United States Engineering Services Market Analysis by Mordor Intelligence

The U.S. engineering services market size reached USD 175.21 billion in 2025 and is projected to advance to USD 271.01 billion by 2030, reflecting a firm 9.12% CAGR. Accelerated federal infrastructure outlays under the Infrastructure Investment and Jobs Act, the CHIPS and Science Act’s semiconductor incentives, and persistent defense-modernization budgets are sustaining a multi-year pipeline of complex projects that require deeper engineering expertise. Demand patterns are also being reshaped by manufacturing reshoring, grid-modernization imperatives, and the rapid commercialization of digital-twin workflows that cut rework and expand lifetime asset-management revenues. Competitive behavior is shifting toward acquisitions aimed at specialty capabilities—especially in clean-energy systems, advanced manufacturing, and AI-enabled design—while clients’ cost pressures are encouraging integrated EPCM models. Regional demand is clustering around California, Texas, the Great Lakes corridor, and fast-growing Southeast metros where fiscal incentives, lower land costs, and pro-business regulation encourage sustained capital deployment.

Segment Analysis

By Application: Civil Engineering Anchors the Infrastructure Renaissance

Civil engineering captured 34% of 2024 revenue, underscoring its pivotal role in the bridge rehabilitation, highway expansion, and resilient water systems funded by the IIJA. Projects such as California’s high-speed rail and the Gateway Tunnel boosted demand for seismic retrofits, geotechnical modeling, and tunnel-boring oversight, ensuring a steady backlog that underpins the U.S. engineering services market. The segment benefits from increasing design-life requirements and climate-resilience standards that extend scoping phases and raise billable complexity.  

Mechanical engineering is the fastest-advancing discipline due to semiconductor fabs, battery plants, and hyperscale data centers that require cleanroom HVAC, high-density thermal-management, and robotics integration. Electrical engineering demand is equally brisk, spurred by grid-modernization and EV charging corridors, pulling in relay-protection, medium-voltage design, and smart-meter analytics services. Environmental engineering has expanded beyond remediation into climate-risk modeling, carbon-capture systems, and ESG compliance, adding premium services that tack onto standard civil scopes. Chemical engineering remains a niche yet lucrative field for semiconductor etching processes, advanced pharmaceutical lines, and specialty materials, lifting average hourly rates across the U.S. engineering services market.

By Service Type: Consulting and Design Dominate as Digital Maturity Accelerates

Consulting and design captured 40% of market revenue in 2024, driven by owners’ desire for front-end expertise in BIM coordination, supply-chain localization, and resiliency planning. Digital-first delivery, including cloud-hosted common data environments and AI-assisted code checks, is reducing rework and shifting value upstream, reinforcing the segment’s lead position in the U.S. engineering services market.  

Process-and-plant engineering recorded outsized growth through mega-fab and gigafactory projects, where ultra-pure water, inert-gas systems, and robotic line-balancing demand deep specialty knowledge. Automation and digital-engineering services represent the highest CAGR outlook in the segment, linking sensor integration, edge analytics, and digital-twins that monetize post-commissioning optimization. Asset-management services are evolving into performance-based, data-subscription models that generate recurring cash flows, stabilizing top-line trajectories across the U.S. engineering services industry.

By End-User Industry: Infrastructure Funding Keeps Construction at the Forefront

Construction and infrastructure owners drove 38% of 2024 demand as federal and state programs funded highways, bridges, and airports needing multi-disciplinary teams. Long-dated appropriations shield this revenue stream from broader economic cycles, cementing its primacy within the U.S. engineering services market.  

Semiconductor and battery manufacturing investments are the fastest-expanding verticals as fabs require class-1 cleanrooms, fault-tolerant power, and continuous improvement engineering long after start-up. Utilities follow closely, propelled by transmission upgrades and renewable integration that necessitate power-systems and environmental-compliance support. The shift toward hydrogen, carbon capture, and offshore wind is pivoting oil-and-gas spend toward lower-carbon projects, sustaining process-engineering needs inside the U.S. engineering services market.

By Engagement Model: In-House Control Persists Despite Outsourcing Surge

In-house teams sustained 60% of total value in 2024, highlighting owners’ desire to guard intellectual property and maintain project oversight in defense, tech, and automotive sectors. Embedded engineers ensure alignment between design decisions and corporate strategy, preserving core know-how inside firms’ walls.  

Outsourced and EPCM engagements absorb surge workloads, specialized skills, and multi-jurisdiction complexity. Mega-projects increasingly bundle design, procurement, and construction management into single contracts to manage interface risk and schedule compression, deepening external wallet share. Digital collaboration platforms now link owner, engineer, and constructor, shrinking change-order cycles and elevating transparency across the U.S. engineering services market.

Geography Analysis

California captured 15% of national revenue in 2024, buoyed by seismic retrofits, high-speed rail, and strong cleantech investment that require advanced civil and mechanical skills. Grid-hardening against wildfire risk and offshore wind-port upgrades further amplify opportunities. Texas followed at 12%, where petrochemical, renewable energy, and semiconductor projects combine with an accelerated highway program to keep engineering utilization high.  

New York and Florida each accounted for roughly 8%, though their demand mixes differ: New York focuses on rail tunnels, transit upgrades, and offshore wind transmission; Florida channels spend into flood-control, airport expansion, and aerospace payload facilities. The Southeast corridor—from North Carolina through Georgia—benefits from auto-assembly plants, battery factories, and data centers, translating into double-digit CAGR potential for the U.S. engineering services market.  

Mountain-West states such as Arizona, Colorado, and Utah are absorbing population inflows and hosting major semiconductor fabs, fueling specialty MEP and environmental scopes. The Midwest is attracting EV-related investments that rekindle its manufacturing base, while the Pacific Northwest leverages aerospace and hydropower expansion to sustain high-value engineering demand. These shifts point to a geographically broadening U.S. engineering services market over the forecast horizon.

Competitive Landscape

The top 10 firms captured about 25% of revenue in 2024, leaving ample whitespace for regional specialists and niche technology vendors. Scale players such as AECOM, Jacobs, and Bechtel leverage global talent pools and integrated EPCM capabilities to win multi-billion-dollar programs, whereas mid-market firms defend share through local relationships and sector-specific depth. Digital investment is the battlefield: firms with cloud-based BIM, AI-assisted design, and twin-enabled asset monitoring win scope that once flowed strictly to construction managers.  

M&A activity accelerated to 427 deals in 2024, mainly to acquire specialty environmental, power-systems, and data-analytics shops that accelerate digital transformation. Software vendors including Autodesk and Bentley are embedding deeper into owner workflows, potentially disintermediating traditional consultants on lower-complexity tasks, but also partnering with engineering houses for high-end model creation. Diversification into quantum-computing infrastructure, lunar-surface construction, and advanced biopharma plants hints at new frontiers for the U.S. engineering services market.  

Firms seek resilience through balanced portfolios: infrastructure for recession-proof cash flows, industrial megaprojects for margin upside, and OandM digital services for recurring revenue. Labor scarcity is prompting heavy recruitment from adjacent industries and universities, raising competition for talent across the U.S. engineering services market.
