Airborn LIDAR (Lasser Scanning)

For those projects located in areas of difficult access, high-risk areas and challenging environments, AIG Instruments offers LiDAR with specialized resources and advanced technology that adapts to your needs, this combination means we can support you anywhere you need it doing  topographic surveys with “High Precision within short time”

The massive data capture is constituted by a laser mounted on the bottom of a helicopter or airplane. Lasers pulses generate a terrain model represented by a cloud of geo-referenced points (3D), intensity and RGB values. From the points cloud we can extract accurately and automatically: buildings, trees, poles, cables, contour lines and other objects of interest.

The laser has the ability to pass through obstacles, thereby obtaining two digital models: the DTM (Digital Terrain Model) and DSM (Digital Surface Model) digital model of the area, including all obstacles. It has a speed, accuracy and density of information unobtainable through traditional techniques while maintaining very competitive costs.

 Applications

Static Load Test of Piles

During the construction phase, it is essential to verify whether the estimates made in the design phase are appropriate in the area of interest. AIG Instrumentos offers verify soil bearing capacity for deep foundations by static load test of piles.

During the test, the pile is subjected to generally higher than those that will be in service in order to know their actual behavior in the field, in order to adjust the design to reality loads, following recommendations by international standards and needs of the project, allowing to know the level of deformation and stability of the foundation, in addition to the safety factor. In most cases, this cost saving.

The loads are applied with hydraulic jacks, with electronic or mechanical measuring settlement of the pile top devices. Often check load transfer to the ground by shaft or tip, measuring the tension of the pile at different depths.

Pile integrity Sonic method

During the construction phase it is essential to know the integrity of the piles, for that matter we offer a quality control through the sonic method generating “pile’s real information” determining the continuity of it and possible defects that could jeopardize the supporting ability of the the pile.

The sonic method is also known as Echo Test, Pulse Test,  Impulse Response consisting of hitting the top of the pile with a plastic hammer of low weight, the blow induce a wave that is reflected at the bottom of the pile and sensed by an accelerometer that digitizes the data, which are then processed by the PET software.

Using acceptance and rejection criteria, anomalies or representative peaks are classified to identify concrete failure generating results and interpretations of possible failures in the pile.

This test is usually performed to pile groups so we can correlate the information obtained with the information and design parameters.

Everything is performed under ASTM standards.

Pile Integrity Cross Hole Ultrasonic Testing

The piles are responsible for transmitting to the ground the loads they receive from the structure upon them, if the piles fail the risks are great, for these cases we offer “pile’s real information by 2D models “ through the pile integrity ultrasonic method.

Ultrasonic Tests are one of the most complete tests available on the market to determine the integrity of piles cast in place. The method is based on recording the time it takes an ultrasonic wave to propagate from a transmitter to a receiver moving simultaneously by two parallel tubes subject to the pile.

In case there are defects in the path of the waves such as inclusions or other they are recorded including the type of variation and depth of occurrence. For this test, it is essential that during the construction of the piles 2 or 4 tubes are left installed.

During processing, using rejection and acceptance criteria, anomaly classification is generated to make decisions that meet design standards.

Everything is performed under ASTM standards.

Down Hole / CrossHole

In AIG Instrumentos, we work by the hand of our clients combining different methods to offer practical solutions. During the design phase, we provide Down Hole and Cross Hole services, supported by geotechnical information of the area, committing ourselves to provide information about high resolution seismic properties.

Through the Down Hole and Cross Hole tests, we can obtain the propagation velocities of P and S waves on the ground, being this information of great interest to soil mechanical studies, foundation studies and design of earthquake resistant structures.

For both methods drilling is required. In Down Hole test, the study is performed in a single well, while for the Cross Hole test it is essential to perform the study in two or three wells.

ReMI / Seismic Refraction

AIG Instrumentos offers a wide range of engineering services, which means that we can meet the requirements of our customers, adapting us to their needs during the initial phases of the Project. For design, the dynamic parameters of the ground are indispensable to make the right geotechnical decisions concerning the foundation depths, seismic parameters, prospection of aquifers and also the delimitation of the shallower sub-soil layers. For all that we offer geophysical methods such as the ReMi method and seismic refraction, and because of their easy methodology they provide seismic properties in anyenvironment under a low cost and short time.

Depending on the condition of the study area, we’ll help you with the selection of the right method to apply. ReMi is recommended for urban environments and places where the presence of vibrations is high. But in case these conditions are not present, is recommended the seismic refraction where it is used an energy source as a sledgehammer or explosives.

We use advanced processing tools combined with analytical methods which allow us to present 2D models generated by the traveling times of the waves, identifying geological discontinuities of the soil attributed to faults, also its stratification, calculating the thickness of each layer and the rock-sediment contact in depth, this is in the seismic refraction method. In ReMi’s case, a frequency spectrum analysis of the surface waves is done, since they can be separated in surface waves and other kind of waves registered by the equipment; this allows the recognition of velocity’s true phase, obtaining with this the propagation velocity of the S wave with depth.

The laser scanning offers many advantages over the traditional methods of data capture:

  • Speed data acquisition.
  • Non-invasive method.
  • Does not involve stops in the processes of the plant.

Using this technology we can obtain point clouds of high density in real magnitude which will allow the generation of digital elevation models (DEM), contours and orthophotos which will make possible to perform millimetre calculations, slices, sections, entities vectoring, geometrically precised three-dimensional models in great detail to perform interference studies and calculating deformations.

All the generated information is compatible with CAD tools and the mainly design applications of industrial plants, such as: Smartplant 3D, PDS, PDMS, AutoCAD, Plant 3D.

Utility Locating and Mapping with Ground Penetrating Radar (GPR)

AIG Instrumentos gives value to your projects by offering a comprehensive and accurate view of buried services by Georadar or GPR (Ground Penetrating Radar), as a tool that saves time, money and even lives. The information provided will be key to making the right decisions; decreasing the chances of interfering with existing services depending on your location and fluid could cause additional costs on repairs and even tragedies in the case of ignoring its existence.

One of its most important advantages respect to metal detectors is that it has the ability to detect metallic and non-metallic pipes such as concrete and PVC. In addition to this, it can supply a depth and diameter of found objects, and can even determine the thickness of layers such as concrete, asphalt, geological strata, among others. Providing information in 2D or 3D drawings.

The computer emits electromagnetic waves to be propagated in the medium, until they reach an area or object whose electromagnetic properties are different compared to the surrounding or adjacent, the reflected wave is captured by the receiving antenna and is recorded in the central unit for further processing and interpretation.

The penetration depth depends on soil conditions and the frequency used. AIG Instrumentos offers diverse antennas and options that allow us to adapt to the requirements of our customers.

This service as geophysicist method is an indirect method but allows collecting valuable information. AIG instrumentos, in order to provide a service adapted to our customers’ needs, we complement the acquisition with the “Flow Detector” which allows to induce a magnetic field and follow pipes obtaining real location with greater depth. Our surveys are topographically geo-referenced to provide real coordinates with very little error range of detected services.
