Top 10 Best Infrastructure Companies In UAE 2026

The United Arab Emirates is in the middle of one of the most aggressive infrastructure build-outs in the world, and the companies delivering that work are operating at extraordinary scale. According to Mordor Intelligence's UAE Infrastructure Market report, the sector remains one of the Gulf's most active, driven by airport expansions, rail networks, energy transition projects, and megadevelopments across Abu Dhabi, Dubai, and Sharjah. Our ranking of the top 10 best infrastructure companies in UAE for 2026 draws on RevenueBase company data from September 2026, Forbes Middle East's Top 10 Construction Companies 2026, RIB Software's UAE rankings, and GlobalData's Q3 2026 UAE Construction Market report.

How We Ranked These

We weighed workforce size, the scale and profile of completed and active projects, recent contract awards, and placements on independent industry lists. Sources included RevenueBase's infrastructure development and pipeline/utility construction rankings (September 2026), Forbes Middle East's regional Top 10, RIB Software's UAE Top 10, and GlobalData's Q3 2026 construction market data. Firms with major UAE operations and verifiable delivery records ranked highest. No company paid for inclusion, and no weighted scoring tables were used. Every placement reflects publicly reported figures.

The Top 10 Best Infrastructure Companies In UAE 2026:

1. Trojan Construction Holding (Trojan Construction Group)

Trojan Construction Group, a subsidiary of Alpha Dhabi Holding PJSC, is the largest infrastructure contractor operating out of the UAE by workforce. The company employs more than 36,000 people and has completed over 200 projects, laying 2,500+ kilometers of roads, utilities, and railways across the Emirates.

The project list is the strongest argument for the top spot. Trojan delivered Zayed International Airport, the Etihad Rail network, the Guggenheim Museum Abu Dhabi, and Maple Phase 1, 2 and 3 at Dubai Hills Estate. Etihad Rail alone is a national undertaking, a 1,200-kilometer network designed to link the seven emirates and connect the UAE to Saudi Arabia at the border.

Forbes Middle East recognized Trojan Construction Holding, led by Ahmed Al Shamsi, among its Top 10 Construction Companies 2026 for the Middle East. No other UAE-headquartered firm combines this headcount, this project portfolio, and this level of independent recognition.

2. ALEC Engineering and Contracting (ALEC Holdings)

ALEC has been headquartered in Dubai Marina since its founding in 1999, and under CEO Barry Lewis it has become one of the most awarded contractors in the region. The firm's reputation rests on delivering complex, large-scale projects on schedule, a claim backed by its "Building Project of the Year" win at the MEED Project Awards.

In May 2026, ALEC received a Letter of Award from the Department of Culture and Tourism - Abu Dhabi for the Sphere Abu Dhabi venue project. That single award reshapes Abu Dhabi's entertainment and tourism infrastructure pipeline, and it went to ALEC.

Forbes Middle East placed ALEC Holdings on its Top 10 Construction Companies 2026 list for the Middle East. The combination of a fresh, high-profile award and consistent delivery recognition explains the number two position.

3. Khansaheb Civil Engineering

Few contractors anywhere in the world can claim nearly nine decades of continuous operation. Khansaheb Civil Engineering was founded in 1935 and has been building in the UAE ever since, making it the oldest firm on this list. Tariq Khansaheb serves as Chairman.

The company's work spans construction, infrastructure, and facilities management. It was named "Digital Construction Innovator of the Year" by the Middle East Digital Construction Award, a signal that the firm is modernizing how it delivers projects rather than coasting on longevity.

RIB Software ranked Khansaheb number one on its 2026 list of the Top 10 Construction Companies in the UAE, citing size, reputation, and complex signature projects. That independent number one placement, combined with the firm's institutional history, puts it third here.

4. Orascom Construction PLC

Orascom Construction PLC topped Forbes Middle East's "The Middle East's Top 10 Construction Companies 2026" list. That ranking weighed value of projects completed, backlog and pipeline, revenues and total assets, geographic reach, and transparency. Orascom finished first in the region on those measures.

The company operates across the UAE and the wider Middle East under CEO Osama Bishai, with a track record in large-scale infrastructure and engineering delivery. Its financial depth and project pipeline distinguish it from contractors that operate in a single market.

Orascom ranks fourth in our UAE-focused list because its operations are regional rather than UAE-concentrated, while its Forbes number one regional placement keeps it firmly in the top tier.

5. KENTZ (Kent plc)

KENTZ, part of Kent plc and headquartered in Dubai, specializes in engineering, procurement, and construction for pipeline, utility, and energy infrastructure. With over 10,001 reported employees, it ranks among the largest employers in the UAE's pipeline and utility construction sector.

RevenueBase ranked KENTZ number two among pipeline and utility construction companies based in the UAE as of September 2026, with 3,987 tracked professional contacts. The firm's workload centers on oil, gas, and energy transition projects across the region, a segment where UAE spending remains heavy.

Energy infrastructure is the backbone of the Emirati economy, and KENTZ sits directly on that backbone. That positioning earns it fifth place.

6. Lamprell

Lamprell, headquartered in Sharjah, is the highest-ranked pipeline and utility construction company in the UAE on RevenueBase's September 2026 list, taking the number one spot in that category. The firm reports between 5,001 and 10,000 employees and 6,080 tracked professional contacts, the most networked firm in its category.

Fifty years of experience in oil and gas infrastructure underpins the business, but the more interesting story is offshore wind. Lamprell has positioned itself in the global offshore wind market, delivering complex energy infrastructure that aligns with the energy transition agendas of both the UAE and its international clients.

A number one category ranking plus five decades of delivery explains the sixth position, even though the firm sits below larger general contractors on this list.

7. Al Naboodah Construction Group (ANCG)

Al Naboodah Construction Group is an Emirati-owned family business founded in the early 1960s, employing approximately 10,000 people. Its portfolio spans construction, renovation, civil engineering, and MEP services, with additional expertise in building, ready-mix concrete, and specialized plants and equipment.

The project record is unusually varied. ANCG completed terminal expansions, heliport construction, and runway and airfield enhancements for Dubai International Airport. It built the service tunnels for the Palm Jumeirah "floating city" and the Yas Island vehicular tunnel. Airport and marine infrastructure work at this level demands precision that general building contractors rarely develop.

RIB Software ranked Al Naboodah number 10 on its 2026 Top 10 Construction Companies in UAE list. The depth of its infrastructure specialization earns it seventh place in our ranking.

8. Al Sahraa Group

Founded in 1983 and headquartered in Abu Dhabi, Al Sahraa Group has grown into one of the UAE's largest road transportation and infrastructure firms. RevenueBase records between 5,001 and 10,000 employees as of September 2026, along with 310 tracked contacts.

The company operates a large fleet and has been a long-standing partner on federal and emirate-level road projects. Road transport infrastructure is easy to overlook next to headline megaprojects, but the UAE's road network carries the freight, commuter, and logistics traffic that everything else depends on.

Four decades of road infrastructure leadership and a workforce approaching 10,000 place Al Sahraa eighth.

9. Colas Middle East

Colas Middle East, headquartered in Dubai, is a subsidiary of the global COLAS Group, one of the most recognized names in transportation infrastructure construction and maintenance worldwide. The firm focuses on road construction, maintenance, and transport infrastructure across the UAE and the broader Middle East.

UAE headcount is smaller than most firms on this list, reported at 501 to 1,000 employees with 92 tracked contacts. What the company lacks in local headcount it offsets with access to the COLAS Group's global technical resources and engineering bench.

RevenueBase ranked Colas Middle East among the top 25 infrastructure development companies based in the UAE as of September 2026. The global backing and specialized road expertise justify ninth place.

10. Green Oasis Contracting (Green Oasis General Contracting Co.)

Green Oasis Contracting, headquartered in Dubai, is a general contracting firm ranked number seven among infrastructure development companies based in the UAE by RevenueBase as of September 2026. The company employs between 1,001 and 5,000 people and maintains 315 tracked professional contacts.

Its presence in the UAE contracting market has expanded steadily, and the top-10 RevenueBase placement reflects a growing role in delivering civil and infrastructure works across the Emirates. For a firm of its size, that ranking puts it ahead of several larger competitors in the infrastructure development category.

A sizable workforce and a verified top-10 placement secure the final spot on our list.
