4 Road Life-cycle Planning / Design Construction Operation and Maintenance

5 Stage wise Applications Planning / Design Topographic Survey Alignment Geometry L-Sections, C-Sections Quantity Estimates Utility Re-location Bathymetric Survey Bed Profile HFL (High Flood Level) Invert Level Underground Mapping using Ground Penetrating Radar (GPR)

6 Stages of Road Life-cycle Construction Project Monitoring Level Survey (Cut and Fill) As-built Structures Operation and Maintenance Condition Mapping Pavement Condition Index (PCI) International Roughness Index (IRI) RAMS (Road Assets Management) PMS (Pavement Management System) Bridge / Structural Inspections

7 Conventional Survey

8 Why Modern Techniques? Labor Intensive Time-consuming Expensive Dictated by conditions (time of year, sun angle, weather, etc.) Approachability Safety of the Personnel

9 Modern Geospatial Technologies LiDAR Ground Penetrating Radar Retro-reflective performance study Pavement Scanning Dynamic Plate load Asset mapping by Mobile Photogrammetry Aerial Photogrammetry & LiDAR Multi-beam Bathymetry (underwater)

10 LiDAR (Light Detection And Ranging) Terrestrial Survey grade Mobile LiDAR All terrain Mobile LiDAR Mapping Mobile Mobile LiDAR on boat Mobile LiDAR on rail track cart Aerial Push cart LiDAR Mapper Back pack mobile LiDAR

11 LiDAR (Light Detection And Ranging) Terrestrial Mobile Aerial Aerial LiDAR carrier LiDAR on Mini UAV platform

12 LiDAR (Light Detection And Ranging) Mapping Grade Corridor study and planning surveys Asset inventory and management Environmental Surveys Sight distance analysis Earthwork Surveys Urban mapping Coastal zone erosion analysis Survey Grade Mapping grade application + Engineering topographic surveys As-built surveys Structures and bridge clearance surveys Deformation surveys Forensic surveys Engineering Grade Mapping grade application + Survey grade application + 3D Modeling of pavement Transverse and Longitudinal Evenness Rutting Analysis Drainage Analysis

13 Aerial Photography Aircraft DMC II 230 Camera DMC II 230 Camera Number of camera heads 5 PAN : Color Resolution 01:02.6 Frame rate 1.8 sec Color channels R,G,B, NIR Power consumption 350 W Altitude non pressurized 8000 m Resolution per pixel 14 bit MS pixel size 7.2 µm PAN GSD@500m 3.0 cm

14 Aerial Photography UAV / UAS

15 GPR (Ground Penetrating Radar) SYNONYMS Ground Probing Radar GeoRadar Surface Penetrating Radar (SPS) Uses Electro magnetic signals to locate buried objects Many diverse designs and operation methods, but works with transmission of electromagnetic energy (usually a pulse), and the detection of a small amount of that energy reflected from the target The time delay of the reflection contains information on the range of the target.

16 GPR (Ground Penetrating Radar) How Image is produced The round-trip transit time of the pulse emitted by the GPR and its reflection provide range information on the target

17 Time of flight GPR (Ground Penetrating Radar) Image Produced by a point Target Antenna Antenna position

18 Time of flight GPR (Ground Penetrating Radar) Image produced by linear object Antenna position

19 GPR (Ground Penetrating Radar) Typical Output from GPR survey 3D CAD map Multi-channel data visualisation

20 Bathymetric Survey Major Rivers Streams Deep Waters

21 Road Asset Management System (RAMS) Mapping of all Road Furniture and Assets Creation of Database Dashboard for Planning the maintenance Activities

22 Road Asset Management System (RAMS) POINT OBJECTS LINE OBJECTS AREA OBJECTS BOLLARD BRIDGE POINT CABLE BOX CULVERT ELECTRIC POLE LIGHT POLE MILESTONES PLACES OF WORSHIP ROAD LANE MARKING POINT TOWER TREE PLACE OF STAY BRIDGE EXTENTS BUILDING EDGE CURB STONE GUARD RAIL ROAD LANE MARKING TRAFFIC PROTECTION GRID WALL ROAD DRAINAGE BUS STOP CROSSING SECTION DIVIDING STRIP ENTRY AND EXIT GREEN AREA PARKING LANE RAILWAY CROSSING ROAD LANE ROAD LANE MARKING AREA SHOULDER SIDE ROAD SIDEWALK SKY WALK

23 Pavement Management System (PMS) Tool for planning the maintenance and repair of a network of Roadways. Can plan the budgetary projections to optimize the maintenance costs Monitoring the PCI (Pavement Condition Index) Monitoring the IRI (International Roughness Index)

24 Bridge Inspection Detection of Structural Cracks due to wear and tear Bridge safety inspections Conventional Methods Rope Access Inspection. Under Bridge Inspection Vehicle

25 Bridge Inspection UAV / Drone Terrestrial Lidar
