Infrastructure and Transport Sector
Surveying and construction control for roads, railways and tunnels
We survey road and rail corridors for the detailed design study, set out the works during construction and finish with the As-Built of the road or railway, its bridges and its tunnels.
A road is designed on a survey, built from the setting out and paid for on measured quantities. If the three do not start from the same geodetic control, the difference shows up in the progress payment. We work at all three stages for road and rail concessionaires, contractors, engineering consultancies and infrastructure operators.
For the design study we fly the corridor with airborne LiDAR, at ±5 cm absolute accuracy. To set out and control the works we use total stations and GNSS. Under a bridge or inside a tunnel, where airborne LiDAR cannot reach, we scan from the ground.

Where we work in infrastructure and transport
Road corridors and national highways
LiDAR corridor surveys, terrain models and mapping for design and construction.
Expressways and regional roads
Geodetic control, setting out and geometric verification during construction.
Railways and stations
Mobile scanning of track, clearance envelopes, platforms and structures, with As-Built models.
Tunnels
3D laser scanning of the cross section, overbreak control and dimensional verification.
Bridges and viaducts
3D modeling, As-Built control and deformation monitoring of the structure.
Interchanges
Digital terrain models and earthwork volume calculations.
Logistics terminals and port infrastructure
Surveys of yards, warehouses and access roads, with a geospatial asset inventory.
Four business lines, from planning to monitoring
Plan, design, build, operate and monitor. The same four lines in every sector, with the activities and deliverables that sector needs.
