A (humorous) story about a job that went badly and what you learned: 

Testing water quality in a stream nearby to a project, I discovered the water pH was very low. After a week of trying to find the source, and numerous visits from environmental engineers, we discovered that the water sampling bottles were sterilised with sulphuric acid. I learned that if something doesn’t seem logical, there is probably a good reason for it, so you should keep investigating and don’t rule out the simple things.


Bachelor in Engineering Technology (Civil) and Diploma in Civil Engineering.

Interests outside work: 

Motorsport and Football.
