Bridge & Structural Drone Inspection in New Hampshire

Mountain to Coast provides professional drone inspection services for bridges, overpasses, retaining walls, and other critical structures throughout New Hampshire and New England. Our FAA Part 107 certified pilots deliver detailed aerial documentation that supports engineering assessments, maintenance planning, and regulatory compliance — without the cost and disruption of traditional access methods.

Why Drone Inspection for Bridges & Structures?

Conventional bridge inspection requires lane closures, under-bridge inspection vehicles (snooper trucks), rope access teams, or scaffolding. These methods are expensive, disruptive to traffic, and put inspectors in hazardous positions. Many structural elements — tops of piers, undersides of deck joints, inside bearing seats — are difficult or impossible to access safely with traditional methods.

Drone-based structural inspection changes the equation. Our aircraft access hard-to-reach areas in minutes, capturing high-resolution imagery of every structural element without lane closures, heavy equipment, or risk to human inspectors.

What We Inspect

  • Highway and municipal bridges — deck condition, expansion joints, drainage systems, railing integrity
  • Bridge substructure — piers, abutments, bearing seats, scour assessment around foundations
  • Overpasses and elevated roadways — underside inspection without traffic disruption
  • Retaining walls — cracking, displacement, drainage condition, vegetation intrusion
  • Dam structures — face condition, spillway inspection, erosion assessment
  • Culverts and drainage structures — inlet/outlet condition, debris accumulation, structural integrity
  • Parking garages and elevated structures — concrete deterioration, rebar exposure, joint condition

What You Get

  • High-resolution close-range imagery — detailed photos of every structural element from angles inaccessible to ground-based inspection
  • Crack mapping and measurement — documented crack patterns with scale references for engineering assessment
  • Condition documentation reports — organized findings with annotated imagery supporting NBIS element-level inspection
  • Comparison datasets — repeat inspections that show condition changes over time
  • 3D structural models — photogrammetric models for detailed analysis and measurement (available on request)

Our Process

1. Pre-Inspection Coordination — We review bridge plans and previous inspection reports, coordinate with your engineering team, and develop a flight plan targeting all required structural elements.

2. Aerial Data Collection — Our pilots execute systematic flight patterns around the structure, capturing comprehensive imagery of deck, superstructure, substructure, and surrounding conditions. No lane closures required for most inspections.

3. Reporting & Deliverables — We organize and annotate all findings into a professional report, with imagery sorted by structural element and location.
