Comprehensive Inspections, Actionable Insights, Smarter Maintenance
Sentra pairs drone-based HD and thermal inspections with high-fidelity sensors, edge gateways and AI to rapidly detect, classify and quantify cracks, spalls, corrosion and hidden defects—delivering near-real-time condition scores and digital-twin visuals. Fusing these outputs yields probabilistic RUL estimates, risk-ranked maintenance plans and CMMS-ready work orders, enabling faster, safer inspections and lower long-term repair costs.
Overview
At Sentra, we help infrastructure owners, contractors, and operators monitor the health of structures through purpose-built IoT systems. From deploying GNSS meters and tilt sensors to running edge AI for instant anomaly detection and feeding digital twin dashboards, we deliver an end-to-end service tailored to your asset type and risk profile. Whether you need short-term construction monitoring or permanent asset surveillance, our solutions scale from single-structure deployments to city-wide sensor networks.

Got Questions? We've Got Answers.
We provide end-to-end bridge inspections using drone aerial surveys, underwater ROV/sonar (with divers when needed), and hands-on superstructure/deck testing. Our certified teams combine high-resolution imaging, NDT and live-load monitoring to quickly detect scour, cracks, corrosion and section loss, then deliver clear, standards-compliant reports with prioritized repair recommendations.
Federal regulations require routine bridge inspections at least every 24 months, though most are done every 1–2 years. Bridges with poor condition ratings may need annual checks. We help owners set the right inspection cycle based on traffic, environment, and past performance.
The right inspection depends on your bridge’s design, age, condition, and environment. Our team reviews these factors and recommends the best mix—drones for aerial views, sonar/divers for substructures, and hands-on checks for decks and bearings. We tailor each plan to your safety, maintenance, and budgeting needs.
Absolutely. We tailor each inspection project to your specific needs. If you only need a drone survey of the deck, we can do that. If you require a full assessment (drones, divers, under-bridge access, etc.), we’ll assemble the right team and equipment. We’ll discuss your objectives and constraints (time, budget, site access) and build a custom plan. Whether it’s a one-time inspection or a routine program, our goal is to provide exactly the services you require.
Yes. We have experience inspecting small local bridges, large highway and interstate spans, rail bridges, truss bridges, and more. Our equipment and team scale to the job: we use portable drones and lifts for tight sites, and barges or cranes for large or water crossings. Whether it’s a rural overpass or an urban multi-span viaduct, we have the expertise and tools to perform a safe, thorough inspection of any structure.
Each inspection comes with a detailed report including photos, videos, condition ratings, and descriptions of defects. It summarizes severity, tracks changes from previous inspections, and complies with AASHTO/NBIS standards, giving you clear, actionable insights for compliance, maintenance, and repair planning.
