For many complex projects, mechanical, electrical, and plumbing coordination has become the critical factor behind permit delays. Currently, services associated with MEP engineering and design determine whether a project remains within the forecasted budget.
Revenue for the broader engineering and design services market rose to $459 billion in 2024. This marked a 5.3% growth over the past year. Interestingly, more than half of the member firms declined projects because they lacked sufficient staff.
Why Staffing Shortages Keep Slowing Projects
Just a year back, engineering and design services in the USA directly employed around 1.7 million American workers, supporting 5.7 million jobs nationwide. It is also noticeable that engineering degree completions have remained flat since 2020, even as demand continues to rise. This imbalance forces firms to expand existing staff across more projects than before.
MEP engineering and design services heavily rely on external production support to fill this gap. Local PEs in the USA feel that pressure directly, as stamped drawings still need licensed sign-off irrespective of staffing levels. Firms that are adopting AI for drawing review are actually closing part of that gap. The payoff still takes time to materialize completely, though. Wages climbed to an average of $114,725 in 2024, more than 50% higher than the national average. So, clearly, recruiting alone would not solve a shortage this deep.
Electrical Systems Now Steer the Budget Conversation
Electrical systems accounted for the largest revenue share of MEP service offerings in 2025. This leading position is hoped to remain throughout this decade. Hospitals, data centers, and manufacturing facilities all need heavier electrical loads than they did just a decade ago.
Electrical engineering design services now render more design complexity per square foot than plumbing or mechanical scopes generally do. Rooftop solar interconnections and EV charging infrastructure add even more layers to panel design work. As a result, many firms that still treat electrical coordination as an afterthought often find that it becomes their biggest headache. On-site conflicts and costly rework generally follow closely behind.
Electrical demand climbs further as jurisdictions adopt outcome-based codes necessitating predictive performance assurance throughout all systems. This trend pushes design teams to model electrical loads as early as possible within the process, not after the SD phase’s completion.
Where the Market Pressure Is Concentrated
According to industry research, the MEP services market in the USA is projected to reach $34.6 billion by the end of 2026. A couple of forces explain where that growth actually concentrates:
- Retrofit and renovation captured roughly 47% of the mechanical services market share in 2025
- HVAC equipment costs have increased by almost 40% since 2020, further squeezing project budgets
- Around 77% of fresh projects now need BACnet-compatible building automation systems
- Healthcare facilities specify commissioning on 80% of projects to corroborate readiness
MEP engineering and design services structured around these pressures require capacity that scales with demand, not a fixed headcount. Moreover, copper prices exceeding $5 per pound put more strain on tight budgets. That is why it is vital that firms lock in design choices early to absorb such volatility better than those redesigning under extreme deadline pressure.
What This Means for Local Firms
Local PEs in the USA are watching consolidation rapidly reshape their competitive landscape. WSP’s $1.78 billion acquisition of Power Engineers demonstrates how national players are rapidly absorbing specialized capacity. Independent and local firms cannot always match that scale through hiring alone.
MEP engineering and design services delivered with the help of flexible production partnerships let smaller businesses compete for larger-scale, more complex projects. Electrical engineering design services benefit most from this model because panel and load calculations continue to become more specialized. Regional firms merging, coupling licensed expertise with scalable design support, can still win against larger national competitors.
So, firms that prioritize building this flexibility now can confidently handle the next wave of data center and healthcare projects. Those that still rely solely on internal headcount may keep turning work away.
MEP engineering and design services built for scale, beyond just headcount, will define which firms grow through this cycle and which ones stall out.
