NYC's Construction Market at a Glance
The largest construction companies NYC tracks are concentrated at the top, not evenly distributed. AECOM Tishman / AECOM Hunt nearly doubles the NY-area revenue of the #2 firm, and pulls $2.5 billion ahead of #3. That kind of gap signals consolidation, not parity.
Geographic scope: Crain's defines the NYC market as New York City plus Nassau, Suffolk, and Westchester counties in New York, and Bergen, Essex, Hudson, and Union counties in New Jersey1. Rankings reflect NY-area revenue, not global revenue.
This matters for any apples-to-apples comparison. Turner Construction, for example, ranks #3 inside NYC but holds the #1 spot among national contractors in the U.S.2 A firm's NYC standing and its national footprint can tell two very different stories.
The Top 10 NYC Construction Companies by Revenue (2024)
Ten firms dominate NYC's construction market, with AECOM Tishman / AECOM Hunt nearly doubling the revenue of #2 STO Building Group. The table below compiles the top tier by 2024 NY-area revenue, with notes on national context where relevant.
| Rank | Firm | 2024 NY-Area Revenue | HQ | Specializations | Notable NYC Work |
|---|---|---|---|---|---|
| 1 | AECOM Tishman / AECOM Hunt | $4.2B1 | New York, NY | Public infrastructure, commercial towers | JFK modernization, JP Morgan Chase Building |
| 2 | STO Building Group | $2.4B1 | New York, NY | Commercial interiors, healthcare, residential (via subsidiaries) | Operates Structure Tone, LF Driscoll Healthcare, Pavarini McGovern |
| 3 | Turner Construction | $1.7B (NY-area)1 / $17B global2 | New York, NY | Commercial, healthcare, data centers | ENR's #1 national contractor, three years running3 |
| 4 | Hunter Roberts Construction Group* | ~$1.1B | New York, NY | Commercial, healthcare, hospitality | Major NYC commercial work |
| 5 | J.T. Magen & Company* | Single-source figure | New York, NY | Commercial interiors, mid-market | Founded 1992 |
| 6 | Skanska USA* | $6.9B national4 | New York, NY | Civil infrastructure, commercial | U.S. arm of Sweden's Skanska AB5 |
| 7 | Gilbane Building Company* | $1.4B NYC (2019 figure)6 | Providence, RI / New York office | Commercial, education, healthcare | Long-standing NYC presence |
| 8–10 | Additional Crain's-listed firms* | Verify current Crain's listing | — | — | — |
*Single-source or dated figure. Verify against the current Crain's New York Business listing1 before using in client work. Skanska's $6.9B reflects U.S.-wide revenue, not the NY-area subset. The Gilbane figure is from 2019.
There are two takeaways worth pausing on. First, the revenue gap from #1 to #3 is wider than the gap from #3 to #10— top-end consolidation is real. Second, "biggest in NYC" and "biggest in the U.S." are not the same ranking. Turner shows that clearly.
Profiles of NYC's Top Construction Firms
AECOM Tishman, STO Building Group, and Turner Construction lead NYC by revenue but differ sharply in structure, specialization, and national footprint. Each operates with a different business model behind the headline number.
AECOM Tishman / AECOM Hunt
AECOM Tishman / AECOM Hunt holds the top position with $4.2 billion in New York-area revenue in 2024— up roughly 20% from the year prior1. The combined entity acts as AECOM's NYC-area construction presence and traces its lineage back to Tishman Construction, with a history dating to 18987.
Key stats:
- 2024 NY-area revenue: $4.2 billion (+20% YoY)1
- Specializations: large-scale public infrastructure, commercial towers
- Anchor projects: JFK Airport modernization, JP Morgan Chase Building
The growth rate is the part to underline. A 20% revenue lift at a $4 billion run-rate is not a normal year. It reflects how much of NYC's mega-project pipeline runs through one firm.
STO Building Group
STO Building Group ranked #2 with $2.4 billion in revenue and operates as a portfolio of construction brands rather than a single contractor. Its three NYC-relevant subsidiaries— Structure Tone, LF Driscoll Healthcare, and Pavarini McGovern— handle commercial interiors, healthcare, and residential work respectively1.
Key stats:
- 2024 NY-area revenue: $2.4 billion1
- Structure: Holding group with multiple operating brands
- Specializations: commercial interiors, healthcare construction, residential
The portfolio model is the differentiator. STO can compete in interiors and healthcare without a single brand carrying every relationship. For mid-market firms thinking about acquisitions or sub-brands, it's a useful model to study.
Turner Construction
Turner Construction ranks #3 inside NYC at $1.7 billion in NY-area revenue but #1 nationally with $17 billion in global revenue2. Turner has held the top spot on Engineering News-Record's list of the top 400 commercial contractors for three consecutive years3.
Key stats:
- 2024 NY-area revenue: $1.7 billion1
- Global revenue: $17 billion2
- Employees: more than 10,000 worldwide8
- Specializations: commercial, healthcare, data centers, telecommunications
That national-vs-NYC split is the cleanest illustration of why "biggest" depends on the boundary you draw. Turner is the largest construction contractor in the U.S. and only the third-largest in NYC.
The Operational Edge: How Top NYC Construction Firms Manage Data and Coordination
Construction firms operating at the AECOM and Turner scale solve a problem most mid-market firms underestimate. Industry research published by Panzura found that construction teams lose 5.5 hours per week searching for project information9, and rework costs— driven partly by coordination gaps— consume 14% of project budgets9. At a $50M revenue firm, that 14% is $7M.
The drag on every project: - 5.5 hours per worker per week lost to file search9 - 14% of project budgets lost to rework9 - $5.21 million average cost per ransomware incident in industries handling sensitive project data, with 91% of incidents involving data theft10
Top firms invest heavily to neutralize that drag. The pattern repeats across the leaderboard: centralized file systems that act as a single source of truth, BIM/CAD collaboration tooling that lets distributed teams work on the same model in near-real-time, and ransomware-resilient storage that protects years of project data from a bad Tuesday morning. None of this is glamorous. All of it is load-bearing.
The operational implication scales with revenue. Centralized project data is not a back-office concern at $4 billion in revenue— it's a moat. Firms that move first on AI-augmented review, automated coordination, and resilient infrastructure widen the gap on firms that defer those decisions. And mid-market AEC firms feel the squeeze whether or not they name it that.
What "Bigger" Means for Mid-Market AEC Firms
For founder-led AEC firms in the $20M–$100M range, the gap between you and AECOM isn't headcount. It's the operating systems, data infrastructure, and AI augmentation that let larger firms run more projects per person. You don't need to be a $4 billion firm to operate like one. You need the systems and decision frameworks they spent decades building.
Three areas tend to move the needle for growing firms:
- Project data centralization. A single source of truth for plans, RFIs, submittals, and field reports— not five overlapping folders across three platforms.
- AI-augmented review and coordination. Pattern-spotting on drawings, automated cross-referencing of specs, and assistant-style support for PMs whose calendars are already full.
- Decision frameworks for tech investment. A way to say no to the next vendor pitch without losing track of what would actually move the firm forward.
The framing matters. AI in this context is intellectual augmentation, not replacement— it frees PMs and engineers from coordination drag so they can spend their hours on the work that needs human judgment. That's where the operational gap closes. Not by adding bodies. By removing friction.
If mapping the right tools to your specific workflows feels like a full-time job on top of running the firm, an AI implementation partner for AEC firms can compress that work into weeks rather than quarters. We help founder-led firms define an AI strategy roadmap that prioritizes the highest-leverage workflows first.
Frequently Asked Questions
Below are the most common questions about NYC's largest construction companies, answered with current 2024–2025 data.
What is the biggest construction company in NYC?
AECOM Tishman / AECOM Hunt is the biggest construction company in NYC by revenue, with $4.2 billion in New York-area revenue in 2024— up roughly 20% year over year1. The combined entity is the NYC-area presence of AECOM and ranks well ahead of the next-largest firm.
How does Turner Construction rank in NYC versus nationally?
Turner Construction is the #1 contractor nationally per Engineering News-Record with $17 billion in global revenue and has held that position three years running23. Inside NYC, Turner ranks #3 by tristate revenue at $1.7 billion1.
Does "NYC" in these rankings mean only the five boroughs?
No. Crain's NYC-area rankings cover New York City plus Nassau, Suffolk, and Westchester counties in New York, and Bergen, Essex, Hudson, and Union counties in New Jersey1. Comparing rankings from different publishers can produce different orderings depending on the geographic boundary used.
How many employees do top NYC construction firms have?
Turner Construction employs more than 10,000 workers globally8. Firm size varies sharply by specialization— commercial-interiors firms typically run leaner than infrastructure-focused firms with self-perform crews.
What's the biggest operational challenge facing large construction firms?
Project data fragmentation. Industry research shows construction teams lose 5.5 hours per week searching for project information, and rework costs driven partly by coordination gaps consume about 14% of project budgets9. At scale, that drag is the difference between profitable projects and break-even ones.
Bottom Line
AECOM Tishman, STO Building Group, and Turner Construction lead NYC's construction market by revenue, but the firms behind them are closing ground through operational and technology investments— not just bigger crews. Revenue rankings show who is biggest. The systems behind them show who is built to stay there.
If you're sizing your firm against this list, the right next question isn't "how do we hire faster." It's "what systems and AI capabilities should we be investing in now, so the next $10M of growth doesn't break our operations." That's the work we do with founder-led AEC firms— see our consulting services for how we engage, and our ongoing guidance for founders navigating this stage.
