The GRS uses high-level, cutting-edge equipment that allow it to return results of high accuracy and reliability.
WIDE AREAS SURVEY
The survey of large areas is intended to develop the preliminary study and groundwork design, as well is used as a base map for GIS and BIM. .
Usually, the generated mapping is developed from satellite or aerial photogrammetry images, geo-referenced through GCP (Ground Control Point) and acquired through the total station or GNSS systems.
HIGH PRECISION MONITORING
The high-precision monitoring of civil structures allows the identification of movement for sub-millimeter scales of sizes as well as the evaluation of the vertical and the eccentricity of buildings' pillar
Monitoring activities are carried out through measurements on target with total stations and high precision levels or through the analysis of high density point clouds acquired by 3D laser scanner.
INVESTIGATION OF STRUCTURAL FEATURES
Ground Penetrating Radar makes possible to investigate, in a non-destructively way, the size of the pillars, slabs and concrete bases in civil structures. Evaluation of data highlights the presence of the reinforcement rod, identifying the type and step as well as highlight any cavity or differences in the structure itself.
Geophysical and structural characterization of pillars are developed through the instruments GPR and 3D laser scanner.
EVALUATION OF GEOTECHNICAL CHARACTERISTICS OF PAVIMENTS
This type of evaluation allows to know the characteristics of bearing capacity both for individual layers forming the structure road/airport and for the mechanical response of the whole pavement.
During the construction of the pavement, characteristics of granular or weakly bound material are monitored by tests through LFWD and DCP
The elastic modulus of the individual layers of the pavement structure as well as the value of the PCN of runways and taxiways are measured using HFWD assisted by the thickness information acquired through ground-penetrating radar and coring calibration.
RECONSTRUCTION OF UNDERGROUND NETWORK PIPES
The identification of networks of underground pipes allows the proper maintenance of the facilities and presents a preliminary reduction of risks in the event of excavations, holes and interventions of all kinds.
The identification of these networks is made by the direct inspection of the manhole assisted through the geophysical instruments GPR.
The measures of retro-reflectivity tests the characteristics of RL (Retroreflected Luminance) and QD (Luminance coefficient under diffuse illumination) of paints used on airfields, in compliance with the ENAC and ICAO requirements.
The measures occur through the use of a georeferenced retroreflectometer.
The topographic plans generated through detailed survey are the base of maps used for the detailed design.
Through GPS, total station and laser scanner, it is possible to create spot height map and point clouds to extrapolate DTMs (Digital Terrain Models), sections, plans and profiles.WGS84 survey allows the creation of obstacles airport database in compliance with ICAO regulations.
