\n<\/div><\/div>\n\n
\n

The construction industry operates in an environment where every centimeter counts, every deadline impacts costs, and every decision relies on reliable data. Roads, buildings, energy corridors, industrial facilities, and urban projects all require a detailed understanding of the terrain and volumes to mitigate risks, optimize design, and control costs.<\/p>\n<\/div><\/div>\n\n

\n

Balko, with its modular drone-based solution, enables the collection of precise and consistent 3D geospatial data, transforming traditional surveying methods often hampered by accessibility issues, time constraints, or risks to field teams. The modular Connectiv system integrates laser scanners, inertial navigation units (INS), and specialized cameras into a single compact platform, providing comprehensive and efficient data collection during a single flight.<\/p>\n<\/div><\/div>\n\n

Volumetric monitoring of materials and earthworks<\/strong>  <\/strong><\/strong><\/h3>\n<\/div><\/div>\n\n
\n

3D geospatial data enables the precise measurement of earth volumes excavated, stockpiled, or moved on the construction site. These measurements allow for comparison of completed work with design plans, preventing calculation errors, reducing cost overruns, and optimizing material usage. Continuous volumetric monitoring facilitates planning of subsequent phases and cost control.<\/p>\n<\/div><\/div>\n\n

Site monitoring and security<\/strong>  <\/strong><\/strong><\/h3>\n<\/div><\/div>\n\n
\n

Drones equipped with geospatial sensors provide secure monitoring of construction sites, collecting data from the air and preventing teams from being exposed to dangerous or difficult-to-access areas. They make it possible to detect unstable slopes, hazardous traffic areas, and anticipate dangers related to machinery and equipment on site, while optimizing travel logistics.<\/p>\n<\/div><\/div>\n\n

\n

A good balance between coverage, point density, and handling of mixed environments. When used on a drone, it allows for the rapid monitoring of large construction areas, the detection of changes, and the identification of potential risks.<\/p>\n<\/div><\/div><\/div><\/div>\n<\/div><\/div>\n\n

As-built documentation and BIM\/GIS integration<\/strong>  <\/strong><\/strong><\/h3>\n<\/div><\/div>\n\n
\n

At the end of construction, geospatial data is used to create accurate as-built documentation, integrating the final state of the structure into a digital model that can be used for maintenance, operation, or future renovations. These deliverables enrich BIM models and GIS systems, ensuring a reliable foundation for the entire infrastructure lifecycle.<\/p>\n<\/div><\/div>\n\n

In the construction sector, photogrammetry allows for the precise documentation of site progress and the apparent condition of structures. Photogrammetry is particularly relevant for producing orthophotos of construction sites, visually inspecting facades, and creating visual as-built deliverables. Combined with LiDAR, it complements metric data with realistic information, enhancing the integration of surveys into BIM and GIS workflows.<\/p>\n<\/div><\/div>\n\n
