Dave’s Construction Diary

Commentary from Dave Dube’ on Persimmon’s Greens and Bunker Renovation Project

Work on Persimmon’s greens and bunkers began promptly on Tuesday, May 20th when the course closed.  We are now not quite two weeks in and the progress has been impressive.

I like to think about this project in three phases, destruction, construction and completion. Right now we are between the destruction and construction phase, depending on where you look on the course.

During destruction we spray out the turf to be removed from greens and collars, measure original contours using specialized GPS instrumentation, remove roughly 3” of underlying soil and “rip” the remaining soil to remove roots and other debris. With the bunkers, destruction means removing old sand and reshaping the bottoms as needed.

Construction phase on greens starts with the addition of 3” of new greens mix for both the collars and the greens themselves. This is followed by “shaping” the mix to match the original contours, except where the Course Architect directs an adjustment. For the bunkers, construction includes rebuilding or adding drainage as necessary, then adding a specialized gravel layer that when combined with application of the Billy Bunker polymer, will form a hard shell liner designed to keep contaminants out of the bunker, but allow irrigation and rain water to drain through the sand.

As of now all 18 greens, plus the practice greens have been sprayed out, and the sod and subsoil stripped from holes 1 through 5, plus 7 and 9/18. We are just now starting the construction phase on these same holes, with the addition of greens mix and verifying of contours. Greenside bunkers on holes 1 through 5 are already mostly in construction phase with new drainage and the application of gravel in progress.

We have achieved a tremendous amount in the first couple of weeks. Here are pictures, giving you a sense of what’s going on. I hope to update this diary a semi-regular basis, so visit the home page regularly and check out our latest photos.
