Sustainable success: Navigating growth vs profitability in AEC

Growth is the headline every architecture, engineering, and construction (AEC) firm wants to print.

Opening new offices. Landing bigger projects. Expanding the team. The industry rewards scale and visibility. But under the surface, rapid expansion often brings a different story: shrinking margins, ballooning overhead, and mounting operational headaches.

Many AEC leaders find themselves running a busier business that feels less rewarding, financially and operationally. This is the “growth trap.” Firms chase size, but profitability falls through the cracks. It’s a cycle that takes discipline, and the right tools, to break.

In this blog, we'll explore the tension between growth and profitability, the warning signs of unsustainable expansion, and how AEC firms can use data to chart a healthier path forward.

The Illusion of Growth

Not all growth is created equal. There’s good growth—built on a clear strategy, sound project selection, and a steady hand on costs. Then there’s growth that looks impressive on paper but erodes the financial foundation of the firm.

Good growth means winning the right projects, not just any projects. It means hiring with intention, ensuring teams are neither stretched too thin nor sitting idle. Margins remain stable, overhead stays proportionate, and there’s headroom to invest in new capabilities; be it technology, training, or process improvement. The business grows in a way that strengthens, rather than strains, its core.

Bad growth, on the other hand, is reactive. The firm chases every RFP in sight, adds headcount in bursts to meet immediate demand, and stretches into unfamiliar sectors or geographies. Revenue climbs, but inefficiencies pile up - projects are underquoted, staff are misallocated, and overhead balloons. The bottom line suffers, and the pace becomes unsustainable.

What separates these two paths?

In short: how well you understand your business. Industry data shows a stark divide: AEC firms that prioritize data-driven practices, from project forecasting to resource allocation, can achieve faster profit growth than firms that rely on gut feel. The ability to measure, analyze, and act on the right metrics isn’t just a nice-to-have. it’s the difference between scaling profitably and running on fumes.

Warning Signs & Margin Fade

The signs of unsustainable growth rarely announce themselves with fanfare. They creep in gradually, until suddenly it’s clear that the firm is working harder for less.

Individually, these indicators call for attention. Collectively, they signal a business running on borrowed time, where growth is masking deeper issues. Leaders who know what to look for can spot these red flags before they become a crisis.

‍

Financial Indicators:

• Net Labor Multiplier (NLM) below 3.0: This metric tracks how effectively you’re turning labor costs into revenue. A drop signals that the business is either discounting work, absorbing too many write-offs, or simply not managing project delivery efficiently.

• Overhead Rate above 170%: Overhead - everything from back-office functions to non-billable staff - should scale proportionally with revenue. If it outpaces growth, every pound earned is worth less to the bottom line.

• High Work-in-Progress (WIP) ratio: Projects that linger in WIP tie up cash, delay billing, and muddy financial visibility. Chronic WIP often signals scope creep, delays, or gaps in project management discipline.

• Consistent underquoting: Winning projects shouldn’t always come down to being the lowest bidder. If your win rate is high but margins are flat, it’s likely that estimates are too optimistic, or the true costs of delivery aren’t fully understood.

‍Operational Indicators:

• Utilization Rate below 75-85%: Utilization reflects how much of your team’s effort is billable. Persistent underutilization means you’re either overstaffed or struggling to keep teams busy. Overutilization (beyond 90%) isn’t better, it leads to burnout and mistakes.

• Project over-delivery and scope creep: When teams routinely exceed scope without compensation, project profitability erodes and morale drops. It’s a sign that project controls and client communication need tightening.

• Severe data and team silos: When project managers, finance, and delivery teams each rely on their own systems and spreadsheets, information gets lost. Time goes into reconciling numbers rather than delivering value. These silos lead to duplication, delays, and costly errors.

The Data & Tech Solution

So why do so many AEC firms fall into the growth trap? It’s rarely down to a lack of effort or ambition. More often, the problem is rooted in the operational backbone: outdated systems, fragmented processes, and a reliance on spreadsheets that can’t keep up with complexity.

As firms grow, so does the volume, and the fragmentation, of their data. Project financials live in one place, resource planning in another, and pipeline forecasting in yet another. Teams waste hours chasing down the true status of projects, reconciling conflicting numbers, and piecing together a picture of performance that’s already out of date.

This lack of real-time visibility is the heart of the issue. Decisions get made based on last month’s reports or, worse, on gut instinct. By the time the true health of a project or portfolio is clear, opportunities to intervene have passed.

Centralizing operational and financial data is not a luxury. It’s essential for firms that want to maintain control as they grow. A single source of truth, where projects, resources, and financials are connected, enables timely, informed decisions. Leaders can see margin pressures emerging, spot underutilized staff, and forecast resource needs before the crunch hits. Problems get flagged early, not after the fact.

Conclusion: Leading for the Long Haul

Growth will always be a central ambition for AEC firms. But the firms that thrive are those that balance that ambition with a relentless focus on sustainable profitability. They recognize that scale alone doesn’t guarantee success, and that visibility, discipline, and data-driven decision-making set the foundation for lasting value.

Senior leaders don’t need to choose between growth and profitability. The real work is ensuring they reinforce each other. That starts with honest measurement, clear visibility, and a willingness to invest in the systems that support disciplined execution.

Seeing your business clearly, in one place, is the first step to breaking out of the growth trap. With the right data and the right tools, AEC firms can build not just bigger businesses, but healthier and more resilient ones, ready for whatever comes next.
