As mentioned earlier, I have been working on retaining walls for a few days. A couple of days ago (when the wall parameters were really strict), my dad came up to me and was telling me about some of the information my father-in-law gave him when they were visiting a couple of weeks ago.
Apparantly, my father-in-law told my dad about how they used to use MathCAD for completing calculations (like retaining walls). He kind of suggested we look into such a program for our design.
Let me just say that retaining wall calculations, while confusing and long aren't impossible to do by hand or in Excel. And MathCAD costs LOTS of $$$$. And we are in a recession, with shrinking staff. Why on earth would we spend lots of money on a program we DON'T need?
My in-laws do this ALL THE TIME! You don't ask for their opinions, but they tell you anyway.
My mother-in-law has done it before with when we should have children. I dare her to give me her opinion on that again. I'd love to give her my opinion on her opinion. :)
Love, Mrs. Janney
