned enterprises account for approximately 62% of combined Top-20 revenue, a level of concentration unmatched in most other global industries at this scale. This concentration stems from China’s construction output, which, together with that of the United States and India, accounts for over half of global construction activity, according to forecasts from Oxford Economics and GlobalData. Any material slowdown in Chinese domestic infrastructure spending would therefore ripple through the aggregate figures across the entire ranking, even though individual Western contractors would remain largely insulated.

2. Revenue Versus Market Capitalisation

Revenue rank and market value diverge sharply across this list. State-owned Chinese firms trade at low price-to-earnings multiples relative to revenue because investors discount for limited disclosure and government influence over capital allocation decisions. By contrast, HOCHTIEF’s 2026 entry into Germany’s DAX index reflected investor confidence in its data centre backlog rather than its revenue rank, which sits well outside the global top five. Market capitalisation, in other words, rewards visible, high-margin backlog over sheer contracting volume.

3. Backlog as a Leading Indicator

Backlog figures, when disclosed, offer a better forward-looking signal than trailing revenue. ACS Group’s record €92.9 billion backlog, against €49.9 billion in FY2025 revenue, implies close to two years of secured work, while Turner’s USD 44.3 billion backlog, against USD 29.2 billion in revenue, suggests similarly strong visibility. Companies that do not disclose group-level backlog, a pattern common among the Chinese state-owned firms, are harder to assess on this basis, which is itself a data point worth weighing when comparing counterparty risk across the ranking.

Conclusion: What the World Rankings Reveal About Construction’s Future

Ranked by annual revenue, the world’s largest construction companies today look structurally different from the sector’s leaders a decade ago. Chinese state-owned enterprises still dominate by sheer revenue, built on a domestic infrastructure base that no other country can replicate, but their growth increasingly depends on exporting that model through Belt and Road contracts across Africa, Central Asia, and the Middle East. Meanwhile, a smaller group of European and American firms has found a more profitable path: fewer, larger contracts tied to AI data centres, semiconductor fabrication, and energy transition infrastructure, backed by disclosed multi-year backlogs that make their growth easier to forecast and finance.

For engineers, investors, and project owners evaluating these firms as partners or benchmarks, the lesson is that rank alone should never substitute for due diligence on backlog quality, disclosure practices, and geographic concentration risk. A contractor’s position on this list captures where it stands today, not necessarily where its pipeline will take it over the next three to five years. The firms best positioned for durable growth, based on the evidence in this ranking, are those that combine scale with transparent, diversified order books, rather than those that rely on a single dominant market or client relationship.
