The ENR 2026 Top 500 Design Firms: AI Lifts the Whole Industry
A Rising Tide
The numbers are in, and the message is clear: AI-driven infrastructure is rewriting the growth story for design firms. Overall, Top 500 firms recorded a 7.4% increase in total revenue last year, reaching $158.7 billion. Breaking that down further, domestic design revenue rose 8.1% to $136.3 billion, while international revenue climbed 3.2% to $22.4 billion.
Data Centres Are the Engine
No sector better illustrates this shift than data centres. Jacobs returns to the No.1 position on the 2026 list, with its Data Centre business jumping 62.2%, surging its project pipeline by 500%. In a recent press release, Jacobs’ president Partick Hill describes the firm’s edge as rooted in long-term client relationships and “higher community expectations”, helping clients anticipate growth, climate pressures, and regulatory change ahead of time.
With economists forecasting that an expected $1.75 trillion in AI-related infrastructure spending will drive U.S. economic growth well into 2027, the phrase “a rising tide lifts all boats” has rarely felt more apt for the design sector.
Navigating Federal Uncertainty
Not all tailwinds are equal. Firms with heavy public-sector exposure are feeling the headwinds. Garver (ranked No. 85) has flagged significant swings in government funding as federal infrastructure changes. For firms like Woolpert(No. 36), the federal regulatory shift won’t just be in how quickly permits are issued; it will be in how projects are fundamentally conceived and delivered, with integrated architecture, engineering, and geospatial capabilities becoming the differentiator.
Sustainability as Performance, Not Add-On
For SSOE Group, resilience and sustainability now translate directly into facility uptime, energy cost management, and future-proofed capital investments; a sign that sustainability is moving from a compliance checkbox to a core design philosophy.
The Bottom Line
The ENR Top 500 confirms what we’re seeing on the ground: firms that have invested in Data Centre capability, digital delivery, and integrated services are pulling ahead. For MEP practices, the challenge is positioning early, in both talent and technology, to capture the next wave.
The Talent Squeeze Continues
Even as revenues climb, the talent story remains one of the most pressing challenges in MEP, with the 2026 ENR Top 500 report reinforcing that this pressure is not easing. The gap between project demand and available engineering resources continues to pressure firms, particularly in electrical and environmental disciplines.
Key themes emerging across the sector:
- Firms are competing harder than ever for experienced MEP engineers, particularly those with data centre or advanced infrastructure experience.
- Licensing is always going to be a key aspect of any hiring decision; however, with the demand for experienced individuals to support projects, the decision-making process is being weighted more heavily towards experience over license.
- Geographic flexibility is growing: remote and hybrid roles are being used to access talent in undersupplied markets.
For firms scaling to meet data centre demand, the recruitment strategy is now as critical as technical capability. The companies winning on projects are winning on people first.
Three Firms Merge to Form Lynk Engineers
In one of the most interesting structural moves in the MEP sector this year, three long-established Salt Lake City-based firms, Spectrum Engineers , Colvin Engineering Associates , and Envision Engineering, merged on 6 April 2026 to form Lynk Engineers, a combined MEPT practice with approximately 245 employees.
Each of the three firms brought over 30 years of history and complementary strengths across mechanical, electrical, plumbing, and technology systems. Together they have already delivered landmark projects including the new Salt Lake City International Airport, the University of Utah campus infrastructure upgrade, and the Utah State Prison relocation, the kind of programme-scale work that requires the depth and integration only a larger unified entity can provide.
The Lynk story is worth watching. Peer-to-peer mergers of this kind, where no single firm acquires the others, but all parties combine as equals, are a different model to the PE-backed roll-up or large-firm acquisition that dominates M&A headlines. When it works, it preserves culture and client relationships while unlocking the scale to compete for bigger work.
Colliers Engineering Partners with FSB Architects + Engineers
Announced yesterday (12 May), Colliers Engineering & Design has entered into a definitive agreement to partner with Frankfurt-Short-Bruza Associates (FSB), an Oklahoma City-based multidisciplinary engineering and design firm founded in 1945 with over 140 professionals across five offices.
The deal is expected to close in Q2 2026. It follows Colliers’ February announcement of a US$700 million acquisition of Ayesa Engineering, a Spanish multidisciplinary firm, which on completion will see Colliers Engineering operating across 23 countries with nearly 14,000 professionals. Colliers is building a genuinely global engineering platform at pace with building systems and mission-critical expertise playing an increasingly important role.
SGS and the Future of Data Centre Commissioning
One of the most interesting conversations we had at Data Centre World this year was with David Tyrrell, Business Manager for Commissioning, Qualification & Validation at SGS.
SGS’s Data Centre Commissioning offer is a division that’s grown rapidly as hyperscale and co-location operators demand more rigorous, lifecycle-integrated approaches to commissioning. SGS works across the full data centre lifecycle, from design and construction through to commissioning and long-term operations, embedding commissioning as a core component aligned with construction schedules and handover requirements.
In a recent news article, David put it plainly: “Integrated digital commissioning is the fastest path from construction to reliable operations. When commissioning is treated as a strategic function and supported by live system visibility and structured handover data, uncertainty at the most critical transition point is dramatically reduced.”
For owners and developers navigating compressed schedules and escalating infrastructure complexity, commissioning can no longer be viewed as a final phase, it must serve as the digital backbone that aligns construction, quality assurance, and operational readiness into one coordinated delivery strategy.
SGS operates across 115 countries with over 100,000 professionals, and their data centre commissioning practice is actively scaling to meet demand across hyperscale, Tier III, and Tier IV facilities globally. If you haven’t already crossed paths with David’s team, they’re well worth engaging.
