Decision making in engineering demands a logical process that is well documented. Particularly if you are selecting a new site for a mine waste disposal facility.In 1983, Andy Robertson and I wrote a paper available at this link on site selection. The ideas were based on what we did to locate the site of the tailings facility for the then new Greens Creek mine. The site was selected and is still in use. (more…)

I have moved on from countries and companies. I have left (and re-entered) countries. I have left companies and joined the principals in other companies. I have, in a word, moved around. At 67, I spend no time cogitating on these past decisions. With so long a history of making decisions and moving on, I have so much to regret that I would go crazy thinking what would have been had I not made those many decisions. It is futile to regret a past decision that may have been the wrong decision. (more…)
A picture of a 1,000-year old earthen mound in Central America.
Goes to prove geotechnical structures can endure stable for at least that long.
Today I explained the differences between Failure Modes and Effects Analyses (FMEA), Value Engineering (VE), Multiple Accounts Analysis (MAA), and Risk Assessment (RA) to some unfamiliar with any of these tools to support engineering judgment as the basis for decision making. In so doing, I had to go back to basics and thus myself uncovered a new and deeper understanding of the basics. (more…)

I learnt today that Geoff Blight has passed away. I can pay tribute to him best by writing of those times I worked with him. He was a professor at the University of the Witwatersrand. He came in and took over when Professor Jennings died. I never had a lecture from him, so I leave it to others to record his lecture style and teaching abilities–both of which I was told were superb.
