As we’ve noted in other posts, CPT provides a number of benefits over traditional methods of subsurface soil characterization. These benefits include:
Traceability
Reports from a specific sounding are easily traced back to the source data, and because CPT is a continuous process, data points in between those reported can be evaluated post-test. This is in contrast to geotechnical boring where individual samples need to be tracked and accounted for from the busy worksite to a remote lab and through to reports and documentation. This can be cumbersome and prone to errors.
Immediacy
Reports can be generated in near-real-time. This enables customers such as site owners or civil engineers to have visibility to the tests as they are occuring. Having immediacy means that as data is reported and interpreted, any retesting that should be done or any additional soundings that would be useful to clarify or validate data can be called for on the spot.
Accuracy
Because of the very large volume of soundings that have been done, important factors and relationships have been established that enable the raw CPT data to be translated into useful information. Additionally, as we’ve noted elsewhere, CPT leaves the soil being tested ‘undisturbed’ and therefore provides a more accurate assessment than other methods of soil characterization.
CPT Data analysis and interpretation can be aided through the use of specialized software
Two that our customers have had success with include DataForensics & Datagel. Using software to log, analyze and report your data provides a number of advantages. Traceability, immediacy and accuracy are improved. Additionally, efficiency and therefore your cost structure, benefit as well. With the right software you are able to accelerate your ability to serve customers both more quickly and more accurately.
If you are entering or have recently started out in the CPT business, we encourage you to investigate the two companies noted above to begin to learn about their products and how they work. We also encourage you to reach out to Vertek CPT and we’d be happy to walk you through any and all aspects of your prospective CPT business infrastructure.
