GEOTECHNICAL MACHINERY FLEET

The field testing and sample taking phase are of great importance within the phases comprising a geotechnical study. To guarantee the control and reliability of this work, CODEXSA has its own resources to perform it.

The personnel that handles the equipment is salaried and has ample experience conducting these activities.

Over the years, the fleet of machinery has been expanded with increasingly more versatile resources that enable us to act in different situations. So we have wheeled equipment, equipment with chains, light equipment, etc.

The latest addition to our machinery fleet is a TP-60/300 probe that, due to its small size, is quite useful in difficult to access works and enables us to probe in urban quarters. We are thus able to reach sites that other equipment cannot.

CALIBRATION OF PROBING EQUIPMENT:

REAL SPT ENERGY

CODEXSA has calibrated the SPTs of each of its units to thus obtain the appropriate energy correction factor. This factor depends on the type of machine and the specific drop hammer falling system, its value therefore resulting greater than the unit. This implies that, if this correction is not available, the land's resistance would be underestimated. This would entail an overestimate of the foundation and other structural elements, and therefore, a lack of economic efficiency in the project.

Calibrations have been performed according to standards UNE-EN ISO 22476-3:2006 and ASTM D4633. A dynamic pile driving analyzer (Pile Dynamics PAL-L) and a pile driving bar instrumented with two extensimeters and two accelerometers. The data recorded have been analyzed via the specific software called PDA-W (Pile Dynamics) to obtain correction factors for each unit.
