The technology behind nation-building.
According to a McKinsey study, the construction industry struggles with high levels of inefficiency. Large construction projects typically take 20% longer than expected and are up to 80% over budget. UAV-as-a-service can be used throughout the lifecycle of a construction project, from feasibility and tendering to delivery and maintenance.
Geological surprises are a major reason why projects are delayed and over budget. Discrepancies between ground conditions and early survey estimates can require costly last-minute changes to project scope and design. New techniques integrating high-resolution photography, 3-D laser scanning and geographic information systems, enabled by recent improvements in UAV technology, can dramatically improve accuracy and speed. They can also help stakeholders survey efficiently to avoid post-construction financial liabilities due to lack of maintenance and resulting environmental damage.

UAVs provide construction stakeholders with expansive, accurate, and precise spatial data. The data obtained through a UAV can be analyzed with engineering software and furthermore, can be overlaid on construction drawings. The data captured via each flight is processed through photogrammetry software which is then used to create digital elevation models (DEMs), orthophotos, and 3D point clouds. A variety of secondary data products such as shapefiles, contour lines, and raster products are created when imported into a geographic information system (GIS). Furthermore, the overlaying of spatial data on CAD/construction drawings allows professionals to compare ‘as designed” to “as-built”, thus enabling the identification of spatial mistakes well before they are executed on-site.
Railways
UAV in Railways can help in increasing the security by regular surveillance of the stations and the railway tracks. UAVs can also be used in regular track inspection, bridge inspection, thermal inspection, construction monitoring, structural inspection, 2D and 3D modelling.
