Bridge Inspection - Hero

About Us

To protect the traveling public by finding structural problems early, documenting them accurately and helping owners fix them before small defects become costly closures.

Who We Are

About Our Company

H2O Drones provides bridge inspection, load rating support and maintenance construction for transportation agencies and infrastructure owners. Our inspection teams are led by engineers and technicians who understand NBIS requirements, element-level condition assessment, fracture critical member review and scour evaluation. Our maintenance crews perform deck repairs, joint and bearing replacement, steel and concrete repairs, painting and coating work, and emergency response after impact or flood events. We combine field findings with structured reporting, so owners receive clear recommendations that tie directly to preservation budgets and repair priorities.

Bridges rarely fail without warning, and H2O Drones exists to find that warning early. For and nearby agencies, we maintain our own access equipment, safety systems and trained rope access technicians, which lets us inspect difficult structures efficiently and safely. We take care to separate what is urgent from what is routine, and we communicate critical findings immediately rather than waiting for a final report. That approach helps owners protect the public, manage risk and plan interventions that keep structures in service for decades.

Bridge Inspection - Hero

Services

Inspections follow the National Bridge Inspection Standards and agency element-level protocols, led by qualified team leaders who document defects with measurements, photographs and clear recommendations.

Our Advantages

Why Clients Choose Us

Reach Without Large Closures

Rope access, drones and under-bridge units let us inspect long spans, tall piers and over-water structures while keeping lanes open wherever possible.

Critical Finding Notification

If we see a condition that threatens public safety, you hear from us immediately by phone, with photographs and measurements, well before the written report is complete.

Safety Culture For Hard Access

Fall protection, confined space entry, marine safety and traffic control procedures are rehearsed, written and enforced on every structure.

Inspection To Repair Continuity

Because the same company can inspect and repair, defects move from report to work order with fewer handoffs, and we learn from the repairs to improve future inspections.

Qualified NBIS Team Leaders

Inspections are directed by team leaders who meet federal qualification requirements, so findings stand up to review by owners, auditors and structural engineers.

Clean, Usable Data

Element condition states, defect photographs and recommended actions are delivered in formats compatible with agency bridge management systems.

Safety Culture For Hard Access

Rope, confined space and over-water work runs under written rescue planning, because access risk is the real hazard in this trade.

Inspection To Repair Continuity

The firm that identified the defect can also carry out the repair, which removes the handover where findings usually get lost.

Critical Finding Notification

Anything affecting public safety is reported to the owner immediately in writing, rather than appearing weeks later in a report.

Our Services

What We Do

Underwater Inspection & Scour Assessment
Step 01

Underwater Inspection & Scour Assessment

Dive teams and sonar surveys assess piers, footings, pilings and channel conditions below the waterline. We measure scour depth, locate undermining, evaluate marine growth and corrosion on foundations and report findings that support scour critical ratings and plan of action development.

Request a Quote
Expansion Joint & Bearing Replacement
Step 02

Expansion Joint & Bearing Replacement

Replacement of failed strip seals, finger joints and elastomeric, pot or rocker bearings, including temporary jacking and shoring designed by the engineer. Leaking joints and frozen bearings accelerate deterioration of beams, seats and piers, so timely replacement is among the most valuable preservation actions.

Request a Quote
Deck Repair, Overlay & Waterproofing
Step 03

Deck Repair, Overlay & Waterproofing

Removal of deteriorated concrete, rebar cleaning and replacement, patching, latex-modified or polymer overlays and membrane installation to protect decks from chloride intrusion. Chain drag, half-cell and ground-penetrating radar surveys help define the repair limits, so crews remove what is unsound and no more.

Fracture Critical & Hands-On Steel Inspection
Step 04

Fracture Critical & Hands-On Steel Inspection

Close-up examination of fracture critical members and welded details where tension-zone failures could lead to collapse. Inspectors use visual, dye penetrant and magnetic particle methods, as well as ultrasonic testing where required, and document fatigue-prone details such as cover plate ends and welded attachments.

Request a Quote
Routine & In-Depth Bridge Inspection
Step 05

Routine & In-Depth Bridge Inspection

Biennial and special inspections conducted according to the National Bridge Inspection Standards and agency manuals, covering decks, superstructure, substructure, bearings, joints, barriers and channels. Teams record element-level condition states, measure section loss and cracking, photograph defects and deliver reports that feed directly into bridge management systems.

Request a Quote
Load Rating Support & Posting Analysis
Step 06

Load Rating Support & Posting Analysis

Field verification of member dimensions, section loss and material properties supports load rating calculations by licensed engineers. We provide the measurements, condition data and structural details needed for accurate rating factors and for posting or restriction recommendations when capacity is limited.

Request a Quote
Drone, Rope Access & Emergency Response
Step 07

Drone, Rope Access & Emergency Response

Drone imagery and rope access teams document hard-to-reach areas with limited lane closures, while rapid response crews assess strikes, fires and flood damage and install temporary supports. Findings are delivered the same day so owners can decide about closures and load restrictions without delay.

Request a Quote
Steel Repair, Painting & Coating Systems
Step 08

Steel Repair, Painting & Coating Systems

Spot and full repainting of steel superstructures, including abrasive blast cleaning, containment, primer and topcoat application, plus cut-out and replacement of corroded plates and connection repairs. Environmental controls and lead-safe work practices protect crews, waterways and neighbors.

Questions & Answers

Frequently Asked Questions

Under the National Bridge Inspection Standards, most bridges require inspection at least every 24 months, with shorter intervals for structures in poor condition or with specific concerns. Fracture critical members, underwater elements and special features can require different frequencies set by the owner.

We choose access methods that suit the site, including under-bridge units, rope access, boats, drones and dive teams. The goal is a close visual and tactile examination of critical elements, with the least disruption to traffic and the environment.

We notify the owner immediately, provide photos and measurements, and discuss interim steps such as lane restrictions, load posting or emergency shoring. A full written report follows, but safety-critical conditions are never held until then.

Yes. Our maintenance crews handle many common repairs, from joint and bearing replacement to deck patching and steel repair. For major rehabilitation, we can support design engineers and agency procurement with constructible, field-verified details.

Element-level inspection breaks a bridge into components such as girders, bearings, deck and piers, then records quantities in defined condition states. It gives owners more precise data for preservation planning than a single overall rating and supports better cost forecasting.

We collect the field data and condition information that load ratings depend on, and we work alongside licensed engineers who calculate rating factors. Where the rating shows limited capacity, we help evaluate posting, restrictions or repair options.
