How It Works

Bridges and culverts rarely fail without warning. The signs are usually visible years ahead, if someone knows where to look.

We inspect every component, photograph every finding, and translate it all into a report you can plan around. Fewer surprises. Smarter budgets. Decisions you can stand behind.

  1. Start With a Conversation

    Tell us about your property and what you need in a free 15-minute call. We'll set the scope before we ever arrive on site.

  2. Inspect Every Component

    We walk the structure, inspect it hands-on, and bring in a drone for steep banks, high decks, and long channels. Every defect is photographed and located.

  3. Receive Your Report in 5 Days

    You'll get a comprehensive technical report and an executive summary, written so your board or property manager can understand it in minutes.

  4. Track It Year After Year

    Annual inspections show you exactly how your structure is changing, so small issues get fixed while they're still small. Annual visits are 60% of the baseline cost.

Independent Advice You Can Trust

Carolina Infrastructure Assessment was founded by an NBIS-certified bridge inspection team leader to bring professional-grade inspections to the structures large firms often overlook.

We inspect. We don't repair. Our recommendations are never tied to a repair contract, so you can be sure every priority on your list is there because your structure needs it.

Sample Engineering Reports

Review the exact deliverables our inspectors produce in the field. Every assessment delivers both an executive summary for board voting and a comprehensive technical report for maintenance and engineering planning.

Questions Owners Ask

Straight answers about inspections, reports, and what to expect. Don't see yours? Give us a call.

Do private bridges and culverts need to be inspected?

In most cases, no one inspects them unless the owner arranges it. The federal inspection program covers public highway bridges, so bridges and culverts on golf courses, HOA roads, parks, and private property usually fall outside it. The owner is still responsible for the structure, and a professional inspection gives you a documented record of its condition and a plan for maintaining it.

What is an NBIS-certified bridge inspector?

NBIS stands for the National Bridge Inspection Standards, the Federal Highway Administration rules that govern how public highway bridges are inspected. An NBIS Team Leader has completed the required federal training and field experience to lead those inspections. Our inspections are led by Will Vaughan, an NBIS-qualified team leader with more than ten years of experience.

How often should a bridge or culvert be inspected?

Public highway bridges are generally inspected at least every 24 months under federal standards. Private structures have no required schedule, so many owners start with a baseline inspection and follow it with annual inspections to track changes over time. Annual inspections through our program cost 60% of the baseline inspection.

What are the warning signs that a culvert needs to be inspected?

Watch for dips, cracks, or sinking pavement above the pipe, water ponding at the inlet, erosion or washouts at the outlet, rust or bent sections in metal pipes, and cracked or shifting headwalls. Any of these can point to problems inside the structure that aren't visible from the road.

How much does a bridge or culvert inspection cost?

Cost depends on the type, size, number, and accessibility of the structures. We start with a free 15-minute call, then send a proposal built around your property within 1 business day. First-time clients receive 20% off through our Founder's Program, and annual follow-up inspections are 60% of the baseline cost.

What's included in the inspection report?

You'll receive a comprehensive engineering report and an executive summary within 5 business days. Every deliverable includes high-resolution photos of each defect and its location, standard condition ratings for each component, and recommendations ranked by priority so you know what to address now and what to budget for later.

How soon can you inspect my structure?

Most inspections are scheduled within 1 to 2 weeks of your first call, and we respond to every inquiry within 1 business day.

Do you perform repairs?

No. We only inspect. Because our recommendations are never tied to a repair contract, every priority in your report is there because your structure needs it.

Why do you use drones during inspections?

Drones let us document areas that are difficult or unsafe to reach on foot, including steep banks, high decks, long channels, and upstream and downstream waterways. All drone work is flown by an FAA Part 107 licensed pilot and included in your report.

What areas do you serve?

We inspect structures across North Carolina, Virginia, Maryland, and the Washington D.C. metropolitan corridor, with field dispatch hubs serving communities across the Mid-Atlantic and Southeast.
