A municipal bridge that has not been inspected on schedule is not just a deferred maintenance problem — it is a public safety liability sitting in plain sight. The I-35W collapse in Minneapolis and the Fern Hollow Bridge failure in Pittsburgh share the same root cause: inspection findings that were not connected to a capital decision fast enough. Book a demo to see how Oxmaint manages municipal bridge inspection programs.
A municipal bridge inspection program is a structured system covering routine 24-month FHWA inspections, fracture-critical and underwater inspections at tighter intervals, NBI condition rating documentation, load rating calculations, and capital improvement prioritization — all connected so that field findings translate directly into defensible budget submissions. Oxmaint automates scheduling, routes inspection work orders to qualified inspectors, captures NBI ratings in structured digital fields, and generates condition-scored bridge capital plans that councils and federal funding administrators accept.
Oxmaint automates every bridge inspection interval, routes NBI documentation to qualified inspectors, and produces federal audit packages before deadlines — not after violations.
| Inspection Type | Required Interval | FHWA / NBI Standard | What Oxmaint Captures |
|---|---|---|---|
| Routine Inspection | 24 months maximum | 23 CFR Part 650, AASHTO Manual for Bridge Evaluation | NBI element condition ratings (0–9), superstructure, substructure, deck scoring, inspector attribution, photo evidence |
| Fracture-Critical Inspection | 24 months — hands-on | FHWA Fracture-Critical Inspection Techniques for Steel Bridges | FC member condition, crack mapping, hands-on access documentation, qualified inspector certification records |
| Underwater Inspection | 60 months maximum | FHWA Hydraulic Engineering Circular No. 23 | Scour condition, foundation integrity, diving or ROV inspection records, scour action plan documentation |
| Special Inspection | As required by findings | State bridge inspection manual, engineer-of-record recommendation | Specific deficiency monitoring, interval set by inspector, linked to originating routine inspection finding |
| Damage Inspection | Immediately after event | FHWA Emergency Inspection Guidelines | Impact or flood damage documentation, load restriction decisions, emergency repair work order generation |
| In-Depth Inspection | As determined by program | AASHTO MBE, state DOT supplemental guidance | Detailed element-level findings, non-destructive testing results, load posting recommendations |
The National Bridge Inventory uses a 0-to-9 condition rating scale for deck, superstructure, and substructure. Oxmaint captures these ratings digitally in the field and converts them into the condition-scored capital priority rankings that councils accept as investment justification.
No action required. Scheduled routine maintenance and next 24-month inspection confirmed. Asset tracked in Oxmaint with next inspection date auto-generated.
Minor deterioration noted. Preventive maintenance work orders generated. Bridge flagged for enhanced monitoring at next routine cycle. No load restriction.
Advanced deterioration. Bridge enters capital priority queue with condition score and consequence-of-failure weighting. Special inspection interval triggered automatically.
Immediate action required. Load posting or closure work order generated and routed to engineer of record. Emergency capital submission package produced on demand.
From bridge inventory setup through annual FHWA compliance reporting — four integrated steps on one platform.
Every bridge registered with structure number, BMS ID, material, year built, span configuration, load rating, ADT, and replacement value. Inspection type requirements flagged per structure — fracture-critical, underwater, load-posted. QR codes assigned for field inspector mobile access.
Routine, fracture-critical, and underwater inspection work orders generated automatically per FHWA interval. Inspectors assigned by qualification. Overdue alerts escalate to program manager at 30, 14, and 7 days before interval expiry — no missed inspection cycles.
Inspectors complete NBI element ratings, condition notes, and photo documentation directly in the Oxmaint mobile app — offline-capable for remote structure sites. Data flows directly into the NBI record without manual transcription. Inspector certification and signature captured per inspection.
Condition scores and consequence-of-failure weighting produce a ranked bridge capital queue updated after every inspection cycle. FHWA compliance report, NBI submission data, and capital improvement plan export in one click — formatted for state DOT submission and federal funding applications.
Oxmaint handles NBI rating capture, FHWA interval compliance, and capital prioritization in one platform — built for municipal public works teams, not DOT-scale enterprise software.
Bridge inspection compliance requirements vary by country and jurisdiction. Oxmaint meets applicable standards across all major operating regions. All data is encrypted AES-256 at rest and TLS 1.3 in transit.
