Safe, fast, and highly detailed drone-based inspection of road bridges, railway bridges, flyovers, and overbridges — detecting cracks, spalling, corrosion, and structural defects without scaffolding, lane closures, or danger to inspection teams.
Traditional bridge inspection requires under-bridge inspection vehicles, rope access teams, or scaffolding — all of which are expensive, time-consuming, and require complete or partial lane closure. Our drone inspection eliminates all of these barriers, delivering close-up imagery of every surface — including undersides, girders, and piers — with no disruption to traffic and no risk to inspectors.
A bridge inspection that costs ₹8–15 lakhs with a conventional UBIV team and takes 3–5 days with lane closures can be completed by our drone in 4–8 hours at a fraction of the cost — with equal or better defect detection.
Hairline to wide cracks in deck slab, beams, piers, and abutments — width, length, and orientation mapped with GPS coordinates.
Surface layer separation and spalling of concrete cover — thermal imaging reveals subsurface delamination not visible to RGB cameras.
Rust staining patterns indicating rebar corrosion and carbonation — mapped across the entire bridge surface for maintenance prioritisation.
White mineral deposits indicating water seepage and leaching through construction joints, cracks, and poorly sealed surfaces.
Deteriorated elastomeric bearings, failed expansion joints, and blocked drainage outlets detected from close-range aerial inspection.
Riverbed scour around bridge piers and abutment foundations — erosion extent mapped using drone imagery and bathymetric data.
Impact damage, missing sections, and structural weakening of parapets, crash barriers, and pedestrian railings along the bridge deck.
Pre-stressed girder cracking, soffit spalling, and web defects in the underside of the bridge superstructure — inaccessible without drone.
National and state highway bridges — PSC girder, RCC box, arch, and cable-stayed bridges. Full inspection including deck, soffit, piers, bearings, and abutments.
Railway bridges, viaducts, and ROB structures — girder inspection, pier condition, bearing assessment, and superstructure monitoring for Indian Railways and metro authorities.
Urban flyovers, elevated corridors, ROBs, and foot overbridges — inspection in congested areas where conventional methods require complete traffic blockade.
River-crossing bridges with scour inspection, pier condition assessment below waterline, and flood damage evaluation after monsoon events.
Cable inspection, pylon and tower condition, anchor block assessment, and deck inspection for cable-stayed and suspension bridge structures.
Condition documentation of heritage and aging bridges for load capacity assessment, repair prioritisation, and structural rehabilitation planning.
We review bridge drawings, previous inspection reports, span lengths, and known problem areas to plan optimal drone flight paths for complete coverage of all structural elements.
DGCA airspace clearance, NHAI/PWD NOC, and site safety protocol are established. Traffic management — if any — is minimal and limited to soft closures if needed for extreme close-up work.
RGB at 2–5 cm GSD for crack detection, thermal for delamination, and 4K video for documentation. Drone systematically covers deck top, soffit, all piers, abutments, bearings, and expansion joints.
Photogrammetric processing creates a complete 3D model of the bridge structure — enabling deformation analysis, precise defect measurements, and future comparison surveys.
All defects are identified, classified by type and severity, measured, and GPS-tagged. A condition rating is assigned to each structural element as per IRC SP-40 guidelines.
Full bridge inspection report with defect maps, 3D model, thermal analysis, element condition ratings, and prioritised maintenance recommendations — delivered within 48–72 hours.
