The Current State of the Construction Industry in the USA

The construction industry has been a key contributor to the United States economy for centuries, with a market value of over USD $2.2 trillion and continuous growth year after year. This expansion has been seen in residential and commercial construction, as well as major infrastructure construction boosted by federal investment. Despite the influx of government spending to support the growth of construction companies in the USA, private investment has also increased significantly in recent years.

Continuing this positive trajectory will mean resolving ongoing labor shortages, with the industry needing to attract an estimated 34,900 new workers just to fill current openings. Rising material costs, high interest rates, and regulatory challenges can also make it difficult to meet the high demand cost-effectively. Automation and workforce development strategies will help to reduce the skills gap in the years ahead, with higher wages and safer environments making construction work an increasingly popular career choice.

The adoption of construction software, IoT devices, and building information modeling (BIM) are quickly gaining momentum in North America with these tools becoming essential to the growing percentage of US firms shifting focus to green construction practices.

The boom in artificial intelligence (AI) is also impacting the biggest construction companies in the US in many ways, with hyperscale data center projects employing thousands of workers, and predictive analytics, digital twins in construction, and other AI-driven software innovations improving job site quality, decision-making, and efficiency. At the same time, there has been a rapid influx of small firms and independent operators substantially increasing the overall number present in the US.

The Top 10 Construction Companies in the USA in 2026

With almost 3.8 million construction companies in the USA employing more than 10 million people, it’s not so easy to make a top ten selection. Some of the largest industry players in the country are still fairly new to the scene, while others have a century or more of experience completing ambitious building and infrastructure projects. While many factors can be used to rank the top construction companies in the USA, we’ve chosen to prioritize our list according to current annual revenue.

1. Turner Construction

Topping our list of construction companies in the USA is Turner Construction Company. This diverse international building organization has been a major contributor to large and complex projects in the US and around the world since 1902. With 15,000 talented employees on hand helping the company generate USD $29.2 billion in revenue per year with a project backlog of $44.3 billion, Turner Construction has earned their industry reputation by developing steel-reinforced concrete for general building purposes.

Turner was recently honored by Forbes as a top employer for women and new graduates, and also named one of America’s Best Large Employers in 2026.

2. Bechtel Corporation

Bechtel Corporation is another business consistently ranking among the biggest construction companies in the US. This engineering, construction, and project management company was founded in San Francisco, California, in 1898. Its founder, Warren A.

4. Kiewit Corporation

The deep roots of Kiewit Corporation extend beyond many other top construction companies in the USA, following the launch of a small masonry contracting business back in 1884 by brothers Peter and Andrew Kiewit. Complex freeway, energy, and military infrastructure projects filled the company’s portfolio over the ensuing decades, with the company now earning an impressive USD $18.2 billion in annual revenue through their engineering and construction services.

Over 34,500 Kiewit employees enjoy cutting-edge training and meaningful responsibilities that make Kiewit such a sought-after workplace for construction professionals.

With USD $14.1 billion in annual revenue and 13,500 employees, DPR has built their reputation for quality and integrity through a series of sustainable medical, commercial, entertainment, and manufacturing facilities.

Recent projects in the USA include the stunning Block 185 Office Tower in Texas, the Sutter Davis Hospital expansion in California, and many of the largest computer data centers in North America. The self-performing model developed by DPR allows them to complete projects using their existing staff alone, rather than seeking out new contractors or sub-contractors for each opportunity. The company recently put their ambitious sustainability objectives into practice by initiating embodied carbon lifecycle analysis practices.

10. Shanska USA

One of the largest and most financially sound construction companies in the country is Shanska USA, headquartered in New York City.

Construction Companies in the USA FAQs

Like many other nations with a large construction sector, the US industry is contending with high demand for new infrastructure, rising material prices, and stubborn labor shortages. The growth of AI and other emerging technologies has inflated the project pipelines for many major construction firms, while others experience slowdowns from economic headwinds.

Let’s address some of the most frequently asked questions in order to paint a more complete picture of what the US construction industry looks like today.

What is the biggest construction company in the USA?

Based on revenue, Turner Construction Company is the largest, with over USD $29 billion in 2025 edging out the equally impressive $23 billion earned by Bechtel in the same year. Turner has assumed the top spot with less than one-third as many employees - their combined expertise in transportation, healthcare, and commercial construction has also helped them establish a sizable backlog.

Along with Bechtel and Turner, Kiewit, Flour, and AECOM consistently feature among the largest construction companies in the US, each with a long history influenced by increasingly complex projects, proactive construction software integration, and ambitious sustainability and carbon reduction goals.

How many construction companies are there in the USA?

Recent IBISWorld research estimates place the number at approximately 3.8 million, with significant growth seen each year. Many businesses included in this total are specialized contractors who are benefiting from the rise of AI and government investment in infrastructure. The vast majority are one-person firms, meaning they don’t need to hire or train workers. This distinction accounts for other estimates that place the total number of construction companies in the USA closer to one million. US states where residential construction has remained steady, including Texas, Arizona, and Florida, are seeing the most emerging businesses formed.

What challenges are the top USA construction companies currently facing?

The USA isn’t immune to the material price increases, skilled labor shortages, and safety risks being experienced around the world. Additional challenges unique to US firms include sustainability regulations and permitting processes that vary by state, complex construction contracts for mega projects that span many years, and restrictions on imports that force contractors to purchase more expensive materials.

These challenges make it more difficult for small companies to scale and expand into other regions. However, firms are increasingly turning to construction management software to optimize contract management, regulatory, and procurement issues, helping them overcome many of their biggest hurdles.

Which of the top construction companies in USA focus on sustainability?

Sustainability in the construction industry is a major focus area for all the most successful and largest construction companies in the US, including those among our top 10 list. In addition to the rise in sustainable building and renewable energy power plants, Fluor, Turner, and Shanska are throwing their weight behind the growing list of firms setting firm net-zero targets to dramatically reduce their carbon footprint.

Many factors contribute to this positive trend, including government incentives, customer demand, and a shift to green modular construction methods that can accelerate schedules and compensate for labor shortages.

How do I choose the best construction company?

In most cases, having a set of clear requirements with a realistic budget is a good starting point, but these decisions should never be based on the lowest bid. Interactive subcontractor management databases allow clients and general contractors to verify relevant experience and review licenses, references, and other credentials all in one place. Construction software solutions for bid management, takeoff and estimation, and procurement also make it easier to perform apples to apples company comparisons.

Final Thoughts

As the demand for smarter, faster, and more sustainable building solutions grows, construction companies in the USA are under increasing pressure to adapt and lead. Those that embrace digital transformation, prioritize skilled labor, and stay ahead of regulatory and economic shifts will be best positioned for long-term success, successfully navigating the industry’s opportunities and risks.
