Succession planning rarely makes it onto the agenda until something changes. A partner signals they want to step back. A client relationship becomes uncomfortably concentrated in one person. An unexpected departure forces the question before anyone’s ready for it. By then, it feels like a crisis, not a strategy.
The firms that handle leadership transitions well got there by building succession into daily operations, not by scrambling when a transition arrives. That discipline is what makes them commercially resilient regardless of who owns or leads them.
Where AEC firms stand today
Succession is a growing conversation across the sector, driven by ageing ownership groups, pressure to bring through the next generation, and profitability challenges in a contracting market. Unanet’s 2025 AEC Inspire Report puts the number of firms with a formal succession plan at just two-thirds. But having a plan on paper and having a business that can actually execute it are two different things.
Average tenure in AEC has dropped from 7 years a decade ago to 4.9 years today, and institutional knowledge is leaving firms faster than most have systems to retain it. Meanwhile, 53% of firms rate themselves “fair” or “poor” at defining formal career paths. That means the next generation is often reaching senior level without the commercial depth the firm needs from them.
Most principals already know their next generation needs more commercial exposure. The real barrier is structural: project delivery consistently takes priority, and the activities that build future leaders get crowded out by the work that keeps the business running.
A structural problem, not a talent problem
Firms that navigate leadership change well tend to share a few traits. Client relationships are spread across the team rather than sitting with one or two people. Business development is a shared practice, not something left to the partners. And delivery is structured so senior staff actually have capacity for mentoring, client relationships, and strategic thinking, not just billable hours.
That structural point matters most in practice. A senior architect buried in delivery has little time left for the things that actually make a future principal: client relationships, business development, mentoring. The structure of the business determines what people have time to become.
Flexible workforce models, adding delivery capacity without growing fixed overhead, give firms a practical lever here. They free up senior staff for leadership development and client relationships, and they protect the margin a transition depends on. A firm under sustained margin pressure has fewer options at every stage, succession included.
Institutional knowledge is the other piece. Much of what makes a firm effective lives in its senior people: how specific clients think, why past decisions were made, what the firm has learned over years of delivery. If that knowledge isn’t captured, incoming leaders inherit the firm without inheriting what makes it work. Firms that invest in documenting and sharing that knowledge internally tend to see the benefit reach well past succession, including more consistent delivery, less dependency on any one person, and a more resilient organization overall.
Building a business that performs through change
Succession planning’s job is to build a firm where transitions get absorbed rather than survived, one that was never dependent on any single person to function. Replacing the people who leave is just the visible part.
A well-structured business also serves both sides of the handover. Principals stepping back want to leave a legacy behind. Those stepping up want to inherit a firm with real commercial foundations under it. When those interests line up around building the business well, succession becomes a win win.
How Away Digital supports this
Away Digital works with architecture and engineering firms to build the dedicated delivery capacity that succession planning depends on. By embedding a remote team into a firm’s tools, standards, and workflows, senior leaders get back the time to invest in leadership development, client relationships, and the commercial foundations a transition needs. The team scales with the pipeline, protects margin, and builds institutional knowledge that strengthens the business over time, through every phase of growth, not just at the point of transition.
For firms thinking about how to structure delivery to support long-term leadership development: What a dedicated remote team really means, and what it doesn’t.
