Blog Post #2 – Trainee Geo-Environmental Engineer Cian Flynn

Posted on 26th October 2021

I am a student from the University of Portsmouth studying for a BEng Engineering Geology and Geotechnics…

Since my last blog, my logging skills have developed by weekly practice in the sampling room and working with engineers to understand how the logs are used in final calculations and reports.

For three out of five days a week, I have been logging samples recovered from windowless sampler and cable percussive boreholes, mostly from the in-house Premier rigs.

Following the description of the soils recovered I ensure that appropriate, representative sub-samples are taken, depending on the job-specific geotechnical and geo-environmental requirements. These sub-samples are then stored carefully in strict accordance with internal procedures.

Beyond this, my responsibility in the sampling room also includes managing the freshly recovered sample liners that are delivered daily to the Winchester office by our site technicians and drillers. This includes recording the job details ready for logging. Once sub-sampled, the project engineer then schedules the required laboratory testing and I ensure that the correct samples are dispatched to the relevant laboratory and complete our chain-of-custody processes.

The remaining two days of the week are focused upstairs in the office where I have been introduced and trained to use HolebaseSI to convert the logging data outputs into a neat PDF visualisation of the borehole. I have also begun to look at Desktop Studies, Ground Investigation Reports and Agricultural Land Classification Reports.

I have also managed to get out of the office and on site, accompanying a colleague for a site walkover and a day of Trial Pit soakage testing in accordance with BRE:365 in order to inform drainage design.

I’m looking forward to learning more of what Soils Limited have to offer in the coming months, expanding my knowledge and own personal experiences in the GI sector.
