A new workforce intelligence report from Bridgit is shedding light on a critical but often overlooked issue in the construction sector: high attrition rates that are quietly erasing workforce gains.
Drawing on data from more than 233 contractors and over 114,000 professionals, the 2026 Construction Workforce Benchmark Report challenges the traditional narrative of a straightforward labor shortage. Instead, it reveals a more complex reality where hiring alone is not enough to sustain workforce growth.
One of the report’s most notable findings is what Bridgit describes as the “treadmill effect.” While a significant 71.7% of contractors increased headcount in 2025, nearly half—46%—reported zero net workforce growth due to turnover.
The report underscores this imbalance with a striking statistic: the industry’s median attrition rate stands at 18.7%, meaning companies must hire far more workers than they actually need to grow.
“Most workforce decisions in construction still happen on instinct and spreadsheets,” said Mallorie Brodie. “What this data shows—drawn directly from the workforce plans of the world’s largest contractors—is that the gap between instinct and data is measured in years of planning horizon and points of attrition. The companies pulling ahead are the ones thinking ahead.”
A Deeper Talent Gap Emerging
Beyond overall headcount, the report highlights a more pressing issue: the shortage of experienced professionals in critical leadership roles.
Senior-level employees—such as superintendents and project managers—demonstrate significantly higher retention rates compared to their junior counterparts. Senior project managers, for example, have an attrition rate of just 3.6%, while non-senior roles experience turnover rates exceeding 18%.
This imbalance suggests that the industry’s real challenge lies not in entry-level hiring, but in developing, retaining, and scaling experienced talent—a factor that directly impacts project delivery, safety, and efficiency.
Shifting Project Demand Adds Pressure
The workforce challenge is further complicated by a rapidly evolving project landscape. The report notes major shifts across construction sectors:
- Industrial and manufacturing project starts surged 68.1% year-over-year
- Transportation and infrastructure projects rose 45.2%
- Data center construction continued strong growth
- Solar project starts declined sharply by 44.4%
These shifts are reshaping workforce needs, requiring contractors to adapt staffing strategies based on project complexity, duration, and team size. For example, solar projects typically require significantly larger teams and longer timelines compared to office or renovation work.
Planning Tools Gain Importance
To address these workforce challenges, the report introduces the concept of a “rookie ratio,” a planning metric that balances experienced workers with newer hires before projects begin.
Across the dataset, the average rookie ratio stands at 36.4%, with larger teams relying more heavily on less-experienced workers. When used strategically, this approach can help firms:
- Maintain productivity across varying project types
- Support mentorship and skill development
- Reduce risk during project execution
Industry Outlook: Beyond Hiring
The findings point to a clear conclusion: the construction industry’s labor shortage cannot be solved through hiring alone. Instead, companies must adopt a more strategic approach that combines:
- Long-term workforce planning
- Data-driven decision-making
- Strong retention and development programs
As construction demand evolves—particularly in infrastructure, manufacturing, and technology-driven sectors—the ability to retain skilled talent and plan effectively will become a defining factor for success.
Ultimately, Bridgit’s report signals a shift in how the industry must think about its workforce—not just as a numbers game, but as a long-term strategic asset.
