Pat:
"Wouldn't that indicate that none of them got it right ?
That all three methods were flawed ?"
Maybe, although I don't consider leaving the sand alone (basically not doing much of anything until it has settled) to be a flawed method, I call it being smart until such time the super can confer with the architect, or other supers who have experienced the same sand.
"I'm curious as to how the removal of one type of sand, and its replacement by another type of sand can cause problems.
It seems counterintuitive.
Unless, the bunkers were all rebuilt.
If that's the case, then the three problems you cite aren't so isolated, as a number of clubs seem to encounter the same difficulty, which leads me to conclude that the bunker construction is faulty."
I have no idea who you really are (your backgroud that is with respect to golf design, construction or maintenence for that matter) but in your statement above, you are starting to sound a bit like some of the members I have to deal with.
The bunkers were all redesigned and rebuilt on the 3 courses in question...not sure that will satisfy you however. How in the world do you conclude the construction of the bunkers would/could be faulty based on the superintendent having some problems achieving the correct playing characteristics? Curious, do you think it is possible that the super simply didn't have any experience with the sand type chosen by the club or that possibility he wanted to leave it alone for a while, so as not to start in the wrong direction, or, knowing his membership, he thought it wise to take a wait and see approach and work it out slowly with his green committee or the architect?
"The next question is why is it faulty, what about it causes clubs to experience ongoing problems ?"
I think the mere fact that the sand they had was so old and poor to begin with and now the new sand is so much better and different (performance specs & characteristics) the supers had a method to 'deal' with the old sand for so many years and the new sand requires a different technique that they are/were presently unfamiliar with.
"With respect to the three clubs you reference,
What was so different in their approaches ?
What caused all of them to have problems ?
Was it the sand, or was it the container, the construction and mold of the rebuilt bunker ?"
Pat...you know what, there is so much that goes on behind the scenes (even with a simple bunker reconstruction project) that there aren't enough hours in the day for me to explain it to you in writing. Besides, based on what I have experienced in reading this site and the nature/understanding of your questions, I can't take the time...I have enough of a challenge explaining these matters to my clients/owners...you see, they are the ones writing my checks
Pat, I am not upset...I just need to move on
P.S. thanks for using green this time, it is my favorite color
