Rising Costs of Broadband Construction

Key Takeaways

• Median buried fiber cost reached $18 per foot in 2025
• Aerial construction cost rose 14% to $8 per foot
• Labor accounts for over 70% of buried construction expenses
• 88% of respondents anticipate cost increases in 2026
• Direct burying fiber costs 40% less than new conduit

Summary

The Fiber Broadband Association’s 2025 annual report shows median fiber construction costs climbing to $18 per foot for buried lines and $8 per foot for aerial routes, marking 3% and 14% increases respectively. Labor remains the dominant expense, representing roughly 70% of buried and 64% of aerial costs. Surveyed builders across 38 states expect further price pressure, with 88% forecasting cost rises in 2026—62% anticipate modest increases under 10% while 26% see hikes above that threshold. These trends raise concerns for projects funded by BEAD grants and other large‑scale deployments.

Pulse Analysis

The latest Fiber Broadband Association report highlights a clear upward trajectory in fiber deployment expenses, driven primarily by labor inflation. While buried construction now averages $18 per foot and aerial work $8 per foot, the underlying cost drivers differ: buried projects are labor‑intensive, with crews spending up to 72% of total outlays on wages, whereas aerial installations, though cheaper per foot, saw a sharper 14% price jump. Understanding these dynamics is crucial for investors and operators who must factor labor market volatility into project budgets.

Regional cost disparities further complicate national averages. The survey, spanning 38 states and a mix of urban, suburban, and rural builders, masks significant variations in wage structures—from prevailing and union rates to market‑based contracts. Smaller ISPs, often relying on subcontractors, may experience higher per‑foot costs than large carriers with economies of scale. Moreover, construction methods matter: directly burying fiber is 40% cheaper than installing new conduit, while trenching remains the most expensive technique, outpacing plowing and directional boring.

Looking ahead, the consensus among 88% of respondents is that 2026 will bring additional cost pressure, with a majority expecting modest increases and a quarter foreseeing double‑digit hikes. This outlook poses a strategic dilemma for projects funded under the BEAD program, which must reconcile grant allocations with potentially 10%‑plus annual cost escalations. Operators may need to adopt more efficient crew configurations, leverage smaller teams for higher productivity, or explore alternative deployment methods to mitigate rising expenses and keep rollout schedules on track.
